preparation example Construction

[0086] A method for preparing a combined spunlace nonwoven fabric, comprising the following steps:

[0087] 1) Send the raw materials of the second fiber layer into the unloading tank in proportion to disperse the fibers to make a fiber slurry with a concentration of 0.1-1wt%; remove impurities and fiber clusters, so that the fibers in the fiber slurry are in a single fiber state .

[0088] 2) After the fiber slurry is stirred and diluted, it is sent to the inclined wire former through the slurry pump, and the second fiber layer is made after being netted, formed and dehydrated; the second fiber layer is placed on the forming wire.

[0089] 3) After the raw materials of the first fiber layer are fed in proportion, the first fiber layer is made through the processes of opening, mixing and carding in sequence.

[0090] 4) The first fiber layer is introduced onto the hydroentangled screen, and then the second fiber layer is peeled off from the forming net and transferred to the ...

Embodiment 1

[0099] Such as Figure 1-2 As shown, a combined spunlaced non-woven fabric used for water-absorbing surface layers of personal hygiene products, including the first fiber layer and the second fiber layer connected by upper and lower layers; the first fiber layer contains mass The cotton fiber of percentage 100%; The hydrophobic fiber that contains mass percentage 100% in the described second fiber layer; The fibers in the first fiber layer and the second fiber layer are entangled with each other; The surface distribution of the first fiber layer There are several protrusions and several through holes passing through the second fiber layer; the opening area of ​​the through holes on the top surface of the first fiber layer is larger than the opening area on the bottom surface of the second fiber layer.

[0100] The opening ratio of the through-holes is 35%; the protrusions and the through-holes are alternately arranged and distributed; the conventional moisture regain of the hy...

Embodiment 2

[0116] A combined spunlace non-woven fabric used for the water-absorbing surface layer of personal hygiene care products, including a first fiber layer and a second fiber layer connected by upper and lower layers; the first fiber layer contains 80% by mass Hydrophilic fibers and 20% polyester fibers; the second fiber layer contains 90% by mass percentage of hydrophobic fibers and 10% ultra-short viscose fibers; the first fiber layer, the second fiber layer The fibers of the first fiber layer are entangled with each other; the surface of the first fiber layer is distributed with some protrusions and some through holes that go through the second fiber layer; the opening area of ​​the through holes on the top surface of the first fiber layer is larger than that on the bottom surface of the second fiber layer of the opening area.

[0117] The porosity of the through-holes is 45%; the protrusions and the through-holes are alternately arranged and distributed; the conventional moist...

Abstract

The invention relates to the technical field of spunlace non-woven, and discloses a combined spunlace non-woven fabric for a personal hygiene nursing product water absorption surface layer and a preparation method of the non-woven fabric. The spunlace non-woven fabric comprises a first fiber layer and a second fiber layer, the first fiber layer comprises hydrophilic fibers, the second fiber layercomprises hydrophobic fibers, the fibers in the first fiber layer and the second fiber layer are entangled each other, a plurality of projections and a plurality of through holes are distributed on the surface of the first fiber layer, and the through holes penetrate the second fiber layer. The non-woven fabric comprises double-layer fibers with different solution absorption performances, one surface contacting with human skins has hydrophilicity, softness and skin-friendly performance of the fabric cannot be affected, the other surface without contacting with the human skins has hydrophobicity, so that ratio of hydrophilic fibers can be reduced, liquid storage amount of the surface layer is reduced, liquid absorbed by the first fiber layer can rapidly pass the second fiber layer to entera flow guide layer, and dry and comfortable performances of surface layer materials are improved.

Description

technical field [0001] The invention relates to the technical field of spunlace nonwovens, in particular to a combined spunlace nonwoven fabric used for water-absorbing surface layers of personal hygiene care products and a preparation method thereof. Background technique [0002] Existing spunlace non-woven fabrics are mainly made of textile fibers such as viscose and polyester as raw materials through mechanical carding and high-pressure jet spraying. Since the fiber is processed by the spunlace process, the fiber will not be rigidly squeezed and damaged, so that the physical and mechanical properties of the fiber will not be affected, and the inherent softness of the fiber net will be maintained to the greatest extent. Therefore, water Pricked nonwovens are widely used in the field of personal hygiene care. [0003] General personal hygiene care products (such as sanitary napkins, diapers, etc.) are usually composed of a surface layer, an inner absorbent layer and an ant...
