Embodiment 1

[0032] 1, the present invention adopts and adopts raw material proportioning:

[0033]Bagasse pulp and coniferous wood pulp are used as raw materials, ratio: 80-90% bagasse pulp + 10-20% coniferous wood pulp, bagasse pulp is cooked by kraft method and oxygen delignification, and kraft method is used for cooking and oxygen delignification Lignin, coniferous wood pulp When purchasing commercial pulp, the main consideration is that if whole sugarcane pulp is used for papermaking, although it has better water absorption, it has higher hardness and slightly weaker tensile force. After adding 10-20% coniferous wood pulp, it can improve paper quality. softness and toughness.

[0034] 2. Treatment of slurry:

[0035] 1) Use a hydraulic pulper to crush the pulping board;

[0036] 2) The high-concentration desander purifies the slurry and removes sand and other impurities;

[0037] 3) Use a double disc mill to loosen the slurry, reduce the degree of beating, and improve water absorpt...

Abstract

The invention relates to a method for papermaking, and particularly relates to a method and equipment for producing a paper hand towel form bagasse pulp as a main raw material. According to the method, firstly, 80%-90% of bagasse pulp and 10%-20% of softwood pulp are taken as raw materials, wherein the bagasse pulp is boiled by a sulfate process, washed and then bleached so as to obtain bleached bagasse pulp, and the softwood pulp adopts market pulp; secondly, an aquapulper, a high concentration grit separator and a double disc refiner are used; thirdly, a proper wet strength agent is adopted; fourthly, a crescent high speed toilet paper machine is adopted; fifthly, a low beating degree is adopted; sixthly, in the whole process from pulp preparation to paper rolling, automatic operation control with a DCS (distributed control system) is adopted, paper sheet quantification and moisture are monitored on line and regulated automatically by a QCS (quality control system); seventhly, a point-to-point embossing manner is adopted; eighthly, a high-speed rewinding and splitting machine is used. The produced paper hand towel has tensile strength and proper air permeability, and reaches high standards in strength, wet strength, water absorption, air permeability, flexibility and the like.

Description

technical field [0001] The invention relates to a papermaking method, in particular to a method and equipment for producing paper towels from sugarcane pulp. Background technique [0002] Paper towel is a kind of household paper. It is a new variety developed in China in recent years. It has gradually replaced electric dryers and is widely used because of its hygiene, convenience, low cost, and environmental protection. Favored by consumers, it can not only be used to dry the water and oil on hands, but also clean the home. Someone once conducted an experiment, using paper towels, hand towels, and a dryer to dry the hands after washing their hands, and then tested the bacterial residues on the hands. The results showed that the paper towels had the least bacterial residues. It is now widely used in large and medium cities, hotels, guesthouses, companies and families in China, and its appearance has filled a blank in my country's household paper. Along with the raising of p...
