Problems solved by technology

[0005] Although the wet strength effect of this kind of resin is good, it is not easy to degrade after curing, and it is difficult to recycle broken paper. Repulping must be completed under the conditions of strong alkali and strong oxidant, and the speed of solution in natural environment is relatively low. at slower
In addition, polyamide-epichlorohydrin resin has a high content of organic chlorine, which is not conducive to environmental protection; moreover, its cost performance is not high

Embodiment 1

[0026] Embodiment 1 wet strength is high, is easy to degrade, and the preparation technology of environment-friendly novel paper towel

[0027] (1) 65 parts of leaf wood fibers, 35 parts of bamboo fibers are prepared into long-fiber wood pulp, 50 parts of hardwood fibers, 20 parts of straw fibers, and 30 parts of bagasse fibers are prepared into short-fiber wood pulp;

[0028] (2) In the long-fiber wood pulp pulper, add water to adjust the wood pulp concentration to be 6.0wt%, and after disintegrating for 10 minutes, after the obtained pulping material is disentangled by the fiber disintegrator, it is beaten by a beater, and The fibers are cut and divided into filaments to obtain tapped long-fiber wood pulp, the degree of beating is 35°SR, and the length of long fibers of the tapped long-fiber wood pulp is controlled at 1.5-2 mm;

[0029] (3) In the short-fiber wood pulp pulper, add water to adjust the wood pulp concentration to be 6.0wt%, and after 10 minutes of disintegratio...

[0032] Embodiment 2 The wet strength is high, easy to degrade, and the preparation process parameter adjustment of environmentally friendly new paper towels (1) 65 parts of leaf wood fibers and 35 parts of bamboo fibers are prepared into long-fiber wood pulp, 50 parts of hardwood fibers and 20 parts of rice straw fibers 30 parts of bagasse fibers are prepared into short-fiber wood pulp;

[0033](2) In the long-fiber wood pulp pulper, add water to adjust the wood pulp concentration to be 6.0wt%, and after disintegrating for 10 minutes, after the obtained pulping material is disentangled by the fiber disintegrator, it is beaten by a beater, and The fibers are cut and divided into filaments to obtain tapped long-fiber wood pulp, the beating degree of which is 35°SR, and the length of long fibers of the tapped long-fiber wood pulp is controlled at 2.5-3.0mm;

[0034] (3) In the short-fiber wood pulp pulper, add water to adjust the wood pulp concentration to be 6.0wt%, and after 10...

Embodiment 3

[0037] Example 3 Adjustment of preparation process parameters of new paper towels with high wet strength, easy degradation and environmental friendliness

[0038] The preparation method of Example 1 is adopted, wherein the composition ratio of the mixed pulp is adjusted as follows: the content of long-fiber wood pulp is 83.5wt%, the content of short-fiber wood pulp is 15.75wt%, and the content of wet strength agent is 0.75wt%. The agent is dialdehyde starch and chitosan, and its ratio is 1:2, wherein, the length of the long fiber is controlled at 2.5-3.0mm, and the length of the short fiber is controlled at 0.5-0.75mm.

Abstract

The invention discloses tissue and a manufacturing method and application. The tissue is high in wet strength, easy to degrade and environmentally friendly. The tissue is prepared from, by weight, 75-85% of long fiber, 14.5-24% of short fiber and 0.5-1% of wet strength agent, wherein the length of the long fiber is 1.5-3.5 mm, and the length of the short fiber is smaller than 1 mm. According to the tissue, by controlling the length range and ratio of the long fiber and the short fiber in paper pulp, a small amount of environment-friendly wet strength agent is added, and the tissue can obtain high wet humidity and is easy to degrade.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a paper towel and a method for preparing the paper towel. Background technique [0002] With the development of society and the improvement of people's living standards, the number and variety of various household papers have increased greatly worldwide, and various disposable household papers have emerged one after another, especially for women, children and the elderly. richer. More and more paper towels have entered people's daily life, and all kinds of boxed facial tissues, paper handkerchiefs, napkins, purse paper, etc. have greatly facilitated everyone's life. Tissue paper is a kind of household paper, which has higher requirements on the fineness, softness and hygiene of the paper than ordinary toilet paper. [0003] Ordinary paper towels on the market are not strong enough when exposed to water, and tend to rot into pulp, leaving pulp lumps and paper dust in the wiping ...
