The appearance characteristics of twill fabrics are obvious twill lines (commonly known as lines) on the fabric surface. Khaki fabric diagonal lines require "uniform, deep, straight". The so-called "uniform" refers to the diagonal line to be equidistant; the so-called "deep" foot refers to the diagonal line to be clear; the so-called "straight" means that the diagonal lines of the yarn must be equal in length and no skew bending. The uniform and straight twill lines are the general style of twill fabrics.
There are many kinds of twill fabrics, and they can be divided into two types: left twill and right twill. According to tissue, they can be divided into single twill and double twill; they can be divided into twill, tantalum, gabardine and Khaki and other kinds.
A. middy twill
The middy twill is a 2/1 twill weave. From its surface, the front twill lines are more pronounced and the reverse is less pronounced. The texture of the twill is more compact and thick than the plain fabric, and the hand feels softer. The twill weave can be divided into three types: yarn twill, half twill and all twill, depending on the type of yarn used. According to the yarn line density can be divided into two kinds of rough twill and fine twill.
The Serge is a 2/2 twill weave, and the diagonal lines on both sides are obviously similar. The texture of the Serge is denser and thicker than the twill weave. According to the different types of yarn used, it can be divided into three kinds of yarns, half thread and full thread. The yam is left twill, the half ridge and the full ridge are right twill.
