DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a flame-retardant fabric comprising a halogen-containing fiber, a polyvinyl alcohol fiber and a polyester fiber, and having an excellent heat resistance, an excellent processability and a high flame retardance.
BACKGROUND OF THE INVENTION
In recent years, it has been increasingly required to secure safety of food, clothing and shelter, and the necessity of flame-retardant materials has been in demand. Under such circumstances, the improvement of the designing by various prints in addition to the above-mentioned flame retardance and the improvement of deodorization have been in demand in the field of interior materials, especially curtains.
A method in which a flame retardance is imparted to general-purpose inflammable fibers by blending the same with highly flame-retardant fibers has been so far conducted. Especially, it is quite advantageous in view of a cost, a designing and a productivity that polyester fibers, the most general-purpose fibers are blended with highly flame-retardant fibers to form flame-retardant composite fibers. In recent years, composite fibers of polyester fibers and halogen-containing fibers, especially, modacrylic fibers are chiefly being used in flame-retardant curtain materials.
However, since acrylic fibers having a how heat resistance are used in this composite fiber product, the acrylic fibers are hardened in processing requiring a high temperature, such as transfer printing, providing a poor feeling. For this reason, the very product is actually not produced commercially.
SUMMARY OF THE INVENTION
The present invention has been made to solve the above-mentioned problems and to further widen the range of application of the polyester fiber product.
The present inventors have assiduously conducted investigations to solve the above-mentioned problems, and have consequently found that when a conventional fabric comprising a halogen-containing fiber containing an Sb compound and a polyester fiber is subjected to transfer-printing, a feeling is notably decreased, whereas when the composite fiber comprising the halogen-containing fiber containing the Sb compound and the polyester fiber is further blended with an inflammable polyvinyl alcohol fiber, a heat resistance can surprisingly be improved without impairing the flame retardance although the inflammable fiber is added. This finding has led to the completion of the present invention.
That is, the present invention relates to a flame-retardant fabric comprising (A) from 16 to 45 parts by weight of a halogen-containing fiber containing from 11 to 67% by weight of a halogen chemically bound to a polymer and from 4 to 30% by weight of an Sb compound not chemically bound to a polymer, (B) from 10 to 36 parts by weight of a polyvinyl alcohol fiber, and (C) from 60 to 40 parts by weight of a polyester fiber, which are compounded to total 100 parts by weight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The fiber (A) constituting the flame-retardant fabric in the present invention contains from 11 to 67% by weight, preferably from 17 to 45% by weight of a halogen chemically bound to a polymer. Examples of the fiber (A) containing from 11 to 67% by weight of the halogen include a fiber formed of a polymer of a halogen-containing monomer, a fiber formed of a copolymer composed of the halogen-containing monomer and a halogen-free monomer, a polymer blend of a halogen-containing polymer and a halogen-free polymer, and a fiber formed of a halogen-containing polymer in which a halogen is introduced in the post treatment. However, these are not critical.
Specific examples of the halogen-containing polymer include a homopolymer of a halogen-containing monomer such as vinyl chloride, vinylidene chloride, vinyl bromide or vinylidene bromide, or a copolymer of two or more of these monomers; a homopolymer of a halogen-containing vinyl monomer or a halogen-containing vin
