Abstract

The invention relates to a method for preparing a polyester crinkle chiffon fabric. The method includes the steps that warp yarns are prepared from polyester silk-like silk, and after weft yarns are prepared by combining semi-dull DT yarns with hemp yarns, interweaving is carried out to obtain a plain weave and dyeing is carried out to obtain the polyester crinkle chiffon fabric; the preparation process of the semi-dull DT yarns includes the steps that after a PET melt is extruded from trilobal spinneret holes in a spinneret plate, cross air blowing is carried out for cooling, and the semi-dull DT yarns are prepared according to a POY-DT process; before dyeing is carried out, the breaking strength of the semi-dull DT yarns is larger than or equal to 3.0cN / dtex, and the elongation at breakis 40.0+ / -10.0%; and after dyeing is carried out, the semi-dull DT yarns have a three-dimensional crimp shape with a crimp shrinkage rate of 25-28%, the crimp stability is 77-81%, the shrinkage elongation is 65-68%, and the crimp shrinkage elastic recovery rate is 74-79%. The crinkle effect of the polyester crinkle chiffon fabric is stable and lasting, and the crinkle is not prone to being affected by the environment and destroyed by the way of use.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a method for preparing crepe fabrics. Background technique [0002] Crepe crepe is generally made into a plain weave structure, and the difference in twist in the radial direction and weft direction is designed. After dyeing and shrinkage, the warp and weft yarns are twisted to form a crepe-like cloth surface, and the crepe crepe fabric has a natural stretch. Effect. It can be seen from the processing technology that in order to obtain the style of crepe, one of the warp and weft yarns needs to be twisted strongly (to make the twist of the yarn reach 1800 twists / meter), so that it has a high twist, but the high twist will cause the fiber to twist. Damage affects quality. [0003] In addition, the crepe feeling of crepe made of strongly twisted yarn is destroyed by gravity when it is hung. The specific reason is that the uneven shape and stretching state caused by twisting...
