A kind of cotton pulp wood pulp paper and its production methodTechnical field
The present invention relates to paper for daily use production technical field, in particular to a kind of cotton pulp wood pulp paper and its production method.
Background technique
Paper for daily use (such as tissue, face tissue, toilet paper) type on the market is more, and quality is irregular.LifeWhen being used with paper directly and the paper for daily use that uses of skin contact, especially women and infants, then higher to the quality requirement of paper.It is existingIn technology, paper for daily use generally has wood pulp paper, bamboo paper, straw paper etc., and flexibility is general, and the chance water capacity is easy to damage, some are evenRough surface is easy " picking " after wiping, is unable to satisfy women and infants or the easy allergy sufferers of skin use.In order to improve the soft of paperToughness, there are also the paper for daily uses for using cotton pulp and chemical fibre to manufacture for principle in the prior art, however such paper is discarded inIts Chemical fiber component is difficult to degrade in environment, causes environmental pollution.Therefore, it is necessary to propose a kind of new paper for daily use, it is flexibleProperty be improved, surface is submissive, and women and infants is suitble to use, and is easy to degrade in the environment.
As it can be seen that the prior art could be improved and improve.
Summary of the invention
Place in view of above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of cotton pulp wood pulp paper and its productionsMethod, it is intended to solve the flexible general technical problem of paper for daily use in the prior art.
In order to achieve the above object, this invention takes following technical schemes:
A kind of cotton pulp wood pulp paper, including following raw material by weight:
70~95 parts of wood pulp；
5~30 parts of cotton pulp；
3~15 parts of creams.
Preferably, the cotton pulp wood pulp paper includes following raw material by weight:
70~95 parts of wood pulp；
10~25 parts of cotton pulp；
5~10 parts of creams.
Preferably, in the cotton pulp wood pulp paper, the wood pulp is wood pulp made of needlebush or leaf wood.
Preferably, in the cotton pulp wood pulp paper, the range of the degree of polymerization of the cotton pulp is 500~1000.
Preferably, in the cotton pulp wood pulp paper, the whiteness of the cotton pulp is 85% or more.
Preferably, in the cotton pulp wood pulp paper, the ingredient of the creams includes polydimethylsiloxanes alkanol, dodecaneBase benzene sulfonic acid TEA salt, propylene glycol, glycerine and pure water.
The present invention also provides a kind of working systems of cotton pulp wood pulp paper, comprising the following steps:
(1) cotton pulp, wood pulp and creams are weighed by the proportion of raw material.
(2) weighed wood pulp and cotton pulp are subjected to pulping.
(3) by after step (2) pulping wood pulp and cotton pulp be further beaten to obtaining slurries.
(4) slurries for obtaining step (3) carry out copy paper and obtain page.
(5) page obtained in step (4) is subjected to rewind slitting, and adds creams.
Further, in the working system of cotton pulp wood pulp paper, the step (2) is intermittent pulping, wherein beating degree: 16~18 ° of SR, weight in wet base: 12~15g, temperature: 32~40 DEG C, concentration: 5.0~5.5%.
Further, in the working system of cotton pulp wood pulp paper, the step (3) is continous way mashing, wherein beating degree: 24~36 ° of SR, weight in wet base: 3~6g, temperature: 32~40 DEG C, concentration: 4.0~4.5%.
The utility model has the advantages that the present invention provides cotton pulp wood pulp paper and its production methods, it is compared with prior art, provided by the inventionCotton pulp wood pulp paper is since raw material includes cotton pulp and wood pulp, and fiber contained by cotton pulp is purer and high resilience, so that producingPaper for daily use it is homogeneous, flexible folding improves absorbability, meet water and be hardly damaged, thus with outstanding flexibility andThe features such as longitudinal wet anti-tensile is strong.In addition, in cotton pulp wood pulp paper provided by the present invention, since material composition includes creams, so thatIt is more submissive to produce resulting paper surface, when use will not injure skin, avoid as in the prior art by addition talcumPowder achievees the purpose that paper surface is smooth.In conclusion comparing existing paper for daily use, cotton pulp wood pulp provided by the present inventionPaper is more flexible, surface is more compliant, is more suitable for the users such as women and infants, skin easy allergy sufferers use.
