Method for producing elastic silk-like chiffon fabric

Abstract

The invention relates to a method for producing a chiffon fabric and particularly relates to a method for producing an elastic silk-like chiffon fabric. The method comprises the following steps of: rolling up grey cloth; refining, untwisting and preshrinking; presetting; reducing the amount of alkali; dyeing; cleaning; after-finishing; and detecting, batching and packaging. The raw materials of the silk-like chiffon fabric comprise warp yarn and weft yarn, wherein the warp yarn is made of 30D superfine denier fiber, and the weft yarn is made of 30D superfine denier fiber and spandex fiber. By improving the processes of refining, untwisting and preshrinking, the fabric is uniform in folds and loose in structure, and by improving the processes of presetting, reducing the amount of alkali, dyeing and cleaning, the fabric overcomes the defects in the prior art. The obtained final product makes people who wear the clothes made of the fabric looks skinny and has good air permeability, drapability, static-electricity resistance, moisture absorptivity and wearability, and soft, full and fine handfeel, and the weight gram and the handfeel of the fabric can meet the requirements of people.

Description

technical field [0001] The invention relates to a preparation method of a chiffon fabric, in particular to a production method of a simulated silk elastic chiffon fabric. Background technique [0002] The imitation silk chiffon fabric is mainly composed of polyester fiber, because it feels good against the skin, has a natural drape shape, is not easy to fade, and is easy to take care of. Therefore, it has become the most popular fabric in spring and summer dresses in recent years. Moreover, this kind of fabric can be expressed in a variety of ways in printing and dyeing, and can be operated by various processes such as dyeing, embroidery, and bronzing, giving chiffon fabrics the characteristics of changing shapes. At present, there are many colors of fabrics on the market, among which light colors and plain colors are more popular, which have the beauty of light makeup and elegance.

AI Technical Summary

Problems solved by technology

[0003] In the raw material of the imitation silk elastic chiffon fabric of the present invention, the warp yarn adopts polyester 30D ultrafine denier fiber, and the weft yarn adopts polyester 30D ultrafine denier fiber+spandex fiber, and the untwisting process is prone to produce uneven untwisting, poor crepe effect, and alkali weight loss The effect is not easy to control and other issues;

[0004] In addition, during the dyeing process, due to the increased surface area of ​​polyester imitation silk after weight reduction, the dyeing rate is accelerated, and there are problems such as poor level dyeing, light apparent color and low color fastness during the dyeing process;

[0005] In addition, polyester fiber must be dyed at high temperature and high pressure, while spandex is not resistant to high temperature, especially under acidic or alkaline conditions with high temperature and long time, it is easy to cause brittle damage of spandex yarn, decrease in strength, and cause broken filaments.
