Abstract

PROBLEM TO BE SOLVED: To prevent a sprinkly colored state from occurring at the time of dyeing and printing a flame retardant woven fabric containing cellulosic fibers specified in warp yarns and flame retardant fibers specified in weft yarns without deteriorating performances such as flame retardance. SOLUTION: This flame retardant woven fabric is combining and weaving yarns prepared by mix spinning of 60-90 pts.wt. halogen-containing fibers containing an Sb compound in an amount of 6-50 wt.% based on a polymer containing 17-70 wt.% halogen in the polymer with 10-40 pts.wt. cellulosic fibers so as to provide 100 pts.wt. sum total thereof as weft yarns with warp yarns of 100 wt.% cellulosic fibers in a satin weave. Since the cellulosic fibers compounded with halogen-containing fibers prepared by highly intensifying the flame retardance with a flame retardant have hitherto been used as the weft yarns containing only the flame retardance used therein and formed into a union cloth with warp yarns composed of the cellulosic fibers, the woven fabric having the flame retardance without providing a sprinkly colored state at the time of dyeing or printing is obtained.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The halogen-containing fiber used in the present invention is a highly flame-retardant fiber containing a flame retardant, and is composed of a polymer containing 17 to 70% by weight of halogen. Fibers containing 6 to 50% by weight of the Sb compound are preferably used.

Examples of the polymer containing 17 to 70% by weight of the halogen include a polymer of a halogen-containing monomer, a polymer to which a halogen-containing compound is added, and a halogen-impregnated polymer by post-processing.

Specific examples of the halogen-containing polymer include homopolymers of halogen-containing vinyl monomers such as vinyl chloride, vinylidene chloride, vinyl bromide and vinylidene bromide, and halogen-containing vinylidene monomers. Acrylonitrile-vinylidene chloride, acrylonitrile-vinyl chloride, acrylonitrile-vinyl chloride-vinylidene chloride, acrylonitrile-
Halogen-containing vinyl monomers such as vinyl bromide, acrylonitrile-vinylidene chloride-vinyl bromide, acrylonitrile-vinyl chloride-vinyl bromide, or copolymers of halogen-containing vinylidene monomers and acrylonitrile; vinyl chloride, vinylidene chloride, odor Acrylonitrile and a copolymer of a vinyl monomer or a vinylidene monomer copolymerizable with one or more of a halogen-containing vinyl monomer such as vinyl chloride and vinylidene bromide, or a vinyl monomer or vinylidene monomer copolymerizable therewith; acrylonitrile A polymer obtained by adding a halogen-containing compound to a homopolymer; a halogen-containing polyester; and the like, but is not limited thereto. Further, the above homopolymers and copolymers may be appropriately mixed and used.

The vinyl monomer or vinylidene monomer copolymerizable with the acrylonitrile, the halogen-containing vinyl monomer or the halogen-containing vinylidene monomer includes, for example, acrylic acid or its ester, methacrylic acid or its ester, acrylamide , Methacrylamide, vinyl acetate, vinyl sulfonic acid or a salt thereof,

Mixtures of more than one species can be used.

In the present invention, as the halogen-containing polymer, 30 to 70% by weight of acrylonitrile, 70 to 30% by weight of at least one of a halogen-containing vinyl monomer and a halogen-containing vinylidene monomer, and copolymerizable with these. A copolymer comprising at least one kind of a vinyl monomer or a vinylidene monomer in an amount of 0 to 10% by weight is suitably used. If the acrylonitrile content is less than the above range, the heat resistance of the polymer is remarkably reduced, which is unsuitable as a fiber product. If the acrylonitrile content is more than the above range, the halogen content is reduced and the flame retardant performance is reduced. Further, when the halogen-containing monomer is less than the above range, the flame-retardant performance decreases, and when it exceeds the above range, the heat resistance decreases and it is unsuitable as a fiber product.

As mentioned above, the halogen content in the polymer of the halogen-containing fiber is 17 to 70% by weight, preferably 22 to 70% by weight.
~ 45% by weight. If the halogen content is less than 17% by weight, it is difficult to make the manufactured woven fabric flame-retardant, and if it exceeds 70% by weight, the physical properties (strength, elongation, heat resistance, etc.), dyeability, Performance such as feeling becomes insufficient, and both are not preferable.

The Sb compound used in the present invention is an inorganic antimony compound such as antimony trioxide, antimony pentoxide, antimonic acid, antimony oxychloride, etc., and may be used alone or in combination. This Sb
The content of the compound is 6 to the halogen-containing polymer.

If the Sb compound exceeds the above range, the physical properties (strength and elongation) of the woven fabric or nozzle clogging during the production of halogen-containing fibers will be difficult. , Filter cloth clogging, etc.
Problems occur in the manufacturing process, and both are not preferred.

Specific examples of the cellulosic fiber include:
Examples include, but are not limited to, vegetable fibers such as cotton and hemp, and regenerated fibers such as viscose rayon fiber and cupra fiber. These fibers may be singly combined with the halogen-containing Sb-containing fiber, or two or more kinds thereof may be combined with the halogen-containing Sb-containing fiber.

The weft constituting the flame-retardant woven fabric of the present invention is a composite of the above-mentioned halogen-containing fiber and cellulosic fiber, and the mixing ratio thereof is as follows. ９０90 parts by weight, and 10-40 parts by weight of the cellulosic fiber are combined so that the total thereof becomes 100 parts by weight. When the content of the halogen-containing fiber is less than the above range, it is difficult to make the manufactured woven fabric flame-retardant, and when the content of the halogen-containing fiber exceeds the above range, marbling occurs during dyeing or printing. When the cellulosic fiber is less than the above range, marbling occurs at the time of dyeing or printing, and when the cellulosic fiber exceeds the above range, it is difficult to make the manufactured woven fabric flame-retardant.

The flame-retardant woven fabric according to the present invention comprises a blended yarn obtained by blending the above-mentioned halogen-containing Sb-containing fiber and cellulosic fiber as a weft, which is made of 100% cellulosic fiber.
It can be manufactured by cross-weaving a warp yarn and a satin weave.
