some knownledge of Chinaese fabric-Twill
Silk fabric with a twill texture, marked by diagonal lines. It's light and soft. It is often used today for mounting pictures. The so-called twill tissue refers to the tissue where the warp and weft are joined into oblique lines. The warp and weft interlacing points of twill organization are less, so the durability is slightly lower, glossiness and elasticity are higher.
According to raw materials, ghatpot silk can be divided into pure mulberry silk fabric, synthetic fabric and interwoven products. The ground texture of the damask fabric is a kind of textured twill fabric or textured twill fabric, which is mainly mixed with other tissues. The common kinds of damask fabric are jacquard damask, Canton damask, mixed damask and cotton damask.
Twill weave also has the concept of a "float cord", which refers to a warp/weft yarn floating on top of adjacent weft/warp yarns. Damask was produced before the han dynasty and flourished in the tang and song dynasties.
There are two main kinds. One is the flower, the organization of the circulation number is the same and the twill direction is opposite, called different direction ghantpot, if the organization of the right, then the organization of the flower for the left. The fabric is very flat due to the same tightness between the flower part and the ground part. The other is the flower, tissue oblique to the same but the organization cycle number is different, called the same direction ghatpot. The flower part is right-oblique and the ground part is right-oblique. The fabric floor is tight but the flower part is tight, the yarn produces the displacement, and the pattern has the concave and convex effect.
