Description
Technical field
The present invention relates to a kind of biological antibacterial carries the preparation method of platinum viscose rayon, belong to viscose rayon technology of preparing neck
Domain.
Background technology
Viscose rayon refers to the cellulose extracted from the cellulosic materials such as cotton linter, timber and straw, processed
Into spinning solution, then staple fibre made by Jing wet spinnings.The chemical composition of viscose rayon is identical with cotton fiber, the degree of polymerization and
Degree of crystallinity is below cotton fiber, and the degree of orientation is relatively low, and structure is also more loose.Therefore viscose rayon absorption property is preferably, with outstanding
Adsorptivity, dyeability and color fastness, viscose rayon good hygroscopicity, comfortable and easy to wear, spinnability is excellent, Chang Yumian, hair etc. or various
Synthetic fibers blending, intertexture, take and fabrics for industrial use for all kinds of.High tenacity staple fibre strength is higher, can extensively answer
For industrial products such as tire cord, conveyer belts.The characteristics of viscose rayon has natural fiber and chemical fibre concurrently, with science and technology
Progressive various functions viscose rayon be continuously developed successfully, so as to widen the application of viscose rayon significantly.Function
Property viscose rayon species it is very many, such as FRC, antibacterial viscose fiber, uvioresistant viscose rayon, deodorization viscose rayon,
Far-infrared viscose fiber fiber, phase change fiber, conductive viscose fiber, high adsorption viscose rayon, anion viscose fibre, ion exchange
Viscose rayon, aromatic viscose fiber, graphite fibre etc..Viscose rayon both can in process of production be adopted as chemical fibre
New technology gives fiber new performance, it is also possible to include that chemical modification or grafting etc. are processed by postfinishing process new to prepare
Functional viscose fiber.Thus viscose rayon is substantially the fiber that functionalization is easiest in all multifilaments.
But as regenerated celulose fibre, viscose rayon have sucting wet air permeability similar to cotton fiber, comfortableness and
Biocompatibility, thus it is widely used in the fields such as textile garment, health care and adsorbing material.Equally, viscose rayon
It is the ideal place of breed bacteria and funguses.For at present, the antibiotic finish of many concern viscose rayon products of major part research is led to
Cross carries out antimicrobial treatment to product, and because finishing agent acts only on surface, antimicrobial particle is unable to active adsorption to viscose rayon
Portion, is easily come off by time passage generation antimicrobial particle and is discharged too early, causes product anti-microbial property to decline, it is impossible to meet existing product
The demand of product.
The content of the invention
The technical problem to be solved：Poor, the antibacterial for the current antibacterial viscose fiber Durability of antimicrobial effect for preparing
Particle is easy to fall off or problem of too early release, there is provided a kind of by by Formica fusca antibacterial peptide and the compound platinum ion of needle antibacterial peptide,
Antimicrobial particle is set to infiltrate into inside viscose rayon by dipping, the method for extending antibacterial viscose fiber antibacterial duration, the present invention is logical
Cross to be dried Formica fusca with Folium Pini and mill, alcohol extraction antibacterial concentrated solution, then platinum colloidal sol is carried with platinum nitrate and the compound preparation of Tanabe Seiyoku,
Subsequently viscose rayon is impregnated to carrying in platinum colloidal sol, stands and make antibacterial ion to be adsorbed to viscose rayon surface, be effectively improved viscous
Glue fiber antimicrobial lifetime, has broad application prospects.
