[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...
