Abstract

The invention discloses a method for simulating velvet burnt-out by polyamide ammonia. The method comprises the following steps: preparing a gray fabric; pre-moulding; shearing in a circle manner; performing burnt discharge; dyeing; rolling to be soft; drying and sizing; ironing and shearing; and moulding a finished product. By adopting three different kinds of fibers in the raw materials, chinlon in chinlon-covered ammonia in a base fabric is alkaline-resistant but not acidproof, wool dacron is not alkaline-resistant, and all wool with patterns are fully burnt out by using caustic soda during burnt discharge to expose the chinlon-covered ammonia base fabric, so that the third dimension is strong and the burnt discharge effect of true velvets is achieved. As the base fabric contains spandex, a product is good in elasticity and strong in serviceability and not only can be used for making jackets, but also can be used for making underwear, so that the using field of a shell fabric is expanded, and the product can be used for making various spinning products such as home textiles, decorative products, costumes, and toys. The product is high in grade, low in price and high in quality. As the base fabric is too large in elasticity and cannot be galled, the structure of the gray fabric is changed to a pile loop structure, and wool is generated by shearing in the circle manner.

Description

technical field [0001] The invention relates to the field of fabrics in the textile industry, in particular to a method for imitating velvet burnout of polyester nylon ammonia. Background technique [0002] 1. The basic principle of traditional velvet burnt-out [0003] The traditional velvet suede is light viscose filament, and the bottom is mulberry silk. The velvet burnt-out uses the difference in the reaction of two different fibers to strong acids, and the viscose fiber breaks and dissolves to make part of it transparent. The bottom is exposed, and some places produce lines and patterns, which become a special processing method with three-dimensional and transparent patterns. Generally, the sensitivity of the viscose to acid is used to make it break and dissolve. The principle is as follows. Under strong acid, the viscose The degree of polymerization will decrease. At this time, the strength will decrease first, and finally it will become a single molecule of gluco...
