However, the bleaching process of BCTMP is only to transform lignin rather than remove it. As we all know, lignin has relatively active chemical properties and is prone to various chemical reactions such as oxidation reactions t

Example Embodiment

[0038] The household paper provided by the present invention includes at least one single-layer paper, the at least one single-layer paper includes two or more fiber layers, at least one of these fiber layers is formed of bleached chemical pulp, and the other at least one layer It is formed from high-yield pulp or a mixed pulp of high-yield pulp and bleached chemical pulp.

[0039] These single-layer papers with two or more fiber layers can be obtained on a paper machine with a double-layer headbox or multiple (e.g., three or more) headboxes. In the process of forming paper from pulp, the main parts of the surface of these fiber layers are intertwined with each other to form a single-layer paper with an integral structure.

[0040] Bleached chemical pulp is a low-yield pulp, with a yield of about 40% to 60%. The raw materials used in bleaching chemical pulp can be wood fiber raw materials or non-wood fiber raw materials. The wood fiber raw materials include softwood raw materials ...

Abstract

A piece of life paper comprises at least one piece of one-layer paper which comprises at least two fiber layers. The fiber layers are made from pulp with different kinds, wherein at least one fiber layer is made from bleached chemicqal pulp, and at least another fiber layer is made from high-yield pulp or mixed pulp formed by the high-yield pulp and the bleached chemicqal pulp. The invention further provides a manufacture method of the life paper. By using the high-yield pulp to replace part of bleached chemicqal pulp, wood resources can be saved, and production cost of thin paper can be reduced. Besides, the thin paper manufactured with pulp with high-roughness fibers has the advantages of high bulkiness and water absorption performance.

Description

technical field [0001] The invention relates to household paper and a manufacturing method thereof. Background technique [0002] Household paper, such as toilet paper, napkin paper, toilet paper, kitchen wipe paper, etc., is a necessity in people's daily life. The vast majority of tissue paper currently on the market is made from bleached chemical pulp. [0003] Bleached chemical pulp is a pulp obtained by mixing chemical agents with plant fiber raw materials, dissolving and removing non-cellulose components such as lignin in the raw materials by cooking, and then bleaching the separated plant fibers. Bleached chemical pulp has the characteristics of long fiber, good softness, high bursting strength and stable whiteness. However, the pulp yield of bleached chemical pulp is low, generally 40% to 60%, and the low pulp yield results in higher production costs of bleached chemical pulp. In addition, in the production process of bleached chemical pulp, the extensive use of ch...
