Description
Technical field
The present invention relates to a kind of textiles and preparation method thereof, relate to antibiotic-mould proof textile fabric and preparation method thereof specifically.
Background technology
Textiles can absorb effluents such as the sweat, sebum of human secretory, under the suitable environment of temperature and humidity, the microorganism that resides on the textiles can breed in a large number, decompose human secretion, generation ammonia etc. has the material of peculiar smell, or generates bacterial plaque on fabric, so that in dress or application process, human body is produced discomfort or harmful effect, textiles is produced go mouldy, embrittlement even rotten.Along with the development of society and the raising of people's living standard, produced the new market demand, the consumer wishes that textiles has antibacterial functions, to satisfy the comfortable living needs of civilization.In textiles, natural fabric is better and comfortable and easy to wear than synthetic fiber moisture absorbing and sweat releasing performance, and underclothes such as people's underwear, socks, towel, the sheet overwhelming majority adopts natural fiber material, so natural fiber material becomes the main product of antibiotic fabric.Antibiotic fabric is meant under the prerequisite that does not change sense organ of fabric own or physical and chemical character (as intensity, water imbibition, feel, aberration), use various antiseptics that fabric is carried out antibiotic processing, it is rotten not only to make fibrous material itself can resist microbial decomposition, also can make attached to microorganism devitalization on the fabric or excessive multiplication not, improved the quality of textiles and consumer's quality of life, made antibiotic fabric also enter household consumption product ranks.
Antibacterial product in the market is to adopt three kinds of methods to produce basically: the one, and antiseptic is added make anti-bacterial fibre in the spinning material earlier, make various antibacterial fabrics then.This method antibacterial effect is lasting, and washability is good, but with high content of technology, and difficulty is big, and it is wide to relate to the field, antiseptic is required high; Be commonly used to produce synthetic fibrid series products.The 2nd, behind fabric printing, add antiseptic (often being called as antibacterial finishing agent) in the arrangement process, make various antibacterial fabrics then.This method processed is comparatively simple, and washability and antibacterial effect persistence are relatively poor.The 3rd, antiseptic is joined make anti-bacterial fibre in the spinning material earlier, behind fabric printing, add antibacterial finishing agent in the arrangement process again, make various antibacterial fabrics then, this method is only used in the specialities with high anti-microbial property requirement, has limited the scope of application.
Natural fabric (comprising cotton, fiber crops, hair, silk etc.) material is owing to be difficult to reach by fibre modification the effect of antibacterial deodourizing, and up to the present, the antibacterial deodourizing technology of natural fibre products still arrangement later on is main.Antiseptic commonly used mainly contains inorganic, organic, natural and polymer antibacterial agent four big classes.Inorganic antiseptic mostly is the heavy metal ion antiseptic, wherein again based on silver ion and compound thereof.Inorganic antiseptic belongs to the dissolution type antiseptic, its antibiotic mechanism is the antibiotic mechanism of ion slowly-releasing, in use promptly, the antibacterial activity ion slowly discharges, combine by metal ion activity destruction bacterial cell membrane or with the groups such as sulfydryl of bacterial enzyme albumen, the activity of destructive enzyme, thereby performance antibacterial action.The antiseptic that these heavy metal compositions are made has the anxiety of the heavy metal pollution that causes textiles.The heavy metal that contains on the antibacterial fabric, majority belongs to free state, though its stripping property is not high, prolonged application may work the mischief to human body.Because it can discharge also and contact skin from fiber surface, infiltrating human body by skin pore accumulates in liver, kidney, the heart, brain and the bone in human body, when the heavy metal in the involved organs runs up to certain degree, just can cause irreversible damage to healthy body.So Hg, Ag, harmful heavy metal ion pair human bodies such as Cu have stronger damaging effect.Also have some inorganic antiseptics, though good antibacterial performance is arranged, because of not forming firm bonding state with fiber, not water-fast washing eliminated gradually.
Organic antibacterial agent be mainly compounds such as quaternary ammonium salt, alcohols, halogen amine, biguanides, have instant effect, the characteristics that sterilization can be strong are wherein again based on quaternary ammonium salt.The quaternary ammonium salt chemism is lower, exists with free state basically during application, and toxicity is bigger, and excitant is also stronger.It is applied on the textiles as antiseptic is dissolution type, and heat resistance is relatively poor, easily migration, and easy wash-out, and also easily in human body surface enrichment gradually, the long-term use easily produces pathology, generation microorganism anti-(resisting) property of medicine.Patent [89104903] discloses a kind of quaternary ammonium salt antiseptic WS-8810.This antiseptic has epoxy isoreactivity group, can with active hydrogen group reactions such as hydroxyl in the fiber, amino, its preparation process complexity, and added the raw material that a large amount of formaldehyde, benzyl chloride, benzyl amine etc. have high toxic and side effect in the preparation process, if purification process is incomplete, can bring a lot of toxic and side effects.And also trouble relatively of finishing technique, need carry out at high temperature, unavoidably the performance to fiber itself produces certain adverse effect.In addition, WS-8810 is yellow to pale brown look thick liquid, easily makes the textiles variable color, and influences the color and luster of textiles itself.
Natural antibacterial agent comes from natural extract, and as [Chinese patents 200410046060] such as shitosans, its main antibiotic mechanism is considered to similar with the organic quaternary ammonium salt class, but effect is not so good as organic antibacterial agent, and product is still immature.Polymer antibacterial agent is that people carry out MOLECULE DESIGN according to the antibiotic mechanism of organic antibacterial agent and natural polymer antiseptic, combine the characteristics of organic antibacterial agent and natural polymer antiseptic synthetic, mainly comprise the macromolecule of synthetic pyridine type main chain, the polyolefine material and the modification PS-polystyrene hydantoin (POLY1) of band pyridine side group, be in the research starting stage at present.
Though (be called for short: DC-5700) natural textile is put in order report to some extent, the bio-enzyme immobilization technology has adopted H to bio-enzyme immobilization technology and 3-(trimethoxy monosilane) propyl-dimethyl octadecyl ammonium chloride
2O
