1,118,232. Finishing fabrics. DEERING MILLIKEN RESEARCH CORP. 24 Nov., 1965 [24 Nov., 1964], No. 49990/65. Heading D1S. A woven fabric web 1 is continuously compacted in the weft direction by apparatus comprising upper and lower belts 4, 5 simultaneously contacting the web 1 and a tenter clip assembly 9 on each side of the web-contacting portions of the belts 4; 5, the assemblies 9 being arranged to converge whereby the belts 4, 5 are continuously advanced from an expanded to a contracted state along the web-contacting faces. As shown, a fabric 1 containing keratinous fibres passes through a bath 2 containing a reducing agent, over a roll 3 and between the belts 4, 5 made of extensible polymeric material. Pins 6 to grip the fabric 1 are mounted on the outer face of the belt 4. The belts 4, 5 are driven by rolls 7, 8 and pass around idler rolls 12, 13 and the distances between the rolls are adjusted to tension the belts 4, 5. Each assembly 9 is driven by a roll 10 and passes around an idler roll 11. The compacted fabric is wound on a roll 14 and can be set by a decating operation to oxidise the reducing agent treated keratinous fibres. Other specified fabrics contain yarns of cellulosic fibres, e.g. cotton, or thermoplastic fibres or filaments, e.g. polyester or rayon. After compacting, fabrics containing cellulosic yarns are set by cross linking agents and fabrics containing thermoplastic yarns are heat set. The yarns may be high or low twist yarns but preferably the degree of twist is insufficient to produce internal compacting forces. The compacted fabric may have either a substantially flat surface or a texture surface, e.g. a pebble effect. |
