<p>1450831 Tufted water-laid non-woven fabric DEXTER CORP 14 March 1974 [15 March 1973] 11395/74 Heading D2B A tufted water-laid non-woven fabric has a planar body portion and a plurality of spaced fibre tufts integral therewith and extending therefrom in the form of weft-like fibre bundles, the tufts being composed of individual fibres secured to the body portion at only one end thereof. The fibres may be man made or synthetic polymeric fibres e.g. of nylon, polyester, or vinyl polymers or copolymers, rayon; optionally in combination with natural fibres such as kraft, manila, hemp or jute fibres. Inorganic fibres such as glass, quartz, ceramic, mineral wool, or asbestos fibres may also be used. The fibres may have a denier of from 1 to 15 d.p.f. and a length ranging from 1/16 inch to several inches. The fabric may be formed from a suspension of the fibres in a medium preferably having a viscosity greater than 3 centipoises. The desired viscosity may be obtained by the use of viscosity regulants such as water-soluble acrylamides, polyethylene oxide, carboxymethyl cellulose, water-soluble polymeric electrolytes of methacrylic acid and copolymers thereof, degradable enzymes, mixtures of natural and synthetic gums and inorganic salts. The fabric may be formed with a non-woven or woven scrim or gauze embedded within it, the scrim or gauze acting both as the forming element and as a reinforcing element. The fabric may be used for making wash cloths, wiping cloths, towels, wipes, sanitary napkins, blankets, dish cloths, bandages, dressings, wall coverings, insulating materials or filters inter alia.</p> |
