    摘要： This invention relates to a phytoprotein synthetic fibre and the method for the manufacture thereof. This synthetic fibre is composed of phytoprotein and polyvinyl alcohol, the phytoprotein comprising A parts of the two components, where A is equal to or greater than 5 parts and less than 23 parts, and the polyvinyl alcohol comprising B parts, where B is greater than 77 parts and equal to or less than 95 parts. The methods of manufacturing the synthetic fibre comprise a semi-finished product manufacturing process and a semi-finished product acetalization and finishing process. The sequence of processing of the semi-finished product is as follows: taking a spinning dope prepared from proportions of phytoprotein and polyvinyl alcohol, and after deaeration introducing the spinning dope to a wet-spinning frame to undergo wet-spinning; the synthetic fibre output by the spinning frame then entering a coagulant bath, the semi-finished product being obtained after air drafting, wet bath drafting, drying, dry heat drafting and heat fixing. The synthetic fibres produced as a result of the adoption of this method exhibit good breathability characteristics and require a production period of short duration, thus increasing productivity.

    摘要： A composition and process are provided for making precipitated biconstituent nylon-polyvinyl alcohol shaped articles by dissolving polyvinyl alcohol and a nylon having an amide group index of less than about 145 in a mixture of a tertiary amine oxide solvent and water, with the solution containing from about 3.0 to about 11% water, to form a biconstituent dispersion wherein the nylon and the polyvinyl alcohol comprise distinct separate phases. Shaped articles can be formed from the biconstituent dispersions of the invention.

    摘要： A water-soluble polyvinyl alcohol fiber is obtained by subjecting to the conventional dry or wet spinning process, a solution prepared by adding to a polyvinyl alcohol aqueous solution, an adduct composed of a polyamide condensation product and 1-halogen-2,3-epoxy propane or ethylene glycol diglycidyl ether in the range from 5 to 50 percent by weight based upon the polyvinyl alcohol-after the solution's pH has been adjusted to 2 to 7. The resulting fiber, which has not been subjected to any heat treatment at a temperature above 120.degree. C. is blended with a fibrous material to make a fibrous sheet such as paper or non-woven fabric. By virtue of a subsequent heat-treatment, said polyvinyl alcohol fiber becomes boiling water-resistant; as a result, the wet strength of the fibrous sheet is significantly increased.
