Manufacturing technique of imitation silk bleached cloth

Abstract

The invention discloses a manufacturing technique of an imitation silk bleached cloth. The manufacturing technique comprises the steps of pre-forming, alkali peeling, dehydrating, drying, forming and whitening, and calendering; pre-forming a grey cloth under certain tension force, at preset temperature and within set time; adding in sodium hydroxide, an oligomer remover, a scouring agent and a bath softening agent after the pre-forming at a bath ratio of 1:6 to carry out alkali peeling, carrying out water scrubbing at different temperatures, reducing the temperature to normal temperature, adding in an antistatic agent, and taking the resulting cloth out of a cylinder after water scrubbing; after being dehydrated and dried, transferring the resulting cloth to a forming and whitening process; setting whitening temperature and whitening time in a forming machine, wherein a polyester whitening agent, an antistatic agent and a softening agent is used as whitening liquid; and setting calendering temperature, calendering speed, and calendering pressure in a calendering machine for calendering to obtain a finished product. The technique disclosed by the invention has the characteristics of short working procedure, low energy consumption, low pollution, consistent fabric whiteness and the like, and the produced imitation silk cloth is soft and waxy in hand feeling, natural and subdued in luster, draping and elegant in feeling, high in product grade and large in added value.

Description

technical field [0001] The invention relates to a dyeing and finishing process in the textile industry, in particular to a production process for imitating silk bleached cloth. Background technique [0002] Imitation silk cloth is processed by polyester thread instead of traditional silk. It has the texture and feel of silk. The production of imitation silk bleached cloth is to use polyester staple fiber yarn in the warp direction and polyester filament in the weft direction. The production process is as follows: scouring, dehydration, presetting, alkali reduction, whitening, dehydration, drying, and finalizing the finished product; as an alkali reduction process to improve the softness and drape of the fabric, it is to produce high-grade imitation silk products The key point is that the formula of the existing alkali reduction process cannot give polyester fiber fabrics softness, drape, moisture absorption, breathability, and antistatic effects, and cannot make silk-like fa...

[0002] Imitation silk cloth is processed by polyester thread instead of traditional silk. It has the texture and feel of silk. The production of imitation silk bleached cloth is to use polyester staple fiber yarn in the warp direction and polyester filament in the weft direction. The production process is as follows: scouring, dehydration, presetting, alkali reduction, whitening, dehydration, drying, and finalizing the finished product; as an alkali reduction process to improve the softness and drape of the fabric, it is to produce high-grade imitation silk products The key point is that the formula of the existing alkali reduction process cannot give polyester fiber fabrics softness, drape, moisture absorption, breathability, and antistatic effects, and cannot make silk-like fabrics achieve the natural texture of real silk and cotton; Carried out during the alkali reduction process, the process is long, the energy consumption is high, and the whiteness of the fabric is not easy to control; and the whole process takes a long time (only the whitening process takes 90 minutes for 1,000 meters of cloth), and high energy consumption (production of 1,000 meters of imitation silk cloth 9 tons of water consumption), high pollution, and the imitation silk fabrics produced are of low grade and low added value
