FIELD: personal use articles. ^ SUBSTANCE: invention refers to astronaut flight clothing. Warm flight underwear for astronaut is made from double-layer knitted fabric, which has internal and external layer. Internal layer is made from natural silk twisted fibres. External layer is made of physically modified cotton-like polyamide complex textured plied twines. Physically modified cotton-like polyamide complex twisted fibres consist of elementary profiled fibres, having stretch indices of modification of transverse section geometric form within the limits: filing degree 0.3410%, deformation degree 1.810%, branching degree 7510%, irregularity degree 1.4510%. ^ EFFECT: warm flight underwear for astronaut has high hygienic, properties, is wear-resistant, comfortable and does not release dust in form of little fibre particles in the process of wearing, and thus doesn't irritate skin surface and nasopharynx and human breathing passages. ^ 3 ex |
