Description

A kind of mothproof eider down composite spinning material and preparation method thereof

Technical field

The present invention relates to textile material technical field, be specifically related to a kind of mothproof eider down composite spinning material and preparation method thereof.

Background technology

In textile industry, only have Isotactic polypropylene can be used to produce textile fabric, this is because Isotactic polypropylene fiber has higher degree of crystallinity and the degree of orientation, regularity is better.Therefore Isotactic polypropylene fiber is widely used as sewing thread, bandage, textile bags and bio-medical material.But because Isotactic polypropylene fiber lacks dyeability, limit its application in textile garment field.Eider down is a kind of natural protein fibre material, except a small amount of for making warming packing material in clothes and bedding and in the composite as except reinforcing material, major part just simple processing process is used as feed or adopts the methods such as fermentation to degrade, and causes a large amount of wastes.When fiber made separately by eider down, fragility is large, tensile strength is low, is not suitable for making coat, is only suitable for being filled in inside clothes obtaining very strong warmth retention property, because eider down content in feather is very few, usually only account for 20 ~ 25%, use cost is too high, feather fiber is not utilized very well, very unfortunately.The present invention utilizes discarded feather to be degraded into keratin solution, then with the chitosan solution blend spinning of modification, compatibility is good, recycling Isotactic polypropylene fills feather fiber, reduce the consumption of feather, gain in weight, and improve the performance of the aspects such as the intensity of fiber, modulus, heat resistance, chemical resistance and anti-corrosive properties, develop novel weaving face fabric, facilitate society and expanding economy.
