Abstract
1,102,794. Fibres containing polyvinyl alcohol. KURASHIKI RAYON KABUSHIKI KAISHA. 19 Feb., 1965 [20 Feb., 1964], No. 7209/65. Heading B5B. A spinning solution having dissolved therein polyvinyl alcohol and from 0À1 to 50%, preferably from 1 to 30%, by weight based on the total polymer weight of an elastic polymer (or a pre-polymer which provides such an elastic polymer) is spun under dry, wet or semi-melt spinning conditions to from fibres containing polyvinyl alcohol. The fibres thereafter are drawn, for example in a gaseous medium such as air or in a heated liquid which is inert to the materials forming the fibres, to a draft of at least 50%, preferably of at least 500%. The polyvinyl alcohol may be a hydrolysed polyvinyl ester containing a small proportion of residual ester groups and having a degree of polymerization of from 500 to 3000. The elastic polymer or pre-polymer thereof is a polyurethane elastomer derived from a polyol, a polyisocyanate and a chain extender (but excluding basic polyurethanes derived from a polyol which is a tertiary amino compound, such as disclosed in Specification 779815), a block copolymer of polyethylene terephthalate and polytetramethylene glycol, a copolymer of ethylene terephthalate and ethylene sebacate, a N-methoxymethyl polyhexamethylene adipate, a copolymer of ethylene and vinyl acetate, a natural rubber or a synthetic rubber. Prior to spinning, the materials which will form the blended fibres may be dissolved, preferably separately, in one or more organic solvents, for example dimethylsulphoxide, dimethylformamide, dimethylacetamide, ethylene glycol, glycerine, phenol, m-cresol, nitrobenzene or dichlorobenzene; a mixture of two or more organic solvents may be used. The solvent or solvents may contain a minor proportion of water. When the fibres are formed by wet spinning, the coagulating bath may contain alcohols, for example methanol, ethanol or butanol, or aromatic hydrocarbons, for example benzene or toluene; alternatively, an aqueous coagulating bath containing an inorganic salt or salts, for example zinc chloride, may be used. The coagulating bath may also contain a solvent for the spinning solution, for example dimethylsulphoxide or dimethylformamide preferably mixed with an alcohol.
