Description
Technical Field
The invention relates to the technical field of textiles, in particular to a fixed-point consolidation double-layer 3D fabric and a manufacturing process thereof.

The hot air non-woven fabric is formed by uniformly distributed thermoplastic double-component fiber nets through hot air setting. In order to make raised patterns on the surface of the hot-air non-woven fabric, the conventional method is to roll the patterns on the hot-air non-woven fabric which is already subjected to heat setting by using a compression roller with concave-convex patterns, and then perform secondary hot-air setting on the non-woven fabric. The method must use a fiber web with secondary plasticity as a raw material, and the hot air non-woven fabric which is already subjected to heat setting is subjected to rolling and secondary hot air setting, so that the bulkiness of the hot air non-woven fabric is damaged, the softness is reduced, and the requirements of consumers on the increasingly improved comfort and softness cannot be met.
The utility model patent with the patent number of CN201420444147.5 and the name of 'hot-air non-woven fabrics airflow carving equipment' discloses a method for making patterns on hot-air non-woven fabrics by utilizing sprayed airflow.

Although the method overcomes the defects of roller pressing and secondary hot air shaping, the height of the pattern protrusions is very small, and the stereoscopic impression is not obvious.
The patent No. CN201810357722.0 entitled "method and equipment for manufacturing hot-air non-woven fabric" discloses a method for manufacturing hot-air non-woven fabric, which comprises opening and carding fiber raw materials to form a fiber web, passing the fiber web through a mold with concave patterns before the fiber web is heat-set, adsorbing the fiber web by the concave patterns on the mold, gathering and filling fibers of the fiber web into the concave patterns to form raised bulges with the same shape as the concave patterns, transferring the fiber web with the bulges to an oven, heating, setting and cooling to obtain the hot-air non-woven fabric, wherein the bulges are set into three-dimensional patterns protruding out of the surface of the hot-air non-woven fabric. The method overcomes the defect of secondary hot air shaping by rolling with a compression roller, has relatively good stereoscopic impression, and has low pattern retention.
