Along with improving constantly of scientific and technological progress development and people's living standard, the health care consciousness of people to self strengthens day by day, and the antibacterial fabric with durability more and more causes the attention of people.It is predicted, various durability antibacterial fabric will become hot item, and therefore R and D antibacterial fabric will become again a focus.
Microorganism, namely bacterium, mould, yeast, almost exist everywhere.Most microorganism is harmless to the mankind, or even useful and required, but also has 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 cannot visually see.
Textiles and human lives closely related, be one of medium of directly or indirectly propagating of microorganism.At the upper part of the body of health, per square centimeter on average has various microorganism 50-5000, if condition is suitable for, certain micro-organisms can produce abnormal breeding, even useful microorganism also may morph.The grain of the cotton in natural fabric, hair inherently microorganism, the breeding of microorganism can cause some disease or makes skin produce abnormal stimulation and cause and do not feel soon.The excreta such as sweat, sebum of human secretory is attached on skin, easily causes growing and breeding of microorganism, thus makes underskirt produce foul smell, and socks make pin bring out into the ringworm of the foot, and baby's diaper causes macula etc.The clothes, bedding etc. of the doctor served at a hospital, nurse and patient, because antibacterial and not antiviral meeting causes the cross infection of bacterium and virus.Textiles, in transport storage, under the condition that temperature and humidity is suitable or because of reasons such as contaminations, also can cause the breeding of microorganism, breeding as mould forms enzyme spot, make fabric Local Coloring or variable color, even produce biological explanation and occur tendering, use value and sanitation performance sustain damage.Before 4000, Egyptian is just with the textiles parcel mummy of certain prescription of dipping.In the World War I, Danish scientist finds that poison gas makes the wound of victim suppurate, and has from then on started the research work of bactericide.In World War II, Reichsweshr once with quaternary ammonium salt antiseptic process military uniform, greatly reduced the infection rate of the wounded.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 developing stage transition, durability and the arrangement style of the hygienic finishing eighties in last century are further improved, and pay much attention to the exploitation of hygienic finishing textiles both at home and abroad.The nineties, antibacterial and deodorant textiles obtained fast development, be the function textile that main textiles develops into anti-bacterial fibre and hygienic finishing and develops simultaneously from Final finishing, the antibiotic property of fabric, security and washing resistance improve further, and occur the textiles of the sanitation performance such as smelly eliminating, insect protected.
As everyone knows, survive various microorganism in the environment of human lives, on the skin of only upper half of human body, every square metre just has 50-5000 microorganism, wherein some is useful to human body, or even it is 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 bacterium, they can go out the volatile compounds frowzy such as various lower fatty acid and amine by catalyze metabolic decomposition product, add the smell that the secretion of bacterium itself rots with its dead bones of the body, 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 disease as venereal disease, skin disease etc., unhealthful.Therefore people always by every means kill harmful microorganism.
But traditional cotton, wash raw material when for clothing of spring and summer fabric, have the shortcoming that there is perspire poor effect, antibacterial effect is poor.Bamboo fibre is a kind of emerging natural and fiber of 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 features are all better than cotton goods, and importantly it also has natural antibacterial in addition.
Along with people's uphold nature, the demand of back to nature and the continuous enhancing of environmental protection consciousness, green health textiles is subject to the favor of people day by day.Bamboo fibre is a kind of natural high polymer that the bamboo known by people processes as a kind of cellulose fibre.Bamboo fibre because of its macromolecular special construction, and has and well restrains the health care such as bacterial growth, adsorb peculiar smell, and hygroscopic vapor transmission, biodegradable, is described as the green fiber of new century.
Lyocell bamboo fiber, also known as solvent method bamboo fiber, is a kind of regenerated bamboo fiber adopting Lyocell technique to spin for raw material with bamboo cellulose pulp.
The common preparation technology of Lyocell bamboo fiber is: bamboo cellulose pulp is directly dissolved in the aqueous solution of N-methylmorpholine-N-oxide (being called for short NMMO), and prepares regenerated celulose fibre by wet spinning.This friendly process has the features such as abundant raw material, simple, the advanced environmental protection of production procedure, good product performance.Be expected to replace with serious pollution traditional fibre cellulose fiber production technology and adhering process gradually.Solvent method bamboo fiber belongs to the one 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, the discarded object of production Lyocell bamboo fiber can natural degradation, amine oxide solvent in production process can 99.5% recycling, and free from environmental pollution.
