Embodiment

[0011] A toilet paper prepared from Cizhu pulp, the preparation method of which is:

[0012] Using the Cizhu pulp prepared by the above implementation 1-5, the above-mentioned fiber pulp is beaten in a double-disc refiner, the beating concentration is 5%, the beating pressure is 0.2MPa, the beating current is 35A, and the obtained after beating The pulping quality standard is: beating degree 42 ° SR, beating wet weight is 7g. Papermaking is performed on the pulp after beating to obtain the primary color toilet paper. The papermaking includes papermaking the pulp obtained after beating above, and the papermaking is carried out in a single cylinder, single dryer and single felt toilet paper machine, and the primary color toilet paper of the present invention is obtained after papermaking. The primary color toilet paper has a basis weight of 13.5g / m2, a transverse liquid absorption height of 50mm / l00s, a tensile index of 8.6Nm / g, a softness of 106mN, and a brightness of 26%.

Abstract

The invention belongs to the technical field of pulping and papermaking and particularly relates to life paper made from bamboo. The whiteness degree of paper pulp is 25-40% ISO, the tensile index is larger than or equal to 8 Nm/g, the folding strength is 15-140 times, the fracture length is 6-8 km, the ash content is smaller than or equal to 1.2%, the tearing strength is 150-600 mN, and the beating degree is 16-22 degree SR. The produced life paper is not subjected to the bleaching process, the life paper made from bamboo reserves the natural color of the bamboo and has good performance parameter, conventional wood pulp can be replaced with the bamboo, the bamboo is superior to the conventional wood pulp, it is avoided in that chemicals used in the bleaching process remain in the life paper, the manufactured bamboo pulp product does not contain dioxin and can adsorb organic halide and other carcinogenic substances, 100% of natural color of bambusa emeiensis is kept, pollution of waste gas and waste liquor caused by bleaching to the environment is eradicated, and thus the method has the characteristic of ecological environmental protection.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to a bamboo household paper. Background technique [0002] The fiber morphology and chemical composition of bamboo show good pulping performance. Judging from the pulp strength of pulping performance level, bamboo is a good raw material for papermaking, second only to coniferous wood and close to hardwood. With the development of the paper industry, the use of bamboo instead of wood to reduce the pressure on the paper industry’s demand for wood raw materials and to meet the requirements of ecological environmental protection provides a broad development opportunity for bamboo pulp and paper. For a long time, bamboo has been used as the main material instead of non- The technology of making pulp from wood plant fibers has been attracting attention. [0003] Household paper refers to all kinds of hygienic wiping paper used to take care of personal home and...
