Problems solved by technology

Dichloroisocyanurate salt chlorination technology or chlorination-Hercosett technology has been applied for more than 20 years, but this mature technology has been greatly impacted abroad in recent years
Although this method avoids the high pollution of the environment caused by the traditional chlorination technology, it uses a solution of copper ions and zinc ions, which will be adsorbed on the wool fiber (such as through the formation of a coordination bond between the copper ion and the polar group on the wool) , so that the metal ions in the textiles exceed the standard. In addition, the physical action is not ideal for removing the scales of the wool top. The friction between the wool and water is limited, and the high-speed rotation will make the wool sliver messy, and even produce a lot of fluff on the surface of the wool sliver, which directly affects the surface finish of wool products.

Embodiment 1

[0021]For undyed wool fibers, the modification process is: wool fiber → pre-oxidation treatment → washing → oxidation treatment → washing → reduction treatment → washing → enzyme hydrolysis treatment → washing → (dyeing → washing) → softening treatment → centrifugal dehydration → drying → modified wool fiber.

[0022] Wool loose fiber: Put 100Kg of loose fiber into the intermittent wool dyeing machine, add 3Kg of sodium percarbonate and 0.9Kg of tetraacetylethylenediamine at 30-32°C, run for 30 minutes, turn on the water, and then use 30-32°C Wash with water for 10 minutes and drain the water. Then, add 0.8Kg high-efficiency penetrant SP-2 and 5Kg ammonium persulfate at 28-30°C, run for 25 minutes, drain water, wash with water at 30-32°C for 10 minutes, and drain water. Next, add 5Kg of sodium metabisulfite at 38-40°C and run for 20 minutes, drain water, and wash with water at 30-32°C for 10 minutes. Continue to heat up to 52-53°C, add 0.8Kg alkaline protease and a certain a...

Embodiment 2

[0024] Wool loose fiber: put 100Kg loose fiber into the intermittent wool dyeing machine, add 5Kg sodium percarbonate and 2.5Kg tetraacetylethylenediamine at 30-32°C, run for 30 minutes, drain water, and then use 30-32°C Wash with water for 10 minutes and drain the water. Then, at 28-30°C, add 0.5Kg of high-efficiency penetrant SP-2 and 4Kg of a mixture of ammonium persulfate and sodium persulfate with a mass ratio of 1:1, run for 30 minutes, drain water, and then use 30-32°C water Wash for 10 minutes and turn on the water. Next, add 4Kg of a mixture of sodium metabisulfite and sodium sulfite with a mass ratio of 1:1 at 38-40°C, run for 25 minutes, drain water, and wash with water at 30-32°C for 10 minutes. Continue to heat up to 52-53°C, add 0.8Kg alkaline protease and a certain amount of soda ash, use pH test paper to test the pH value of the solution to 7.8, run for 25 minutes, continue to heat up to 75°C, run for 10 minutes, turn on the water, and then use 30 Wash in -32...

Embodiment 3

[0026] Wool loose fiber: After enzymatic hydrolysis treatment, wool loose fiber can be dyed with conventional acid dyes, neutral dyes or reactive dyes in intermittent loose wool dyeing machines, and finally softened, dehydrated and dried. The processing conditions relevant to the present invention are the same as in Example 1. It can be used to produce dyed wool modified loose fiber.

[0027] In the technical solution of the present invention, wool dyeing is to use acid dyes, neutral dyes, reactive dyes, cationic dyes, basic dyes, and disperse dyes to prepare dyed wool fibers, wool / acrylic fibers and wool / polyester fibers with conventional dyeing methods.

Abstract

The invention relates to a method for the modification treatment of wool fibre and belongs to the field of dyeing and finishing technology. The method adopts pre-oxidation treatment, oxidation treatment, reduction treatment, enzyme hydrolysis treatment, softening treatment and other modification procedures, can effectively improve the felting property of loose wool fibre, wool yarn, wool strips, wool flower type strips so as to prepare a worsted wool product, so as to achieve the effects of felting prevention and machine washablility, improve the dimension stability of the worsted wool product and simultaneously obtain soft and smooth hand feeling and excellent lustrousness. The standard washing shrinkage rate of the wool clothing product produced through the method is lower than 3 percent.

Description

technical field [0001] The present invention relates to a processing method of modified wool fibers, in particular to wool loose fibers, yarns, tops or worsted wool products with anti-felting performance, soft and smooth hand feeling and "machine washable" performance of finished garments The invention discloses a processing method of modified wool fiber, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] Wool products, such as all kinds of wool, loose wool, tops, yarn, worsted wool products, fancy woolen fabrics, high-grade wool knitted products, wool machine washable clothing, etc., all involve the scales on the surface of wool fibers during the printing and dyeing process. The removal problem is a common problem in the printing and dyeing wool spinning industry. Wool textile products are one of the most complex natural fibers. Due to the special scale organization on the surface of wool, it is difficult to dye and chemical...
