Description
Technical field：
The present invention relates to field of medical materials, are specifically related to a kind of preparation method of high-performance medical textile material.
Background technology：
Since 21st century, the Nonwovens In Technology in China obtains full progress, wherein medical non-woven fabrics
Production and application development it is especially prominent.But the medical textile in China there are still quality unqualified, qualification authentication blank etc.
Problem.Develop frequency in order to hold China's medical textile again, and study its developing direction, I makes this research.
Textile material is applied to medical field and starts to walk very early, and ancient Egyptian just understands flax with natural glue bond before 4000
Yarn is sewed up a wound, so that wound can heal in time, mummy is wrapped up with the fabric of medicinal plant treatment, to prevent it from rotting.
Also early useful flaxen fiber makees suture in the history records of ancient Chinese, the record bound up a wound and stopped blooding with cotton.Textile material exists
Medically there is very useful value.Tensile properties use the natural fibers such as cotton, hair, fiber crops earliest, with the development of science and technology,
Synthetic fibers are largely used again.Especially make encouraging progress in recent years to the research of biodegradable fiber, degradableization
It learns fiber and chitin fiber starts the concern for causing people.At the same time, the popularization of medical non-woven cloth, makes chemical fibre
Application range further expands, and the development of medical textile material also more and more shows huge vigor.
Medical textile is the fabrics for industrial use based on fiber and fabric using medical application as characteristic.Medical spinning
Fabric must it is nontoxic, without allergy, non-carcinogenesis, do not play any variation of physically or chemically performance in disinfection.Most common day
Right fiber is cotton, silk and regenerated fiber viscose rayon yarn, they be widely used as Nonimplantation material (wound dressing, bandage etc.) and
Health care product (bedding, clothing, diaper, sanitary napkin, wipe etc.)；The chemical fibre being often used includes polyester, gathers
Amide, polytetrafluoroethylene (PTFE) (PTFE), polypropylene, carbon fiber and glass fibre.Compared with the woven medical textile of traditional pure cotton,
Medical non-woven fabric has high to bacterium, dust filterability, and surgical infection rate is low, and sterilization is convenient, is easy to and other materials
The features such as compound.As disposable medical supplies it is convenient that health is not used only, moreover it is possible to effectively prevent bacterium sense in nonwoven products
Dye and medicine origin sex-intergrade infection.But presently commercially available medical textile is usually present that penetrability is poor, anti-microbial property is bad asks
Topic.
Invention content：
It is medical made from this method the object of the present invention is to provide a kind of preparation method of high-performance medical textile material
The moisture-penetrable ventilated property of textile is good, has certain anti-microbial property, and elasticity is big, and prepares simply, at low cost.
