Abstract: 1,211,304. Finishing fabrics. NIPPON RAYON K.K. 29 Feb., 1968 [9 March, [1967], No. 9964/68. Headings D1P and D1S. Compressive shrinking apparatus for a woven textile fabric comprises a rotatable heated drum B, a rotatable deformable-surfaced roller A, C having its axis parallel to that of the drum, a flexible elastic belt D passing through the nip between the drum B and the roller A, C with deformation of both the roller surface C and the belt D in the nip and means for feeding the fabric in its warp direction into the nip between the drum B and the belt D. The roller A, C comprises an iron roller A having a natural or synthetic rubber surface C and the belt D may be made of rubber. Preferably, the elasticity of the belt D is greater than that of the surface C. The fabric is fed into the apparatus by tension bars 1, 2 and a guide bar 3 and is fed out by a roller 8. The fabric is temporarily fixed in its shrunk state by the drum B the surface temperature of which may be adjustable to 120-180‹C. Subsequently, the fabric may be completely heat set by heat treatment without tension in the warp direction, e.g. by a machine of the short loop type, suction drum type or conveyor type, to form an elastic fabric. Woollen fabric may be set using a decatizer wherein the fabric is wound under the lowest possible tension. Prior to the compressive shrinking, the fabric may be pre-treated at such a temperature that it is not completely heat-set. Specified treatments are desizing, scouring, dyeing, padding with a synthetic resin, e.g. polymers of dimethylol urea, glyoxal monoureide, dimethylol ethylene urea, dimethylol triazone, propylene urea, modified triazine, acetal, carbamate, carbamite, acrylamide or acrylic acid ester, and padding with a setting agent, e.g. water, alcohols, phenols, caustic soda, ammonium salts of thioglycolic acid, monoethanolamine sulphite, ethylene diamine, sodium hypophosphate, sodium hydrogen sulphite or hydrosulphite. Specified fabrics contain 65% nylon or copolymerized poly-ether-ester fibres and 35% rayon fibres or 50% copolymerized poly-etherester fibres and 50% wool fibres.

Abstract: 1,211,305. Finishing fabrics. NIPBON RAYON K.K. 29 Feb., 1968 [13 March, 1967], No. 9966/68. Heading D1S. Elasticity is imparted in the warp and weft directions to a loosely woven textile fabric composed of animal or thermoplastics yarns by scouring the fabric under a tension of from 20 to 80 Kg. per m. in its warp direction so that the fabric is shrunk in its weft direction, preferably by 20 to 40%, shrinking the fabric by 5 to 40% in its warp direction without further shrinking in the weft direction and fixing the shrunk fabric. Suitable thermoplastic yarns include filamentary yarns and staple fibre yarns having a thermoplastic nature and blended yarns composed of thermoplastic fibres or filaments and natural or regenerated fibres or filaments, e.g. blended spun yarns, paralleled yarns in which untwisted yarns are disposed parallel to each other and double-twist yarns. Examples specify 100% woollen yarns or blended spun yarns of 65 % copolymerized polyether-ester fibres or nylon fibres and 35% viscose rayon fibres or 50% copolymerized polyether-ester fibres and 50% wool fibres. As shown, a fabric F passes over a guide 1, between rollers 2, through a scouring bath 3, through water in a washer tank 4, through a roller-type drier 5 and between rollers 6 which rotate at a faster speed than the rollers 2 to apply a tension of 20-80 Kg. per m. to the fabric. The fabric may be dyed, soaped and/or sheared between the rollers 6 and a rollertype drier 7. After passing between rollers 8, the fabric is padded with a resin or setting agent in a bath 9 and dried in a roller-type drier 10 so as to retain a suitable water content. The fabric passes between rollers 11 the speed of which may be adjusted to tension the fabric between the rollers 8, 11, around tension bars 12, 13, 14 and through a shrinking apparatus comprising a rotatable heated drum 15 to heat set the fabric and around a part of the periphery of which a rubber belt 16 passes, a rubber roller or a press roller 17 having a rubber or elastic layer 18, and guide rollers 19, 20, 21, 22. The pressure exerted by the roller 17 is adjustable by a piston 23. The fabric is fed onto a guide plate 24, between rollers 25, fixed completely in a short loop-type baking machine 26 and delivered between rollers 27.

Abstract: 1,211,136. Shrinking fabrics. NIPPON RAYON CO. Ltd. 16 Jan., 1968 [30 Jan., 1967], No. 2427/68. Headings DIP and D1S. A woven textile fabric is shrunk in its weft direction by passing the fabric in its warp direction between rotatable elastic rollers 21, 22, .. 2n having axes 5 curved with the same radius of curvature and in the same plane as each other. The positions of the axes 5 are adjustable in a support 4. Pairs of guide rollers 1, 3 are provided. Each roller 21, .. 2n comprises a natural or synthetic rubber or felt body mounted on a curved metal axle. Suitable roller dimensions are specified and preferably from 2-20 pairs of curved rollers are used. The rollers may be of the same or different diameters as each other. The fabric may be fixed after shrinking, e.g. by heat setting or chemical setting or a combination of the two using a swelling agent. Prior to being passed between the curved rollers, the fabric may be treated with a resin or a swelling agent. Alternatively, the fabric may be set during the shrinking by maintaining the rollers 21 .. 2n at a suitaible elevated temperature or immersing these rollers in a bath containing a swelling agent, chemical fixing agent or resin. The fabric is woven from filaments or spun yarns of thermoplastic fibres, e.g. polyamide, polyester, polyacrylonitrile, polypropylene, polyvinyl chloride or polyurethane, regenerated cellulose fibres, e.g. viscose rayon or acetate rayon, or natural fibres, e.g. wool, silk or cotton. A specified resin treatment bath consists of an aqueous solution of dimethyl uron resin, polyethylene softener, organic silicate softener and zinc nitrate.
