Abstract

The invention relates to a preparation method of an elastic chiffon fabric. The elastic snow is prepared by using low-elastic polyester fiber as the raw material for warp warp, using low-elastic polyester fiber and cotton fiber as the raw material for crepe weft, interwoven into a plain weave, and then performing relaxation heat treatment. Spinning fabrics; the preparation process of all low-elastic polyester fibers is: according to the FDY process, a circular side-by-side composite is prepared from PET (intrinsic viscosity: 0.60-0.65dL / g) and PBT (intrinsic viscosity: 1.00-1.20dL / g). In the process of fiber production, the spinneret holes on the spinneret are trilobal, and the ring blowing is used for cooling, and the arrangement of the trilobal spinneret holes is controlled to meet certain conditions, so as to obtain low-elasticity polyester fibers; The elastic recovery rate of the chiffon fabric is 99.5% to 99.9% in the warp direction, 99.5% to 99.9% in the weft direction, 18.7% to 23.3% in the warp direction, and 24.9% in the weft direction. ~28.1%.

Description

Technical field [0001] The present invention belongs to the technical field of textile fabric, and is related to the preparation method of elastic chiffon fabrics. Background technique [0002] Chiffon fabric is a very thin chemical fiber fabric, suitable for women's summer dress, touching a little small hair; generally be divided into silk chiffon and simulation silk chiffon, chiffon made of different raw materials The difference in fabrics is very different. The most common chiffon fabric is made of polyester wire, because the chiffon manufactured by polyester wire made of chiffon, wear-resistant and other fiber materials blended to impart more performance If spandex is blended, the chiffon fabric has a certain elasticity. When using spandex woven elastic chiffon, the spandex can cause molecular chains in a spandex molecular chain in a spandex molecular chain in the thermal treatment and washing, intensity and elasticity. The process of returning; in the woven, pre-treatment, p...
