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 woolen fabric into the low-temperature plasma reaction chamber, vacuumize, and when the pressure in the reaction chamber reaches 4Pa, start to introduce air to balance the vacuum degree in the reaction chamber at 26Pa, then perform glow discharge, and use 100W power for 30min discharge treatment.

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

Embodiment 2

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

[0036] Finishing process: except that 30 g / L of AV-910 amino-modified silicon softener was further included in the finishing liquid, the same finishing as in the above-mentioned Example 1 was carried out.

Embodiment 3

[0038] Low-temperature plasma treatment: low-temperature plasma treatment: put the wool fabric into the low-temperature plasma reaction chamber, vacuumize, and start to introduce oxygen when the pressure in the reaction chamber reaches 7Pa to balance the vacuum degree in the reaction chamber at 160Pa, and then perform glow discharge. Discharge treatment with 50W power for 60min.

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

Abstract

A method for treating nano woolen fabrics with chitin in finishing process is carried out by putting fabrics into a treating chamber to treat in low temperature unpolymerable gas plasma at 10-170Pa and power of 10-300W to obtain woolen fabrics with nano-grade concave-convex surface; soaking in aqueous chitin solution of 0.5-10g / L at 25-40 deg.C, squeezing out solution of 70-90%, pre-roasting at 70-90 deg.C, and roasting at 100 - 160 deg.C. Furthermore, a softening agent of 20 - 60g / L can be added into the said chitin solution. Non-yellowing and soft feeling and machine washable woolen fabrics can be obtained, with good profits and without AOX discharge.

Description

technical field [0001] 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. Background technique [0002] As a natural fiber, wool has always been a relatively high-end textile raw material and is deeply loved by consumers because of its soft feel, firm texture, good curl elasticity and warmth retention, and natural and soft luster. However, the special scale structure on the wool surface and its directional friction effect cause felting of the wool fabric during the washing process, which affects its style and dimensional stability. [0003] The wool anti-felting methods include chemical degradation methods such as chlorination method, oxidation method, biological enzyme method and polymer deposition method. The chlorination method is to use chlorine-containing ...
