Problems solved by technology
[0003] With the development of dust-free paper manufacturing process, dust-free paper can be divided into chemical bonding method and thermal bonding method according to different production processes. Among them, chemical bonding method uses wood pulp fiber (fluff pulp) After the fibers in the single fiber state are air-laid, the water-soluble adhesive is sprayed onto the surface of the fiber web by spraying method, and then baked and strengthened into cloth. Since the fiber is not beaten, it relies on the bonding effect of the adhesive when forming paper. There are disadvantages such as not smooth paper surface, easy to wrinkle, weak toughness, poor reusability and poor tear strength

Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0019] Such as figure 1 As shown, the manufacturing method of glued dust-free paper provided by the embodiment of the present invention includes the following steps: step S100, providing 100% raw wood pulp;
[0020] In step S100, the 100% raw wood pulp provided is in a solid roll shape, such as paddle board, cardboard, etc. Since the raw wood pulp is completely extracted from wood and is non-toxic and harmless to use, it is environmentally friendly and safe. In this way, by 100 The paper made of raw wood pulp does not need to add any chemical bleaching agent or fluorescent agent. It conforms to the new concept of healthy, natural, safe, degradable and environmentally friendly paper. The factors to be considered in choosing raw wood pulp are: whether it is processed (after Sof...

Abstract
The invention belongs to the technical field of airlaid papermaking and provides a making method of glued airlaid paper. The making method comprises steps as follows: (1) providing 100% original wood pulp; (2) crushing the pulp into long fibers; (3) performing air forming; (4) spraying glue on the front side; (5) performing drying; (6) spraying glue on the back side; (7) performing drying; (8) discharging the paper; (9) cutting the paper. The glued airlaid paper has the advantages that the glued airlaid paper is high in toughness, recyclable, high in water absorption and degradable and does not stick to a cutter when cut.
Description
technical field [0001] The invention belongs to the technical field of dry papermaking, and in particular relates to a method for manufacturing glued dust-free paper. Background technique [0002] Airlaid Paper, also called Airlaid pulp nonwovens, is a type of drylaid nonwovens. Dust-free paper has unique physical properties, such as high elasticity, softness, excellent hand feeling and drape, high water absorption and good water retention performance, and is widely used in hygiene care products, special medical products, industrial wipes and other fields. [0003] With the development of dust-free paper manufacturing process, dust-free paper can be divided into chemical bonding method and thermal bonding method according to different production processes. Among them, chemical bonding method uses wood pulp fiber (fluff pulp) After the fibers in the single fiber state are air-laid, the water-soluble adhesive is sprayed onto the surface of the fiber web by spraying method, a...
