Method and equipment for producing paper towels from sugarcane pulp

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.
