And heat-treating the polyvinyl alcohol nanoweb generated in the electrospinning step from a temperature above a glass transition temperature to a temperature below a crystallization temperature. 본 발명에 의한 폴리비닐알코올 나노 섬유 부직포의 제조방법은 열처리를 통한 결정성의 향상과 부분가교를 통한 내수성의 향상으로 용도의 전개를 쉽게 할 수 있으며, 용매로 증류수만을 이용하고, 어떤 화학적 처리를 하지 않음으로서 폴리비닐알코올이 가지는 생체적합성의 고유한 성질을 변화시키지 않으면서도 전기방사시 제조되는 나노웹의 특성을 발현시킴으로써 의료용 응용분야로의 폭넓은 확대를 가질 수 있는 장점이 있다. The method for producing a polyvinyl alcohol nanofiber nonwoven fabric according to the present invention can be easily developed by improving the crystallinity through heat treatment and the water resistance through partial crosslinking, using only distilled water as a solvent, and not performing any chemical treatment. By not expressing the properties of the nanoweb prepared during electrospinning without changing the inherent properties of the biocompatibility of polyvinyl alcohol has the advantage that it can have a broad expansion into medical applications. 전기방사, 폴리비닐알코올, PVA, 생체친화성고분자 Electrospinning, polyvinyl alcohol, PVA, biocompatible polymer

Novel polyvinyl alcohol products

Номер: RU2518657C2

FIELD: chemistry. SUBSTANCE: claimed invention relates to polyvinyl alcohol nonwoven films and fabrics and method of obtaining them. Nonwoven air-permeable fabric or film contains polyvinyl alcohol and has at least one coalesced surface layer, containing low porous polyvinyl alcohol, and layer, consisting in fact from fibrous polyvinyl alcohol. Said coalesced layer is more susceptible to heat transmission that said fibrous layer. Method of selective modification of surface of polyvinyl alcohol film or fabric is realised by selective coalescing of at least one surface of polyvinyl alcohol by means of heat and water with formation of low porous surface layer, attached to layer of non-modified polyvinyl alcohol. Film or fabric are soluble at higher temperatures. EFFECT: provided is obtaining outer surface of polyvinyl alcohol air-permeable fabric with unlimitedly regulated porosity and susceptibility to heat transmission, instant dissolution in water with temperature 80-90°C. 19 cl, 8 dwg, 3 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 518 657 C2 (51) МПК B32B 27/00 (2006.01) B32B 5/02 (2006.01) D04H 1/40 (2012.01) C08F 16/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2012130454/12, 17.07.2012 (24) Дата начала отсчета срока действия патента: 17.07.2012 (72) Автор(ы): СМИТ В.

A method for manufacturing a regenerated protein fiber is provided to supplement the material property of the protein fiber, by adding polyvinyl alcohol and alginic acid into collagen protein so as to form a spinning solution for the protein fiber. A spinning solution is formed by mixing collagen protein, polyvinyl alcohol, and a cross-linking material, wherein the collagen protein is obtained by using saving scrap as a raw material. The spinning solution is wet-spun within a coagulation bath containing two or more kinds of coagulation material. The resultant material is chemically cross-lined within a cross-linking bath containing a cross-linking material. The spinning solution is formed by mixing the collagen protein, the polyvinyl alcohol, the cross-linking material, and alginic acid of 0.1~10 wt%.
