The mysterious KH-940 weave knit

One of the knitting techniques that was omitted from the list we experimented with uptil now (the skip, patent, nordic, lace and jacquard) was the weave stitch. Experimenting a bit with the weave knit was giving puzzling results. Most of the time this is frustrating, because it means this is going to cost time. On the other hand, if something costs time, it also means that there is something to discover…

I discovered that moving around at either side of the knitting on the knitting machine caused a needle count error, this is fixed now in the software:

(This still is the very basic software. No fancy stuff for an image moving in the Processing sketch when knitting a tour. If the image is too big the underside can even be out of sight. I am wondering about the possibility of having a choice between the different stitches, then give a simple analysis of the image, if this is the right image for this stitch…-possibility to get the inverse -negative – image or the mirror image. Even have an indication if the distribution of the pixels is fit for this stitch.)

The weave stitch is using the entrance of the slider, without being inserted in the first or second thread opening in the middle of the slider:

The base thread (in the middle opening) has to be very thin and the tension is set to 1-2. The second thread has to be thicker yarn.

Because of the tension setting the produced knitted surface is about half of the image knitted: so starting with the normal dimensions

you get this knitting:

This is the back of the knitting, that is why the letters in the image are mirrored. For this experiment, we used the MPPT graph again. Apperently, for the weave stitch the pattern of the filling is important. This has to be prepared in Photoshop using the (self defined) preset brushes and patterns.

Then the next step is to enlarge the image height. The graph has to be stretched in the image, to have it normally scaled in the knitting. You cannot use “free transform”, because this would destroy the fill pattern of the surface (although this sometimes gives ideas too). The rescaling has to be done by hand,

Also we varied the fill pattern of the surface. You already see that it is difficult now to keep the graph in the right shape.

This resulted in knitted weave images were not convincing, the graph appears, but only dim, the weave pattern inside the thin thread is not crisp: See here back (left) and front (right) side:

weave1

During knitting the thick yarn was changed three time, to see which would work best. Vertically up the thicker yarn was yellow, middle we used two middle thickness yarns – yellow and light pink- and below the thick plastic pink yarn also used for the pollution scarf.

Here the thicker yellow yarn and the double threads is displayed.

testing further:

Again changing the fill and also making the graph more clear, taking the brush of example 426 from Stitch World Pattern book: x00x00x.

Also changing the basic thin wire to even thinner (shining blue very thin yarn).

Starting of with the thick plastic pink yarn we wondered about the fact that the knitter was not at all complaining about the thickness of the pink plastic yarn, while the tension was set to 1. Normally for this yarn the tension has to be 9-10. Ok then try even thicker yarn, the bright yellow which we also used for the presentation “Yellow Things”. This was knitted on a knitter with much bigger needles and distance between the needles.

There was no problem knitting this thicker yarn and the image got out very clear now:

2014-10-19 10.33.04  front 2014-10-19 10.28.32 back (on the knitter)

This is the fron side of the image, where the thicker yarn is beautifully overlayered by a mesh of the blue thinny yarn.

Details:

Details of the fill, the mesh formed by the thin blue yarn, the way the graph is showing in the texture. You can see how the thick thread is catched inside the mesh of the knitting.

This weave pattern begs for more experiments!

Finishing with the cones of the yarn side by side:

When i looked back i realized the maybe it is not really the thickness but the relative textures of the threads…more experiments are needed.

Added:

Weaving the same image with a very thin plastic fiber. The ordinary yellow wool seems to be caught inside an invisible plastic mesh:

some details where the plastic mesh can be seen, and the side with the arched wires.
