Antibiotic bamboo cotton blended spinning face fabric
Technical field
The present invention relates to a kind of fabric, relate in particular to a kind of antibiotic bamboo cotton blended spinning face fabric.
Background technology
Along with improving constantly of scientific and technological progress development and people's living standard, people strengthen day by day to the health care consciousness of self, and the antibacterial fabric with durability more and more causes people's attention.It is predicted, various durability antibacterial fabrics will become hot item, so the R and D antibacterial fabric will become again a focus.
Microorganism, bacterium, mould, yeast, almost exist everywhere.Most microorganisms are harmless to the mankind, or even useful and essential, but also have the fraction microorganism can cause the mankind and vegeto-animal disease, and these can cause the microorganism of the mankind and animals and plants disease to be called pathogenic microorganism.Bacterium is one of important kind in microorganism, and its individuality is small, and the mankind can't with the naked eye see.
Textiles and human lives are closely related, are one of direct or indirect media of propagating of microorganism.At the upper part of the body of health, average every square centimeter has various microorganism 50-5000, if condition is suitable, certain micro-organisms can produce abnormal breeding, even useful microorganism also may morph.Cotton in natural fabric, untrimmed book body are exactly the grain of microorganism, and the breeding of microorganism can cause some disease or make skin produce abnormal stimulation and do not cause sensation soon.The excretas such as the sweat of human secretory, sebum are attached on skin, easily cause growing and breeding of microorganism, thereby make underskirt produce foul smell, and socks make pin bring out into the ringworm of the foot, and baby's diaper causes macula etc.The doctor who serves at a hospital, nurse and patient's clothes, bedding etc., because antibiotic and not antiviral meeting causes bacterium and viral cross infection.Textiles, in the transportation storage, under suitable condition or because of reasons such as contaminations, also can cause the breeding of microorganism in temperature and humidity, breeding formation enzyme spot as mould, make fabric Local Coloring or variable color, even the biological explanation generation of generation is tendering, and use value and sanitation performance sustain damage.Before 4000, the Egyptian just wraps up mummy with the textiles of certain prescription of dipping.In the World War I, the Denmark scientist finds that poison gas can not suppurate victim's wound, has from then on started the research work of bactericide.In World War II, Reichsweshr once processed military uniform with quaternary ammonium salt antiseptic, greatly reduced the wounded's infection rate.1955-1965 is the formation stages of antibacterial fabric, and the antibacterial fabric of " Sanitized " by name is put on market; 1966-1976 is the development phase, and the organo-metallic compound of stanniferous, copper, zinc, mercury and quinones and sulfur-containing compound are used for doing fabric antimicrobial finishing agent.After 1976, to the developing stage transition, the durability of the hygienic finishing eighties in last century and arrangement style are further improved, and pay much attention to the exploitation of hygienic finishing textiles both at home and abroad.The nineties, the antibacterial deodourizing textiles obtained fast development, from arrangement be that main textiles develops into the function textile that anti-bacterial fibre and hygienic finishing develop simultaneously, the antibiotic property of fabric, security and washing resistance further improve, and the textiles of the sanitation performances such as smelly eliminating, insect protected occurs.
As everyone knows, various microorganisms are surviving in human lives's environment, only on the skin of upper half of human body every square metre 50-5000 microorganism just arranged, wherein some is useful to human body, or even indispensable, but also there are many microorganisms to impair health, they can survive in people's fabric used in everyday, as socks, underwear, underpants, cotton-wadded quilt, sheet, towel etc., in the environment of warm moist, these microorganisms are with the sweat of human secretory, grease, the decomposed substance of scurf or fabric itself is bred rapidly as nutriment, form a large amount of harmful bacteriums, they can decomposite the volatile compounds frowzy such as various lower fatty acids and amine by the catalysis metabolite, add secretion and the rotten smell of its dead bones of the body of bacterium itself, discharge nauseating bad odor, more seriously they also can produce abnormal stimulation to human body skin, bring out various disease of skin, even can propagate various diseases as venereal disease, skin disease etc., unhealthful.Therefore people always by every means kill harmful microorganism.
Yet traditional cotton, wash raw material for the clothing of spring and summer fabric time, the shortcoming that has the perspire poor effect is arranged, antibacterial effect is poor.Bamboo fibre is a kind of fiber of emerging natural and environmental protection, and its base stock comes from the evergreen plant bamboo of the Nature.Bamboo fibre has hygroscopicity, gas permeability and drapability, and these characteristics all are better than cotton goods, and importantly it also has natural antibacterial in addition.
Along with people's uphold nature, the continuous enhancing of the demand of back to nature and environmental protection consciousness, the green health textiles is subject to people's favor day by day.Bamboo fibre is a kind of natural high polymer processed by the known bamboo of people as a kind of cellulose fibre.Bamboo fibre is because of its macromolecular special construction, and has the health cares such as good supression bacterial growth, absorption peculiar smell, and hygroscopic vapor transmission, biodegradable, is described as the green fiber of new century.
The Lyocell bamboo fibre, claim again the solvent method bamboo fibre, is a kind of regenerated bamboo fiber that the bamboo cellulose pulp adopts Lyocell technique spinning to form as raw material of take.
The common preparation technology of Lyocell bamboo fibre is: the bamboo cellulose pulp directly is dissolved in N-methylmorpholine-N-oxide aqueous solution of (being called for short NMMO), and prepares regenerated celulose fibre by wet spinning.This friendly process has the characteristics such as abundant raw material, simple, the advanced environmental protection of production procedure, good product performance.Being expected to replace gradually with serious pollution traditional fibre cellulose fiber production technology is adhering process.The solvent method bamboo fibre belongs to a kind of of Lyocell fiber, is described as the green fiber of 21 century.Application for a patent for invention prospectus CN101694019A discloses solvent method high-wet-modulus bamboo fiber and preparation method thereof, but produce the discarded object natural degradation of Lyocell bamboo fibre, amine oxide solvent in production process can 99.5% recycling, and free from environmental pollution.
