Problems solved by technology

However, the cotton fiber has poor elasticity, and it is easy to wrinkle, not crisp, and not beautiful during wearing and washing, which brings a lot of inconvenience to people's life.
In order to overcome the inherent shortcomings of natural cotton fibers, people use the method of non-ironing finishing to improve it. At present, almost all non-ironing finishing uses resin dipping, and then bakes at a high temperature of 150-180°C to achieve the non-ironing of cotton fabrics. Ironing finishing, but because the resin and cotton fiber react under high temperature drying, the reaction speed is relatively fast, which is easy to cause a decrease in strength, but the reaction is mostly carried out in the amorphous area of ​​the fiber, which is uneven, resulting in poor non-ironing effect

Embodiment Construction

[0007] Its technological process is:

[0008] 1. Fabric preparation: The process flow of fabric preparation: the front and back sides of the gray fabric must be consistent when sewing, the seam head should be straight and firm, the singeing process must be clean, the desizing process must be clean, and the desizing rate should reach 98%. Above, in order to ensure the non-ironing effect and feel, alkali mercerizing requires sufficient mercerization, the pH value of the cloth surface is between 7-8, after finishing with liquid ammonia, add 1.5g / L acetic acid to the last tank of the liquid ammonia washing equipment, and the fabric The pH value is adjusted between 5-6, so that the resin can fully react chemically during non-ironing finishing.

[0009] 2. Pre-softening: It is carried out on a stenter frame. Its components and weight ratio are: pre-softening agent UFH 30g / L, acetic acid 1.5g / L, and the rest is water. The temperature of the drying room is controlled at 90°C, and the ...

Abstract

The no-ironing finishing process of pure cotton textile includes the available steps of preparation, preflexibilizing, framing and settling, calendering, preshinking and packing as well as increased rolling supercrosslinking assistant, storing and water washing steps inserted between available preflexibilizing and framing steps. The textile after the said treating process is soft, permeable, water absorbing and no need of ironing and has low formaldehyde content.

Description

technical field [0001] The invention relates to a fabric finishing process, in particular to a non-ironing finishing method for pure cotton fabrics. Background technique [0002] Cotton fabric has always been the best-selling textile in the world. It is favored by people because of its bright colors, good air permeability, strong hygroscopicity, comfortable wearing, soft hand feeling, cheap price, and biodegradation. However, the cotton fiber has poor elasticity, and it is easy to wrinkle, not crisp, and not beautiful during wearing and washing, which brings a lot of inconvenience to people's lives. In order to overcome the inherent shortcomings of natural cotton fibers, people use the method of non-ironing finishing to improve it. At present, almost all non-ironing finishing uses resin dipping, and then bakes at a high temperature of 150-180°C to achieve the non-ironing of cotton fabrics. Ironing finishing, but because the resin and cotton fiber react under high temperatur...
