Problems solved by technology

Moreover, the surface coating layer is often in contact with the skin for a long time. In the existing disposable products, bacteria are often easy to breed, and there are health risks
[0003] The surface coating layer needs to have good performance in terms of air permeability, dryness and bacteriostasis, especially the dryness of the surface coating layer will directly affect the use experience of the product. The hydrophobicity of the existing surface coating layer is It meets the standard, but its moisture and water removal speed is slow, and it cannot make the user feel continuously dry. The existing cotton fabrics cannot meet the dryness requirements

[0048] Secondly, the present invention also provides a kind of preparation method of described non-woven fabric, and it comprises the steps:

[0049] S1 prepares the first nonwoven fiber web:

[0050] The raw material of the first non-woven fiber web is subjected to quantitative feeding, opening, fine opening, secondary fine opening, carding, cross-lapping, and drafting processes to obtain the first non-woven fiber web;

[0051] S2 prepares polylactic acid fiber web:

[0052] Polylactic acid fiber webs are obtained after quantitative feeding, opening, fine opening, secondary fine opening, and carding of polylactic acid fiber raw materials;

[0053] S3 The first non-woven fiber web treated in step S1 and the polylactic acid fiber web treated in step S2 are superimposed into one through hydroentanglement, soaked in a hydrophobic agent, and dried to make a finished non-woven fabric.

Embodiment 1

[0056] The bamboo fiber material is subjected to quantitative feeding, opening, fine opening, secondary fine opening, carding, cross-lapping, and drafting processes to obtain the first non-woven fiber web;

[0057] S2 prepares polylactic acid fiber web:

[0058] Polylactic acid fiber webs are obtained after quantitative feeding, opening, fine opening, secondary fine opening, and carding of polylactic acid fiber raw materials;

Abstract

The invention discloses a non-woven fabric and a preparation method thereof, the non-woven fabric comprises a non-woven fabric material, the non-woven fabric material comprises a first non-woven fabric fiber net and a polylactic acid fiber net; the first non-woven fabric fiber net is made of bamboo fibers or viscose fibers; and a hydrophobic agent is infiltrated between the first non-woven fabricfiber net and the polylactic acid fiber net. The non-woven fabric provided by the invention has natural antibacterial and degradation functions. The first non-woven fabric fiber net absorbs moisture and inhibits bacteria, and the polylactic acid fiber net resists moisture and bacteria and is soluble; and therefore one surface of the non-woven fabric has a rapid hydrophobic function, and the othersurface of the non-woven fabric has a water-blocking function.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a non-woven fabric and a preparation method thereof. Background technique [0002] Absorbent non-woven fabrics are now widely used in disposable products, such as diapers and disposable underwear. Generally, it is necessary to provide a surface covering layer, an absorbent layer and a backing layer. The surface covering layer is basically a non-woven fabric used now. The non-woven fabric of the surface covering layer needs to be breathable and dry. The breathable non-woven fabric can improve the air permeability inside the diaper, and water vapor can flow into the diaper. In addition, the timely discharge of moisture and heat can effectively reduce the occurrence of eczema, and it is soft and comfortable and basically does not irritate the skin. The surface covering that is in direct contact with the skin needs to be kept dry because healthy skin should be dry. Wet ...
