Problems solved by technology

With the continuous improvement of living standards in our country, people are no longer satisfied with general cotton and chemical fiber products in dressing. Improving the comfort of wearing is the direction of future market consumption. stage, there are very few large-scale manufacturers in the market, mainly because the finishing technology is immature, and there is no complete, perfect and continuous production process

Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment.

[0025] Cupro ammonia fiber has been mass-produced in some units in southern my country, and the style is close to the effect of foreign countries, but the production efficiency is low, the yield is also low, and the process is troublesome. Our company uses the existing equipment to develop the company's unique new technology, which makes the cupro ammonia fiber fabric soft like silk, soft in luster and comfortable to wear.

[0026] 1. Cupro ammonia fabric processing process and conditions

[0027] Process: refining and bleaching, sand washing, acetic acid neutralization, dyeing, air finishing, shaping.

[0028] 1. Refining and bleaching process conditions:

[0029] Alkali surface: 3g / l, refining agent: 2g / l, hydrogen peroxide: 3g / l, stabilizer: 1g / l, softener in bath: 5-6g / l, temperature: 90-95℃;

[0030] 2. Sand washing process conditions:

[0031] Caustic soda: 20g / l, softener ...

Abstract

Provided is a copper ammonia fiber fabric dyeing and finishing process. The process includes refining and bleaching, washing by sand, neutralizing by acetic acid, dyeing, finishing by airflow, stereotyping and other steps. Unique process conditions are applied in each process. The beneficial effect of the present invention are that: the realization of the process overcomes technical difficulties of copper ammonia fibers in dyeing and finishing aspects, excellent characteristics of the copper ammonia fibers are fully used, the copper ammonia fibers are soft in hand feel, shiny and soft, have silk feeling, service performance is similar to silk, and the fibers accord with environmental protection clothing trends. The development and technology breakthrough of the product provide a reference for development of high-grade and functional textile fabric, provide guidance to market development, and create a good economic benefit for enterprises.

Description

(1) Technical field [0001] The invention relates to a fabric manufacturing process in the textile field, in particular to a dyeing and finishing process of cupro ammonia fiber fabric. (2) Background technology [0002] Cupro fiber is a kind of regenerated cellulose fiber. The cross-section of the fiber is round and has no sheath-core structure. The fiber can withstand high stretching. The monofilament is relatively thin. In addition, the dyeing affinity is greater than that of viscose fiber, the color is darker, the moisture absorption is good, and it has a great drape feeling. The wearing performance is similar to silk, which is in line with the trend of environmental protection clothing. At present, only the United States, Japan, Britain, Germany, and Italy produce in the world. With the continuous improvement of living standards in our country, people are no longer satisfied with general cotton and chemical fiber products in dressing. Improving the comfort of wearing is ...
