DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a flame retardant cloth composed of a composite fiber made from halogen-containing fiber together with polyester fiber, and having an excellent after-handling property and a high flame retardance.
PRIOR ARTS RELATING TO THIS INVENTION
Recently, it has been strongly required of the safety security for human living, and accordingly, necessity of flame retardant raw materials has been closed-up. Under these circumstances, in a field of interior goods, curtains in particular, on top of the flame retardant requirement, requirements for up-graded function such as a higher grade designing by various printing methods, a higher odorless requirement or the like have been risen.
The study for flame retarding of fibers has hitherto been carried out with respect to mixing a conventional flammable fiber with a flame retardant fiber so that flame retardance is additionally given while the superior property of conventional flammable fiber is kept as it is. Particularly, a composite flame retardant fiber product made by blending a high flame retardant fiber with a polyester fiber, which is the most conventional fiber, is very advantageous in aspects of production cost, easy designing and productivity.
However, in such a composite fiber product made by blending a flammable fiber with a high flame retardant fiber, in a pigment printing process in particular, a large amount of flammable binder is inevitably needed to use during its process. As the results, in addition to the problem of flame retardance resided in the said composite fiber product, the final flame retardance after a pigment printing processing is very difficult to be kept at the level of the said composite fiber product. Naturally, commercialized products of this kind have not been appeared in market hitherto.
On the other hand, another conventional technique, which is using a composite fiber consisting of a halogen-containing fiber having a large amount of antimony compound being added in therewith and a polyester fiber, is also not advantageous to use as the common interior materials in aspects of cost and productivity because of using a large amount of flame retardant.
Under these circumstances, the present invention can solve such problems that the extremely lowering of flame retardance in a binder process such as pigment printing process, on top of the flame retardance problem existed in such a composite flame retardant fiber product as in the above-mentioned composite flame retardant fiber consisted of a conventional polyester fiber and a halogen-containing fiber. In further, without adding such a large amount of flame retardant agent as well as with making it advantageous in its productivity, the above-mentioned fiber product can be possible to be applied for a wider field.
DISCLOSURE OF THE INVENTION
The inventors of the present invention had studied intensively to solve the above-mentioned problems. As the results, they found that in the conventional composite fiber product composed of a halogen-containing fiber containing an antimony compound and a polyester fiber, for instance, the problem that its flame retardance is lowered after a pigment printing processing of it can be solved by improving the shrinkage property at high temperature of the above-mentioned halogen-containing fiber containing a antimony compound, namely, even in a case of adding a small amount of the antimony compound, this composite fiber product composed of a halogen-containing fiber and a polyester fiber can maintain its high flame retardance. Continually, the inventors of the present invention achieved to complete this invention.
That is, the present invention is that a flame retardant cloth used as an interior material comprising (A)60-40 parts by weight of fiber which contains 8-70 wt. % of halogen chemically bonded to a polymer and 1-8 wt. % of Sb compound not chemically bonded to a polymer, and which has a shrinkage factor at 240.degree. C. of not less than 40% under a load of 300 mg/metric count yarn count(17),
