| titleOfInvention | Improvements in the treatment of woollen fabrics |
| abstract | 949, 883. Treating woollen fabrics. J.P. STEVENS & CO. Inc. Dec. 7, 1961 [Dec.12, 1960], No. 43859/61. Headings D1K, D1L and D1P A woven fabric comprising a set of weft yarns and a set of warp yarns of which one of the sets comprises wool and is preferably of woollen yarns which have been highly twisted, is treated at an elevated temperature with a solution of a stabilizing agent capable of setting the yarns to cause shrinkage of the yarns, treated to permanently set the yarns in their contracted state and is then dried by the application of heat while it is in a loose, tensionless state, to produce a fabric in which the wool is in a highly crimped and bulked state and which is capable of stretching by at least 8% and of returning to its contracted state when the stretch force is released. The stabilizing agent may be monoethanolamine sulphite, thioglycolic acid or its calcium or sodium salts, sodium formaldehyde sulphoxylate, sodium bisulphite or sodium borate and the treating solution may also contain a sequestering agent, e.g. a non-toxic alkylarylpolyether. The fabric may be treated with the solution of the stabilizing agent at 212-230 F. under a pressure adapted to prevent the liquid from boiling and may be cooled by the passage of cold water therethrough to a temperature to arrest the action of the stabilizing agent prior to drying. The fabric which may comprise textured yarns, e.g. crepes, boucles, slub and flake yarns, may subsequently be treated with an aqueous solution of hexamethylene diamine and a solution of sebacyl chloride in trichlorethylene or perchlorethylene to deposit a coating of nylon on the fibres. As shown in Fig. 1 the fabric 9 in a wet or dry state may be rolled loosely on drum 11 having perforations 12, covered with a fabric sleeve 13 and placed in treating vessel 20 containing the solution of the stabilizing agent admitted from reservoir 41 and recirculated by pump 30 driven by motor 31, and heated in heat exchanger 35 provided with steam pipes 36 for supplying steam at elevated pressures. After treatment with the stabilizing agent the package is removed from the vessel 20, unrolled on a pair of supporting rollers 51 shown in Fig. 2, passed between a pair of squeeze rolls 52 to reduce its liquid content to a predetermined value to scray 54 and slack loop dryer 55 supplied with hot air from pipe 56 where it is free to shrink. Alternatively after treatment with the solution of the stabilizing agent the fabric may be squeezed and wound with a fabric apron on a decatising machine as shown in Fig. 3 comprising a drum 60 having perforations 61 on which the wet treated fabric 62 is rolled from a supply roll 63 with an interleaved fabric apron 64 delivered from supply roll 65 and heated by steam supplied to the interior of the drum and then through the perforations 61 for 3-5 minutes. The fabric may then be cooled by passing cold water therethrough, removed from the decatising machine and dried in a slack loop drier. |
