Abstract: 1318211 Forming yarns ALLIED CHEMICAL CORP 2 Sept 1970 [2 Sept 1969 28 May 1970 (2)] 42054/70 Headings D1F and D1W Multifilament yarn, which may be woven or knitted into wrinkle-resistant fabrics, comprises individual filaments bonded one to another, but not necessarily in direct contact, at points at average distances along the filaments of from 20 to 2000 times the average diameter of a bonded filament by blobs of adhesive which have an average diameter of from one quarter to ten times the filament average diameter. The filaments may be of a polyamide, e.g. polycaproamide, polyolefin, e.g. polypropylene, polyester, polyester/cotton blend, polyacrylonitrile, polyvinyl alcohol, viscose rayon or cellulose acetate. The adhesive may be an elastomer and/or may be of a similar or different polymer as the filaments and contain substituents which are more soluble in at least one liquid than the filament polymer. The blobs may contain particles of material, e.g. starch, cellulose, chalk, clay or alumina, short hairs or fibres, glass or foamed or unfoamed synthetic resin, insoluble in the adhesive and dispersed or occluded therein. In a method of manufacture, the filaments of an initial yarn which have been spread, as by application of an electrical charge, are bonded by spraying them with adhesive, with or without a liquid as a solvent or dispersion medium or carrier, to deposit droplets thereof on the filaments and if a liquid has been employed it is subsequently evaporated or volatilised. Alternatively the filaments are sprayed with droplets of a substance which reacts with the filament material to form the adhesive blobs. The yarn is maintained in separated form until the adhesive is set, perhaps by heating and subsequent cooling.

Abstract: 1,152,087. Forming, stapling and treating rovings and laps of glass fibre. OWENSCORNING FIBERGLAS CORP. 21 Sept., 1966 [6 Oct., 1965], No. 42100/66. Headings D1F, D1J and D1N. In the manufacture of glass fibre products, the bare filaments of a glass roving are maintained as a group, during processing or between processing stages, by moistening the filaments or roving, before or after gathering or formation thereof, with water or "equivalent inert vapourisable liquid" which upon (eventual) removal by volatilisation - as may be effected by passage of the roving or cut lengths thereof through a dielectric or radiant heating oven - does not leave a residue and does not leave the filament adhered to one another. The conventional use of size or bonding material is thereby eliminated. The moistening and succesive treatment stages may be effected continuously and the moistened roving may be wound into packages and/or perhaps rewound as a multiple roving, each package being enclosed in a moisture impervious envelope and stored against future use, or a roving package may be moistened by immersion before further processing or storage. In the apparatus shown in Fig. 2, filaments are attenuated and then gathered into a wound package 35 on a sleeve carried by a collet 40 driven by a motor 42 the speed of which is progressively reduced in accordance with the increasing diameter of the package so as to maintain a constant linear speed of the filaments. Traverse mechanism, for a member disposed adjacent the periphery of the package for guiding the roving thereonto, includes a hollow swingable arm 46 with a tubular section 48 housing a traverse actuating cam 50 which is driven by motor 42 through chain 56 and sprockets 57, 58, to ensure a set speed ratio between the collet and the traverse. As shown in Fig. 4, wet rovings 22 drawn from saturated packages 35 are cut by the knives 65 of enclosed roller devices 64 into short lengths which fall onto an endless conveyor 74 passing through an oven 80. The dried, cut filaments may be used as a reinforcement for plastics products.
