Abstract

The invention relates to dust-free paper of a stratified structure, and further relates to a manufacturing method and purposes of the dust-free paper. The dust-free paper is high in product density, small in thickness, and excellent in liquid absorbing performance. The manufacturing method utilizes multi-group press polish processes, a large number of composite fibers are not needed, no water or steam is additionally needed to be added into paper sheets, the thin dust-free paper which is high in density and good in adhering effect can be obtained, and existing production processes are simplified.

Description

technical field [0001] The invention relates to the field of dry papermaking, in particular to a thin dust-free paper with a new structure for liquid absorption, a manufacturing method including multiple calendering processes 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...
