manufacture example 1-11）

[0046] To a copolymer composed of 50% by weight of acrylonitrile, 49% by weight of vinylidene chloride, and sodium styrene sulfonate, an acrylic fiber in which 10% by weight of antimony trioxide was added to the resin weight of the copolymer (in the table, " AF1 "indicated), the acrylic fiber ( Indicated by "AF2" in the table), nylon 66 (indicated by "NY" in the table), cotton (indicated by "Cot" in the table), flame-retardant rayon (manufactured by Setrio サケュステイオ (Sateri Oy, Finland) company Visil (registered trademark), indicated by "Vis" in the table. Lenzing FR (registered trademark) manufactured by Lenzing Co., Ltd., indicated by "LFR" in the table), para-aramid fiber (Twaron (registered trademark) manufactured by Teijin Co., Ltd. ), represented by "Twa" in the table), polyethylene terephthalate (represented by "PET" in the table) is mixed with the raw cotton composition shown in Tables 1 to 5, and spun by the usual spinning method. yarn and twisted yarn to obtain spun y...

experiment example 1）

[0048] An arc test was performed on the fabrics produced in Production Examples 1 to 4. The results are shown in Table 1. AF1 (with an average content of antimony trioxide of 10% by weight) and AF2 (with an average content of antimony trioxide of 25 wt. % by weight) in Examples 1 to 4 (Manufacturing Examples 1 to 4), the ratio ATPV was 1.3 or more. It has not been sufficiently disclosed in the prior art what kind of acrylic fiber should be used when it is desired to obtain high arc resistance with a fabric having a smaller basis weight, but this point has been clarified by the present invention.

[0050]

experiment example 2）

[0052] The arc test was implemented with respect to the fabric produced in manufacture example 1, 5, and 6. The results are shown in Table 2. In Example 1 (Manufacturing Example 1) in which the cellulose-based fiber used was natural cellulose-based fiber cotton, the ratio ATPV reached 1.3 or more, but in Comparative Example 1 (Manufacturing Example 1) using flame-retardant rayon 5) and Comparative Example 2 (Manufacture Example 6), the ratio ATPV was less than 1.3. U.S. Publication No. US2006 / 0292953 (Patent Document 2) describes that flame-retardant cotton can be used, but it shows that in order to obtain high arc resistance with a fabric with a lower basis weight, it is not necessary to flame-retardant cotton , Instead, it is necessary to use natural cellulose-based fibers that have not been flame-retardant.

Abstract

The purpose of the present invention is to inexpensively provide arc protection work clothing that is lighter than that of the conventional art; specifically, fabric and arc protection work clothing having an ATPV value of not less than 1.3 (cal / cm2 or oz / yd2). Provided is a fabric containing: 40 to 65 wt% of acrylic fibers based on the fabric weight, said acrylic fibers containing at least 8 wt% of antimony oxide relative to the resin weight of the acrylic fibers; 26 to 45 wt% of natural cellulose fibers; 5 to 15 wt% of nylon fibers; and 1 to 20 wt% of para-aramid fibers. Also provided is arc protection work clothing containing said fabric.

Description

technical field [0001] The present invention relates to a thread, a cloth, and clothes which can be suitably used for work clothes for arc protection, particularly work clothes for arc protection. Background technique [0002] Firefighters, electrical repairmen, or other workers in environments exposed to the danger of electric arcs and fires that may be generated by arcing phenomena require work clothing that is superior in arc protection. However, work clothes for arc protection known hitherto do not sufficiently satisfy this requirement. The price of work clothes that use a lot of aramid fiber becomes high. In addition, if the amount of aramid fiber used is reduced to suppress the price, the weight per unit area becomes high in order to satisfy the required properties, and as a result, it becomes considerably thick and heavy, and workability becomes difficult. [0003] Patent Document 1 describes a fiber containing 40 to 70% by weight of modacrylic fibers, 5 to 20% by w...
