As a result, the fabric has a higher density, is thicker, has better gloss, has a softer feel, and has better elasticity than the plain weave. Under the same conditions of yarn density and thickness, its wear resistance and fastness are not as good as plain weave fabric.

Plain cloth, because The warp and weft yarns are interlaced every other one, so there are many interlacing points and the number of yarn bucklings is high, making the fabric strong, wear-resistant, and hard to the touch, but less elastic and less lustrous; secondly, the appearance of the front and back of the plain weave cloth The effect is the same, the surface is flat and the pattern is monotonous.
