preparation example Construction

[0026] A method for preparing a pure cotton one-way flow guide material, comprising: a compounding step: compounding a hydrophilic cotton material 3 and a water-repellent cotton material 1 to obtain a pure cotton one-way flow guide material. The water-repellent cotton material 1 is covered on the hydrophilic cotton material 3 in the pure cotton one-way guide material, and part of the cotton fibers of the hydrophilic cotton material 3 extend into the cotton fibers of the water-repellent cotton material 1 to absorb moisture Quickly download. Wherein, the mass proportion of the hydrophilic cotton material 3 is smaller than that of the water-repellent cotton material 1 .

[0027] The preparation method of the above-mentioned pure cotton unidirectional flow-conducting material, because the hydrophilic cotton material 3 and the water-repellent cotton material 1 are combined into one structure, and the hydrophilic fibers and the water-repellent fibers are interlaced, can instantly fo...

Embodiment 1

[0042] A preparation method of pure cotton unidirectional flow guide material, comprising:

[0043] Unwinding step: unwinding operation of hydrophilic cotton spunlace nonwoven fabric and water repellent cotton spunlace nonwoven fabric, the unwinding speed is controlled at 35m / min.

[0044] Composite step: After the unwinding step, the hydrophilic cotton spunlace non-woven fabric and the water-repellent cotton spunlace nonwoven fabric are composited by high-pressure spunlace to obtain a pure cotton unidirectional flow guide material. The pressure of a single waterjet head is 90bar.

[0045] Among them, the mass ratio of hydrophilic cotton spunlace nonwoven fabric and water repellent cotton spunlace nonwoven fabric is 1:1.5.

[0046] Both the hydrophilic cotton spunlace nonwoven fabric and the water repellent cotton spunlace nonwoven fabric have a mesh structure. The hydrophilic mesh 31 on the hydrophilic cotton spunlace non-woven fabric is smaller than the water-repellent mes...

Embodiment 2

[0049] A preparation method of pure cotton unidirectional flow guide material, comprising:

[0050] Unwinding step: Water-repellent cotton spunlace non-woven fabric is used for unwinding operation, and the unwinding speed is controlled at 35m / min.

[0051] Carding step: the hydrophilic cotton fiber is combed into a hydrophilic cotton web.

[0052] Composite step: after the unwinding operation, the water-repellent cotton spunlace non-woven fabric and the hydrophilic cotton net are composited by high-pressure spunlace to obtain a pure cotton one-way flow-conducting material. The pressure of a single hydrojet head is 70bar.

[0053] Among them, the mass ratio of hydrophilic cotton net and water-repellent cotton spunlace nonwoven fabric is 1:3.

[0054] Both the hydrophilic cotton net and the water-repellent cotton spunlace nonwoven fabric have a mesh structure. The hydrophilic mesh 31 on the hydrophilic cotton net is smaller than the water-repellent mesh 11 on the water-repell...

Abstract

The invention discloses a unidirectional pure cotton flow-guide material, a preparation method thereof, and a product. The preparation method comprises a compounding step of compounding a hydrophiliccotton material with a water-repellent cotton material to obtain the unidirectional pure cotton flow-guide material. The water-repellent cotton material in the unidirectional pure cotton flow-guide material covers the hydrophilic cotton material, and a part of hydrophilic cotton fibers stretch into water-repellent cotton fibers, and is used for rapidly guiding downwards water. The mass proportionof the hydrophilic cotton material is less than the mass proportion of the water-repellent cotton material. Because the hydrophilic cotton material and the water-repellent cotton material are compounded and combined into an integrated structure, the hydrophilic fibers and the water-repellent fibers are mutually staggered, a liquid in a water-repellent layer can be rapidly conducted to a hydrophilic layer, and a water flow channel is instantaneously formed, so that rapid infiltration is achieved. The mass proportion of the hydrophilic cotton material is less than the mass proportion of the water-repellent cotton material, and the material achieves a good balance point in the aspects of hydrophilicity and water repellency, so that the dry-touch feeling of the surface layer of the material can further be ensured.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a pure cotton unidirectional flow guide material, a preparation method and a product thereof. Background technique [0002] More than 99% of the surface materials of sanitary products on the market are composed of chemical fibers, and we all know that chemical fibers have static electricity, and are prone to induce allergies and eczema, especially many chemical substances are added in the production process of chemical fibers, which are harmful to the skin. It is highly irritating, and chemical fibers are difficult to degrade; in daily life, we choose pure cotton materials when we buy underwear, especially underwear. With the improvement of people's living standards and consumption concepts, consumption Consumers hope to use more comfortable, safe and environmentally friendly products. Therefore, it is necessary to study adding degradable regenerated cellulose or cotton to the surface la...
