Document Type and Number:
WIPO Patent Application WO/2003/056076
Kind Code:
A1
Abstract:
A phytoprotein synthetic fibre and the method of making the same are disclosed in this invention. The synthetic fibre is consisted of vegetable protein and polyvinyl alcohol, and based on the total amount of these two materials, the amount of the vegetable protein (A, parts) is 5 parts $m(F) A $m(f) 23 parts, the amount of the polyvinyl alcohol (B, parts) is 77 parts $m(f) B $m(F) 95 parts. The method of making the same includes the procedures of semi-finished product processing and the semi-finished products being further finished and acetalized to obtain the end products. The procedure of semi-finished product processing is carried out in sequence: taking the vegetable protein and the polyvinyl alcohol according to the predetermined proportioning respectively, and then preparing the spinning dope(s); deaerating the dope followed by wet spinning in wet-spinning frame; introducing the synthetic filaments from the frame into the coagulant held in the coagulating bath, giving the semi-finished product by air drafting, wet spinning drawing, drying, dry heat stretching and heat setting. Synthetic fibes prepared by this method have the features of good breathability, etc., and the period of the manufacture is shortened, the productivity is improved.
