Description
Technical field
The present invention relates to cellulose fibre fields, relate in particular to a kind of anti-by the chitosan of substrate of cellulose fibre
The preparation process of bacterium fiber.
Background technique
Since the new century, with the improvement of living standards, requirement of the people to quality of life also increasingly increases, environment has been defended
Raw and health is also increasingly paid attention to.Various bacteriums have been covered with it in the environment that we live, some in these bacteriums
It constitutes a serious threat to people's health.In the growth, breeding, communication process of germ, textile act as one it is important
Role, and the dirts such as sweat, sebum of human body generation can adhere on the textile, it is easier to breed germ.Therefore, it is weaving
Antimicrobial technology is applied on product, while guaranteeing beautiful, comfortable, effectively reduces harm of the germ to human body, also to guarantee people
Health it is significant.
Natural antibacterial material is to refine and obtain out of plant or animal body, while killing germ to human body almost without
Side effect.Chitin is a kind of natural materials extracted from Carapax Eriocheir sinensis, shrimp shell, and chitosan is deacetylated one obtained of chitin
Kind of the nontoxic natural polymer of alkalinity, has a good biocompatibility, biological degradability, and to skin without allergy, non-stimulated
Effect.With a large amount of free amino in the molecular structure of chitosan（-NH2）, contain unshared electron pair on N atom, hold very much
A H proton is easily combined ,-NH2 is protonated as-NH3+, thus, chitosan becomes positively charged lotus.The cell of bacterium is negatively charged,
When interacting with the positive charge on chitosan, the permeability of cell is changed, thin film is formed in cell surface, hinders thin
Bacterium obtains nutriment, to interfere cell normal growth, breeding.Also, the amino on chitosan（-NH2）And hydroxyl（-OH）
It can be with metallic element necessary to some bacterial growths（Such as zinc）Chelating, has blocked the intake of cytotrophy substance, to reach
The purpose of antibacterial is complexed.
Cellulose fibre is a kind of common textile fiber.Cellulose fibre is with cellulose one kind as main component
Linear macromolecule polymer is divided into native cellulose fibre, such as cotton, fiber crops and regenerated celulose fibre, such as viscose rayon, copper
Ammonia fiber etc., the structure of cellulose are to be formed by D- glucopyra saccharide ring with β-Isosorbide-5-Nitrae glycosidic bond links.Cellulose macromolecule surface
It is relatively flat, and multiple activity hydroxies are had on glucose ring, this structure and form of cellulose make cellulose fibre
Hygroscopicity and dyeability it is preferable, also help and fiber be modified.
Chinese patent application notification number " CN101838347A " disclose a kind of alkali soluble chitosan ramification preparation and
Application in viscose rayon manufacture, the alkali soluble chitosan ramification are chitins by carboxy methylation, deacetylated
O-CMC obtained, and O-CMC is demonstrated with antibiotic property；Then by O-CMC with
Viscose rayon, which is blended, carries out spinning, and resulting textile equally has good antibacterial property energy.The patent alkali solubility chitosan spreads out
Biology/viscose glue anti-bacterial fibre has many advantages, such as that natural, good biocompatibility, stability are high, antibacterial effect is obvious, cost is relatively low,
Thus it can speculate that the product can be used for manufacturing underskirt trousers, footgear, bedding, gauze etc..But the carboxylic of chitosan in the patent
Methylation influences chemical reagent toxicity that is very big, and using during preparing carboxymethyl chitosan to anti-microbial property
Larger, security risk is serious.
Chinese patent application notification number " CN106905438A " disclose a kind of chitosan quaternary ammonium salt antibacterial cellulose and its
Preparation method.This method passes through the antibacterial cellulose of amidation process grafted chitosan quaternary ammonium salt mainly using cellulose as matrix；
This method contains the quaternary ammonium salt presoma compared with polyamino using chemical graft, and then quaternized technology, obtains on the surface of the material
Stablize effective antibacterial group, step is simple, and low in cost, reaction efficiency is high, there is biodegradability, biocompatibility,
Environmentally friendly, prepared antibacterial antiplaque agent robust consistent all has staphylococcus aureus and Escherichia coli excellent
Different anti-microbial property, and use can be stirred by antibacterial agent prepared by the method for the present invention, to cellulosic matrix without destruction.
But chitosan quaternary ammonium salt has slight cytotoxicity.
Chinese patent application notification number " CN104532571A " discloses a kind of preparation process of chitosan oligosaccharide modification cotton fiber,
The invention first prepares pretreatment cotton fiber using chitosan oligosaccharide, cotton fiber as raw material；It is reacted again with epoxychloropropane with chitosan oligosaccharide,
Prepare hydroxypropyl chitosan oligosaccharide；Then, successively with hydroxypropyl chitosan oligosaccharide and bisglycidyl ether respectively to pretreatment cotton fiber into
Row etherificate modification, prepares grafting chamber propyl chitosan oligosaccharide cotton fiber product.The invention is mild with reaction condition, specificity is strong,
Easy to operate, the features such as cost is relatively low, easy to promote and utilize.But in the patent with chitosan oligosaccharide make antibacterial agent, epoxychloropropane and
Bisglycidyl ether makees crosslinking agent crafted cotton fibers, prepares anti-bacterial fibre, and it is hardened that the crosslinking agent used will cause fiber.
Summary of the invention
It is an object of the invention to solve the above-mentioned problems in the prior art, one kind is provided using cellulose fibre as base
The preparation process of the chitosan anti-bacteria fiber of material.With Covalent bonding together between chitosan and cellulose fibre of the present invention, in conjunction with jail
Solid, stablize, good anti-bacterial effect；And manufacture craft is simple, easy to operate, and reaction condition is mild, safe, without the shell of reaction
Glycan can also be reused, and production cost is low.
