Problems solved by technology

[0006] However, due to the higher cost of zinc stannate compounds than antimony compounds, the cost of this fiber is higher than that of ordinary fibers. The addition of antimony compounds to halogen-containing fibers independently results in higher costs for blended fabrics.

manufacture Embodiment 1

[0052] Manufacture Example 1 (manufacture of strands of halogen-containing fireproof fiber and cotton yarn)

[0053] 52 parts of acrylonitrile, 46.8 parts of 1,1-dichloroethylene, and 1.2 parts of sodium styrene sulfonate were copolymerized to obtain an acrylic acid-based copolymer. The obtained acrylic-based copolymer was dissolved in acetone to obtain a solution having a concentration of 30%. 50 parts of antimony trioxide was added to 100 parts of the obtained copolymer to prepare a spinning solution. Through a nozzle with a hole diameter of 0.07 mm and 33,000 holes, the resulting spinning solution was extruded into an aqueous solution of acetone with a concentration of 38% at 25°C, and the filaments obtained after washing with water were dried at 120°C for 8 minutes . The obtained filaments were then drawn three times at 150° C. and subsequently subjected to heat treatment at 175° C. for 30 seconds to obtain a halogen-containing fireproof fiber with a fiber size of 3 dtex...

manufacture Embodiment 2

[0054] Manufacture Example 2 (manufacture of halogen-containing fireproof yarn and strands of cotton)

[0055] Except that 30 parts of cotton and 70 parts of halogen-containing fireproof fiber were mixed, the method similar to Manufacturing Example 1 was repeated to prepare strands, and then the spun yarn with a count of No. 17 was metric. Table 1 shows the elongation of the obtained strands.

manufacture Embodiment 3

[0056] Manufacture Example 3 (manufacture of halogen-containing fireproof fiber and strands of cotton)

[0057] Except that 40 parts of cotton and 60 parts of halogen-containing fireproof fiber were mixed, the method similar to Manufacturing Example 1 was repeated to prepare strands, and then the spun yarn whose count was No.17 was metric. Table 1 shows the elongation of the obtained strands.

Abstract

A fabric is provided that has high degree of flame resistance in the case of a union fabric consisting of a halogen-containing flame resistant fiber including antimony compounds (A), and a cellulosic fiber, and the fabric is classified into class M1 of NF P 92-503 combustion test in France. A flame resistant union fabric obtained by co-weaving: a compound yarn (A) 30% to 70% by weight obtained by compounding a halogen-containing flame resistant fiber (a-1) including an antimony compound 25 to 50 parts by weight in an acrylic based copolymer 100 parts by weight obtained by polymerizing a monomer mixture including acrylonitrile 30 to 70% by weight, a halogen containing vinyl based monomer 30 to 70% by weight, and a vinyl based monomer copolymerizable therewith 0 to 10% by weight, and an other fiber (a-2), the compound yarn (A) having an elongation percentage less than 5% under a condition of a load of 300 mg / metric count of No. 17, and of a temperature range of 100 degrees C. to 500 degrees C.; a cellulosic fiber yarn (B) 70 to 30% by weight.

Description

field of invention [0001] The present invention relates to a flame resistant union fabric. Specifically, the present invention relates to a blended fabric having a high fire resistance, which is composed of a compound yarn including a halogen-containing fireproof fiber including an antimony compound as a main component, and cellulose fibers. Background technique [0002] In recent years, the demand for safe food, clothing and housing has become stronger, and the necessity of fireproof materials has also increased. In this form, various methods have been proposed to provide flame retardant properties to combustible yarns by compounding general purpose combustible fibers with highly flame retardant fibers while retaining the properties of combustible yarns. As this composite fiber (compound fiber), for example, in Japanese Patent No.2593985 specification and Japanese Patent No.2593986 specification, all disclose a kind of in the composite of halogen-containing fireproof fiber...
