Abstract

The invention discloses a fixed-point bonding double-layer 3D fabric, which comprises a first fiber web layer, a second fiber web layer and filling fibers arranged on the first fiber web layer; the filling fibers are provided with a three-dimensional pattern part which is raised upwards, a first bonding part is arranged between the edge of the three-dimensional pattern part and the second fiber web layer, and a second bonding part is arranged between the first fiber web layer and the second fiber web layer. According to the manufacturing process of the fixed-point bonding double-layer 3D fabric, a first fiber web that is carded lapped is conveyed to a conveying device through a first web conveying curtain to form a concave-convex surface fiber web with a die shape, and the first fiber webpasses through the conveying device and receives hot melt particles added by a feeding device through fixed point feeding. The fixed-point bonding double-layer 3D fabric has good fluffiness and softness; the melting temperature of the hot melt particles is lower than that of the skin of ES (ethylene-propylene side by side) fibers, so that the heating damage to the ES fibers is reduced, and the softness of the formed fabric is guaranteed; the structural strength of a fixed-point melting part is higher than that of a non-fixed-point melting part, so that the pattern retention is increased.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fixed-point solidified double-layer 3D fabric and a manufacturing process thereof. Background technique [0002] Air-through non-woven fabrics are made of uniformly distributed thermoplastic bicomponent fiber webs that are shaped by hot air. In order to make raised patterns on the surface of the hot-air non-woven fabric, the conventional method is to use a pressure roller with a concave-convex pattern to roll out the pattern on the hot-air non-woven fabric that has been heat-set, and then perform a second pass on the non-woven fabric. Hot air setting. This method must use a fiber web with secondary plasticity as a raw material, and rolling and secondary hot-air setting of the heat-set hot-air non-woven fabric will damage the bulkiness of the hot-air non-woven fabric, reduce softness, and fail to meet the requirements. Consumers are increasingly demanding comfort and softness...
