Problems solved by technology

[0009] In addition to water absorption, another disadvantage compared to wood pulp fiber SAF is that the fiber itself has a hard hand feel and poor skin feel, that is, the surface hand feel is not good
In addition, due to the rapid water absorption characteristics of SAF, the surface of products added with SAF is easy to absorb moisture and become sticky, which is difficult to store and inconvenient to use

Abstract

The invention relates to dust-free paper. The dust-free paper is of a layered structure, wherein the dust-free paper containssuper absorbent fibers and super absorbent polymer. The invention further relates to a manufacture method of the dust-free paper, and applications of the dust-free paper. According to the dust-free paper provided by the invention, SAF (Super Absorbent Fiber) and SAP (Super Absorbent Polymer) are simultaneously applied to the dust-free paper through special structure arrangement and compounding of different ingredients in each layer of the structure, the SAF and the SAP not only can express liquid absorption features and but also can be interplayed with each other, so that the disadvantages of the SAF and the SAP are remedied. The manufacture method of the dust-free paper, provided by the invention, is improved based on the existing process conditions and is suitable for the production of the dust-free paper consisting of specific ingredients, and the difficulties in the manufacture process caused by high water absorbency of the SAF are solved. According to the novel use of the dust-free paper provided by the invention, the field of absorbing materials is expanded, and the obtained dust-free paper has very wide applicability.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a dust-free paper with a new structure for liquid absorption, a manufacturing method and its application. Background technique [0002] Dry-laid papermaking technology is a new method of producing non-woven fabrics with wood pulp fibers a few millimeters long as the main raw material, through air-laid and different consolidation methods. Its products are often called expanded core materials or dust-free paper, etc. (hereinafter collectively referred to as dust-free paper). Dry papermaking technology can produce materials with different thickness, different softness, and different hygroscopicity. Its products are mainly used as absorbent core materials for disposable sanitary products such as diapers, women's hygiene products, and adult incontinence products. Used in the production of wet wipes, wipes, food pads (such as fish pads, meat pads, etc.), moisturizing (such as facial masks),...
