Problems solved by technology

However, the current processing method of nano-functional silk textiles generally adopts post-finishing technology, that is, the functional nano-powder is prepared into a certain water dispersion system, and then the nano-material is attached to the surface of the fabric by dipping, rolling, and drying. The combination of fabrics depends on the role of adhesives, which greatly affects the feel and safety of silk fabrics, and the dispersion of functional nano-powders cannot be effectively resolved. The final materials adsorbed or embedded on the fabrics are not nanometers but micrometers. , nano-finished textiles often do not have nano-functions, or the nano-functions cannot be fully reflected
Therefore, the in-situ synthesis of nanoparticles on fabrics to endow fabrics with nano-functions has aroused people's strong interest. There have been reports on the in-situ synthesis of nanoparticles on cotton fabrics at home and abroad, but there is no domestic report on the in-situ nano-functional finishing of silk fabrics. Reports, foreign reports are also less, such as literature [Colloids and surfacesA, 2006 (289)] reported a kind of antibacterial finishing of nano-silver to real silk fabrics, by producing nano-silver in polyacrylate aqueous solution and then adopting the method of dipping to coat to the fabric surface

Embodiment 1

[0022] Immerse the silk gray cloth in the treatment solution composed of sodium carbonate with a pH value of 7.5 and 2709 alkaline protease, and treat it at 50°C for 40 minutes to make the sericin on the surface of the silk gel and produce a slight hydrolysis, and rinse it with warm water at 60°C 1min, the obtained sericin content is 11% and the residual sericin is evenly distributed and the rubber-containing fabric with fluffy structure; the glue-containing fabric is immersed in the water-soluble metal salt Zn(NO 3 ) 2 In the solution, treat at room temperature for 30 minutes, roll off excess water in a rolling car, enter a steam room containing ammonia water / ethanol with a volume ratio of 1:1, treat at 75°C for 60 minutes, and enter a heat setting machine for pre-treatment at 80°C. Bake for 2 minutes at 120°C for 2 minutes; put the fabric in a soap solution containing 3g / L of soda ash and 1g / L of soap at 60 Treat at ℃ for 30 minutes, rinse in clean water, and dry to obtain ...

Embodiment 2

[0029] The silk gray cloth was immersed in a buffered alkaline solution composed of sodium carbonate and sodium bicarbonate with a pH value of 9.8, treated at 78°C for 30 minutes, rinsed with warm water at 60°C for 1 minute, and immersed in 0.3mol / L Zn(NO 3 ) 2 solution, treat at room temperature for 30min, roll off the excess water in the rolling car, enter the steam room containing ammonia water / methanol with a volume ratio of 1:1, treat at 65°C for 60min, and pre-heat at 80°C in the heat setting machine. Bake for 2 minutes at 120°C for 2 minutes; put the fabric in a soap solution containing 3g / L of soda ash and 1g / L of soap at 60 It was treated at ℃ for 30 minutes, then rinsed in clean water, and then dried to obtain the glue-containing nano-functional silk fabric. The test results show that the obtained fabric contains 11 percent sericin, a UPF index of 35, and a bacteriostatic rate of more than 95 percent against Escherichia coli and Staphylococcus aureus.

Embodiment 3

[0031] Immerse the silk fabric in the treatment solution composed of sodium carbonate with a pH value of 7.5 and 2709 alkaline protease, treat it at 50°C for 40 minutes, rinse it with warm water at 60°C for 1 minute, and immerse it in 0.5mol / L Mg(NO 3 ) 2 In the solution, treat at room temperature for 30 minutes, roll off excess water in a paddle car, and then enter a steam chamber containing ammonia water / (ethanol 1 / 2+methanol 1 / 2) at a volume ratio of 2:1, and treat at 70°C for 60 minutes. Pre-bake at 80°C for 2 minutes in a heat setting machine, and bake at 110°C for 4 minutes; put the fabric in 3g / L soda ash and 1g / L at a bath ratio of 1:30 (ratio of fabric weight to washing liquid volume). Treat L soap in a soap alkali solution at 60° C. for 30 minutes, then rinse in clean water, and dry to obtain a glue-containing nano-functional silk fabric.

Abstract

The invention discloses a method for adhering sericin and nanometer materials on real silk fabrics; at first, partial degumming treatment is carried out on the real silk fabrics to obtain the real silk fabrics containing 10 to 15 percent of the sericin; then the method of dipping, padding or spraying is adopted to carry out treatment on the real silk fabrics in soluble metal saline solution with a concentration of 0.1 to 0.5mol / L; then real silk products with various nanometer functions like antibiosis, UV resistance and static resistance are obtained by treating the real silk fabrics in alkali vapors of 60 to 80 DEG C for 30 to 120 minutes. The process of the method is simple, saves energy, protects environment, can be carried out on the traditional dyeing device, has high working efficiency and is extremely easy to be popularized and applied.

Description

technical field [0001] The invention relates to a method for processing functional textiles, in particular to a method for fixing sericin and nanometer materials on silk fabrics, and belongs to the technical field of textile finishing. Background technique [0002] The traditional silk industry mainly uses the inner silk fibroin part of the silk, while the outer sericin part of the silk (generally accounting for more than 20% of the weight of the whole gray silk) needs to be pre-treated to remove it and be treated with waste water. This is not only a waste of resources to the birthplace of silk in our country, but also not conducive to environmental protection. How to preserve or recycle sericin, a natural resource, has aroused widespread interest of researchers. Among them, the fixation of sericin has always been a subject of attention, because the fixation of sericin not only saves resources and saves the pre-treatment process of degumming, but also can produce plump, thi...
