Problems solved by technology

[0006] my country is a large oceanic country. Although the output and production capacity of chitin series products are considerable, most of them are semi-finished products or batch products that are purchased cheaply by foreign manufacturers and sold back to my country at high prices in refined small packages, resulting in the loss of resources and the loss of economic benefits.

Embodiment 1

[0032] Low-temperature plasma treatment: Put the wool fabric into the low-temperature plasma reaction chamber and vacuum, when the pressure in the reaction chamber reaches 4Pa, start to pass air to balance the vacuum in the reaction chamber at 26 Pa, and then perform glow discharge with 100W power. 30min discharge treatment.

[0033] Finishing process: immerse the wool fabric treated with the above low-temperature plasma in a finishing solution containing 2g / L of chitin at 35°C for 30 minutes, take out the padding solution, the padding rate is 90%, and then pre-bake at 90°C for 8 minutes , And bake at 130°C for 2min.

Embodiment 2

[0035] Low-temperature plasma treatment: the wool fabric is put into a low-temperature plasma reaction chamber, and the same low-temperature plasma treatment as in the above-mentioned embodiment 1 is performed.

[0036] Finishing process: the same finishing as in Example 1 was performed except that 30 g / L of AV-910 amino-modified silicon softener was further contained in the finishing liquid.

Embodiment 3

[0038] Low-temperature plasma treatment: low-temperature plasma treatment: put the wool fabric into the low-temperature plasma reaction chamber, vacuum, and when the pressure in the reaction chamber reaches 7Pa, oxygen is introduced to balance the vacuum in the reaction chamber at 160Pa, and then glow discharge is performed. Use 50W power for 60min discharge treatment.

[0039] Finishing process: immerse the wool fabric treated with the above low temperature plasma in a finishing solution containing 2.5g / L of chitin at 40°C for 25 minutes, take out the padding solution, the padding rate is 80%, and then pre-baking at 80°C 10min, and bake at 110°C for 3min.

Abstract

The invention belongs to the field of functional processing of textiles, and in particular relates to machine-washable wool fabrics obtained by finishing wool fabrics with nanostructures on the fiber surface and a preparation method thereof. The wool fabric is put into the processing chamber, and the non-polymerizable gas low-temperature plasma treatment is carried out under the pressure of 10-170Pa and the power of 10-300W, so as to obtain the wool fabric with nano-scale concave-convex shape structure on the fiber surface. Then use a chitin aqueous solution with a concentration of 0.5-10g / L, impregnate at a temperature of 25-40°C, squeeze out a rate of 70-90%, pre-bake at 70-90°C, and bake at 100-160°C. The chitin finishing solution may further contain 20-60 g / L softener. The invention has no AOX emission, can obtain environment-friendly machine-washable wool fabric with excellent effect, no yellowing and soft hand feeling, and has remarkable economic and social benefits.

Description

Technical field [0001] The invention belongs to the field of functional processing of textiles, and particularly relates to a machine washable wool fabric obtained by chitin finishing a wool fabric with a nanostructure on the fiber surface and a preparation method thereof. Background technique [0002] As a natural fiber, wool has a soft hand, firm texture, good curling elasticity, warmth retention, and natural and soft luster. It has always been a relatively high-end textile material and is deeply loved by consumers. However, the special scale structure of the wool surface and its directional friction effect make the wool fabric felt shrinkage during the washing process, which affects its style and dimensional stability. [0003] The methods of wool anti-felting include chlorination, oxidation, biological enzymatic and other chemical degradation methods and polymer deposition methods. The chlorination method uses chlorine-containing compounds to destroy t...
