摘要
The multilayer-structured spun yarn of the present invention is a multilayer-structured spun yarn C composed of a core fiber A and a cover fiber B that wraps around the core fiber; the core fiberAis in a range of 20 to 50 wt%; the cover fiber B is in a range of 50 to 80 wt%; the core fiber A contains a para-aramid fiber and is a stretch breaking twist yarn; the cover fiber B contains a flame-retardant acrylic fiber, a polyetherimide fiber, or a meta-aramid fiber; the direction of twist of the stretch breaking yarn and the direction of twist of the multilayer-structured yarn are the same; and the multilayer-structured yarn C has a twist number 1.2 to 1.6 times greater than that of the stretch breaking yarn. The heat-resistant textile of the present invention uses the aforementioned multilayer-structured spun yarn. The heat-resistant protective suit of the present invention uses the aforementioned heat-resistant textile.
