Description

A kind of anti-bacterial fibre and preparation method thereof
Technical field
The present invention relates to a kind of fiber, particularly a kind of anti-bacterial fibre and preparation method thereof, belong to textile technology field.
Background technology
In daily life, bacterium is ubiquitous, and textiles, in wearing process, absorbs the materials such as secretion, sweat, sebum, be very easy to become vegetative hotbed, under the condition that temperature humidity is applicable to, the reproduction speed of bacterium is very fast, the short bacterium that can breed 1,000,000 quantity for 4 hours.Not only can volatilize in the process and there is the metabolic waste of foul odour, also can cause relevant infectious disease.Therefore towel, underpants, sheet etc. become the best medium of cross infection, significant threat is become to health, therefore, the weaving face fabric with antibacterial functions has extremely important effect for preventing the infringement of germ, and along with the development of science and technology, in the middle of each details extensively and being in depth radiated life, the commodity made of antiseptic weaving face fabric are gradually by people are paid attention to.The antibacterial textile that Nano Silver makes has more report, application number is 201110210130.4, name is called that the patent of invention of " soluble alginate/carboxymethyl carrageenan composite antibacterial fiber and preparation method thereof " discloses a kind of composite antibacterial fibre, adopts wet spinning process to be prepared from by the mixed solution of soluble alginate, carboxymethyl carrageenan and nano silver dispersion; Application number is 201110075463.0, name is called in the patent of invention of " a kind of processing method of Multifunctional composite textile " and adds modified polyorganosiloxane defoamer fully stir after polyurethane and dimethyl formamide mixing, leave standstill after being coated with at twice scraping in release liners oven dry as fabric slurry after more than 12 hours, laminating nano silver fibre base fabric, after finally drying, rolling is peeled off, and leaves standstill and obtains composite textile after 12 hours.But, Nano Silver in the anti-bacterial fibre prepared by said method is adopted to be the top layer being scattered in fiber by adhesive, along with the cleaning Nano Silver of adhesive can run off gradually, cause antibacterial effect permanent and, effect is undesirable, also there is the shortcomings such as fibre strength is inadequate, preparation method is loaded down with trivial details on the other hand.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of preparation method is simple, anti-microbial property is superior and the anti-bacterial fibre that effect is lasting, utilize cellulose xanthate to meet acid and form cellulosic principle, after Nano Silver being adsorbed on core fibers surface, be dipped into further in cellulose xanthate solution and form with acid solution reduction the technical scheme being compounded with the cellulose top layer of Nano Silver again, obtaining take viscose glue as the Nano Silver cotton fiber of modifier, and its preparation method is simple, fibre strength is large, anti-microbial property is lasting.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of anti-bacterial fibre, and the structure of the antibacterial dimension of described fibre comprises the top layer of cotton fiber sandwich layer and Nano Silver/cellulose compound.
The present invention also provides the preparation method of above-mentioned a kind of anti-bacterial fibre, said method comprising the steps of:
1. cotton fiber is soaked in Nano silver solution, tune pH is 7-8, takes out dry, must adsorb the cotton fiber of Nano Silver after soaking 5-30min;
2. the cotton fiber of absorption Nano Silver is soaked in 5-60min in cellulose base xanthates solution, takes out dry, the cotton fiber of the Nano Silver that must bond;
3. the cotton fiber of bonding Nano Silver is soaked 5-30min in sulfuric acid solution, take out washing, drying, obtain anti-bacterial fibre.
In technique scheme, take cotton fiber as sandwich layer, absorption Nano Silver, then the cotton fiber of absorption Nano Silver is soaked in the viscose solution of cellulose base xanthates, Nano Silver is positioned at cotton fiber periphery, further the cotton fiber of bonding Nano Silver is immersed in acid solution, cellulose base xanthates is met acid and is formed cellulose, dispersed nano-silver particles is in viscose glue top layer, formation take viscose glue as the Nano Silver cotton fabric of modifier, its structure is take cotton fiber as sandwich layer, with Nano Silver/cellulose composite for top layer.In this anti-bacterial fibre, few Nano Silver just can produce powerful bactericidal action, strong suppression and killing action is had to multiple pathogenic microorganisms such as Escherichia coli, gonococcus, chlamydia trachomatises, 650 various bacteria can be killed in several minutes, broad-spectrum sterilization and without any drug resistance, on the other hand, the reparation of the healing of wound, the growth of cell and damaged cell can also be promoted, any irritant reaction is not found yet to skin, in field extensive uses such as textile material, medicine equipment and goods, furniture appliance layer.And the Nano Silver in anti-bacterial fibre is and cellulose compound, not simple physical absorption, and there is not Nano Silver and adhesive different in kind and easily coming off of causing, even if therefore cleaning repeatedly also can not come off, not only ensure that antibacterial effect, and environmental friendliness.
The beneficial effect adopting technique scheme to produce is: (1) anti-bacterial fibre of the present invention anti-microbial property is superior, and washing fastness is good.(2) be skillfully constructed, production method is simple, be easy to realize suitability for industrialized production, have huge application potential in the field such as clothes, weaving.
