Unraveling the Secrets of the 2/1 Twill Weave Structure

Advantages of Twill weave fabrics

Because of its diagonal structure, twill is flexible, though it is heavy and generally drapes well. It is considered as a strong and durable weave.

Stains on twill weave fabrics are less noticeable. Also, they crease less than plain weave fabrics. Twill fabric is more durable and pliable than plain weave or satin weave fabrics.

Because of their versatility and durability, twill fabrics are used for a lot of purposes – for general and work clothing, upholstery, bed and bath linen.

Weave Sample: 2/1 Twill

In twill weaves, the weft is staggered to the right or the left, creating a diagonal effect. In 2/1 twill the weft goes under two warp threads, then over one, creating a warp-faced twill.

The 3 Basic Weave Structures

So I am not going to go over EVERY weave structure, but I am going to go over the basic three that every weaver should know!

These structures can actually play a big part in creating the basis for other weave structures that you will come across.

The basic three weave structures are plain weave, twill, and satin.

First, though, what do I mean by weaving structure?

The weaving structure is determined by how the warp and weft interact with each other. These different structures determine a lot of different aspects of the fabric including: how well it drapes, it’s strength, and the way it reflects light.

Beyond these main three patterns are many others that are built off of them. Think overshot, double weave, woven pile, manipulated laces and more.

Usually referred to as samite (or sometimes samitum).

In this sample I tested several styles of samite. From the bottom up, we have:

  • Plain (unfigured) samite
  • Duochrome figured samite (1-2-2-1 weft order)
  • Duochrome figured samite (1-2-1-2 weft order)
  • Monochrome figured samite (1-2-2-1 weft order)
  • Monochrome figured samite (1-2-1-2 weft order)
