Problems solved by technology

[0021] Moreover, due to the open-cell structure of conventional sponge (polyurethane soft foam), it is difficult to achieve LOI greater than 27% in flame retardancy, while maintaining excellent mechanical properties and environmental performance, and the environmental protection, flame retardancy, and cost of flame-retardant textile composites. It is not easy to balance

Abstract

The invention discloses a flame-retardant single-faced velvet composite fabric, which comprises a flame-retardant surface layer and flame-retardant single-faced velvet. The fire-retardant surface layer is flame-retardant PVC artificial leather, phosphorus-containing flame-retardant polyurethane synthetic leather, or flame-retardant fabric prepared from a phosphorus-containing flame-retardant polyester polymer material, wherein the LOI is not less than 27%. The flame-retardant single-faced velvet is prepared from a phosphorus-containing flame-retardant polyester polymer material. Gram weight ofthe flame-retardant single-faced velvet is 150-450 g / m<2>, velvet height is 1-10 mm, and the LOI is not less than 27%. The composite fabric of the invention has good flame-retarding effect, comfortable and soft hand feeling, good resilience, wide application range and good dimensional stability. The composite fabric has characteristics of dry cloth, environmental protection, low smoke and low toxicity, low VOC, low atomization value, no odor, soft hand feeling, excellent flame retardant performance, high peeling strength, good resilience, comfortable hand feeling and good heat preservation. The composite fabric is applicable to seats, ceilings, door panels, safety seats, sofas, soft chairs and deck chairs for high-speed railway, bullet trains, suburban railway, coaches and cars.

Description

technical field [0001] The invention relates to the field of flame-retardant materials, in particular to a flame-retardant single-face fleece composite fabric and its preparation method and application. Background technique [0002] In recent years, traffic interior combustion accidents have occurred frequently, especially for textile composites or leather composites with upholstered fillings. Cases of mass deaths and injuries caused by fires are not uncommon. It is imminent to improve the flame retardant performance of composite fabrics in the application fields of high-speed rail, bullet train, urban railway, passenger car, car seat, ceiling, door panel, safety seat, sofa, soft chair, recliner and so on. [0003] The combustion test standard for vehicle interior materials is one of the important factors to ensure vehicle safety. All countries have clear regulations on the flammability of automotive interior fabrics. my country has proposed new standards on the flame retar...
