Embodiment 1
[0025] A method for non-ironing finishing that can enhance the tear strength of cotton fabrics, the specific method is as follows:
[0026] 1) Soak the cotton fabric in a sodium hydroxide solution with a concentration of 0.1mol / L, treat it in a water bath at 60°C for 30 minutes, then wash it with distilled water until neutral, and then use acetone, absolute ethanol, and deionized water in sequence Perform ultrasonic cleaning for 10 minutes, and dry at 50°C after washing;
[0027] 2) Put the dried cotton fabric into -100°C environment for freezing treatment for 3 hours, then slowly raise the temperature to room temperature, keep it warm at room temperature for 3 hours, and repeat the treatment 5 times by using the method of freezing + returning to temperature interactive treatment, and then After washing the treated cotton fabric, dry it at 50°C;
[0028]3) Add the modified nano-antimony sulfide graft polymer powder into distilled water, mix and stir to prepare an aqueous solu...
