Abstract: 1,087,462. Laminates. DUNLOP SEMTEX Ltd. March 16, 1964 [April 3, 1963; June 28, 1963], Nos. 13101/63 and 25717/63. Heading B5N. In a method of making a laminate suitable for flooring, sections of thermoplastic sheeting are united to a backing sheet with gaps between the sections, a fluid composition or a powder is applied over the sections and excess removed, and the fluid composition or powder is converted into a coherent solid thermoplastic composition by heating and, if necessary, pressure, so as to fill the gaps between the sections with a thickness of thermoplastic material substantially equal to the thickness of the sections. Suitable fluid compositons include vinyl chloride resin paste or plastisol, and if a powder is used it may be a vinyl chloride resin in powder form associated with a plasticizer (e.g. a mixture of dialkyl phthalates in which the alkyl groups have 7 to 9 carbon atoms) and a stabilizer. The thermoplastic sheeting may also be a vinyl chloride resin composition, and the sections may be any shape, or colour including marbled effects. The fluid composition or powder may be differently coloured from the thermoplastic sections or may be transparent or translucent to show the colour of the backing sheet. The backing sheet may also be of vinyl chloride resin composition or other thermoplastic sheeting, or may be of asbestos felt or paper felt in which case an adhesive, such as a dispersion or solution of acrylic polymer or a butadiene-acrylonitrile co-polymer or butadiene-styrene co-polymer or a blend of such copolymers with P.V.C. or polyvinyl acetate, is used to bind the thermoplastic sections to the backing sheet. The vinyl chloride resin used may be a copolymer of vinyl chloride with vinylidene chloride or vinyl acetate. Reference has been directed by the Comptroller to Specification 938,411.

Patent GB-1260957-A (GB)
Title: Fibrillated yarns and films consisting of mixtures of linear thermoplastic polymers
Inventor: LAMB GEORGE EDWIN ROBERT
IPC: D01D5/42
Filed: 1969-03-13
Abstract: 1,260,957. Fibrillated yarns. ALLIED CHEMICAL CORP. 13 March, 1969 [13 March, 1968], No. 13410/69. Heading B5B. [Also in Divisions C3 and D1] A fibrillated shaped extrudate is produced by extruding an intimate mixture consisting of 10 to 80% by weight of each of (a) a fibre-forming polyamide, (b) fibre-forming polyester and (c) a fibre-forming polyolefin, orienting the extrudate by stretching it at a temperature between the extrusion temperature and ambient temperature and then fibrillating the oriented extrudate so as to convert it into a relatively high bulk fibrillar structure, the degree of stretching being sufficient to permit fibrillation of the extrudate without disintegrating it. The extrudate is suitably in the form of a "strand", which term is defined as including narrow strips of film tapes and mono-filaments. In the examples, the strand is a monofilament of 0À3 to 0À5 mm. diameter prior to being stretched. The polyamide, which desirably constitutes 20-70% of the mixture may be polycaprolactam or polyhexamethylene adipamide. The polyester may be polyethylene terephthalate and the polyolefin may be polypropylene. The stretching of the extrudate may be effected in more than one step. Thus a strand, after having been stretched in one or more stages, e.g. using a pin, may be fibrillated by mechanical means, e.g. slightly crushed by passing it between two rollers, the clearance between which is somewhat less than the diameter of the drawn monofilament and may then be passed through a device in which the partially fibrillated monofilament is subjected to turbulent vibratory or flagellating action by a high pressure air jet whereby further fibrillation is effected and the bulk of the material increased. The process of the invention may be used for the production of fine apparel yarns without the necessity of extruding continuous filaments and forming staple fibres as an intermediate step.
