Description
Technical field
The invention belongs to daily chemical product technical field, and in particular to the preferable toiler roll of a kind of flexibility and toughness and its
Production method.
Background technology
Roll paper is a kind of widely used daily life paper, and use is widely spread with the advantage such as its health, convenient, and
It is subject to many favors of consumer.With the increasingly increase of roll paper demand, the requirement to its quality and performance is also higher and higher.
In addition to requiring roll paper and there is preferable antibacterial and sanitation performance, the requirement of higher is it is also proposed to its softness and toughness.
Roll paper species currently on the market is more, but due between each producer manufacturing process difference, cause to be produced
Roll paper product quality it is uneven, especially the flexibility of roll paper and toughness are difficult to meet the needs of client at the same time.
Chinese patent CN103696318A discloses a kind of production method of the face tissue of soft fluffy, and this method is matched somebody with somebody with height
Weight ratio is 65-75：The cane syrup and wood pulp of 25-35 is main raw material(s), using five sand removing processs, and it is each by adjusting
Pulp density is different before and after equipment；It is aided with using flexible wire-dividing broom purification beating process；Page technique is penetrated using high speed hot wind, it is raw
Output soft fluffy, toughness are strong, cost is low and meet the face tissue of sanitary standard.This method is changed using existing paper technique processed
Into further improving the flexibility and toughness of obtained face tissue.But the improvement for technique in this method is needed to rely on and set
Standby improvement could be realized, limit the technological improvement of some small-sized Zhi Zhi enterprises.
The content of the invention
For this reason, the technical problems to be solved by the invention are to provide a kind of production method of toiler roll, it is existing to solve
There is the problem of toiler roll can not meet flexibility and toughness requirements in technology.
In order to solve the above technical problems, the production method of toiler roll of the present invention, includes the following steps：
(1) pulp modifying is handled：Obtained paper pulp in a conventional manner is taken, freezing processing is carried out under cryogenic conditions, then will
Paper pulp after freezing processing carries out ice-melt processing, and circulates the step of above-mentioned paper pulp freezing and paper pulp ice-melt are handled, and is modified
Paper pulp after processing, it is spare；
(2) desanding：Desanding processing is carried out to paper pulp using five sand removing processs；
(3) screening the pulp：Screening the pulp processing is carried out to obtained slurries, to weed out undecomposed fiber in slurries；
(4) whitewash：Slurries are sprayed on shaping screen cloth and form paper spoke；
(5) it is dehydrated：Spoke made from paper is carried out dehydrating；
(6) it is dry：Paper spoke is subjected to press dewatering and heated-air drying processing；
(7) peel off：Paper spoke is peeled off using the scraper of 75 ° of tool point angles；
(8) wind：Paper spoke after stripping is wound, obtains body paper；
(9) pack：By gained body paper through rewinding, cutting and packing processes, to obtain the final product.
In the step (1), the paper pulp freezing processing step controlled at -20~-25 DEG C, the paper pulp ice-melt
Processing step controlled at 4~10 DEG C.
In the step (1), the cycle-index of the paper pulp freezing and paper pulp ice-melt processing step is 3-5 times.
In the step (1), the temperature difference described in every rear one cycle between freezing processing step and ice-melt processing step
More than the temperature difference described in preceding one cycle between freezing processing step and ice-melt processing step.
In the step (1), the temperature of freezing processing is less than freezing processing step in previous circulation in every latter circulation
Temperature, the temperature that ice-melt is handled in every latter circulation are above the temperature that ice-melt is handled in previous circulation.
In the step (1), the step of adding mannitol is additionally included in paper pulp described in the forward direction of freezing processing step.
The additive amount of the mannitol is the 5-10wt% of the pulp quality.
The paper pulp is starched for sucrose and/or wood pulp.
In the step (2), the desanding step specifically includes：A, one of macropore gauze is set before pulp washing case, except coarse sand；
Sand removing machine is installed, except middle sand before defibrination B,；C, one of mesoporous gauze is set after defibrination；D, sand trap is set before stuff box is entered；E、
One of aperture gauze is set in the head box lower part of paper machine, except fine sand.
The invention also discloses the toiler roll produced by the method.
The production method of toiler roll of the present invention, relies on existing paper technology and equipment, only by conventional paper
Slurry freeze-processing repeatedly of ice-melt, the modification of paper pulp fiber property is realized, is further improved between paper pulp fiber
Ductile strength, while also improve the softness of paper pulp fiber.Modified paper pulp is only with existing paper Processes and apparatus processed
Roll paper performance can be achieved to be substantially improved, further improve the softness and toughness of toiler roll, at the same its intensity and
Water absorbing properties have also been lifted.
The production method of toiler roll of the present invention, by controlling the temperature of freezing step and ice-melt step in each circulation
Difference increase, further improves the softness and toughness of roll paper, while its intensity and water absorbing properties are also further lifted.
In addition, production method of the present invention, also further improves roll paper by adding mannitol to help modifying agent
Performance.
