Method for preparing hygienic article and the hygienic article

Abstract

The invention provides a preparation method for a hygienic product. The preparation method comprises the following steps: designing a three-dimensional solid model for a desired hygienic product, wherein a pattern is designed on the three-dimensional solid model; slicing and layering the three-dimensional solid model for the hygienic product so as to obtain shaping formation of each main material layer and each bonding material layer, wherein a main material is a fibrous material, and a bonding material is at least one selected from the group consisting of an adhesive, a thermoplastic polymer and a hot melting viscous fiber; and carrying out 3D printing according to the shaping formation of each layer and allowing the fibrous material and the bonding material to be alternately sprayed so as to enable the hygienic product to be finally printed and molded, wherein the pattern is formed on the hygienic product, and the interlacing form of a pattern area is identical to the interlacing form of other areas. The invention further provides the hygienic product prepared by using the method. The method provided by the invention has a simple process and exerts no influence on the interlacing form of fibers.

Description

technical field [0001] The invention relates to a method for preparing sanitary articles and the sanitary articles prepared by the method. Background technique [0002] Hygienic products, such as household paper, wet wipes, women's sanitary products, baby diapers, etc., sometimes use embossing or printing to form patterns on the surface of sanitary products for aesthetic appearance or other reasons. [0003] Embossing can increase the surface area and thickness of hygiene products to achieve aesthetic appearance, and can also improve water absorption capacity, wet strength, abrasion resistance and wipe-cleaning performance. The pattern on the current product usually adopts hot pressing, mechanical embossing, or high-pressure water needle to puncture the fiber web. Whether it is hot pressing or mechanical embossing, it will destroy the interweaving shape of the fibers and affect its tensile force. Especially hot pressing may cause the fibers to bond and affect their water ab...

AI Technical Summary

Problems solved by technology

Whether it is hot pressing or mechanical embossing, it will destroy the interweaving shape of the fiber and affect its tensile force, especially hot pressing, it may also cause the fiber to bond, affecting its water absorption and bulkiness

However, the high-pressure water needle puncture process needs to consume a lot of water, and has strict requirements on water quality. It needs to be equipped with a set of water treatment equipment, which makes the process complicated.
