Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
The present embodiment will be described in detail with reference to fig. 1 and 2. The dry and comfortable skin-friendly spunlace composite nonwoven fabric comprises a skin-friendly surface layer 1, a hot air nonwoven fabric layer 2 and a liquid storage fiber layer 3 which are sequentially arranged and reinforced and compounded through spunlace.
The fiber used in the skin-friendly surface layer 1 is superfine polylactic acid fiber, and the fineness of the superfine polylactic acid fiber is 2.7-9.07um. The polylactic acid fiber has good antibacterial and skin-friendly effects, and the superfine fiber enables the skin-friendly surface layer 1 to be soft in handfeel, so that the skin-friendly effect is further improved.
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 hot air non-woven fabric layer 2. The production rate of the skin-friendly surface layer 1 can be improved by arranging the parallel lapping and the cross lapping in two lapping modes. Also in this embodiment, the ultra-fine polylactic acid fiber cross-laid layer 12 is located outside and is in contact with the skin of the user when in use. Basically all fibers in the superfine polylactic acid fiber parallel lapping layer 11 are arranged in parallel, so that a good flow guide effect can be achieved. So that the body fluid can be guided to other positions and does not gather at one position.
The hot air non-woven fabric layer 2 is made of sheath-core polylactic acid fibers, the sheath-core polylactic acid fibers comprise a high-melting-point PLA polymer layer 21 and a low-melting-point PLA polymer layer 22, the low-melting-point PLA polymer layer 22 is coated outside the high-melting-point PLA polymer layer 21 to form a sheath-core structure, the high-melting-point PLA polymer layer 21 and the low-melting-point PLA polymer layer 22 are coaxially or eccentrically arranged, and a plurality of water guide grooves 221 are further formed in the surface of the low-melting-point PLA polymer layer 22. The skin-core structure can gradually form a three-dimensional curling shape in the process of heating and reinforcing, so that the cloth layer has certain bulkiness, the flow guiding effect is good, body fluid can be helped to quickly seep downwards, and meanwhile, when the cloth layer is used as a surface layer of a paper diaper, the air permeability of the paper diaper can be better, so that the young and tender skin of an infant can be effectively protected; the flow guide effect is further improved by arranging the plurality of water guide grooves on the outer surface of the low-melting-point polymer layer.
. Further, the depth of the water guiding groove 221 is one third to one half of the thickness of the low melting PLA polymer layer 22. In this embodiment, one-half is selected.
The cross section of the fiber used by the liquid storage fiber layer 3 is C-shaped. 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 communicate with the outside, when in use, the fiber can store liquid inside. So that body fluid can no longer penetrate downwards.
Example two
This embodiment will be described in detail with reference to fig. 3 and 4. The difference between the dry and comfortable skin-friendly spunlace composite nonwoven fabric related to the embodiment and the embodiment one is that: and a liquid absorption fiber layer 4 is compounded on one side of the liquid storage fiber layer 3, which is far away from the hot air non-woven fabric layer 2. The fibers used by the liquid absorption fiber layer 4 are viscose fibers or wood pulp fibers. In this embodiment, wood pulp fibers are selected, i.e., the liquid-absorbent fibrous layer 4 is a wood pulp spunlace. When the body fluid is more, the body fluid absorbed by the liquid storage fiber layer 3 has an upper limit value, and when the body fluid exceeds the upper limit value, the body fluid can permeate downwards, and the liquid absorption fiber layer 4 is arranged to absorb the redundant body fluid.
Another difference from the first embodiment is that: the C-shaped structure is formed by connecting four small circles with the circle centers positioned on the same circle, two ends of the C-shaped structure are respectively provided with one small circle, and the bottom of the C-shaped structure is provided with two small circles; the hollowness of the C-shaped section fiber is 20-50%.
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 principles of this invention. 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.
