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] Such as figure 1 As shown, the all-cotton spunlace non-woven fabric substrate 10 is composed of intertwined cotton fibers 13 . The all-cotton spunlace nonwoven fabric substrate 10 has a hydrophobic surface 11 and a hydrophilic surface 12, wherein the hydrophobic surface 11 contains hydrophobic substances. In this embodiment, the surface of the cotton fiber 13 on the hydrophobic surface 11 is coated with a hydrophobic film layer, which contains nano wool particles 14 . These wool particles 14 are actually nano-wool protein particles extracted in a certain way from natural wool. After the surface of the cotton fiber 13 on the hydrophobic surface 11 is coated with a hydrophobic film layer, this part of the cotton fiber 13 and the cotton on the hydrophilic surface 12 Compared with the fiber 13, its hydrophilic property is reduced, so an additional pressure difference is generated between the hydrophobic surface 11 and the hydrophilic surface 12 to form a differential capil...

[0029] In this embodiment, the hydrophobic substance contained in the hydrophobic surface 11 of the all-cotton spunlaced nonwoven fabric is a hydrophobic film layer distributed on the hydrophobic surface 11 in a network shape, which contains nano-wool particles 14 . In this embodiment, the nano-wool emulsion can be used to finish the cotton spunlace non-woven fabric by flat screen printing, and only the surface of the cotton fiber 13 in the printing area is covered with a hydrophobic film layer. The hydrophobic surface 11 of the woven fabric matrix forms a regular or irregular mesh pattern, and is interlaced with the exposed area formed by the cotton fiber 13 without a hydrophobic film layer, for example, it can be designed as a densely distributed porous pattern (including round holes, square holes, etc.). holes, etc.), grid patterns, etc.

[0034] Such as Figure 4 As shown, when the hydrophobic substance is a nano-wool emulsion containing nano-wool particles 14, or called a nano-wool protein emulsion, the unidirectional moisture-wicking all-cotton spunlace nonwoven fabric manufacturing method of the present embodiment includes the following steps:

[0035]Step S101: Spray the nano-wool emulsion on one side of the all-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 on the hydrophobic surface 11 to form a hydrophobic film layer, and the wool in the nano-wool emulsion The average particle size of the particles is nanoscale, for example 75nm. The amount of spraying and process parameters are controlled according to specific needs, so as to ensure that the nano-wool emulsion does not penetrate to the hydrophilic surface 12 of the all-cotton spunlace non-woven fabric substrate 10 as much as possible.

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 moisture-wicking all-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. However, the hygroscopicity of cotton fiber itself leads to a certain moisture regain. People wear ordinary cotton spunlace non-woven fabrics or other products. During exercise, the heat and sweat generated in the body are discharged through the skin and transferred to the inner surface of the clothes. The moisture in the sweat is absorbed by the cotton fibers and cannot be discharged in time, causing the clothes to cling to the skin of the human body and cause sticky and wet spots. comfortability. [0003] It has been found through research that if non-woven fabrics are treated with one-way moisture-wicking finishing, moisture such as sweat c...
