HIGH-STRENGTH AND LOW-INFLAMMABILITY FABRIC Russian patent published in 1998 - IPC

FIELD: fabric used for manufacture of soft enclosure for rescue and general-purpose pressure suits, altitude compensating suits for flyers and fireproof textile articles. SUBSTANCE: fabric has twisted combined threads containing complex threads and yarn. Fabric has interweaving density coefficient of 0.54-1, surface density of 60-450 g/sq m and weft and warp density ratio of 0.5-2. Fabric warp or weft contains twisted combined threads with nominal linear density of 14.3-169.8 tex and twisting density of 20-450 twists per meter. These threads have complex threads and single and/or twisted yarn based on aromatic heterochain polymers - polyheteroarylenes. Fabric warp or weft may further contain natural and/or artificial and/or synthetic threads manufactured from nonthermostable polymers and/or complex threads and/or yarn from thermostable polymers or their combination and/or threads containing mixture of natural, artificial, synthetic filaments, thermostable filaments and their combinations. EFFECT: wider fields of application and improved quality of fabric. 2 cl, 1 tbl
