Description

Preparation method of wrinkling fabric Technical Field The invention relates to the technical field of textile processing, in particular to a preparation method of a wrinkling fabric. Background The feel, appearance and color of garments are central elements that account for the nature and style attributes of the product. Wherein, the appearance effect of the fabric is not only dependent on the conception and arrangement of style design, but also is inseparable from the inherent characteristics of the used fiber. Taking polyester fiber as an example, the natural crease resistance of the polyester fiber enables the fabric containing polyester components to be limited in morphological expression, and natural and vivid crease texture unique to natural fibers is difficult to be presented.

The process is complex, and is difficult to meet the requirement of mass production. Therefore, how to optimize the wrinkling processing method of the polyester fabric, so that the wrinkling processing method is suitable for the requirement of mass production and meets the environmental protection requirement, and the wrinkling processing method becomes a technical problem to be solved urgently. Disclosure of Invention Aiming at the technical problems, the invention provides a preparation method of a wrinkling fabric which is uniform in wrinkling and environment-friendly. The technical scheme of the invention is as follows: the preparation method of the wrinkling fabric comprises the following steps: s1, feeding; putting the fabric with the terylene content of more than 60 percent into a treatment cylinder, wherein the volume of the fabric is matched with the volume of the cylinder; S2, wrinkling; Carrying out high-temperature high-pressure accumulation treatment on the fabric in a treatment cylinder; The temperature in the treatment cylinder is controlled to be gradually increased to the highest temperature of 130-135 ℃ in a step mode, the temperature increasing step is not less than 5 levels, the temperature increasing rate of each step is not completely consistent, and the temperature is kept for 15-60 minutes under the highest temperature condition after the temperature increasing is finished; S3, cooling; And (3) cooling the fabric prepared in the step S2 to prepare the wrinkled fabric with the wrinkled feeling.
