Description
Technical field
The present invention relates to a kind of method of synthesis modification polyvinyl chloride, it is especially a kind of with sterilization, bacteriostasis it is poly-
The manufacturing method of vinyl chloride guanidine hydrochloride anti-bacterial fibre.
Background technique
As the improvement of people's living standards, requirement of the people to clothes is from initial endurable, solid gradually to beautiful, easypro
Diversified development is accommodated, while pursuing the high product of personalized class.In recent years, with the continuous development of textile technology and antibacterial
The appearance of fiber, the dress ornament with antibiotic property, bactericidal properties are particularly subject to extensive concern and the welcome of people.Anti-bacterial fibre can wide model
Manufacture mouth is applied also for especially suitable for old, pregnant and lying-in women and infant clothing for home textile articles, underwear, sport shirt etc.
The clothes that the clothes and special occasions that the sheet and gasket of cover, prevention patient's bedsore, hospital doctor and patient are worn use.
Anti-bacterial fibre can be divided into following a few classes: one kind is plants antimicrobial fiber, 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 made to be very limited；Another kind of artificial anti-bacterial fibre passes through surface coating, co-blended spinning, fiber
The anti-bacterial fibre that the chemical methodes such as physical methods and copolymerization, graft modification such as surface treatment obtain.Such as patent document
Disinfectant is used as using silver in CN102392347A, this method is at high cost, and production is cumbersome, in metallic fiber and sweat or air
Reaction of Salmon-Saxl generates sulfide precipitation, is easy allergy with skin contact, can seriously be poisoned.
It, can be with by using the anti-biotic material for having positive charge since most bacterium and virus all have negative electrical charge
Absorption and barrier action are generated to bacterium and virus, and further suppress and kill its activity.
Summary of the invention
The invention aims to provide, cheap one kind, efficient sterilizing non-stimulated to skin, bactericidal effect is held simultaneously
The synthetic method of long polyvinyl chloride guanidine hydrochloride and anti-bacterial fibre.
The technical scheme is that
The manufacturing method of polyvinyl chloride guanidine hydrochloride anti-bacterial fibre, includes the following steps,
Step 1, the preparation of polyvinyl chloride bead,
By polyvinyl chloride powder, cyclohexanone, Ca is added3(PO4)2It is in fine particle to polyvinyl chloride after stir about 0.5h
When, stop stirring, filter, washing, ethyl alcohol is washed, dried to get milky polyvinyl chloride bead；
Step 2, the preparation of polyvinyl chloride amine
It weighs polyvinyl chloride bead and mixing sweller is added, after being swollen about 0.5h, ammonium salt heating is added, stirring, reflux is about
It is cooling after 8h, it filters, washing, alkali cleaning, ethyl alcohol is washed, and is dried, and the polyvinyl chloride that part amino replaces is made；
Reaction equation are as follows:
Step 3, the synthesis of polyvinyl chloride guanidine hydrochloride
It weighs polyvinyl chloride amine and excessive hydrochloric acid guanidine is added, heat 150-160 DEG C, react 4 hours, it is cooling, wash to obtain polychlorostyrene
Ethylene 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 present invention are:
1, herein described anti-bacterial fibre effectively can kill or reduce bacterium on fabric, virus, can be widely used in doctor
It learns and in daily life, is such as used for old man, child, maternity dress, manufacture mask, deodorization diaper, the sheet for preventing patient's bedsore
And gasket, the clothes that the clothes and special occasions worn there are also hospital doctor and patient use.
2, the guanidine hydrochloride with positive charge is grafted 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 purpose that bactericidal effect is lasting.
