Paperless ultra-thin and ultra-soft core

Abstract

The invention provides a paperless ultra-thin and ultra-soft core. The paperless ultra-thin and ultra-soft core comprises a spunlace cloth layer, a bulking cloth layer and a hot rolled cloth layer or a melt-spinning cloth layer from top to bottom sequentially, wherein adhesive layers are arranged on the upper surface and the lower surface of the bulking cloth layer in a spray coating manner; a plurality of water absorption factors are scattered on the adhesive layers of the bulking cloth layer; the spunlace cloth layer is glued on the upper surface of the bulking cloth layer; the hot rolled cloth layer or the melt-spinning cloth layer is glued on the lower surface of the bulking cloth layer. According to the paperless ultra-thin and ultra-soft core, commonly used dust-free paper is replaced, spunlace cloth is applied to the upper layer, hot rolled cloth or melt-spinning cloth is applied to the lower layer, furthermore, the quantity of the sprayed adhesive is reduced, so that the whole core is thinner and touches softer, product quality is improved, and a user has more comfortable experience when the core is applied to nursing materials. Compared with products such as the first three generations of diapers and the like which mainly depend on paper, the product takes non-woven fabric as a main material, therefore, a qualitative leap of the product quality is realized, and the grade is substantially improved.

Description

【Technical field】 [0001] The invention relates to the field of human body care products such as diapers and sanitary napkins, especially the core body of the care products. 【Background technique】 [0002] Nursing products such as diapers and sanitary napkins have become indispensable in people's lives. Because they are in direct contact with the human body, consumers have higher and higher requirements for the quality of their products, especially in order to have a better comfort experience. Higher requirements are placed on the thickness and softness of sanitary care products. [0003] The core is the main part of hygiene care products, the quality of the core determines the performance of the whole product. The current cores are made of dust-free paper and bulky cloth. Dust-free paper has good water absorption and water retention properties, so it is widely used in care products. [0004] The raw material of dust-free paper is wood pulp fiber, which is produced by air-...

AI Technical Summary

Problems solved by technology

Although dust-free paper has good water absorption, in order to ensure sufficient strength and prevent glue seepage, it needs a thicker thickness. Among the thinnest cores, the thickness of dust-free paper can only reach 45 grams per square meter Rice, not only the amount of raw materials is large, but also the product is thicker and less flexible, resulting in poor user experience, and the quality of the product cannot be improved.
