Embodiment 1
[0029] The production method of the dirt-repelling and anti-felting wool fabric of embodiment 1 comprises the steps:
[0030] S1: Pre-oxidation treatment of wool fabric, soak wool fabric in hydrogen peroxide solution, heat up to 60°C, keep warm for 0.5h, the content of hydrogen peroxide in hydrogen peroxide solution is 7ml / L, then take out the fabric and dry;
[0031] S2: Foaming the chitosan acid solution on the surface of one side of the wool fabric, the concentration of chitosan in the chitosan acid solution is 0.5%, drying naturally, washing and drying, and placing the wool fabric in a low-temperature atmosphere for plasma treatment ;
[0032] S3: Configure chitosan silica sol finishing solution. The main components of chitosan silica sol finishing solution are chitosan, silicon dioxide, organic polyacids, water, and the pH of chitosan silica sol finishing solution is 5. The percentage by weight of chitosan in the polysaccharide silica sol finishing solution is 0.5%, and th...
Embodiment 2
[0038] Embodiment 2 is based on embodiment 1, the difference is:
[0039] The pre-oxidation treatment temperature of wool fabric is 80°C, keep warm for 1.5h, and the content of hydrogen peroxide in the hydrogen peroxide solution is 12ml / L;
[0040] The chitosan concentration in the chitosan acid solution is 2%; the pH of the chitosan silica sol finishing solution is 3.5, and the weight percentage of chitosan in the chitosan silica sol finishing solution is 3%, and the chitosan silica The silicon content of the sol finishing solution is 5%.
[0041] In the medium and low temperature plasma treatment process of S2, the non-polymerizable gas in the chamber of the plasma treatment device is argon, the applied voltage discharge frequency is 13.75MHz, the power is 200W, and the treatment time is 20s.
[0042] The preparation process of chitosan silica sol finishing solution in S3 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqueous solution, adding wat...
Embodiment 3
[0044] Embodiment 3 is based on embodiment 2, the difference is:
[0045] The temperature of wool fabric pre-oxidation treatment is 70°C, heat preservation for 1 hour, and the content of hydrogen peroxide in the hydrogen peroxide solution is 9.5ml / L;
[0046] The chitosan concentration in the chitosan acid solution is 1.2%; the pH of the chitosan silica sol finishing solution is 4.2, and the weight percentage of chitosan in the chitosan silica sol finishing solution is 1.7%, and the chitosan silicon The silicon content of the sol finishing solution is 3.5%.
[0047] In the medium and low temperature plasma treatment process of S2, the non-polymerizable gas in the chamber of the plasma treatment device is ammonia gas, the applied voltage discharge frequency is 13.75MHz, the power is 100W, and the treatment time is 100s.
[0048] The preparation process of chitosan silica sol finishing solution in S3 is: dissolving chitosan in the chitosan mixed solution in the organic acid aqu...
