Abstract

The invention addresses the problem of providing a cloth and a protective product that have lightweight properties, wearing comfort, and further protection performance against electric arcs. A means for resolution is a cloth including a spun yarn containing a meta-type wholly aromatic polyamide fiber, wherein the cloth has a lightness index L-value of 25 or less.

First claim

The invention claimed is:

1. A cloth, comprising a spun yarn containing (i) a meta-type wholly aromatic polyamide fiber containing carbon black in an amount of 1 to 9% by weight with respect to the weight of the fiber, (ii) a cellulosic fiber, and (iii) a para-type wholly aromatic polyamide fiber, and having a lightness index L-value of 25 or less, and having a thickness of 0.32 to 0.45 mm, and having an ATPV value of 8 cal/cm 2 or more in Arc Resistance Test ASTM F1959-1999.

2. The cloth according to claim 1 , wherein the spun yarn contains the meta-type wholly aromatic polyamide fiber in an amount of 25% by weight or more with respect to the weight of the spun yarn.

3. The cloth according to claim 1 , wherein the spun yarn further contains a molten fiber in an amount of 5 to 20% by weight with respect to the weight of the spun yarn.

4. The cloth according to claim 3 , wherein the molten fiber is at least one member selected from the group consisting of vinylon fibers, nylon fibers, and polyester fibers.

5. The cloth according to claim 3 , wherein the single-fiber cross-sectional shape of the molten fiber is a round shape, modified shape, or hollow shape.

6. The cloth according to claim 1 , wherein the cloth has a woven fabric structure.

7. The cloth according to claim 1 , wherein the cloth has a basis weight within a range of 3.0 to 9.0 oz/yd 2 .

8. The cloth according to claim 1 , which has a limiting oxygen index LOI of 26 or more.

9. A protective product comprising the cloth according to claim 1 and selected from the group consisting of protective garments, fireproof garments, work garments, activity garments, gloves, and members for protection.
