Abstract
The invention provides a production process for producing super-soft face tissue without using softening agent. The production flow sequentially comprises pulp crushing, pulping, blending, sand removing, stock screening, spouting and net feeding, dehydrating and shaping, squeezing and cylinder feeding, drying, shrinking, peeling and reeling. The production process does not add the softening agent any more on the one hand, and adopts long and short fibers to pulp respectively during pulp crushing and pulping; when paper webs are peeled from a Yankee dryer, by using a scraper of 75 degrees, through controlling matching and pulping degree of the long and short fiber pulp, moisture on a paper web feeding cylinder and corrugated veins of the paper webs, the production process achieves the aim of producing the super-soft face tissue without adding the softening agent.
Description
Technical field
The present invention relates to a kind of method for producing ultra-flexible face tissue, belong to the paper for daily use production technical field.
Background technology
Known face tissue production method by technological process comprise the pulpboard size degradation successively, pull an oar, join slurry, desanding, screening the pulp, whitewashing online, dehydration are shaped, squeezing upper cylinder half, drying, wrinklingly peel off, batch.Disclosed Chinese patent CN101338533A disclosed a kind of toilet paper producer method and promptly relates to aforementioned each processing step as on January 7th, 2009.Along with the raising of people's living standard, people are also more and more higher to the requirement of face tissue, main performance both ways, the one, the wet strength of requirement face tissue is big as far as possible, paper easy fracture not in wiping like this, and it is residual not have paper scrap after the wiping; Be that the requirement paper is soft as much as possible on the other hand, comfort level can be better when wiping examination like this.In order to guarantee to obtain high as far as possible pliability under the situation of wet strength, known face tissue in process of production, its making beating or tankman's preface generally add pliability, bulk and the absorbability of softener to improve them.Using the favourable aspect of softener is can satisfy the consumer to bulk, pliability and absorbefacient requirement, and disadvantage is to have increased softener and the froth breaking chemicals expends, and cost increases; For the consumer of some sensitive, the face tissue that has added softener causes allergic reaction when using easily.
Summary of the invention
The purpose of this invention is to provide a kind of production method of not using the ultra-flexible face tissue of softener.
The technical solution adopted in the present invention is such: a kind of method for producing ultra-flexible face tissue in turn includes the following steps according to production procedure:
1), will grow fine pulpboard and short fiber pulpboard and carry out the pulpboard size degradation respectively;
2), respectively to the processing of pulling an oar of long fine slurries and short fiber slurries, its beating degree of the fine slurries of length after making beating is handled is 23～26 ° of SR, the weight percent content of long fiber in slurries is 5%, the beating degree of short fiber slurries is 18～20 ° of SR, and the weight percent content of staple fibre in slurries is 5%;
3), will to grow fine slurries and short fiber slurries be that the ratio of 33%～40%:60%～67% is joined slurry by weight percentage, long fiber and the staple fibre weight percent content in slurries is 4.0%;
4), slurries being carried out desanding handles;
5), slurries carried out screening the pulp handle, remove undecomposed bulk or large scale fiber in the slurries with sieve;
6), slurries be sprayed on the moulding screen cloth form the paper spoke, the proportion control of spouting velocity and moulding screen cloth speed is 0.945～0.965;
7), the paper spoke is carried out processed, the mass dryness fraction that makes the paper spoke is 7%;
8), the paper spoke carried out press dewatering and heated-air drying handle, the mass dryness fraction that makes the paper spoke is 95%;
9), adopt the scraper of 75 ° of tool point angles that the paper spoke of raising on the gram drying cylinder is carried out wrinkling peeling off;
10) the paper spoke after will peeling off carries out rolling or cuts to batch to handle making ultra-flexible face tissue.
The invention has the beneficial effects as follows: the present invention pulls an oar respectively by adopt the length fibre in size degradation and pulping process, when peeling off from raising the gram drying cylinder, paper web spends scrapers with 75, thereby proportioning and beating degree by the fine slurry of control length, the moisture and the wrinkling lines of paper web of control paper web upper cylinder half, reach the purpose of the gentle toilet paper of production excess of export under the situation of not adding softener, thus the expense that can fundamentally save softener.
The specific embodiment
Embodiment discloses a kind of method for producing ultra-flexible face tissue, its by technological process comprise the slurry size degradation successively, pull an oar, join slurry, desanding, screening the pulp, whitewashing online, dehydration are shaped, squeezing upper cylinder half, drying, wrinklingly peel off and batch step, below concrete steps of the present invention are described:
1, will grow fine pulpboard and short fiber pulpboard and carry out the pulpboard size degradation respectively, and add pitch control agent in long fiber pulpboard size degradation process, addition is the 0.8Kg/ ton, does not stick with paste net when making paper sheet formation, guarantees paper-forming evenness, and the long fiber pulpboard size degradation time is more than 10 minutes; The short fiber line pulpboard size degradation time is about 7 minutes;
2, respectively to the processing of pulling an oar of long fine slurries and short fiber slurries, long fine slurry is sent into the making beating of jordan refiner defibrination and is handled, its beating degree of the fine slurries of length after the making beating is 23～26 ° of SR, the weight percent content of long fiber in slurries is 5%, staple fibre its beating degree after fluffer is discongested making beating is 18～20 ° of SR, and the weight percent content of staple fibre in slurries is 5%;
3, will grow fine slurries and short fiber slurries is that the ratio of 33%～40%:60%～67% is joined slurry by weight percentage, and long fiber and the staple fibre weight percent content in slurries is 4.0%;
4, slurries being carried out desanding handles;
5, slurries are carried out screening the pulp and handle, remove undecomposed bulk or large scale fiber in the slurries with sieve, screening the pulp adopts pressurized screen to handle, and pressurized screen applies the pressure of 0.3Mpa, and the aperture of screen cloth is 0.15mm;
6, slurries are sprayed on formation paper spoke on the moulding screen cloth, the proportion control of spouting velocity and moulding screen cloth speed is 0.945～0.965;
7, the paper spoke is carried out processed, the mass dryness fraction that makes the paper spoke is 7%;
8, the paper spoke being carried out press dewatering and heated-air drying handles, paper spoke mass dryness fraction after the squeezing is advisable with 36～40%, surface temperature of drier is controlled at about 95～98 ℃, be beneficial to form uniform coating at dryer surface, for peeling off with wrinkling of paper web creates good conditions, the paper spoke mass dryness fraction after the dried is 95%;
9, page is at the scraper of raising the 75 ° of tool point angles of wrinkling employing on the gram drying cylinder, when wrinkling contraction, can obtain higher wrinkle frequency so that make page, the wrinkle number is during near 30/cm, the wrinkle distance approximates 5: 1 with the thickness ratio of page, page can expand rapidly on the z direction, page density is reduced, and bulk, percentage elongation and pliability improve thereupon;
10) the paper spoke after will peeling off carries out rolling or cuts to batch to handle making ultra-flexible face tissue.
