Description
Technical field
The present invention relates to a kind of method of synthesis modification polyvinyl chloride, especially it is a kind of have sterilization, bacteriostasis it is poly-
The manufacture method of vinyl chloride guanidine hydrochloride anti-bacterial fibre.
Background technology
As the improvement of people's living standards, requirement of the people to clothes is from initial endurable, solid gradually to attractive in appearance, easypro
Diversified development is accommodated, while pursuing the high product of personalized class.In recent years, continuing to develop and antibacterial with textile technology
The appearance of fiber, the dress ornament with antibiotic property, bactericidal properties is particularly subject to extensive concern and the welcome of people.Anti-bacterial fibre can wide model
For home textile articles for use, underwear, sport shirt etc., old, pregnant and lying-in women and infant clothing are particularly suitable for use in, applies also for manufacturing mouth
The sheet and pad of cover, prevention patient's bedsore, the clothes that the clothes and special occasions that hospital doctor and patient are worn are used.
Anti-bacterial fibre can be divided into following a few classes：One class is plants antimicrobial fiber, and such as patent document CN101694019A is public
The bamboo fibre opened, because of the special construction of its macromolecular, and has and restrains the healthcare functions such as bacterial growth, absorption peculiar smell, but fine
Low-intensity is tieed up, its application is very limited；Another kind of artificial anti-bacterial fibre, i.e., coated, co-blended spinning, fiber by surface
The anti-bacterial fibre that the chemical methodes such as physical method and copolymerization, graft modification such as surface treatment are obtained.Such as patent document
Using silver as disinfectant in CN102392347A, this method cost is high, makes cumbersome, in metallic fiber and sweat or air
Reaction of Salmon-Saxl, generates sulfide precipitation, easy allergy is contacted with skin, can be seriously poisoned.
, can be with by using the anti-biotic material with positive charge because most bacterium and virus all carry negative electrical charge
Absorption and iris action are produced to bacterium and virus, and further suppresses and kills its activity.
The content of the invention
The invention aims to provide a kind of cheap, non-stimulated to skin, efficient sterilizing, while bactericidal effect is held
Long polyvinyl chloride guanidine hydrochloride and the synthetic method of anti-bacterial fibre.
The technical scheme is that：

When, stop stirring, suction filtration, washing, ethanol is washed, dried, and produces milky polyvinyl chloride bead；
Step 2, the preparation of polyvinyl chloride amine
Weigh polyvinyl chloride bead and add mixing sweller, be swelled after about 0.5h, add ammonium salt heating, stir, backflow is about
After 8h, cooling, suction filtration, washing, alkali cleaning, ethanol is washed, and is dried, and the polyvinyl chloride of part amino substitution is made；
Reaction equation is：
Step 3, the synthesis of polyvinyl chloride guanidine hydrochloride
Weigh polyvinyl chloride amine and add excessive hydrochloric acid guanidine, heat 150-160 DEG C, react 4 hours, polychlorostyrene is washed to obtain in cooling
Ethene guanidine hydrochloride master batch；
Step 4,
By the direct wire drawing of polyvinyl chloride guanidine hydrochloride master batch in step 3, the anti-bacterial fibre of strong antibacterial is prepared.
The beneficial effects of the invention are as follows：
1st, herein described anti-bacterial fibre effectively can kill or reduce bacterium on fabric, virus, can be widely used in doctor
Learn and in daily life, be such as used for old man, child, maternity dress, manufacture mouth mask, deodorization diaper, the sheet for preventing patient's bedsore
And pad, the clothes that the clothes and special occasions that also hospital doctor and patient are worn are used.
2nd, the guanidine hydrochloride with positive charge is grafted onto on PVC macromolecular long-chain by the present invention, utilizes guanidine compound
Excellent bactericidal property reach efficient sterilizing, it is cheap, it is non-stimulated to skin, while the lasting purpose of bactericidal effect.
