Embodiment 1-3 and comparative example 1-4

[0042] A continuous processing method for improving the milling resistance of wool fabrics, comprising the following steps:

[0043] S1. preparing an aqueous solution comprising 1wt% to 5wt% of sodium hypochlorite and 1wt% to 3wt% of ethanol as a treatment solution, and padding the woolen fabric in the treatment solution, with a residual rate of 80 to 100%;

[0044] S2. Import the wool fabric treated in step S1 into an ozone chamber (ozone concentration is 8-12g / h) in a tension-free long-loop manner, and after ozone treatment for 10-30min, wash and dry to obtain milling-resistant wool fabric.

[0045] Wherein, the inlet and outlet of the ozone chamber adopt a liquid seal structure, and the liquid seal structure of the inlet adopts the above-mentioned treatment liquid as the liquid seal liquid, and the liquid seal structure of the outlet adopts water as the liquid seal liquid.

[0046] Use GB / T 8629-2017 "Household Washing and Drying Procedures for Textile Testing" standard fo...

Abstract

The invention provides a continuous processing method and device for improving the fulling resistance of a wool fabric. According to the continuous processing method, a liquid sealing device consisting of sodium hypochlorite and ethanol treatment liquid and an ozone gas chamber is adopted, firstly, the wool fabric is subjected to padding treatment in the treatment liquid, then enters the ozone gas chamber in a tension-free long-loop manner for ozone treatment, and then is guided out through a washing water liquid sealing structure at an outlet, so that the continuous anti-fulling processing of the wool fabric is realized, wherein sodium hypochlorite in the treatment liquid can have an oxidation etching effect on scales on the surfaces of wool fibers, and the treatment effect of the sodium hypochlorite can be improved due to the strong permeation effect of ethanol; further oxidation etching is conducted on the scales on the surfaces of the wool fibers by utilizing the strong oxidation effect of ozone; and finally, water seal at the outlet can play a certain washing role, so that the aim of continuously preventing the fulling of the wool fabric is fulfilled.

Description

technical field [0001] The invention relates to the technical field of wool fabric preparation, in particular to a continuous processing method and device for improving the milling resistance of wool fabric. Background technique [0002] Wool is mainly composed of protein. Wool fibers are soft and elastic, and can be used to make textiles such as woolen wool, woolen yarn, blankets, and felt. Wool products have the characteristics of fullness, good warmth retention and comfortable wearing. They are famous for their luxurious, elegant and comfortable natural style, especially cashmere, which has the reputation of "soft gold". However, the surface of wool fiber is covered with a layer of dense scale layer and hydrophobic phospholipid layer, resulting in poor wettability of wool, easy felting and deformation, and breeding of bacteria, which greatly restricts the use of wool fabric. Therefore, it is very necessary to modify the wool fiber to improve the machine washability, aes...
