Plain and twill are different forms of textile:
Plain weave: The warp and weft yarns of the plain weave are interwoven with the rules of the fabric. That is, weft yarn every single yarn is staggered, so the most interwoven point, yarn buckling point, so that the fabric fastness, wear-resistant, stiff, flat, but less flexibility, gloss general, plain fabric density can not be too high, more frivolous,good abrasion resistance and good permeability.
Twill Fabric: A complete organization must have at least three warp and three weft yarns interwoven, with only one weft-tissue point on each warp weft. The surface of the fabric is formed by the continuous tissue point. The twill structure is the appearance effect of the twill on the surface of the fabric by the floating line or the weft-floating line. Twill fabric of warp and weft yarn is less than plain weave, is a small amount of latitude between warp and weft yarn, yarn can be arranged in a dense, so that the fabric is relatively dense and thick.
Twill softer than plain fabric, good elasticity. However, because of the long length of twill fabrics, in the warp and weft yarn thickness, the same density, wear resistance, fastness is inferior to plain weave. The cloth has obvious oblique grain, feel, luster and good elasticity.
How to distinguish between tabby and twill?
It is easy to recognize through the naked eye. Plain Weave: There is no positive or negative difference in actual use.
1.Single-sided twill: such as twill, single veil khaki, positive lines clear, the opposite is ambiguous.
2.Double-sided twill: such as gabardine, double-sided Khaki, Serge and so on, positive and negative lines are basically the same, but oblique opposite. The front line of the single yarn fabric is tilted from left to right and the lines of the half-thread fabric or the entire fabric are tilted from left to right.
