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 and stability of the connection between the wear-resistant coating with such a structure and the non-woven fabric are not high, and at the same time it is necessary to improve the air permeability and moisture removal performance

Abstract

The invention discloses a non-woven fabric with a stable structure and a preparation method thereof. The non-woven fabric comprises a non-woven fabric core layer, skeleton twisted fiber yarns and a surface coating; the skeleton twisted fiber yarns are formed by spirally winding spandex elastic fibers on the surfaces of bamboo fiber yarns, and due to the elastic characteristic of the spandex elastic fibers, after the bamboo fiber yarns are connected to multiple connecting protruding strips and multiple connecting strip-shaped grooves in a penetrating mode, the spandex elastic fibers can be elastically tightened to be connected to the multiple connecting protruding strips in a penetrating mode, in this way, the structures of the multiple connecting protruding strips of the non-woven fabric core layer are in the tendency of being elastically tightened and expanded, and then the structures of the multiple connecting protruding strips of the non-woven fabric core layer are more stable.

Description

technical field [0001] The invention relates to a structurally stable 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 and stability of the connection between the wear-resistant coating of such a structure and the non-woven fabric are not high, and at ...
