Woven Moiré Samples

May 29, 2018

I read Verda Elliott’s interesting article, “Woven Moiré: a Fabric that is About a Fabric,” when it was first published in Weaver’s magazine issue #20 in 1993.  I have been curious about woven moiré ever since I read this article, and I finally decided to give it a try.  Sadly, Verda passed away in 2009 but her inspiring work lives on.

In this article, Verda describes how one of the ways commercial moiré fabrics are made is by physically pressing a moiré pattern into the face of the fabric with rollers that have a moiré pattern engraved on them using pressure and heat.  But Verda wanted to achieve a moiré effect in a woven structure so she used a divided draft, superposing two twills.  I think she used the word “superpose” rather than “superimpose” because it’s a more scientific term.  I followed Verda’s instructions and wove a few moiré samples using her drafts from the article and then designed my own drafts and wove some more samples.  In this post I’ll be sharing my moiré experience with photos, drafts and notes.

One of Verda’s drafts is for a moiré evening bag that I used to weave Sample #1 below.  The photo shows the mostly weft-faced front and the mostly warp-faced back.  Verda’s draft has a straight and an undulating twill threaded alternately – one twill on odd warp ends and the other one on even warp ends, and it has alternate treadling as well.  To weave the fabric for her evening bag she used shiny rayon yarns that work really well for creating a moiré effect.  I used yarns that are not as shiny as rayon – white 10/2 pearl cotton for the warp at 28 epi and blue and tan 5/2 pearl cotton for the weft.  The finished cloth is fairly stable and somewhat thick with areas of very long floats among areas of firm plain weave.

Sample #2 below is my own design.  This time I used white 20/2 rayon for the warp at 40 epi and purple and orange 5/2 pearl cotton for the weft.  The floats are not as long as in Sample #1, but still long:  9 in the front and 17 in the back.  But surprisingly the finished cloth is very stable.

Below are different views of a partial draft for Sample #2.  I  like using straight and undulating twills, but Verda notes that you can also use other types of twills like point twills.  In this draft each twill uses its own threading, treadling, and tie-up with a total number of 15 shafts and 15 treadles.  Verda recommends an odd number of shafts because it produces a better moiré effect.  Most moiré drafts are very long and this draft is also too long to post a full repeat of it here.  I thought of using Fiberworks’ “interleave” feature to generate the draft, but it doesn’t seem to work with an odd number of shafts and treadles.  So I did it manually with the help of the “copy” and “paste” features.

Next are two samples I wove from another one of Verda’s drafts.  Samples #3A and 3B are front and back of the same sample using alternating black and white 20/2 cotton for the warp, and alternating purple and tan 20/2 cotton for the weft.  The sett is 40 epi.  In this sample, I think the mostly weft-faced front and the mostly warp-faced back are both interesting.

Sample #4 below uses the same threading as Sample #3A/B but the 20/2 cotton warp is all white, the 20/2 cotton weft is all black, and the sett is closer at 54 epi.  There is something very different about this sample – both twills are woven simultaneously by using 2 treadles at the same time rather than alternate treadling.  The photo shows only one side, but both front and back are mostly warp-faced and look similar.

I was curious about the French word moiré, so I looked it up online and found several meanings.  From the ones referring to moiré textiles I really like “watered silk” and “cloth, especially silk, with a pattern on the surface that looks similar to waves on water.”  In general, moiré is more commonly known as “a pattern seen when 2 geometrical patterns such as grids are visually superimposed.”  I have seen photos of such a moiré effect when 2 screens are superimposed and here’s one I captured with my camera:

That’s it for moiré!  See you next time!

UPDATE June 6, 2018:  Marilize van der Merwe sent me photos of her beautiful woven moiré work that she is kindly willing to share with everyone.  Below are a few of the photos, thank you Marilize!

In the photo below Marilize used white mercerized 20/2 cotton for the warp and beige and green Nr. 8 crochet yarn for the weft and the finished fabric is for a slightly puffed head board for her guest room:

In the next photo Marilize used white 20/2 mercerized cotton for the warp and white and gold novelty crochet acrylic yarn Nr. 8 for the weft and the finished fabric is for lined evening bags:

In the last photo below Marilize used white 20/2 mercerized cotton for the warp and 4-ply purple knitting yarn for the weft and the finished fabric is for decorative fashion blanket throws for the bed with a plain chenille lining on the back to cover the long floats in the warp:
