FIELD: fabric used in aircraft industry for manufacture of wing and tail covering of plane. ^ SUBSTANCE: fabric is produced from warp and weft polyester complex filaments having similar linear density ranging between 27.7-29.4 tex and twist rate of 130-160 twists/min. Warp to weft filament ratio of fabric is 55-50:45-50. Fabric is produced by twill weave and is not subjected to final finishing procedure. ^ EFFECT: provision for stretching of covering owing to thermal shrinkage of proposed fabric structure, reduced weight, and prolonged service life of fabric. ^ 3 cl, 1 tbl, 7 ex |
