[0027] see figure 1 , present embodiment provides a kind of production method of bamboo fiber sanitary napkin, the production method of this bamboo fiber sanitary napkin comprises the steps:

[0028] On the non-woven fabric layer 110, an opening 120 penetrating through the surface 111 and the bottom surface 112 of the non-woven fabric layer 110 is opened;

[0029] Wherein, the opening 120 is set as an open type, the necking on the opening 120 is set on the bottom surface 112 of the non-woven fabric layer 110, and the opening on the opening 120 is set as the non-woven The surface 111 of the cloth layer 110 .

[0030] In the process of use, at first the surface 111 of the non-woven fabric layer 110 contacts the liquid, after the surface 111 of the non-woven fabric layer 110 contacts the liquid, the liquid begins to penetrate from the side of the opening 121 on the hole 120, due to The area of ​​the opening 120 on one side of the opening 121 is relatively large, so that the liq...

Abstract

The invention provides a production method of bamboo fiber sanitary napkins and belongs to the field of water-absorbing materials. The production method includes the following steps: arranging openingholes penetrating the surface and bottom of a non-woven fabric layer in the non-woven fabric layer, wherein the opening holes are arranged as open types, the necking ports of the opening holes are arranged at the bottom of the non-woven fabric layer, and the opening ports of the opening holes are arranged at the surface of the non-woven fabric layer. During using, as the areas of the opening holes on the opening port sides are large, liquid can quickly spread around the opening holes, so that the integral intensity of the non-woven fabric layer can be effectively guaranteed, and the insufficient structural intensity of the non-woven fabric layer due to excessively large opening holes cannot be caused; and thus, the open-type opening holes can effectively accelerate the spreading speed ofthe liquid on non-woven fabrics under the circumstances of guaranteeing the structural intensity of the non-woven fabrics.

Description

technical field [0001] The invention relates to the field of water-absorbing materials, in particular to a production method of bamboo fiber sanitary napkins. Background technique [0002] Most of the sanitary napkins on the market are mostly made of chemical fiber materials, which are non-degradable and non-renewable, and have chemical residues, which have adverse effects on human skin and even health. However, the surface layer of related products is not uniform, which will accelerate liquid penetration and not form a diffusion area. All liquid may be concentrated in the middle of sanitary napkins and paper diapers. Due to the high reverse osmosis performance of the material, the liquid reverse osmosis is caused, and the non-dry phenomenon is serious. Contents of the invention [0003] The object of the present invention is to provide a kind of production method of bamboo fiber sanitary napkin, and it can make liquid permeate rapidly in the process of using. [0004] E...
