Yarn-dyed seersucker
(1) Basic style characteristics (dyed weaving) seersucker is a plain weave fabric woven with two warp yarns (bubble warp and ground warp) with large tension differences arranged alternately. The surface of the fabric appears as vertical strips formed by regular, bubble-like wavy wrinkles. The bubbles are raised and give a sense of standing. The bubble shape of seersucker is “clear, uniform and stable”. The bubble warp tension is small and the ground warp tension is large. The degree of difference is large. Double warp beams should be used for weaving. (2) The foaming principle of seersucker The foaming principle of seersucker is mainly due to the different let-off amount of the let-off mechanism during the weaving process. The bubble let-off amount is large and the tension is small, while the ground let-off amount is small and the tension is high. The difference in tension of the foamed warp causes differences in the tightness of the fabric after the foamed warp and weft yarns are interlaced, and the shrinkage rate of the foamed warp is different. When beating up, the looser bubbles become wavy and wrinkled to form bubbles. (3) Seersucker fabric design 1. The let-off ratio of the bubble and ground warp is too small, and the bubbles are not only small, but also of different sizes; the fiber feed ratio of the bubble and ground warp is too large, and the bubbles are not straight and uneven, and The cloth surface has obvious pat marks, many weaving defects, and weaving is difficult.
