Abstract
Imitation leather is made by preparing a substantially electrically neutral aqueous suspension of finely-divided particles of rubber by adding to rubber latex an aqueous emulsion of rubber particles carrying a positive electric charge, mixing the resultant suspension with a dilute aqueous suspension of mineral or preponderantly mineral fibres and forming the mixture into a sheet or rod. The preferred mineral fibres are asbestos but any other fibres may also be added which can be used as a filter mass when suitably treated, e.g. by dry teasing or grinding or wet beating or pulping, such as cellulose fibres. The latex may be given a positive charge by means of cationic soaps as described in Specifications 497,793 and 538,505, [Group III], and then the treated latex further modified by the use of silicate or phosphate ions or by aniline dyes. Vulcanizing agents may be added and the mix after flocculation poured on to a gauze, e.g. of 40-60 mesh per sq. inch and the excess moisture removed under vacuum to form sheets or rods.
