Embodiment 1

[0018] A kind of preparation method of regenerated cotton, comprises the following steps:

[0019] a. Material selection: First, vibrate and screen the cloth ends, scraps, waste silk and yarn ends to remove large particles of solid impurities, and then classify the cloth ends, cloth scraps, waste silk and yarn ends according to their physical properties. Obtain a variety of cotton fabric scraps;

[0020] b. Pretreatment: Alkaline washing, primary water washing, hydrogen peroxide bleaching and secondary water washing are carried out on the obtained various cotton fabrics, and then various cotton fabrics are mixed and dehydrated and dried, and finally the cotton fabrics are removed by cyclone dust removal. Light sundries to obtain a pure white fabric with a moisture content of 1%; among them, alkali washing treatment, primary washing treatment, hydrogen peroxide bleaching treatment and secondary washing treatment are all carried out in a mixing tank, and the alkaline washing tre...

Abstract

The invention discloses a preparation method of regenerated cotton. The method comprises the following steps: a, sorting: firstly performing vibratory screening treatment on leftover, scrap, waste silk and yarn ends to obtain various cotton textile scraps; b, pretreating: performing alkaline cleaning, primary washing, hydrogen peroxide bleaching and secondary washing treatment on the obtained various cotton textile scraps respectively to obtain a pure white fabric stock with moisture content of being smaller than 1 percent; c, reprocessing: cutting the pure white fabric stock into fabrics with a physical character of being smaller than 1,200 mm, then reducing the fabrics into wool cotton, next loosening the wool cotton, and finally fluffing the wool cotton to form the regenerated cotton; d, packing: collecting fibers with length of 26-28 mm in the regenerated cotton, and packing the collected fibers to obtain the qualified regenerated cotton. According to the method, the waste textiles such as the leftover, the cloth scrap, the waste silk and the yarn ends are recovered and recycled.

Description

technical field [0001] The invention belongs to the technical field of regenerated cotton production, in particular to a method for preparing regenerated cotton. Background technique [0002] With the shortage of raw material resources and the need to protect the environment, more and more attention has been paid to the recycling of waste textiles. In recent years, with the development of science and technology, the manufacturing level of machinery and equipment supporting the recycling and reuse of waste textiles has also been continuously improved, and the types of waste textiles that can be recycled and reused are also increasing. In developed countries, the recycling rate of textiles is very high, and the technology of how to use these waste materials to successfully develop new products is becoming more and more mature. In the 1990s, Western European countries began to explore the recycling technology of nylon. A new technology to produce high-quality coinage paper fro...
