Manufacturing technique for machine washable slubbing pure wool fabric

Abstract

The invention discloses a manufacturing process of woolen machine-washable pure wool fabric, which adds a protease treatment process on the basis of the traditional woolen wool fabric production process, including the protease treatment process of raw wool fiber and the protease treatment process of fabric. The protease treatment process of raw wool fiber is to remove 30-50% of the scales on the surface of raw wool fiber through protease treatment before the wool processing process; the protease treatment process of fabric is after the shrinking process and in the wet inspection process Previously, the fabric was treated with protease to remove the remaining scales on the surface of the raw wool fibers. Compared with the prior art, the pure wool fabric manufactured by adopting the manufacturing process of the slubbed machine-washable pure wool fabric of the present invention not only has excellent and stable anti-felting effect, but also can be washed by a household washing machine, and the fabric feels good and has a plump surface; in addition, The process is environmentally friendly, green and pollution-free.

Description

technical field [0001] The invention relates to a production method of a fabric, in particular to a manufacturing process of a slub machine-washable pure wool fabric. Background technique [0002] With the improvement of people's living standards, people's demand for textile fabrics is getting higher and higher. For a long time, wool textiles, especially pure wool textiles, have always occupied an important position in the high-end fabric market. However, due to the many scale structures on the surface of wool fiber, these scales are prone to felting when they move in two directions, especially under the conditions of humidity, high temperature and external force. This makes pure wool textile fabrics can not be washed with water easily, especially can not be machine-washed with household washing machines, so the market promotion of pure wool textile products has been limited to a large extent. [0003] In order to improve the anti-felting ability of pure wool textile fabri...

However, although the ozone used in this method can purify the air in a small amount, it is not clear whether workers will be exposed to it for a long time.

In addition, the Chinese patent document with the authorization number CN101130912B discloses a processing method for machine-washable wool shirt fabrics. In addition to adding a small amount of antistatic agents and other auxiliary agents, the method utilizes multiple times of piece dyeing, multiple desiccating and setting. To overcome fabric felt shrinkage, but this method still involves the use of antistatic additives, etc.; the disadvantage of using such antistatic additives is: after the fabric is washed repeatedly, the amount of antistatic agent attached to the surface of the fabric will gradually decrease, and the fabric's The resistance to felting will also gradually decrease

In addition, "Wool Spinning Technology" in the 8th issue of 2007 disclosed a machine-washable all-wool thin tweed developed by the protease method. The environmental protection performance of the process is good, and protease can also play the role of stripping wool fiber surface scales like chloride; however, although the fabric is bright in color, smooth to the touch and good in drapability after processing by this method, due to the relatively large protease molecule, It is difficult to fully penetrate the wool fiber surface inside the fabric to completely remove the scales, so its anti-felting performance has limited improvement

On the contrary, our company found that if all the scales on the surface of the wool fiber are completely removed before wool blending, it is difficult to achieve the fullness of the woolen fabric through shrinking during finishing, and the fabric feels rough and not soft
