Embodiment 1

[0032] A tussah silk fabric modified by functionalized nano-chitosan and nano-titanium dioxide is characterized in that the tussah silk fabric modified by functionalized nano-chitosan and nano-titanium dioxide is woven tussah silk fabric by tussah filaments, prepared Finishing liquid and the steps of carrying out tussah silk fabric finishing are prepared; wherein:

[0033] 1. Weaving tussah silk fabrics with tussah silk long fibers: wash the selected tussah silk with high uniformity to remove impurities, then open and card, and then fabric preparation; Tussah filaments with high uniformity were completely soaked in soda water with a temperature of 32-34°C and a concentration of 7.6g / L for 24-27 minutes, and then completely soaked in low-temperature distilled water at a temperature of 27-29°C for 22-24 minutes. min, then take out tussah silk and carry out low-temperature indirect dehydration and drying at a low temperature of 26-28°C; the opening and carding is to uniformly spr...

Embodiment 2

[0038] 1. At room temperature, add 5g / L chitosan to 10g / L butane tetracarboxylic acid and 10g / L sodium hypophosphite to fully dissolve, then add an appropriate amount of dispersant polyvinylpyrrolidone, stir well and disperse evenly, then stir vigorously Add 20g / L sodium tripolyphosphate solution drop by drop to make a nano-chitosan dispersion, then add 10g / L amino silicone oil, 5g / L anatase nano-titanium dioxide, and get nano-TiO 2 Dispersed finishing solution with nano-chitosan;

[0039] 2. Immerse the tussah silk fabric in the above finishing solution for 10 minutes, two dipping and two rolling, the liquid retention rate is 90%, pre-baking at 80°C for 5 minutes, baking at 165°C for 3 minutes, washing and drying at 80°C. The prepared nano-material modified functionalized tussah silk fabric has a wrinkle recovery angle of 253°, an antibacterial rate of more than 95% against Escherichia coli and Staphylococcus aureus, and an improved color depth K / S value for acid dyes and rea...

Embodiment 3

[0041] 1. At room temperature, add 5g / L chitosan to 50g / L butane tetracarboxylic acid and 50g / L sodium hypophosphite to fully dissolve, then add an appropriate amount of dispersant polyvinylpyrrolidone, stir well and disperse evenly, then add drop by drop 20g / L sodium tripolyphosphate solution, then add 10g / L amino silicone oil, 5g / L anatase nano-titanium dioxide, and get nano-TiO2 after vigorous stirring 2 Dispersed finishing solution with nano-chitosan;

[0042] 2. Immerse the tussah silk fabric in the above finishing solution for 10 minutes, two dipping and two rolling, the liquid retention rate is 90%, pre-baking at 80°C for 5 minutes, baking at 165°C for 3 minutes, washing and drying at 80°C. The prepared nano-chitosan and nano-titanium dioxide modified functionalized tussah silk fabric has a wrinkle recovery angle of 253°, a bacteriostatic rate of 100% against Escherichia coli and Staphylococcus aureus, and a color depth value of acid dyes and reactive dyes. K / S value i...

Abstract

The invention relates to modified tussah silk fabric with functionalized nanometer chitosan and nanometer titanium dioxide. The modified tussah silk fabric is prepared by the steps in sequence: weaving the tussah silk fabric by utilizing tussah filament, preparing finishing liquor and finishing tussah silk fabric; and the technical problems that the existing textile materials in the modification technology can not effectively improve the properties that the tussah silk fabric has damage to the environment, is easy to wrinkle, not anti-bacterial and easy to shrink, has poor dyeing property, poor comfortableness and function, and the like can be solved, the comprehensive properties that the tussah silk fabric is anti-wrinkle, soft, anti-bacterial, shrink-proof, self-cleaning and ultraviolet ray-resistant, as well as the adsorption efficiency of dye, and the like can be improved and enhanced, and the tussah silk fabric has the technical benefits of being lower in preparation cost, simple in process, environment-friendly and easy to realize, etc.

Description

technical field [0001] The invention belongs to the technical field of textile material modification, in particular to the technical field of functionalized nano-tussah silk fabric finishing, in particular to a functionalized nano-chitosan and nano-titanium dioxide modified tussah silk fabric. 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 ...
