Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described with reference to fig. 1. The superfine fiber spunlace composite non-woven fabric related to the embodiment comprises a skin-friendly surface layer 1 and a flow guide fiber layer 2 which are composited through spunlace; a liquid storage fiber layer 3 is compounded on one side of the flow guide fiber layer 2, which is far away from the skin-friendly surface layer 1; and a water-repellent non-woven fabric layer 4 is compounded on one side of the liquid storage fiber layer 3 away from the flow guide fiber layer 2.

The skin-friendly surface layer 1 is a superfine polylactic acid fiber net, and further, the fineness of the superfine polylactic acid fibers in the skin-friendly surface layer 1 is 2.7-9.07um. The polylactic acid fiber has good skin-friendly and bacteriostatic functions and can be directly contacted with the skin of a human body. And the adopted superfine polylactic acid fiber has soft touch, so that the use experience is further improved.

The diversion fiber layer 2 is a polylactic acid fiber net which is laid in parallel. The majority of the polylactide fibers in the parallel laid polylactic acid web are parallel to the long direction of the nonwoven. In the superfine fiber spunlace composite non-woven fabric, the polylactic acid fibers in the flow guide fiber layer 2 can guide the body fluid to the whole non-woven fabric instead of being gathered at one position. Furthermore, the cross section of the polylactic acid fiber in the flow guide fiber layer 2 is Y-shaped, cross-shaped or I-shaped. In the embodiment, the Y-shaped section is selected, so that a good flow guiding effect is achieved. Therefore, body fluid in the skin-friendly surface layer 1 can be guided very well, so that the surface of the skin-friendly surface layer 1, which is in contact with a human body, can keep dry and comfortable.

The cross section of the fiber used in the liquid storage fiber layer 3 is C-shaped, that is, the fiber used in the liquid storage fiber layer 3 is hollow and has an opening along the length direction to be communicated with the outside, and when the liquid storage fiber is used, the liquid can be stored in the fiber. So that body fluid can no longer penetrate downwards.

Further, the fineness of the fibers used in the liquid storage fiber layer 3 is 0.3-1.56dtex.

Further, the skin-friendly surface layer 1 comprises an ultrafine polylactic acid fiber parallel lapping layer 11 and an ultrafine polylactic acid fiber cross lapping layer 12; the superfine polylactic acid fiber parallel lapping layer 11 is adjacent to the flow guide fiber layer 2. The superfine polylactic acid fiber parallel lapping layer 11 also has a certain flow guiding function, and the flow guiding fiber layer 2 uses fibers with special-shaped cross sections, so that the body fluid guided by the superfine polylactic acid fiber parallel lapping layer 11 can be absorbed to the flow guiding fiber layer 2 more quickly due to the wicking effect of the fibers with special-shaped cross sections.

Example two

This embodiment will be described in detail with reference to fig. 2. In the superfine fiber spunlace composite nonwoven fabric related to the embodiment, a liquid absorption fiber layer 5 is arranged between the liquid storage fiber layer 3 and the water-repellent nonwoven fabric layer 4; the fibers used in the liquid-absorbent fibrous layer 5 are wood pulp fibers or cotton pulp fibers.

If the user excretes the body fluid when more, can upwards permeate from stock solution fiber layer 3, set up the absorption liquid fiber layer 5 this moment can be better absorb the body fluid.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
