Problems solved by technology

This technical solution can only be applied to knitted and woven products, and because the inner and outer yarns are made of different materials, their air permeability and comfort are relatively poor; while light and thin cotton products such as cotton spunlace non-woven fabrics Among them, in view of the strong water absorption performance of cotton fiber, it is very difficult to realize the unidirectional moisture transfer function, and the layered technical solution is difficult to meet the requirements of light and thin products

[0027] like figure 1 As shown, the all-cotton spunlace nonwoven matrix 10 consists of cotton fibers 13 entangled with each other. The all-cotton spunlace non-woven fabric base 10 has a hydrophobic surface 11 and a hydrophilic surface 12, wherein the hydrophobic surface 11 contains a hydrophobic substance. In this embodiment, the surface of the cotton fibers 13 located on the hydrophobic surface 11 is covered with a hydrophobic film layer, which contains nano wool particles 14 . These wool particles 14 are actually nano wool protein particles extracted from natural wool in a certain way. Compared with the fiber 13, its hydrophilic performance is reduced, so an additional pressure difference is generated between the hydrophobic surface 11 and the hydrophilic surface 12 to form a differential capillary effect, and the moisture in contact with the hydrophobic surface 11 can be unidirectionally transported along the cotton fiber 13. The water surface 12 avoids the backflow of moi...

[0029] In this embodiment, the hydrophobic substance contained in the hydrophobic surface 11 of the all-cotton spunlace non-woven fabric is a hydrophobic film layer distributed on the hydrophobic surface 11 in a mesh shape, and contains nano wool particles 14 therein. In this embodiment, the cotton spunlace non-woven fabric can be finished by using the nano wool emulsion by flat screen printing. Only the surface of the cotton fibers 13 in the printing area is covered with a hydrophobic film layer. The hydrophobic surface 11 of the spun cloth substrate forms a regular or irregular mesh pattern, and is interlaced with the exposed areas formed by the cotton fibers 13 without the hydrophobic film layer, for example, it can be designed as a densely distributed porous pattern (including round holes, squares, etc.). holes, etc.), grid patterns, etc.

[0030] like figure 2 and image 3 As shown, in this embodiment, the printing area 111 forms a certain square grid pattern on the hy...

[0034] like Figure 4 As shown, when the hydrophobic substance is a nano-wool emulsion containing nano-wool particles 14, or is called a nano-wool protein emulsion, the unidirectional wet-conducting cotton spunlace non-woven fabric manufacturing method of the present embodiment comprises the following steps:

[0035]Step S101 : spray the nano wool emulsion on one side of the cotton spunlace non-woven fabric substrate 10 through a spraying process, so that the nano wool emulsion is coated on the surface of the cotton fiber 13 of the hydrophobic surface 11 to form a hydrophobic film layer. The average particle size of the particles is nanoscale, eg 75 nm. The amount of spraying and process parameters are controlled according to specific needs, and try to ensure that the nano wool emulsion will not penetrate into the hydrophilic surface 12 of the base 10 of the cotton spunlace non-woven fabric.

[0036] Specifically, the nano-wool emulsion of this embodiment can be obtained by t...

Abstract

The invention discloses a one-way moisture-transfer all-cotton spunlaced nonwoven and as well as a product and a preparation method thereof. The all-cotton spunlaced nonwoven comprises an all-cotton spunlaced nonwoven matrix, the all-cotton spunlaced nonwoven matrix comprises a hydrophobic surface and a hydrophilic surface, wherein the hydrophobic surface contains hydrophobic substances used for transferring moisture from the hydrophobic surface to the hydrophilic surface. The one-way moisture-transfer all-cotton spunlaced nonwoven selects an all-cotton material, has light and soft texture and good one-way moisture-transfer effect and can effectively absorb and permeate the moisture and prevent the moisture from reversely flowing, thereby enabling the hydrophobic surface directly contacting with the skin of a human body to keep dry and bringing about more comfortable feeling for a user of a one-way moisture-transfer product.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a unidirectional wet-conducting cotton spunlace non-woven fabric, a product and a manufacturing method thereof. Background technique [0002] Cotton is a natural cellulose fiber with good hygroscopicity, air permeability and comfort, but the hygroscopicity of cotton fiber itself leads to a certain moisture regain. People wear ordinary cotton spunlace non-woven fabrics for clothing or other products. During exercise, the heat and sweat generated in the body are discharged through the skin and conducted to the inner surface of the clothes. The moisture in the sweat is absorbed by the cotton fibers and cannot be discharged in time, resulting in the clothes clinging to the skin of the human body and causing sticky and wet inconvenience. comfortability. [0003] It has been found by research that if the non-woven fabric is subjected to unidirectional moisture-guiding finishing, moist...
