Description
Technical field
The invention belongs to textile function auxiliary agent field, particularly a kind of emulsion containing Nano Silver microspheres with solid and preparation method thereof and the application in tatting or knit fabric.
Background technology
Functional treatment method a kind ofly in conventional tatting or knit fabric, is padded functional aid and make it have the method for certain function, and functional aid can be selected according to the raw materials used performance of fabric and the specific function will giving fabric.Along with the development of science and technology and the raising day by day of human living standard, people more trend towards environmental protection, health to the pursuit of quality of the life, and the antibacterial problem of tatting or knit fabric more and more causes the great attention of countries in the world.Therefore, developing a kind of antibiotic finishing method that is safe, durable, that have universality is very helpful to improving people's quality of the life.
At present, external antibacterial tatting or knit fabric oneself enter the stable development stage, wherein Japan and the U.S. maintain the leading position, and the research of China to antibacterial tatting or knit fabric is still in the starting stage, antibiotic fabric is desirable not enough in broad-spectrum antiseptic, water-fastness, chemical-resistant reagent etc., lacks international competitiveness.Therefore, strengthen the research and development of antibacterial fabric, healthy to protection people, the class improving textiles has great meaning.From antibacterial effect and persistence, the antibacterial finishing agent (comprising nano antibacterial finishing agent) with durable antibiotic effect of development of new and study the new trend that new antibacterial finishing process is antibacterial fabric research, its market prospects are very wide.
Nano Silver is considered to a kind of nontoxic, environment-friendly material, and there is good antibiotic property, be widely used in various antibiotic preparation, solve effective substitute products [Hao Xihai that organic antibacterial agent abuses microbial resistance and the environmental pollution caused, Sun Miao, Deng Jing. the progress of anti-biotic material. Chemical Engineering Technology and exploitation 2011,40:21-24.].Nano Silver has a wide range of applications in textile garment field, such as fiber, fabric, underwear, T-shirt, sweater, socks product, knee-pad, bedding etc.With regard to the Underwear market of national women and children, the consumer group about 700,000,000 people, the annual underwear selling more than 2,000,000,000.If after every part underwear adopts nano silver antimicrobials, increase the added value of 5 – 10 yuan, then the market of 50% just can realize the output value of more than 50 hundred million yuan.
Argentiferous gel preparation is the novel antibacterial preparation studying and use a more class at present.The argentiferous gel preparation of current commercial type and use uses silver salt and high molecular polymer to mix mostly, i.e. gel preparation [the horse Yulong of carrying silver ion, Xu Zirong.
