Background technology
As society continues to develop, requirement of the people for daily necessities increasingly improves, especially paper handkerchief.Existing paper
Towel uses wet strength agent papermaking mostly in process of production, improves the tearing toughness and tensile strength of paper, but exist and be easy to make
The problem of at sewer blockage, the processing modes such as traditional garbage loading embeading and burning can aggravate environmental pollution.
Invention content
In view of this, this application provides pure wood pulp paper handkerchief of a kind of no added fluorescent whitening agent and preparation method thereof, institute
It is good to state paper handkerchief degradability, tearing toughness is good, tensile strength is good and flexibility is good.
In order to solve the above technical problems, technical solution provided by the invention is a kind of pure wood pulp of no added fluorescent whitening agent
The preparation method of paper handkerchief, includes the following steps：
1) slurrying：Paper pulp raw material is crushed, obtains 20~28 ° of SR of beating degree, the paper pulp of concentration of slurry 4.0%~5.0%,
In parts by weight, the paper pulp raw material includes：15~30 parts of softwood pulp, 50~70 parts of hardwood pulp；
2) starching：Using cloth paddle head box starching, wet strength agent added into paper pulp in the cloth paddle head box, divided
Powder, softening agent, paper pulp degrading enzyme and enzyme effect buffer substance obtain mixture；In mixture described in 10kg, containing described wet strong
Dosage is (250~300) g, is (5~10) kg containing the dispersion dosage, is (200~300) g containing soft dosage, contains the enzyme
Effect cushion quality is (0.1~1) kg, is 200~600IU containing the degradation enzyme activity unit；
3) dehydration and drying to 5.5%~7.5wt% of page moisture content；
4) it wrinkles and batches；
5) cutting packaging.
Preferably, the sizing process jet-wire ratio (0.90~0.95):1.
Preferably, the wet strength agent is polyacrylamide.
Preferably, the dispersant is polyethylene glycol oxide.
Preferably, in parts by weight, the softening agent includes：5~10 parts of glycerine, 1~3 part of hyaluronic acid, nonionic
0.1~1 part of surfactant.
Preferably, the paper pulp degrading enzyme is beta-glucosidase or hemicellulase.
Preferably, the enzyme effect buffer substance is ammonium citrate or ammonium tartrate.
Preferably, the softwood pulp is North America softwood pulp, and beating degree is 12-16 ° of SR.
Preferably, the hardwood pulp is Brazilian hardwood pulp, and beating degree is 14-17 ° of SR.
The present invention also provides a kind of pure wood pulp paper handkerchiefs of no added fluorescent whitening agent, are prepared by above-mentioned preparation method
It arrives.
Preferably, the paper handkerchief quantifies 10~12 grams/m2。
Preferably, the paper handkerchief softness value < 30mN.
Preferably, thickness < 0.8mm/12 layers
Compared with prior art, detailed description are as follows by the application：
In the pure wood pulp paper handkerchief preparation process of no added fluorescent whitening agent provided by the invention, pulping process：By paper pulp original
Material is broken to obtain paper pulp, and addition wet strength agent, dispersant, softening agent, paper pulp degrading enzyme and enzyme effect buffer in sizing process paper pulp
Substance obtains mixture, and paper pulp raw material includes：Softwood pulp, hardwood pulp, paper pulp raw material are pure wood pulp, meanwhile, screen two kinds
Wood pulp matches, and improves the degradability of paper handkerchief.The addition of paper pulp degrading enzyme so that paper handkerchief is before use, since these enzymes are in
In drying regime, not show activity, when entering nature control environment after use, degrading enzyme is rapid by paper handkerchief with regard to acute activation
It decomposes, degradability is good；Meanwhile enzyme effect buffer substance provides the suitable microenvironment needed for enzyme reaction.
In addition, the present invention screens softwood pulp, hardwood pulp simultaneously controls its proportioning, is added in sizing process paper pulp a small amount of wet
Strong agent, dispersant, softening agent, improve the usage comfort of the pure wood pulp paper handkerchief of no added fluorescent whitening agent, ensure that nothing adds
Add that the pure wood pulp paper handkerchief tearing toughness of fluorescent whitening agent is good, tensile strength is good and flexibility is good.Meanwhile softening agent includes：Third
Triol, hyaluronic acid, nonionic surfactant, nonionic surfactant keep friction coefficient big due to hydrophobic group lipophile
Big to reduce, when human contact's fiber, fiber declines with human body frictional resistance, to obtain good feel, and due to it is non-from
Sub- surfactant can interfere the hydrogen bond association between being happened at paper fibre to soften page, to make paper become fluffy rich
It is full, obtain soft feel；Hyaluronic acid makes paper with good fine and smooth sense and with certain humidity, reduces rubbing for paper
Coefficient is wiped, to more soft, the suitable microenvironment after use needed for the enzyme reaction of enzyme effect buffer substance offer of the present invention
Conducive to the degradation of hyaluronic acid；The relatively low low volatilization of the very small surface tension of glycerol molecule structure, further functioning as makes paper obtain
The effect of soft feel is obtained, while glycerine is easily soluble in water, degradability is good.
Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, with reference to specific embodiment pair
The present invention is described in further detail.
