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] Dip the grey silk fabric into a treatment solution composed of sodium carbonate with a pH of 7.5 and 2709 alkaline protease, and treat it at 50°C for 40 minutes to solize the sericin on the surface of the silk and cause a slight hydrolysis. Wash it with 60°C warm water In 1 min, a rubber-containing fabric with a sericin content of 11% and a uniform distribution of residual sericin and a fluffy structure is obtained; the rubber-containing fabric is immersed in a water-soluble metal salt Zn(NO) with a concentration of 0.3mol / L 3 ) 2 In the solution, treat at room temperature for 30 minutes. After rolling off the excess water in the rolling car, it enters the steam chamber containing ammonia / ethanol with a volume ratio of 1:1, treats it at 75°C for 60 minutes, and enters the heat setting machine at 80°C. Bake for 2min, and bake for 2min at 120℃; according to the bath ratio 1:30 (ratio of fabric weight to washing liquid volume), put the fabric into a soap alkali solution conta...

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 nano materials on a silk fabric, belonging 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 entire raw silk) must be pre-treated to remove it, and together with the waste water Emissions are 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 the natural resource of sericin has aroused wide interest among researchers. Among them, the fixation of sericin has always been a topic that attracts attention, because the fixation of sericin not only saves resources, saves the pre-treatment process of degumming, but also produces a plump, thick...
