Equipment for non-shrink treatment of wool raw materials and products

Abstract

The invention relates to equipment for non-shrink treatment of wool raw materials and products. Specifically, the equipment comprises a multiple padding device, a washing device, an enzyme inactivation device, an optional softness treatment device and an optional dryer, wherein the multiple padding device comprises n independent padding devices arranged continuously, each padding device comprises a soaking tank and a roller, and n is a positive integer ranging from 2 to 20; the washing device is used for washing padded wool tops or wool products, and washed wool tops or wool products are formed. The equipment further comprises transmission devices located between the padding devices and non-shrink treatment liquid supplementing devices located obliquely above the downstream parts of the transmission devices. The equipment can meet the requirement for non-shrink processing treatment of wool tops and wool products, is environmentally friendly, can achieve continuous operation, has the advantages of uniform treatment and high efficiency and is quite suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of wool product processing, in particular to equipment for shrink-proof treatment of wool raw materials and products. Background technique [0002] Wool is an important raw material for the textile industry. It has many excellent properties, such as good elasticity, strong hygroscopicity, not easy to stain, good warmth retention, and soft luster. As a natural protein fiber, wool has a layer of overlapping fish scales mainly composed of keratin on the surface. Due to the different friction coefficients in the forward and reverse directions of the scales, the wool fibers will intersect each other under repeated external forces. Entanglement, cross-knitting, and felting produce fluffing. Although milling makes the wool fabric have beautiful appearance, rich and soft hand feeling, and good thermal performance, it also makes the wool fabric prone to shrinkage and deformation during washing. Therefore, in order to improve...

AI Technical Summary

Problems solved by technology

However, the anti-shrinkage effect of wool treated with protease alone cannot meet the actual needs at present, so when many adopt protease to carry out biological modification of wool, it is necessary to pre-treat the wool first (such as using strong oxidant permanganate Potassium, etc., or pretreatment with chloride solvents)

The above pretreatment methods all have shortcomings such as long treatment time, easy inactivation of enzymes, and difficult control of treatment conditions.

[0005] In addition, although some researchers try to develop a chlorine-free anti-shrinkage treatment process for wool raw materials, there are the following disadvantages: (a) the treatment time is long (it cannot be shortened to less than 30 minutes while ensuring the treatment quality); (b) The processing capacity is limited, which is not suitable for industrial applications; (c) the processing quality fluctuates greatly, and it is difficult to obtain wool processing products with uniform processing effect

Therefore, in China and other major wool raw material processing countries, there is currently no situation in which the chlorine-free anti-shrinkage treatment process is used to process wool raw materials in actual production.
