manufacturing example 1

[0082] A copolymer comprising 51% by weight of acrylonitrile, 48% by weight of vinylidene chloride, and 1% by weight of p-sodium styrene sulfonate was dissolved so that a resin concentration might give 30% by weight into dimethylformamide. Antimony trioxide 15 parts was added to 100 parts of a resin weight of the obtained resin solution to obtain a spinning solution.

[0083] The antimony trioxide had a particle diameter uniformly adjusted to not more than 2 micrometers, and was beforehand adjusted so that it might disperse uniformly in a diluting resin solution.

[0084] A spinning solution including antimony trioxide was extruded into an dimethylformamide aqueous solution with a concentration of 50% by weight, using a nozzle having a diameter of nozzle hole of 0.08 mm, and a number of holes of 300 holes. The obtained fiber was dried at 120 degrees C. after washing with water, subsequently, after drawing at 3 times, heat treatment was given at 145 degrees C. for 5 minutes to obtain a f...

[0086] A copolymer comprising 56% by weight of acrylonitrile, 41% by weight of vinylidene chloride, and 3% by weight of sodium 2-acrylamide-2-methylpropanesulfonate was dissolved into dimethylformamide so that a resin concentration might give 20% by weight. Antimony trioxide was added into the obtained resin solution to give a spinning solution. Table 1 shows amounts of addition of antimony trioxide.

Abstract

The present invention relates to a flame resistant fiber composite obtained by compounding: 20 to 85% by weight of a fiber (A) containing 0.5 to 50 parts by weight of an Sb compound to 100 parts by weight of a polymer containing halogen atom of not less than 17% by weight; 5 to 80% by weight of a heat-resistant fiber (B); 0 to 40% by weight of a cellulosic fiber (C); and 0 to 40% by weight of an inflammable fiber (D). Use of the composite in furniture, beddings, etc. in house increasingly improves flame resistance of materials, enabling use in fields requiring advanced flame resistance.

Description

TECHNICAL FIELD [0001] The present invention relates to an inexpensive and advanced flame resistant fiber composite for furniture and beddings that can solve difficult problems for conventional flame resistant fiber composites, that is, improved flame resistance of bedding products; further improved processability and bulkiness; and satisfactory processability, touch, feeling, and sensuousness, and to a fabric produced using the flame resistant fiber composite. BACKGROUND ART [0002] Flame resistance is preferably given to materials used for furniture, beddings, etc. in a house for prevention of fire. Since flammable materials, such as cotton and urethane foams, are used for comfort in use of furniture or beddings, prevention of flaming to the flammable materials over a long period of time is important for fire prevention. In addition, the flame retardant materials to be used must not impair comfort or sensuousness of the furniture or beddings in use. Although various flame resistant...
