    摘要: The thickness of a fiber-reinforced resin sheet having uniformly distributed and substantially unidirectional fibers is reduced by stretching a fiber-reinforced resin sheet starting material in intimate contact with a thermoplastic sheet having a tensile strength larger than the fiber-reinforced resin sheet. This is accomplished by heating the fiber-reinforced resin sheet at a temperature at which the resin in the fiber-reinforced resin becomes sticky and subjecting the sheets to a uniform compressive force to adhere the fiber-reinforced sheet to the thermoplastic resin sheet and then simultaneously stretching the thus-adhered sheets to form a thin fiber-reinforced sheet in which the direction of stretching is perpendicular to the direction of the fibers.

    摘要: A process for dyeing polyolefin fiber materials, which comprises contacting a polyolefin fiber material obtained by melt-spinning a mixture of crystalline polyolefin and 0.1 to 30% by weight based on the weight of the polyolefin of a copolymer of ethylene and an aminoalkyl acrylate compound represented by the formula, ##STR1## wherein R.sub.1 represents hydrogen atom or methyl group, R.sub.2 and R.sub.3 each represents hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and n represents an integer from 1 to 4, or a blend product of the said polyolefin fiber material and a polyamide fiber material, with a dye bath containing an anionic dye and at least one carboxylic acid selected from the group consisting of benzoic acid, salicylic acid, p-chlorobenzoic acid and 5-chlorosalicylic acid.
