Abstract
The invention relates to a manufacturing method of a crepe paper product. A method for producing a paper towel comprises the following steps of: selecting 70-80 % of bleached softwood pulp and 20-30 % of straw pulp as raw materials; pulping the pulp by using a pulper, after beating the pulp by using a disc mill and adding auxiliary materials of an expanding agent, a softening agent and a wet strength agent to the pulp, molding, dehydrating and squeezing the pulp by using a Harper fourdrinier system; creping a wet paper sheet in a creping cylinder when the dryness of the wet paper sheet is 30-45 %, wherein an angle between a creping knife and the tangential line of a cylinder surface is 20-30 degrees, the cutting edge angle of a scraping knife sticking to the cylinder surface is 60-85 degrees, and the speed ratio of the creping cylinder and a heating cylinder is 1.15-1.18:1; and then drying the wet paper sheet by using the heating cylinder; and winding, rewinding and slicing the paper sheet so as to obtain a finished product. The method for producing the paper towel, provided by the invention, has the advantages as follows: through fiber variety and proportion selection and through the adoption of a wet creping process, the paper towel are produced; and the produced the paper towel has the advantages of tensile strength and proper air permeability; and the strength, wet strength, hydrophobicity, air permeability, flexibility and the like of the paper towel all reach higher standards; therefore, high quality and low cost are achieved.
Description
Technical field
The present invention relates to the manufacture method of crepe paper, especially belong in Ha Bashi fourdrinier wire wire multi-cylinder paper machine production technology, by the method that Selects and Applies wet crepe explained hereafter tissue of fiber species and ratio.
Background technology
Tissue is disposable sanitary articles in the existing paper for daily use, also claims to smear toilet paper, and it has drum, also has collapsiblely, is used widely in generation toilets such as average family, hotel, hotel, office building, airports.Tissue is with not staying a mao dirt on the defensive position, and is soft comfortable, replaced gradually the electric dryer in the toilet, well received.Tissue has two large important indicators: 1. water imbibition: high-hydroscopicity is the guarantee that a piece of paper is wiped both hands; 2. wet strength: finished paper is flooded the saturated rear intensity that generally can lose most intensity remainders and is called wet strength, the wet strength of tissue is higher than toilet paper, the too high toilet that causes possibly of the wet strength of toilet paper stops up, and the high guarantee of tissue wet strength is with not staying a mao dirt on the defensive position.Use tissue that following benefit is arranged: use the towel of public product institute, because of the easy hiding germ of towel, easily the both hands of cleaning are infected with germ, the use tissue is clean hygiene then; Tissue uses temporarily and does not abandon, and can be used to closed tap or opens the door, and the hand of avoiding just having cleaned touches again the Public Goods surface and is infected with germs or virus.Therefore, tissue is a kind of cheap, broad-spectrum paper kind.
In the prior art, it is the fibrous raw material of tissue that tissue mainly adopts the primary slurries such as wood pulp, straw pulp, sugarcane slurry, cotton pulp, perhaps adopts the mixed slurries such as grass fiber such as softwood pulp, awns bar slurry, reed pulp, bagasse pulp as paper making raw material.Adopt primary slurry, its production cost is higher; And adopt mixed slurry, then the selection of its fiber species and ratio has direct impact to the tissue quality of producing.Fibre stuff is copied paper, machine creped and dry method by making beating, pulping, online and is made, and tissue mainly adopts dry method or semidry method creping to produce.Dry crepe refers to first paper web be carried out drying, in mass dryness fraction is under 90 ~ 93% the state, to scrape wrinkle and finished product through creping doctor from dryer surface; Wrinkling the referring to of semidry method carried out suitable drying to paper web first, in mass dryness fraction is under 65 ~ 75% the state, to scrape wrinkle through creping doctor from dryer surface, and then, drying is dried to 90 ~ 93% mass dryness fraction and finished product again.The problem that dry method or semidry method creping are produced the tissue existence is: 1, in Wrinkling, because scraper is to the fierceness collision of paper web, and paper web and dryer surface have been in the state that is easy to peel off, after so scraper is wrinkling, the paper wrinkle is thick and flat, cause the papery dirt-removing power to descend, softness does not very affect result of use; 2, destroy easily the adhesion of the thermosetting resin chemical bonds such as the interfibrous hydrogen bond of page, strong humectant, thereby cause the tissue paper strength lower, particularly since papery owing to the fluffy paper scrap that produces, mao dirt, cause occurring easily in use the problems such as sticking hand, fragmentation, result of use is poor.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of method that Selects and Applies wet crepe explained hereafter tissue by fiber species and ratio.
For achieving the above object, the present invention is achieved by the following technical solutions: a kind of method of producing tissue, select 70% ~ 80% bleaching needle-point leaf pulp and 20% ~ 30% straw pulp to make raw material, after pulper pulping, disc grinder making beating, adding auxiliary material swelling agent, softener and wet strength agent, after the moulding of Ha Bashi long mesh paper making machine system, dehydration, squeezing, it is wrinkling in creping cylinder when l Water Paper page or leaf mass dryness fraction is 30 ~ 45%, the angle of creping blade and cylinder face tangent line is 20 ~ 30 °, and scraper is 60 ~ 85 ° in the basil of pasting the cylinder face; The velocity ratio of creping cylinder and heated drying cylinder is 1.15 ~ 1.18:1, and is then dry through heated drying cylinder again, batch, behind the rewind slitting product.
The invention has the beneficial effects as follows: the present invention adopts and does raw material by the mixed slurry that the selection of fibrous raw material kind is carried out an amount of proportioning, reduces production costs when guaranteeing papery; By wet crepe explained hereafter tissue, because l Water Paper page or leaf intensity is lower, therefore, the wrinkle that forms after the creping doctor collision is with regard to uniformity, can not produce the bad phenomenon such as paper scrap, paper powder, moreover, for the wet crepe technological requirement, the speed ratio of creping cylinder and heated drying cylinder is remained between 1.15 ~ 1.18:1, can control stable, desirable wrinkle state; Have certain tensile strength and suitable air permeability so that produce tissue, its intensity, wet strength, hydrophobicity, gas permeability, pliability etc. all reach higher standard, and the tissue matter high price of producing is low.
