Problems solved by technology

In addition, JP-A-8-218259 describes that by mixing a small amount of heat-resistant fiber and a fiber containing halogen and Sb that can be used for work clothes with cotton, etc., excellent hand feeling and hygroscopicity are obtained. Highly flame-retardant and highly flame-retardant fiber composites, but when used as non-woven fabrics to prevent the polyurethane used in furniture and bedding from igniting, there are difficulties in processing in the manufacture of non-woven fabrics, and bulkiness during honing processing Insufficient performance, lack of luster and color design due to a certain amount of fibers added with a large amount of flame retardants, although it is self-extinguishing when it leaves the fire source, it will be exposed to intense In flames, as a flame-retardant fiber composite, there are still problems such as insufficient flame-retardant and fire-resistant properties of cotton and polyurethane foam used in the above-mentioned bedding and furniture.

manufacture example 1

[0092] A copolymer composed of 51% by weight of acrylonitrile, 48% by weight of vinylidene chloride, and 1% by weight of sodium p-styrenesulfonate was dissolved in dimethylformamide so that the resin concentration was 30% by weight. 15 parts of antimony trioxide was added to 100 parts of resin weight of the obtained resin solution to form a spinning dope.

[0093] The above-mentioned antimony trioxide has a uniformly adjusted particle diameter of 2 μm or less, which is adjusted in advance to be uniformly dispersed in a diluted resin solution before use.

[0094] Using a nozzle with a nozzle diameter of 0.08mm and a nozzle with a number of 300 holes, extrude the spinning stock solution containing antimony trioxide into a 50% by weight aqueous solution of dimethylformamide, wash it with water, dry it at 120°C, and then elongate it. 3 times, and then heat-treated at 145° C. for 5 minutes to obtain a fiber (A).

Abstract

A flame-retardant fiber composite which comprises: 20 to 85 wt.% fibers (A) comprising 100 parts by weight of a polymer containing at least 17 wt.% halogen atoms and 0.5 to 50 parts by weight of an antimony compound; 5 to 80 wt.% heat-resistant fibers (B); 0 to 40 wt.% cellulosic fibers (C); and 0 to 40 wt.% flammable fibers (D). When used in applications such as indoor furniture or beddings, the composite further improves the flame retardancy of materials and enables the materials to be used in fields where higher flame retardancy is required.

Description

technical field [0001] The present invention relates to the problem that the previous flame retardant fiber composites were difficult to solve, that is, the flame retardancy of the bedding is further improved, and the processability and bulkiness are improved. In addition, the processability, hand feeling and touch feeling are good. Inexpensive and highly flame retardant fiber composites and fabrics made from them for designer furniture and bedding. Background technique [0002] In order to prevent fires, it is desirable to impart flame retardancy to materials used for living room furniture, bedding, and the like. In order to make furniture and bedding comfortable to use, flammable materials such as cotton or polyurethane foam are usually used, so in order to prevent fire, it is important to prevent this flammable material from being exposed to flames for a long time. In addition, the fireproof material must not impair the comfort and design of furniture and bedding. Vario...
