Description
Technical field
The present invention relates to a kind of carboxymethyl chitosan fiber non-woven fabric and its production technology and applications, belong to non-woven cloth skill
Art field.
Background technology
It is well known that the fiber due to good water absorption easily becomes paste in water, fiber can not be formed, therefore, is being prepared
Spun lacing method can not be used to prepare in the process, therefore, carboxymethyl chitosan fiber non-woven fabric traditional handicraft is to use needle point method system
It is standby.Needle point method production non-woven fabrics is entirely by a kind of mechanism, i.e. the pricker puncture effect of needing machine, by fluffy fibre web
It reinforces obvolvent and obtains strength.Fibre web is worn repeatedly using pricker of triangle section (or the other sections) seamed edge with barb
Thorn.When barb passes through fibre web, web surface and local inner layer fiber are forced and be pierced into inside fibre web.Due to the friction between fiber
Effect, originally fluffy fibre web is compressed.When pricker exits fibre web, the fibre bundle barb of piercing and stay in fibre web, this
Sample, many fibre bundles, which tangle fibre web, prevents it from restoring original soft fluffy state again.It is considerable by needle thorn many times
Fibre bundle is pierced fibre web, keeps fiber in fibre web entangled to each other, has the needle point method of certain strength and thickness is non-to knit to be formed
Producing material material.
The defect that needle point method prepares non-woven fabrics is inevitable in the presence of the mechanical damage to fiber, causes the performance of fiber
