Abstract
The invention discloses body paper of wettable tissues. The body paper is prepared from the following raw materials: 240-250 parts by weight of long fiber wood pulp, 400-450 parts by weight of short fiber wood pulp, caustic soda, pulping enzyme and a softener. A production process of the body paper comprises the following steps: a, selecting and preparing the materials; b, crushing, namely separately crushing the long fiber wood pulp and the short fiber wood pulp; c, grinding, namely degritting the crushed long fiber wood pulp, sending the wood pulp to a mill grinder, and adding the caustic soda and the softener for pulping; and d, papermaking from pulp, namely mixing the crushed short fiber wood pulp with the ground long fiber wood pulp for papremaking, thereby obtaining the finished body paper. According to the invention, long and short fibers in the raw materials are mixed for pulping in a reasonable ratio, and the short fibers are separately ground, so that the advantages of existing mixed grinding is kept while the problem of dehydration caused by overhigh beating degree is solved, the thickness of paper is increased, loss of fibers is lowered, and the tissues manufactured from the body paper are high in strength and good in softness and can be taken as wet tissues after wetted.
Description
Technical field
The invention belongs to pulp technology for making paper, specifically, relate to a kind of wettable toilet paper body paper and production technology thereof.
Background technology
Suitable long and short fibre furnish is the prerequisite of soft toilet paper of making a copy for, and long fiber pulp can give toilet paper enough intensity, and short fibered pulp is then larger on the impact of feel especially pliability.Therefore, intensity of manufacturing paper with pulp out and pliability be high-grade toilet paper all preferably, and the proportioning of long and short fiber will match.The raw material of current domestic toilet paper: long fiber mainly contains import bleaching needle-point leaf pulp or domestic cotton pulp, staple fibre has import or domestic bleached hardwood pulp, also has import to mix blank sheet of paper limit, the deinked pulp of waste paper or domestic printing house.
Good beating process is the guarantee of producing soft toilet paper for the manufacturing paper with pulp of toilet paper, and owing to being using fiber slurry kind different in size as raw material, therefore strictly must control beating process.In general, long fiber pulp kind has to pass through making beating, could give the intensity that toilet paper is enough, its beating degree, for some especially with the producer that full waste paper is raw material, usually inadvisable with the technique increasing beating degree to make up or improve intensity, because along with the raising of beating degree, energy consumption increases on the one hand, wet end drainage rate declines on the other hand, copy prompt drop low, the steam consumption increases, simultaneously also unfavorable to paper strength.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of wettable toilet paper body paper of the present invention and production technology thereof, by suitable fibre furnish, strict technology controlling and process, correct beating process, then other auxiliary agent being aided with superior performance, can reach and reduce quantitatively, quality of manufacturing paper with pulp out softness, the sanitary tissue that intensity is good, reach the object that paper handkerchief is wettable.
The present invention seeks to realize like this: a kind of wettable toilet paper body paper, its key is to be made up of following raw material: the caustic soda of the long fiber wood pulp of 240 ~ 250 weight portions, the staple fibre wood pulp of 400 ~ 450 weight portions, 0.35 ~ 0.45 weight portion, the making beating enzyme of 0.4 ~ 0.5 parts by volume, the softener of 2.5 ~ 3 parts by volume.
A production technology for wettable toilet paper body paper, its key is to carry out according to the following steps:
A, selection are got the raw materials ready: the long fiber wood pulp, the staple fibre wood pulp of 400 ~ 450 weight portions, the caustic soda of 0.35 ~ 0.45 weight portion, the making beating enzyme of 0.4 ~ 0.5 parts by volume, the softener of 2.5 ~ 3 parts by volume that weigh 240 ~ 250 weight portions;
B, fragmentation: after first being diluted by making beating enzyme, be divided into two parts, two parts of making beating enzymes mix with long fiber wood pulp and staple fibre wood pulp respectively, drop into two hydrabrushers respectively;
C, defibrination: desanding after the fragmentation of long fiber wood pulp, then deliver to mill fiberizer, then drop into caustic soda and softener carries out defibrination, and wherein refining concentration is 4.5%, and beating degree is 21 ~ 22 ° of SR;
D, pulping are manufactured paper with pulp: mixed with the long fiber wood pulp of step c in machine chest by the staple fibre wood pulp after fragmentation, then enter the machine of manufacturing paper with pulp, make finished product body paper.
Preferably, in above-mentioned steps c, the flow of defibrination is 45m
3/ h, pitch control agent is 15mL/min.
Preferably, above-mentioned making beating enzyme and water dilute in the ratio of 1:7.
Preferably, above-mentioned long fiber wood pulp is bleaching needle-point leaf pulp.
Preferably, above-mentioned staple fibre wood pulp is that Eucalyptus wood pulp, yearning between lovers wood pulp or leaflet are firmly assorted.
Beneficial effect:
A kind of wettable toilet paper body paper of the present invention and production technology thereof, in body paper raw material, long and short fiber is with slurry according to quantity, through processes, short fiber separates defibrination, namely retains existing mixing defibrination advantage, solve again because of the too high dehydration problem of beating degree, can improve sheet thickness, reduce fiber loss, the paper handkerchief intensity of manufacture is high simultaneously, pliability is good, and can soak and use as wet tissue.
