A kind of preparation method of antibacterial hospital gauzeTechnical field
The present invention relates to the preparation method of a kind of chitin blend fibre, particularly relate to a kind of method by chitin fiber with cotton fiber blending.
Background technology
At present, China's textile consumer need has been turned to by living type consumption enjoys type consumption, gradually become main body of consumption from textile production base, people grow with each passing day for the demand of high-quality textile, and the demand of the protein fibre especially to human body high quality fiber with good affinity is being continuously increased equally.Conventional traditional natural protein fibre includes lint class and silk fiber.This two types of fibers is good with comfortableness, good luster, elegant style etc. are outstanding wearability and favored by consumer, but its resource-constrained, price are high, only account for about 3.5% in the textile fabric total quantity consumed of the whole world.Therefore, people have started the research and development of azlon very early.At present, the azlon realizing industrialization including soybean fiber and milk protein fiber etc. is not soybean protein regenerated fiber or the milk protein regenerated fiber of 100%, wherein containing the synthetic high polymer of about 55～75%, these fibers are difficult to the requirement meeting high-end textile for fiber quality.
Gauze is the necessity in our daily life, the so selective Chinese medicine material that adds in gauze process is mixed with organic cotton, protein fibre, bamboo fibre, anti-biotic material, jade powder, can make existing gauze not only having that conventional antimicrobial is antibacterial, also have outside cleaning function and improve blood circulation, enhance metabolism, dispelling fatigue, inducing resuscitation brain tonic, the effect of light speckles, beautification and white, and prepare gauze feel smooth, submissive pleasant, moisture absorption is breathed freely, and more comfort, is the antibacterial mite-removing hospital gauze of a kind of brand-new type.China is the first ancestor of the traditional Chinese medical science, with a long history, medicinal raw material abundant species, scope of selecting material is vast, and because of Chinese medicine there is curative effect property obvious, safe and non-stimulating, toxic and side effect has a extensive future outside Chinese and Western, its level of consumption is the most more easily accepted by the common people, and the combination therefore using medium-height grass raw material and gauze to prepare material has good prospect really.
Summary of the invention
The technical problem to be solved is, it is provided that a kind of pliability and biocidal property is good is formed gauze goods by prepared by modifying agent by chitin fiber and cotton fiber blending.Use this gauze except having that conventional antimicrobial is antibacterial, also have in addition to cleaning function and improve blood circulation, enhance metabolism, dispelling fatigue, the effect of inducing resuscitation brain tonic, and the gauze feel prepared is smooth, submissive pleasant, moisture absorption is breathed freely, and more comfort, is the antibacterial mite-removing hospital gauze of a kind of brand-new type.
The technology contents of the present invention is: the preparation method of a kind of antibacterial hospital gauze, the medical raw material of this gauze is to be formed with cotton fiber blending by chitin fiber, described chitin fiber is chitin fiber with the weight ratio of cotton fiber material: cotton fiber=35-45:55-65, and raw material mixes the preparation of yarn and comprises the following steps:
(1) chitin pretreatment:
Selected 500 public-1000 public Zhi Youzhi chitin fibers, are divided into rickle after chitin fiber is uniformly torn into fritter；
(2) chitin modification processes:
First, modification liquid is sprayed on the chitin fiber banked up, modification 12-24 hour；Described modification liquid is made up of each raw material of following weight percentage: decis 2-3%, alkyl phosphate 5-8%, glycerine 2-4%, ester based quaternary ammonium salt 0.1-0.3%, titanate coupling agent 5-7%, remaining as water；The modified liquid measure of modification is the 6-10% of chitin fiber weight every time；
Then, chitin fiber is sent in vaporium, steam 35-55 minute；
(3) chitin after modification is mixed with groove raft on the cotton fiber of aforementioned proportion；
(4) carry out comb and parallel cotton fibers prior to spinning, combing, drafting according to conventional processes, spin rove, spin spun yarn, winder, doubling, double twisting and i.e. obtain raw material and mix yarn；
The preparation method of described hospital gauze comprises the following steps:
(1) raw material obtained above is mixed weaving yarns and become gauze grey cloth；
(2) moving back in the hot water storgae boiling rinsing combination machine by the grey cloth woven immersion, bath raio is 1:25-30, first cleans 20-30 minute with the water of 95-100 DEG C, reducing temperature 5-10 DEG C again, water cleans 4-8 minute, then adds finishing auxiliaries in water, adjust aqueous temperature and be 65-75 DEG C, clean 40-50 minute；Described finishing auxiliaries is prepared from the following raw materials in parts by weight: carry silver organo-sol 10-15, epoxychloropropane 3-6, antibacterial microcapsule 7-9, ethylene glycol 12-14, polyhexamethylene guanide 0.4-0.7, sodium citrate 2.1-2.6, alkyl phosphate 5-7, AEO 6-8, nano silicon 2-3；The antimicrobial component of described antibacterial microcapsule is based on Econazole family macromolecule compound and pyrethroid compounds；
(3) it is that 90-100 DEG C of clear water boils 30-40 minute by above-mentioned grey cloth temperature again, adds hydrophilic softening agent, cellulase, polyacrylamide and magnesium sulfate, continue at the temperature disclosed above to boil 10-20 minute；And go out cloth, it is dehydrated 20-25 minute with dewaterer；
(4) drying and shaping: by the grey cloth that has been dehydrated through scutcher open-width, then drying machine drying and processing 18-25 minute at 110-130 DEG C, obtains described hospital gauze.
Preferably, described spins in process of roving, and technological parameter is: roving twist factor is 100-120, rove ingot speed is that 600-700 turns/min.
Preferably, described spins in spinning process, and technological parameter is: yarn twist factor is 800-1000, spun yarn spindle speed is that 8000-10000 turns/min.
Beneficial effects of the present invention: alkyl phosphate can produce crosslinked action to chitin fiber, and cross-linking process is efficient, nontoxic；Epoxychloropropane can react with the amino in cellulosic molecule in the case of alkali is as catalyst, produces crosslinked action.
Advantage for present invention is: the present invention produce the low cost of antibacterial hospital gauze and production technology simple with efficiently；The chitin blend fibre not only tensile mechanical properties that the present invention produces is good, and can be degradable, good biocompatibility, can be applicable to the field such as manufacture and biology, medicine, organizational project of high-quality textile；Use its gauze prepared can the most not only having that conventional antimicrobial is antibacterial, also have outside cleaning function and improve blood circulation, enhance metabolism, dispelling fatigue, the effect of inducing resuscitation brain tonic, and prepare gauze feel smooth, submissive pleasant, moisture absorption breathe freely, more comfort, is the antibacterial except mite hospital gauze of a kind of brand-new type.
