Abstract

644,648. Agglutinated fibrous materials. BRITISH RUBBER PRODUCERS' RESEARCH ASSOCIATION, and BLOW, C. M. March 15, 1948, No. 7748. [Class 140] Carded fibrous materials of animal fibre such as wool, or vegetable fibres such as cotton or jute, or waste natural or artificial material such as rayon, are improved as regards tensile strength, permanent resilience, and stable disposition of the fibres against migration by treating the carded fibre in thin web or sliver form, preferably as it leaves the carding engine, with a spray or mist of dilute stabilized rubber latex or the like, in such a manner as to deposit discrete droplets on the web, the amount of liquid or the number of droplets being insufficient to produce a continuous film of liquid over the surface of the fibrous material, and evaporating the moisture content from the droplets leaving minute rubber particles effecting bonds between adjoining fibres at their points of intersection, but not forming a continuous film of rubber over the surface of the material. The latex may be natural rubber latex, or an aqueous dispersion of natural or synthetic rubber-like material, vulcanized or vulcanizable, and including stabilizers permitting it to be used in dilute form, with preferably less than 10 per cent solids content. A cationic stabilizer such as an alkyl ammonium halide, which renders the charge on the rubber particles positive, or an anionic stabilizer such as an alkyl sodium sulphate or sulphonate or a non-ionic type such as a fatty alcohol ethylene oxide condensate may be used. Drying may be effected by passing the treated web over steam or hot water pipes or electrically heated elements, or by infra-red radiation from above. The latex may be pigmented to increase heat absorption. Successive webs may be superposed to form a multiple layer, either before or after drying. Specification 497,793, [Group V], is referred to.
