Problems solved by technology

New fiber products with soft, breathable and planar structure have the advantage of not producing lint; however, in some areas where non-woven fabrics are currently used, it is necessary to improve wear resistance and increase the strength of the structure, generally directly on the surface of non-woven fabrics. The surface is brushed and attached with a wear-resistant coating, but the structural strength of the connection between the wear-resistant coating and the non-woven fabric of such a structure is not high, and at the same time it is necessary to improve the breathable and moisture-wicking performance, and the non-woven fabric has poor elasticity and low wrinkle resistance

Abstract

The invention discloses a flexible and elastic skeleton supporting type non-woven fabric and a preparation method thereof. The flexible and elastic skeleton supporting type non-woven fabric comprisesa non-woven fabric inner core layer, twisted fiber yarns and surface coating. The twisted fiber yarns are formed by twisting flax fibers and polyether ester elastic fibers, the flax fibers are good intoughness and high in breaking strength, while the polyether ester elastic fibers are good in elasticity and high in crease resistance, and therefore the flax fibers and the polyether ester elastic fibers are twisted and then cooperate with each other to form a wavy framework connected to the interior of the non-woven fabric inner core layer and the interior of the surface coating in a penetrating mode; therefore, the toughness and elasticity of the whole non-woven fabric are improved, and the crease resistance is improved; and meanwhile, the structural strength of the surface coating and thenon-woven fabric inner core layer is greatly improved, and ammonium dihydrogen phosphate is added into the surface coating, so that not only can bacteria be inhibited, but also a very good fireproofand flame-retardant effect can be achieved.

Description

technical field [0001] The invention relates to a flexible and elastic skeleton-supported non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. New fiber products with soft, breathable and planar structure have the advantage of not producing lint; however, in some areas where non-woven fabrics are currently used, it is necessary to improve wear resistance and increase the strength of the structure, generally directly on the surface of non-woven fabrics. The surface is brushed and attached with a wear-resistant coating, but the structural strength of the connection between the wear-resistant coating and the non-woven fabric of such a structure is not high, an...
