FABRIC FOR PROTECTIVE CLOTHING AND SPUN YARN FOR USE THEREFOR

摘要

A protective suit fabric of the present invention is a heat-resistant flame-retardant protective suit fabric, which is formed of a spun yarn. The fiber blend rate is: 25-75 mass% of polyetherimide fiber (A); 20-50 mass% of at least one fiber (B) selected from wool and flame-retardant rayon; and 5 to 25 mass% of para-aramid fiber (C). The spun yarn for forming the fabric is a two-fold yarn (20) prepared by twisting: 1) a single yarn (24) of a uniform blended spun yarn including the fiber components (A) and (B); and 2) a single yarn (23) of a sheath-core spun yarn including a core (21) of stretch-broken spun yarn of the para-aramid fiber (C) and a sheath (22) formed by blend-spinning the polyetherimide fiber (A) and the at least one fiber (B) selected from wool and flame-retardant rayon. The protective suit fabric has high washing resistance. The protective suit fabric provides favorable comfort in wearing even if the suit is worn in the hot seasons or even if the wearer perspires during exertion. The fabric has high heat resistance and high flame retardance, favorable dye affinity, and the fabric can be produced at a low cost. Also a spun yarn used for the fabric is provided.
