▎ 摘　　要

NOVELTY - Warm-keeping polyester composite elastic fiber fabric comprises insulating inner layer (1), middle layer (2) and surface layer (3). The insulating inner layer is made of nitrile chloride fiber material yarn. The middle layer is made of porous heating polyester fiber material yarn. The surface layer is made of warm polyester composite elastic yarn. The spandex filament is prepared. USE - Warm-keeping polyester composite elastic fiber fabric. ADVANTAGE - The warm-keeping polyester composite elastic fiber fabric uses the nitrile chloro fiber material yarn made of warm inner layer except for keeping warm, it also has good flame retardance; the middle layer made of porous heating polyester fiber material yarn, the product has good moisture absorption performance, realizing quick absorption of water evaporated in the body; the surface layer is made of warm-keeping polyester composite elastic yarn; the spandex filament is made of excellent ventilation effect, and added with graphene material, so that the composite fabric has good heat preservation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a thermal insulation polyester composite elastic fiber fabric, which involves gray cloth-boiling and bleaching-dyeing-washing-fixing-washing-out vat-dehydration-softening-drying-stentering-inspection-rolling. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of warm-keeping polyester composite elastic fiber fabric. Insulating inner layer (1) Middle layer (2) Surface layer (3)
