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.

Embodiment 1

[0018] refer to figure 1 , paperless ultra-thin ultra-soft double spunlace core body, including spunlace cloth layer 1, bulky cloth layer 2 and lower spunlace layer 3 arranged in sequence from top to bottom, the upper surface of the bulky cloth layer 2 and The lower surface is sprayed with a viscose layer, the viscose layer of the bulky cloth layer 2 is sprinkled with some water absorption factors, the spunlace cloth layer 1 is bonded to the upper surface of the bulky cloth layer 2, and the lower spunlace layer 3 is bonded to the The lower surface of the loose cloth layer 2.

[0019] The thickness of the lower spunlace layer 3 is 35-40g / m 2 , is thinner than the dust-free paper used in the prior art, and has better water diversion and water absorption. The processing technology of the lower spunlaced layer 3 is: first loosen, then card, then lay the net, then card again, and lay again The net is then spunlace, and finally dried to obtain a non-woven fabric with a spunlace la...

Abstract

The invention provides a paperless ultra-thin and super-soft double-spunlace core body comprising a spunlace layer, a fluffy fabric layer and a lower spunlace layer which are sequentially arranged from top to bottom. Viscose glue layers are sprayed on the upper surface and the lower surface of the fluffy fabric layer correspondingly. A plurality of water absorption factors are sprinkled on the viscose glue layers of the fluffy fabric layer. The spunlace layer is glued on the upper surface of the fluffy fabric layer. The lower spunlace layer is glued on the lower surface of the fluffy fabric layer. Commonly-adopted dust-free paper is replaced, the upper layer adopts spunlace, the lower layer also adopts spunlace, and meanwhile the glue spraying amount is decreased, so that the whole core body is thinner, the hand feeling is softer, accordingly, the product quality is improved, and when the core body is applied to nursing materials, users have more comfortable experience. Compared with products such as the first three generations of diapers which are mainly made of paper, the product is mainly made of nonwoven fabrics, so that the qualitative leap on the product quality is achieved, and the level is promoted greatly.

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-...
