Abstract: PURPOSE:To provide the titled fiber having specific tensile strength, toughness (product of tensile strength and square root of tensile elongation) and sulfur- content, exhibiting excellent heat-resistance, flame-resistance and alkali resistance, having comparable spinnability to conventional fiber for clothes and useful for firemen's uniform, etc. CONSTITUTION:An acrylonitrile polymer composed of 99.7mol% acrylonitrile and 0.3mol% itaconic acid, etc., is dissolved in dimethyl sulfoxide to obtain a spinning dope. The dope is ejected through a spinneret into a coagulation bath composed of an aqueous solution of dimethyl sulfoxide to effect the wet- spinning. The obtained filament is drawn, sulfurized in sulfur dioxide at 280 deg.C and oxidized in air at 250 deg.C to obtain the objective flame-resistant fiber having a tensile strength of >=3.5g/d, toughness of >=10 (defined by the produce of tensile stress and square root of tensile elongation) and a sulfur content of >=5wt%.

Abstract: PURPOSE:To obtain a flame retardancy, a weatherability, and a high light transmission by a method wherein an antimony oxide, a titanium oxide, and a radical trapping agent are mixed with a vinyl chloride resin in the absence of a plasticizer, a vinyl chloride resin layer is obtained by adding and kneading a plasticizer in the mixture, a surface layer material and a base cloth are joined to the vinyl chloride resin layer. CONSTITUTION:A high-light-transmission film material 4 consists of a surface layer material 1, a vinyl chloride resin layer 3, and a base cloth 2. A vinyl chloride resin used for the vinyl chloride resin layer 3 contains an inorganic flame-retardant, a weathering agent both of which are finely divided into particles of a diameter smaller than the wavelength of a visible light for preventing an irregular reflection of a visible light on the surfaces of the particles, an antimony oxide of an average particle diameter of 0.2mum or less, and a titanium oxide of an average particle diameter of 0.2mum or less both of which are contained for transmitting a visible light in the total amount of 5 pts.wt. or more and a trapping agent for preventing the antimony oxide and the titanium oxide from producing radicals under the influence of an ultraviolet radiation in the amount of 5 pts.wt. or less per 100 pts.wt. on vinyl chloride resin. In addition, the high-light-transmission film material 4 has a transmittance of 20% or more.
