Embodiment example 1

[0040] The preparation steps of ecological multifunctional fabric finishing agent are as follows:

[0041] (1) Boil silk into 0.5% Na by weight 2 CO 3 Degumming in the solution for 3 times, 30 minutes each time, rinsing with hot water for 3 times, then drying at 55°C and cutting into pieces, the amount of silk used is 0.5% Na 2 CO 3 1.5% of the solution.

[0042] (2) According to the molar ratio, anhydrous calcium chloride: ethanol: water = 1:2:8 to make a ternary solution, and dissolve the silk fiber obtained in step (1) in the above ternary solution at 75°C After 180 minutes, filter the fibroin solution, put it into a dialysis bag, place it in clean water for dialysis, change the water every 2 hours, and concentrate it after 3 days of dialysis to obtain a silk fibroin solution. The amount of the above ternary solution is 15 times the dosage.

[0043] (3) Add 3.0mol / L hydrochloric acid solution to the silk fibroin solution in step (2), hydrolyze at 60°C for 150 minutes, ...

[0047] The preparation steps of ecological multifunctional fabric finishing agent are as follows:

[0048] (1) Boil silk into 0.5% Na by weight 2 CO 3 Degumming in the solution 3 times, 30 minutes each time, rinsing 3 times with hot water, then drying and cutting at 65 °C, the amount of silk is 0.5% Na 2 CO 3 3% of the solution.

[0049](2) According to the molar ratio, anhydrous calcium chloride: ethanol: water = 1:2:8 to make a ternary solution, and dissolve the silk fiber obtained in step (1) in the above ternary solution at 75°C After 120 minutes, filter the silk fibroin solution, put it into a dialysis bag, place it in clean water for dialysis, change the water every 3 hours, and get the silk fibroin solution after 3 days of dialysis. The amount of the above ternary solution is the amount of silk 20 times.

[0050] (3) Add 3.0mol / L hydrochloric acid solution to the silk fibroin solution in step (2), hydrolyze at 70°C for 120 minutes, titrate to neutral with 3mol / L so...

Embodiment example 3

[0054] The steps of finishing the cotton fabric with the ecological multifunctional fabric finishing agent containing silk fibroin and chitosan are as follows:

[0055] (1) plain weave cotton fabric (150g / m 2 ) soaked in a sodium hydroxide solution with a concentration of 21% by mass, soaked at room temperature for 30 minutes, took it out, washed with water until neutral, and wrung out to obtain an alkali-treated cotton fabric. The consumption of sodium hydroxide solution is 40 times of cotton fabric weight.

[0056] (2) The alkali-treated cotton fabric obtained in step (1) was dipped twice and rolled twice in the ecological multifunctional fabric finishing agent of Example 1. The ecological multi-functional fabric finishing agent is 30 times the weight of cotton fabric, the soaking time is 40 minutes, and the squeeze rate is 85%.

[0057] (3) The cotton fabric obtained by padding in step (2) was pre-baked at 80°C for 60 minutes, and then baked at 130°C for 3 minutes to comp...

Abstract

The invention discloses a multifunctional textile finishing agent. The multifunctional textile finishing agent comprises the following components in percentage by weight: 1.00 to 5.00 percent of fibroin, 0.01 to 0.10 percent of chitosan, 0.01 to 0.50 percent of titanium dioxide, 0.01 to 1.50 percent of cross-linking agent, 0.50 to 5.00 percent of acetic acid, 0.10 to 0.80 percent of metal salt catalyst and the balance of water. The ecological multifunctional textile finishing agent involved by the invention is made of environment-friendly raw materials, is convenient to process, is not toxic or harmful to a human body and have no pollution; a finishing method is simple and is suitable for industrial production by a padding method; and the appearance of a finished textile is not influenced, namely the color does not turn yellow and the finished textile has a good anti-wrinkle effect and comfortable handfeel.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and relates to a multifunctional fabric finishing agent, a preparation method thereof and a cotton fabric finishing method. Background technique [0002] With the increasing awareness of green environmental protection at home and abroad, the development of formaldehyde-free durable non-ironing finishing agents for textiles has become a development trend. The developed formaldehyde-free finishing agents such as epoxy resin, bishydroxyethyl sulfone, polycarboxylic acid and water-soluble polyurethane have achieved certain results in application, but they all have certain shortcomings such as low timeliness and strong damage , Easy to yellow, especially these finishing agents are chemically synthesized, and some have low toxicity. [0003] Ecological fabric finishing agent has gradually attracted attention in recent years because of its safety, non-toxicity and good biocompatibility. It us...
