Abstract
1304732 Conjugate filaments and fibrillar assemblies TORAY INDUSTRIES Inc 18 June 1970 29573/70 Heading B5B [Also in Division D1] The filaments of a web are multicomponent, most preferably island-in-the-sea, with at least 5 "islands", each island being of 0À001-0À5 denier. The filaments, which may be crimpted, may comprise nylon 6, 66, 610, 7, 8, 9, 11 or 12, polyethylene terephthalate, polybutylene terephthalate, polyethyleneoxy-benzoate, polyethylene, polypropylene, polyvinyl alcohol, polyacrylonitrile, polystyrene, polyurethane, or copolymers thereof. The island component may be one of the above, or polyvinyl acetate, cellulose, polyether, polycarbonate or polyalkyl substituted phenylene oxide. The "sea" component is preferably polystyrene and its copolymers, nylon 6, polymethylmethacrylate and its copolymers and polyesters. It may be dissolved out of the needled web with formic acid, sulphuric acid, benzene, xylene, toluene, dimethylformamide, dimethyl sulphoxide, acetone, water, alcohol or alkali. In Example 1, a styrene/acrylonitrile copolymer as the sea and nylon 6 as the island component were melt-spun. The extruded 16 island continuous filament was taken up at 1000 m.p.m. on a first godet roller and at 3400 m.p.m. on a second godet roller, with a heater plate at 110 C. intervening, air drawn to 2-3 denier, and air laid on to a conveyer belt. An aqueous solution of an antistatic agent was added and suction was applied to form the web and remove excess solution. The fibres had a breaking elongation of greater than 12%, preferably greater than 20% and a strength of 0À2-1À5 gm./ denier. The web fibres were cut by needling with blade carrying lances then entangled with barbed needles. Alternatively, barbed blade carrying lances may be used. The mat was impregnated with aqueous polyvinyl alcohol and dried, the "sea" component dissolved out in benzene, the sheet dried, impregnated with polyurethane in dimethylformamide, immersed in hot water to set the polyurethane, and buffed. Artificial leathers may be produced. Preferably, the island components are imperfectly crystalline, so that they shrink on heating after the web has been needled.
