Quilting on the knitting machine 1

ice-station.com.mx viagra SINGLE BED QUILTING for straight-edged pockets, hand technique only: leave needles OOW creating vertical ladders in location to correspond to side edges of pockets, have a loose tension row (at least 2 numbers higher, more if possible) to mark their tops. Both will serve to pick up stitches, loose rows help for the turning of any hem when joinings begin.

Knit half the length of the fabric required (create a small hem that will, in turn, be at the lower edge of the finished piece if preferred), continue knitting, picking up ladder loops closest to bottom turn prior to each pass of the carriage, continue until the loose tension row is reached, pick up all stitches as in a hem to seal the knit pockets, repeating the process throughout.

Hand technique combined with punchcard: slip stitches are a familiar tool in marking rows for picking up hems such as at the top of knitted skirts. They can also serve to create pick-up bars, and the slightly narrower, shorter lining for a quilted fabric. Nearly all stitches and rows in the card need to be punched, empty spots (non-selected needles) will skip, creating marking “floats” for rehanging after completion of the first half of the piece. KC pattern selection is on, part <—>. Non-selected needles on the second half of the piece will give a clue as to where to hang the floats, in turn bringing selected needles out to holding if desired. KC: needle selection is left on, no part buttons, the carriage is now set to knit every row throughout. The fabric will be knit together in those spots on the next pass of the carriage. Decisions can be made as to whether to do this every row or every other. A self-drawn possibility is below on the left in which instance all white squares would need to be punched out, a possible factory pre-punched on right. Not to be forgotten is appliqué, where separate shapes may be knit and joined onto the ground (knit in any desired stitch) technique by a seam as you knit method.

DOUBLE BED QUILTING: carriage settings on brother are for circular knitting. Cast on for every needle rib with a familiar yarn, knit one or 2 rows, and to make a trial piece, set the main carriage to slip to right, ribber carriage to slip to left. The ribber tends to knit tighter than the main bed since large numbers of needles will be knitting side by side, the tension should be loosened at least one or 2 numbers while on the main bed the tension used should be closer to that used for the same yarn when knitting stocking stitch. Bring every X needle on the main bed to hold position, knit 2 rows, and repeat to the desired length of the pocket. When the latter is reached, lower the ribber slightly, “stuff” pocket, bring all needles to hold position, the needle set up is with needles at halfway between each other (racking handle H as for every needle cast on ), so main bed may be brought to hold as well, knit 2 rows, and repeat process adjusting cam settings. The same principle applies here whether patterning is used or not. With slip setting non-selected needles (B pos) slip, do not knit, and needles in D position or holding in hand tech, will knit and in this fabric seal the fabric. In the chart, the symbols represent the stitches as they are formed on each bed to create a tube. The carriage icons show that opposite part buttons are in use on both beds. The ribber (odd-numbered, white rows) knits left to right, slips right to left, MB (yellow rows) slips left to right, knits right to left, creating a tube.

Automating the function brings us to another color separation of sorts. In single color quilting using simple tubular setting: Knitmaster machines work a bit differently than Brother, so cards/ mylars would have to be designed accordingly, Passap has some built-in techs that can help with this. The settings below are for brother, and the card, for narrow vertical tubes. The width between punched holes could be adjusted to any factor of and up to every 24. Every row or every other row can be marked. Cast on for every needle rib. In this repeat when rows with no needle selection occur at its top, set both carriages to knit 2 rows (or bring all needles manually out to hold) to seal pockets. MB is set to slip in one direction, will knit on even rows,  to slip on odd rows as punched. The ribber is set to slip from right to left and knit from left to right. With carriages at KM’s left insert the card, lock on row 1. KC –> knit 1 row in rib from left to right, release card, and continue knitting. In Brother machines, the tucking lever must be in the down, N position as well. When possible, the tension on the main bed should be as loose as it will allow, if stuffing the pockets is planned. Without wadding, the face can have a crumpled look with a smooth back.
A small test with a 15 stitch wide pocket

Going further in automating the repeat: this card portion includes the sealing rows (1 and 2): extend repetitions of rows 3 and 4 until the length of the desired pocket is reached for your DIY repeat. The ribber is set to slip from right to left and knit from left to right, the main carriage to knit from left to right, and to slip from right to left (opposite part buttons). With carriages at right insert the card, lock on row 1. KC <–, knit 1 row in rib from right to left, release card (or mylar), and continue knitting to the desired length. Make certain there is an even number of rows between each pair of sealing rows in your own design. It takes pairs of carriage passes to complete each circular round. To use the repeat below as a continuing pattern, one row in its height would need to be removed or added. A test  of the repeat

Double jacquard 3/ single bed multi color slip

Double jacquard knitting allows one to design and knit multiple color patterns without the worry of floats. The color changer (standard machines hold a limit is of 4 colors at any one time) and the ribber is required. The ribber knits the floats into the second layer of fabric on the ribber side, resulting in the term double knit. Often the main bed is set to slip throughout. Slipped (or first-row tuck) stitches become elongated until nonselected stitches knit off. The more the colors in any one row, the more all the stitches on the front face of the fabric must stretch in order to accommodate the number of colors laid behind in the backing fabric. The elongated stitches may allow for the other colors to be seen, and this is often referred to as “grin/bleed-through”. Different ribber settings may help with some of the elongation (depending on separation method) and grin through issues. The same principles used for DBJ separations apply to single bed multiple color slip stitch, and creating the initial swatches single bed can serve as a test for the DBJ pattern separation. In the series below some of the potential issues become obvious

the design repeat

The simplest color separation expands each row of the design to X times its original length based on the number of colors per row; in this case, 3 design rows expand to 6. In addition, in order to knit the fabric, the elongation function (X2) must be used, and each color for each design row will be knit twice, with color changes every 2 rows. This is necessary if the color changer is to be used since it takes 2 passes of the knit carriage to travel away from and back to it in order to pick up the next color. The result is a very elongated design. It is possible to knit the same motif without elongation, but then the yarn needs to be cut and changed on the appropriate side and each row, creating side edges not suitable for garments. One can separate any design with this method, and the motif may even have an odd number of rows. The sequence below is for the expansion of the first 2 motif rows

The graph below shows the motif in repeat, the next column the color separation, with expanded rows, and in the third, the black indicates the knit stitches (black squares on mylar, punched holes in card)

Testing the design single bed slip stitch: the resulting fabric is dense, with lots of floats, and narrow in final width, with little if any stretch. In the knit swatch: elongation is marked, would remain so even if the fabric were knit double bed and settings on ribber to reduce elongation were used

There are 2 other options for separating colors that deal with the problem of elongation, but they do not work on every design. The separation on the left is set up in sequential 2 two row units. In a 3 color pattern, each row of the design expands into 6. The selection row is made toward the color changer. The separation on the right also retains the knit scale. In using either one must often be willing to adapt and edit the original design motif. The total number of rows is the same as the previous method, but the sequence for color one is split as seen in numbers beside the color column in the chart. The selection row is made away from the color changer, knitting a single row in the pattern for color 1. In these separation methods, the motif must have an even number of rows

The respective resulting swatches: the elongation problem is solved, but the repeat is off in the upper third of the design. Some separation programs are able to scan through your design and locate the problem areas, even shuffle the order in which the colors are knit in order to allow the separation to work, but manual solutions may be quite time consuming or at times not possible

A redesign: one method to avoid pattern shift problems and ensure success is to use units in the design that are 2 stitches high, as seen in the motif and its separation below.

In knitting, the selection row is made toward the color changer. In rows where color 3 is not represented, only the first and last needles are selected, and manually pushed back to the B position. Eliminating end needle selection can cause problems at the outer edge of other colors, eliminating blank rows from graph and knitting would require much more attention to where in repeat one is actually working, and lead to possible frequent mistakes in color sequence.

Double Jacquard 2

The Passap Handbook for the Deco by Bernadette A Ernakovich was an excellent guide to exploring the qualities of changing lock settings on the hand, feel, look, and in shape alterations on the original design, a simple triangle, when using them. In knitting any fabric, distinctions need to be made between what is doable vs practical. Japanese machines are less tolerant than Passap for repeated functions on the same needles, and the numbers of stitches and of rows, if attempting to duplicate textures, often need to be adjusted or reduced. Some very interesting fabrics may be achieved by hand changing ribber carriage settings on the Brother KM, which are made far easier on the E 6000 because of its collection of lock settings in conjunction with arrow keys on the back bed. I amended the “Passap” triangle to the smaller repeat below

This document DBJtest includes directions on using the design repeat as is, or separated for DBJ work by 2 different methods for both punchcard and electronics: color separations. Swatch photos are below, this type of exercise shows how the resulting fabric may share a single design, but is changed sometimes surprisingly by changes in ribber settings

Double jacquard 1

Because of recent changes in my life, I may be in the position of attempting to explain to some new knitters how DBJ “works”, and to offer them some suggestions on managing the making of it. Since the machine I will be using is a Brother electronic specifically, I am gathering notes that are pertinent to that brand. I thought I would share some of my working notes here. The set below was gathered more than 2 decades ago, so I cannot add a specific bibliography, and information that may be gleaned from manuals is not included. This is the start of an ongoing series, including some DBJ rules for 2 color work, Brother machines, some adjustments need be made for more colors or for use on other KM brands

knit slowly, watching edge stitches to ensure that they are knitting off properly. If they are not, hang the side weights on the work, and move them up every 20-30 rows

clear the end stitches on every row, be especially watchful in wide pieces, failure to do so may cause mis-patterning or dropped stitches at edges

listen for the click when changing colors. On brother machines the carriage must be taken far enough to the left for the click to occur, lining up the connecting plate for the yarn change. If the color is changed without going far enough, you may either knit with the same yarn or no yarn

thread all four yarn holders, then if the wrong button is pressed you will only knit a row in the wrong color instead of dropping your work to the floor

check your yarn change before you knit each row for the correct color or the possibility of 2 yarns traveling together

weigh the work evenly

be certain selection row is in the correct direction (with pattern locked on punchcard), or you may end up with stripes rather than a pattern design

if you need to stop work, leave with carriage on right, it makes it easier to identify which color was last used in your sequence

do not use fully fashioned decreases as this affects the pattern near the edge stitches

reduce weights to correspond tho the number of needles in use when decreasing

work multiple decreases ie at underarms with carriage on the right, this way both sides may be shaped at once using the main yarn on right, the next color on left, thus avoiding long floats

if the design is not an all-over one, continue in Jacquard for the remainder of fabric, using a repeat that has 2 rows marked/punched, 2 rows un marked/punched throughout

ribs in single strands of garment yarn may be too soft or wide, for 1X1 ribs try adding an extra strand of yarn. When the rib is completed, pick up the heel of the adjacent stitches to fill in empty needles, and knit 2 circular rows before continuing in jacquard

2X2 ribs are better suited to single strands of yarn; at the top of the rib bring the empty needles into work, rack to the left and knit 2 circular rows, rack to the right and continue in jacquard

full needle ribs are usually wider than jacquard, as an alternative, the piece could be started on waste knitting, and rehung on fewer stitches, then, in turn, knitting the rib

the lili buttons represent every other needle set up, so an even number of needles is required; the needle position indicators on the ribber tape and the corresponding space between them help track pairs/ even numbers of needles in work

racking handle on P: the knit and purl needles are point to point, directly opposite each other, on H the purl needles are halfway between each pair of needles on the opposite bed, and the latter is most often the basic needle arrangement for double jacquard; check needle alignment before knitting planned fabric to avoid needle damage, etc

vertical striper backing on brother kms is possible but needs a bit of added manipulation and its own specific directions for needle set up

for thicker fabrics, the needle arrangement on ribber may be for 1X1 rib, 1X3, or other configuration, pitch on P. The larger the number of needles on either bed, the closer the tension on that bed to the tension suitable for that yarn in plain stocking stitch. In this instance, the ribber tension is tightened up by one or 2 numbers. If the ribber needles are in every group, ie. 2X2, 4X4, 4X2, etc, then the lili setting may be used. This sometimes helps if the effect on the knit side tends to show noticeable vertical lines along the sides/length of the stitches created on the ribber.

arrange needles to give a neat join at seams, plying yarns may again be required

racking cast on may be used, avoiding transfers between beds after every needle cast on

https://www.youtube.com/watch?v=u90_iobGu-0 shows one method of working and illustrates needle arrangement well and transitions to main bed knitting

I personally never do 3 circular rows after the first cast-on row: it will produce floats on one side of the rib, which may be noticeable in your final fabric on one of the 2 sides.

the alternative: with the same needle set up:

to close holes rack the beds one full turn, knit 2 rows, rack back again, and arrange for desired fabric

Working out the kinks in my drop stitch lace saga

Still geared up for accessories, I felt compelled to come up with an edging: the following is an end stitch release knit. Prior to binding off the “tape” end stitches are transferred to the knitting bed, and then they and the remaining stitches are bound off. The transferred stitches do not drop and create a long stitch double knit segment. I am still working with the white acrylic
bound off and before release with the release starting after release
after pressing: flat, edge stitches too short attached to back bed before knitting pattern  (purl side)knit side alpaca and silk swatch, surprise: this baby knits up/steams fairly flat! The most regular dropped stitches happened when the stitch ditcher was used at least as frequently as every 4 rows, the lock was too hard to push with it resting on the knitting bed before each pass. I thought I might break down and use a built-in technique and my color changer to drop stitches: Technique 256 here I come, and figlet! this is a completely different fabric and there is one row of loops formed for every 4 passes of the lock I now get why some people call drop stitch with this technique mock garter stitch, but that is so not what I was going for, so back to the drawing board for me! I have an idea….
if the repeat is twice as long, and 2 of the 4 rows are knit without yarn, then loops created on the first 2 rows should in theory be dropped. Tech 130 in essence doubles repeat length. Using it and the same back bed pusher arrangement and settings as tech 256 the fabric is much more like the original, but tension now needs to be adjusted, denser knit stitches are now too loose… time for a very long break! you can’t always get what you want, do you sometimes get what you need? Curses! triple the number of stitches and tension problems occur, stitches don’t want to drop in specific areas of knit, now using a combination of empty lock and occasional hand ditching, different yarn, totally different look fabric than on the first sample: here it is on the machine
this shows why any lace needs blocking. Finishing on the Brother: bottom and top of ruffle rehung and cast off around 2 gate-pegs for length matching width of “pleats”; piece and “ruffles” also rehung for the same type of join after 1 row of knitting through both layers. The finished piece measuring 17X60 inches after partial blocking.  A different stitch pattern (E6000 1130) in the white acrylic color striping in the alpaca/silk blend, requiring dealing with yarn ends at color changer side. I had an interesting experience while knitting the one above of both locks jamming in the color changer. So many ways to have fun! and … I still want some bubbles!
A thicker yarn, larger tension difference between the locks, a bit more bubble on the knit side, but  too  much effort to knit

Knit bubbles and “stitch ditchers/dumpers”

I encountered a photo of a commercial sweater not too long ago while knit surfing the web

and a bubble blanket available at Nordstrom’s during 2012

I had already been considering laces other than transfer ones for yarns that have been too crotchety to knit in that particular technique, and my Passap has been knitting idol for far too long.  The fabric above seems to alter between purl and knit sequences that would require transferring all stitches to the opposite bed for every other pattern sequence: out of my range of patience and time. The number of fabrics involving “lace” produced using the ribber involves a series of names with sometimes variations simply being specific to the technique performed on a particular brand, though possible on all. On the list: drive lace, pick rib, summer fair isle, drop stitch lace, etc. The above commercially produced knits seemed to be good candidates for drop stitch lace.

Since I recently posted on knitting long loops/stitches single bed, it seems natural to follow up that post as well with creating long stitches using the ribber and using automatic patterning as well. The following photo is familiar to most Brother users:

In this instance the fabric is produced as a hand technique, requiring racking and row counting. The process is easier if all stitches are transferred to ribber in Japanese KMs or back bed on Passap, and long stitches are then created by selected stitches knitting on the opposing bed, and in turn, being dropped. Punching a card, drawing on mylar, or downloading to machines makes it possible to do so in a pattern much more easily.

Punchcard books have several useable examples for such patterns. Two methods of release are used. One is end release, where the pattern is knit until the piece is completed, and stitches are dropped then. This works in friendly yarns and continuous repeats uninterrupted by rows of stocking stitch. If the design is interrupted, then the regular dropping of stitches whether at the end of the repeat or intermittently throughout is either required or preferable, depending on the design.

As for dropping those loops that will form the long stitches, one can do so “manually” with improvised tools. For more “automatic” dropping of stitches using knit carriage in Brother patterning, one may punch a card or draw a mylar with a method akin to the color separation that will allow for a pass of the KH carriage across the knit with no yarn in the feeder, “color 2” is actually “no yarn/empty” while establishing the proper needle selection on its return. Studio selects and knits in the same row, so needle selection disruption is not an issue, and in Passap techniques are built into the console that allows for “free/no yarn” passes. Both instances involve extra “knit” rows per item. Other alternative tools may be used that help the stitch ditching process. Studio brand had their P carriage and Brother their own “D slider” for the bulky KM.

The Studio P carriage pulls needles on the main bed from B to C position going from right to left, then returning them back to B position going from left to right. On the ribber, it may be used to bring the needles up to C position for “safe knitting. (Studio needle positions are A, B, C, D, while Brother skipped the letter C, continuing with D and E). A video from Susan Guagliumi shows a later model than the one pictured below, used as well to bring needles out after hand techniques as opposed to pulling them out by hand or to insure thicker yarn knitting.

The Brother Bulky KR 260 D slider only moves in one direction, from left to right, completing the in and out needle position operation in one pass. End needle selection needs to be canceled. It is not usable on ribbers. After operating it from left to right, it is simply lifted off.  The knit carriage position while the transfers are occurring may vary depending on personal preference and whether the yarn changer is in use or not.

Directions on altering the studio tool for use on Brother machines

Passap’s need was answered by an Australian woman: Faye Butcher,  who developed the item shown below. Such tools were often discussed in seminars and publications of the time, in conjunction with pile or “carpet” knitting, so “P” for such knitting in Studio, and “carpet stitch tool” for Passap, seen below

rear view

in use on the front rail

If patterning for long stitches occurs on the front bed, the Passap tool sits on the rail where you see it in the photo, it will release all stitches from needles in its path. Often directions for using it recommend its use for 2 passes with locks on right. Passap preselects pushers for the next row of knitting as Brother preselects needles, pushers are below the rail, so in theory, they should be unaffected bypasses of its travels. Once things are up, going, and “working” I have found it possible to align the tool as seen in the photo ahead of the next lock pass, so on the right of the lock from left to right, to its left from right to left, a bit of pressure will keep it in its place, and stitches are released each pass of the lock. This may result in having to operate the lock with one hand. There is also an optimum speed: if the movement is not smooth and regular and needles are jostled, pusher selection may be altered in response, thus resulting in a patterning “mistake” on the next row. Challenging yarns may make this method impossible.

Some samples follow: the yarn used was acrylic, I attempted to press it on swatch completion, and this flattened the fabric considerably. Of note: the disparity in width between the stockinette portions of the swatches, and the dropped stitch segments

too open

a bit closer, much more so before steaming

a “mistake” that may lead to a future accessory, with some revising and planning

I am using Stitch Painter to plot out my repeats, exporting files as .cut files, using wincrea to import them, and downloading to the console with a cable purchased from England. I replaced an ill tower dell with a 64-bit dell laptop half its age, and am now running Windows XP instead of 98! My leaps into the present technologies/software are made using apple products. Technique 129 will work, color may need to be reversed using the alter loop, or within wincrea depending on how the pattern is drawn in the original graph, but that is a topic for another day (see April 2011 post: a bit on Passap for some information on Tech129). Back lock on N throughout, front lock on LX (slip/part on the main bed for Japanese KMs). Single bed slip and tuck stitches may also produce “bubbles” of a different quality.

Coincidentally the 10th-anniversary issue of Knitty has just been released, arriving in my virtual mailbox this AM. There are 2 patterns in the issue that may be of interest, one is tin roof, the other employs ribbed/bobble/bubble for hand knitters. Another hand knit version by Kieran Foley may be found here

To block or not to block

Pattern repeats are sorted out, out of work needles correct positions critical, many false starts, then onto yarn crankiness. Two “shawls” are now knit, approximately 16 inches by 64 inches, one in off-white cashmere, the other in over spun wool. They are large enough to drape around shoulders, lightweight enough to wrap for warmth as scarves. Both required washing to remove sizing, are now very different in body and touch. My favorite way to “block” laundered items is air drying on a wool rug after a couple of spin cycles in the washer. I use pressing/steaming if appropriate to fiber, do have blocking wires,  but they have only ever seen daylight as substitutes if I “lose” ribber cast on comb wires. Next in this family will be a shot at knitting this item with a thin ribbon. Here is the completed drying twosome with their purl side public face. The Knit side is interesting as well, duplicating the hand technique swatch exactly. Yarn weights used are pushing boundaries for KM, knitting is extremely slow after design/yarn problems are all sorted out. Though this online post follows camera documentation that began yesterday, the actual process has occurred over the past 2 weeks.
