Description
Technical field
The invention belongs to field of papermaking more particularly to the tissues and its production technology of a kind of sandwich style.
Background technique
Paper pulp is the base stock of papermaking and the main reason of papermaking consumptive material.Usually manufacture paper pulp raw material is with plant
It is main, four major class: stem fiber-like, bast fiber class, seed hair fiber class and lumber fibre class can be divided into according to its fiber feature, especially with
Lumber fibre class accounts for more, while lignocellulose quality is also best, and price is also most expensive；It is divided into wood pulp, straw pulp, bamboo by raw material variety
Slurry, cotton pulp, secondary stock etc.；It is divided into natural color pulp, partly bleach pulp, bleached pulp, refined stock etc. by working depth；These paper pulp were being worked overtime
The material and the energy that journey is consumed are not quite similar, while price also differs huge.
The paper for daily uses such as tissue, toilet paper account for very big ratio, and mentioning with living standard in paper industry
Height, demand of the people to paper for daily use are increasing, it is desirable that higher and higher.Tissue is mainly used for the places such as hotel, office building
It wipes and uses after washing one's hands, be a kind of expendable perishable consumer goods.The performance requirement of tissue are as follows: higher dry strength and
Wet strength, lesser dry and wet intensity difference, certain water imbibition, pliability and evenness etc..Although tissue is with higher dry strong
Degree and wet strength, but its water absorption is little, needs to consume more paper when absorbing a certain amount of water.
Common tissue, toilet paper are usually closed by several layers of letterweights on the market, and with 100% Original Pulp purification and
At tissue papery it is good, and microbiological indicator, physical index are superior to other raw materials, but such tissue need it is more
Tree resources, cause the waste of tree resources very serious.Also have in current paper technology and produces environmental protection using secondary stock
Type tissue.Be limited to the physical property of secondary stock, quality of finished paper will receive large effect, as stiffness or tensile strength without
Method reaches standard.Moreover, the utilization of secondary stock increases the content of microorganism, compared with the finished paper of Original Pulp manufacture also
There is microorganism to remain hidden danger.
Patent document CN107881829A discloses a kind of method of pulp from decoloured waste paper production tissue, carries out to waste paper broken
Solution, pulping again after filtering and impurity removing, use cellulase and hemicellulase to carry out size degradation, In to fiber again during pulping
Flocculant is added in filter process, using modified deinking agent in deinking step, improves regeneration tissue water absorbing properties, again
With certain stiff degree.
Patent document CN109667186A is added to the secondary stock of a part in the manufacturing process of tissue, has saved original
The usage amount of raw wood pulp, while the anti-of protonation chitosan is utilized by addition protonation chitosan in slurry in the fabrication process
Bacterium feature eliminates the excessively high hidden danger of secondary stock bring content of microorganisms, and wet to promote paper with AKD substitution PAE wet strength agent
Intensity.
But it is above-mentioned using secondary stock production tissue tensile strength it is lower, wipe hand using when easily fester, produce
The quality of product cannot be guaranteed.
Therefore, it is necessary to provide a kind of technology for making hand tissue of environmental protection, inhaled using the tissue of production technology production
Water is big, and not only dry strength and wet strength with higher, reduce the content of microorganisms in tissue, also with higher anti-
Zhang Qiangdu.
