Problems solved by technology

At present, most of the adsorption backing papers used in the domestic market are imported products. Although the quality is good, the cost is relatively high
However, most domestic products have poor air permeability. If they are used to make sanitary napkins and paper diapers, the polymer materials will absorb unevenly, which will often lead to local temperature rise, forming a humid environment, which is easy to induce various diseases, and the wet strength is low. to tear

Embodiment 1

[0011] A method for manufacturing highly air-permeable adsorption backing paper, using natural wood pulp as raw material, including the steps of pulping, desanding, flaking, papermaking, etc., said wood pulp is composed of softwood pulp and hardwood pulp, wherein Coniferous pulp accounts for 80% by weight, hardwood pulp accounts for 20% by weight, and the beating current is 320-340A; the pulp is disintegrated in a hydropulper for 15 minutes, and diluted to a concentration of 3-5% , pumped into the unknocking pulp tank to remove sand, and then into the defiberizing machine for desilting. The decompressed wood pulp enters the double disc mill. After cutting and brooming the fibers, it enters the thick white water tank and is diluted with white water. The slurry goes through the concentrated white water tank to the pressure screen to remove the larger impurities, and finally enters the headbox for online copying, and the concentration of the online copying is 0.05%. Wet strength ...

Embodiment 2

[0013] The present invention is to take bleached wood pulp as production raw material, according to the weight ratio of 90% coniferous pulp: 20% broadleaf pulp is dropped into in the hydraulic pulper, carries out pulping (hydraulic pulper volume is 8m 3 ), adding defoamer at the same time of pulping, adding 250ml per ton of paper, and adding CMC consumption according to 1.5kg / ton of paper; after disintegrating in a hydropulper for 15 minutes, dilute to a concentration of 3-5%. Pumped to the intermediate slurry tank (32m 3 ), and then use the intermediate pump to pump to the uncracked slurry tank (32m 3 ), desanding by high-concentration desander to remove impurities with large proportions such as sand and iron in the raw material; the slurry enters the deflagging machine from the unbeaten pulp, and fully decomposes the fibers, so that the fibers can be fully divided into filaments ;The decomposed wood pulp enters the ￠550mm double disc mill to cut and broom the fibers; after ...

Abstract

The present invention discloses a manufacturing method of high permeability adsorption lining paper. It uses natural wood pulp as raw materials and includes brashing pulp, desanding, easing, papermaking and other steps. It is characterized by: said wood pulp is mixed by coniferous pulp and broadleaf pulp, the weight ratio of coniferous pulp is 80-90% and thereof broadleaf pulp is 10-20%, the beating current is 320-340A and the papermaking screening concentration is 0. 05%. The adsorption lining paper prepared through the invention has good air permeability, the polymer adsorption is uniform, the wet strength is high, particularly it is suited for one-time adsorption pet supplies, such as women's sanitary napkins, baby paper diaper and pet pad.

Description

technical field [0001] The invention relates to a paper manufacturing method, in particular to a manufacturing method for producing highly air-permeable adsorption backing paper for women's sanitary napkins, baby diapers, pet pads and the like. Background technique [0002] Highly breathable absorbent liner is a disposable household paper used in the production of women's sanitary napkins, baby diapers, pet pads, etc. The above products are all made of absorbent backing paper as the bottom layer, coated with polymer water-absorbing materials, non-woven fabrics, etc. Therefore, as a carrier, the adsorption backing paper is required to have high air permeability and corresponding wet strength. At present, most of the adsorption backing papers used in the domestic market are imported products. Although the quality is good, the cost is relatively high. However, most domestic products have poor air permeability. If they are used to make sanitary napkins and paper diapers, the p...
