Abstract
(EN)
This multilayered spun yarn (20) comprises a core component (21) constituted of para-based aramid fiber yarns obtained by stretch breaking spinning and a sheath component (22) including polybenzimidazole fibers, wherein the sheath component (22) has been obtained by mix spinning so as to include the polybenzimidazole fibers and meta-based aramid fibers, the polybenzimidazole fibers and the meta-based aramid fibers having at least two different colors. In the multilayered spun yarn (20), the polybenzimidazole fibers and the meta-based aramid fibers apparently differ in color tone. This heat-resistant fabric is obtained using the multilayered spun yarn, and this heat-resistant protective garment is obtained using the heat-resistant fabric. Thus, a multilayered spun yarn which renders color matching easy and has not only high laundering resistance but also high heat resistance and flame retardancy, a heat-resistant fabric obtained using the multilayered spun yarn, and a heat-resistant protective garment are provided.
(FR)
L'invention concerne un filé multicouche (20) qui comprend une âme centrale (21) constituée de fils de fibre para-aramide obtenus par filage par allongement à la rupture, et un élément gaine (22) comprenant des fibres de polybenzimidazole, l'élément gaine (22) ayant été obtenu par filage par mélange de façon à inclure les fibres de polybenzimidazole et les fibres méta-aramides, les fibres de polybenzimidazole et les fibres méta-aramides comprenant au moins deux couleurs différentes. Dans le filé multicouche (20), les fibres de polybenzimidazole et les fibres méta-aramides diffèrent visiblement en termes de nuance de couleur. Ledit tissu résistant à la chaleur est obtenu à l'aide du filé multicouche, et ledit vêtement de protection résistant à la chaleur est obtenu à l'aide du tissu résistant à la chaleur. Ainsi, l'invention concerne un filé multicouche qui facilite une mise en correspondance de couleurs et a non seulement une haute résistance au lavage, mais également une haute résistance à la chaleur et un caractère ignifugeant, un tissu résistant à la chaleur obtenu à l'aide du filé multicouche, et un vêtement de protection résistant à la chaleur.

本発明の多層構造紡績糸(20)は、芯成分(21)が牽切紡績されたパラ系アラミド繊維糸であり、鞘成分(22)がポリベンズイミダゾール繊維を含み、鞘成分(22)はポリベンズイミダゾール繊維とメタ系アラミド繊維を含んで混紡されており、前記ポリベンズイミダゾール繊維と前記メタ系アラミド繊維は少なくとも2色の異なった色であり、前記多層構造紡績糸(20)は見掛け上前記ポリベンズイミダゾール繊維と前記メタ系アラミド繊維とは異なった色調である。本発明の耐熱性布帛は前記の多層構造紡績糸を使用したものであり、本発明の耐熱性防護服は前記耐熱性布帛を使用したものである。これにより、カラーマッチングが容易で耐洗濯性が高く、かつ耐熱性及び難燃性も高い多層構造紡績糸とこれを使用した耐熱性布帛及び耐熱性防護服を提供する。
