BALLISTIC PROTECTION CLOTH AND PACK BASED ON BALLISTIC PROTECTION CLOTH Russian patent published in 2001 - IPC

FIELD: textile industry. SUBSTANCE: cloth is manufactured from high-strength aramide threads of equal linear density in warp and weft directions, similar longitudinal configuration and equal number of threads per unit of width in both directions and twisting rate not exceeding 4. Cloth is manufactured by satin, twill or wafer weave of single threads and satin, twill, calico or wafer weave of 2-6 threads in warp and weft directions. Regular satin weave has pattern repeat of 5-10 with constant shift of from 2 to 7 and irregular satin weave has pattern of 4 to 10 with variable shift of from 1 to 8. Twill weave has 1-8 warp overlappings and 2-8 weft overlappings. Wafer weave pattern repeat has 4-16 threads. Pack of ballistic protection cloth has front and rear cloth layers arranged in succession and manufactured from high-strength aramide threads. Layers are arranged so that front and rear layers with respect to source of destructive force are manufactured from cloths having threads reinforced 2-6 times in warp and weft directions. Cloth pattern repeat and thread reinforcement in cloths in direction from front to rear layers is decreasing, with separating layers being arranged in front of rear layers and/or between rear layers, and/or behind rear layers. Cloth of such structure has improved puncture resistance. EFFECT: wider operational capabilities, increased efficiency and enhanced reliability in operation. 3 cl, 3 dwg, 1 tbl, 5 ex
