preparation example Construction

[0033] A kind of preparation technology of water-soluble toilet paper, specifically comprises the steps:

[0034] (1) After mixing the mixed bleached wood pulp and sodium carboxymethyl cellulose, it is disintegrated and beaten to obtain a mixed slurry;

[0035] (2) Screening and purifying the mixed slurry obtained in step (1), followed by slow-speed papermaking and pressing to obtain paper sheets;

[0036] (3) Alkali treatment is carried out on the paper sheet obtained in step (2) with weakly alkaline sodium salt, followed by drying and rolling to obtain water-soluble toilet paper.

[0037] In order to further optimize the above-mentioned technical scheme, the mixed bleached wood pulp in step (1) is a mixture of bleached softwood pulp and bleached hardwood pulp according to the following mass ratio: bleached softwood pulp 10% to 30%, bleached hardwood pulp 70% %~90%.

[0038] In order to further optimize the above-mentioned technical scheme, the mass ratio of sodium carboxym...

Abstract

The invention discloses water-soluble toilet paper and a preparation process thereof, and belongs to the technical field of toilet paper preparation. The method comprises the following steps: washingmixed bleached wood pulp with water, mixing the washed mixed bleached wood pulp and defibered and dispersed sodium carboxymethyl cellulose, and defibering and pulping in a pulping machine to obtain mixed pulp; screening and purifying the mixed pulp, slowly manufacturing paper with pulp by a papermaking machine, and squeezing to obtain paper sheets; and carrying out alkali treatment on the paper sheets by adopting a weakly alkaline sodium salt, drying, and rolling to obtain the water-soluble toilet paper. According to the invention, the preparation of the quick dissociation toilet paper is realized, the process is simple, the cost is low, and the preparation method is suitable for market popularization and application.

Description

technical field [0001] The invention belongs to the technical field of toilet paper preparation, and in particular relates to a water-soluble toilet paper and a preparation process thereof. Background technique [0002] Currently commercially available toilet paper raw materials are all wood pulp, and in the existing toilet paper production process, it is necessary to use a reasonable mix of long fibers, medium long fibers, and short fibers according to the characteristics of fiber length, and at the same time add some wet strength agents , softener and other chemicals, so that the toilet paper product has a certain physical strength and softness when used, so as to meet the use requirements of toilet paper. However, due to the type of fiber and the use of wet strength agents, the currently commercially available toilet paper is not easy to dissociate in the water after use in the toilet, so that the toilet paper will block the sewer when thrown in the toilet. Therefore, in ...
