Embodiment 1

[0031] A preparation process of a high water-absorbing and breathable paper towel base material for puerpera, comprising the following steps:

[0032] (1) Disintegration: put hardwood pulp and softwood pulp into a hydropulper respectively, add water to a concentration of 5.0wt%, and disintegrate for 10 minutes, wherein hardwood pulp accounts for 60% of the weight ratio of wood pulp raw materials, and needle Leaf wood pulp accounts for 40% by weight of the wood pulp raw material.

[0033] (2) Deslagging: The crushed hardwood pulp and softwood pulp are deslagging through the deslagging device to remove coarse and heavy impurities, so as to prevent the refiner and pump from excessive wear;

[0034] (3) Refining: the hardwood pulp and softwood pulp after deslagging are refined through a double-disc refiner, and the fibers are cut and divided into silk brooms. After being decomposed by a deflaking machine, it is sent to the pulp storage tank after refining. After refining, the deb...

Embodiment 2

[0048] A preparation process of a high water-absorbing and breathable paper towel base material for puerpera, comprising the following steps:

[0049] (1) Disintegration: Put the hardwood pulp and the softwood pulp into the hydropulper respectively, add water to a concentration of 6.0wt%, and disintegrate for 12 minutes, wherein the hardwood pulp accounts for 62% by weight of the wood pulp raw material, and the needle Leaf wood pulp accounts for 38% by weight of wood pulp raw material.

[0050] (2) Deslagging: The crushed hardwood pulp and softwood pulp are deslagging through the deslagging device to remove coarse and heavy impurities, so as to prevent the refiner and pump from excessive wear;

[0051] (3) Refining: the hardwood pulp and softwood pulp after deslagging are refined through a double-disc refiner, and the fibers are cut and divided into silk brooms. After being decomposed by a deflaking machine, it is sent to the pulp storage tank after refining. After refining, ...

Embodiment 3

[0064] A preparation process of a high water-absorbing and breathable paper towel base material for puerpera, comprising the following steps:

[0065] (1) Disintegration: put the hardwood pulp and softwood pulp into the hydropulper respectively, add water to a concentration of 7.0wt%, and disintegrate for 15 minutes, wherein the hardwood pulp accounts for 65% of the wood pulp raw material by weight, and the Leaf wood pulp accounts for 35% by weight of the wood pulp raw material.

[0066] (2) Deslagging: The crushed hardwood pulp and softwood pulp are deslagging through the deslagging device to remove coarse and heavy impurities, so as to prevent the refiner and pump from excessive wear;

[0067] (3) Refining: the hardwood pulp and softwood pulp after deslagging are refined through a double-disc refiner, and the fibers are cut and divided into silk brooms. After being decomposed by a deflaking machine, it is sent to the pulp storage tank after refining. After refining, the deb...

Abstract

The invention relates to the technical field of tissue processing, in particular to a preparation technology of a high-water-absorption breathable tissue raw paper material for puerperae. The preparation technology comprises the following steps of pulping, residue removal, pulp grinding, pulp preparing, sizing, papermaking and rewinding. By softening a coating and adding a water-based stripping agent, the wrinkling efficiency of a drying cylinder in the papermaking process is improved, so that the elongation rate of raw paper reaches 20-25%, the air permeability is improved by 30% or above, the horizontal liquid absorption height is increased by 10-15%, and the liquid absorption capacity can reach 3.0 g per gram of water; meanwhile, a wet strength promoter and a wet strength agent are added, so that the wet strength of the raw paper is enhanced; the prepared base paper has high water absorption and air permeability and good wet strength.

Description

technical field [0001] The invention relates to the technical field of paper towel processing, in particular to a preparation process of a high water-absorbing and breathable maternity paper towel base paper material. Background technique [0002] With the development and intensification of competition in China's paper product market, the market demand is constantly diversifying and specializing. Consumers' demand for paper towels has developed from basic requirements to deeper levels, among which the consumer groups associated with hospitals are one of the representatives of special consumer groups. This group of people has different specifications for toilet paper than ordinary paper towels, and their requirements for safety, health, and cleanliness of paper towels are much higher than ordinary paper towels. For example, after giving birth, mothers need large-scale, absorbent, breathable, high-wet strength, and highly hygienic medical toilet paper due to heavy bleeding. M...
