Description
Technical field
The invention belongs to technical field of composite materials, more particularly to a kind of medical non-woven fabrics composite material and its preparation side
Method and application.
Background technology
Non-woven fabrics (non-woven cloth) is a kind of fabric that does not need to spin cotton and weave cloth and be formed, only by textile staple or
Long filament is oriented or randomizing, forms fibre net structure, then the methods of mechanical, hot sticky or chemical is used to reinforce.Letter
Single saying be exactly：It is not by one one yarns interwoven, woollen yarn knitting together, but fiber is directly passed through into the side of physics
What method was bonded together, so, when you take the viscous title in your clothes, it finds that, it is the end of a thread that can not taken out one by one.
Non-woven cloth breaches traditional weaving principle, and with technological process is short, speed of production is fast, and yield is high, at low cost, purposes
Extensively, the features such as raw material sources are more have a wide range of applications in daily production and life.But with people's health consciousness
