Document Type and Number:
Japanese Patent JP7334394
Kind Code:
B2
Abstract:
A filament fibre production method including the process steps of: filtration of and/or applying evaporation process to wastewater containing Polyvinyl alcohol polymer from sizing process and/or painting process in a manner to contain Polyvinyl alcohol polymer at rate of 20-30% by mass, adding Carbonyl di-imidazole and Ethylenediamine or 4-chloro-Propionyl chloride and Etylendiamine into wastewater having Polyvinyl alcohol polymer in 20-30% rate as a result of filtration and/or evaporation process and obtaining PVA-Etylendiamine hydrogel solvent, adding dimethyl sulfoxide, Boric Acid, Acetic Acid and surface active agent into solvent bath containing PVA-Ethylendiamine hydrogel solvent at 20-30% rate, applying coagulation process to obtained PVA-Ethylendiamine hydrogel solvent with acetone of critic fluid phase, stretching Polyvinyl alcohol polymer passing through coagulation bath at 200 C.°-250 C.° temperature range when wet, and subjecting to fixing process.
