One can break up moisture paper tissue material and production method thereof
Technical field
The present invention relates to one and can break up moisture paper tissue material and production method thereof.
Background technology
Along with the fast development of economic level, the pursuit of people to quality of life is increased day by day, and health nonwoven material develops to environmental protection aspect.In the last few years, due to the discriminating of nonwoven material bamboo pulp fiber and viscose and performance test production technology easy, product structure uniqueness is changeable, the application of wide model is obtained in hygienic material, along with popularization and the development of global Green Product, non-woven sanitary material is also faced with new round innovation, and the nonwoven material that degradable can break up arises at the historic moment.In addition, the researcher of CaliforniaBerkeley finds, the blockage of sewer of 96% is because the Wiping material etc. that can not break up causes.These receive pay close attention to widely with namely abandoning Wiping material post processing, and the processing modes such as traditional garbage loading embeading and burning can weighting ring environment pollution, is solved the direction becoming industry research by the process problem of namely abandoning material by drainage system.Although the broken up Wiping material having brought into use nonwovens process to produce abroad, product is unsatisfactory, can not truly reach the effect that can break up, and there will be long, the wet situation on the low side by force of jitter time in some cases.The dry-laying spunlace non-woven material of current extensive use can not meet the demands.
Summary of the invention
The object of the present invention is to provide and a kind of there is broken up moisture paper tissue material and the production method thereof that the frivolous and degradable of quality can break up characteristic.
Technical solution of the present invention is:
One can break up moisture paper tissue material, it is characterized in that: be raw material with viscose, wood pulp fibre and ES fiber, adopts wet-laying, hot blast, hot-rolling method to be prepared from.
Break up a production method for moisture paper tissue material, it is characterized in that: comprise the following steps:
(1) viscose is become with ES fiber treatment: the long 4 ~ 10mm of viscose, the long 4 ~ 10mm of ES fiber, take the fiber of ratio requirement, wood pulp fibre 55% ~ 75%, viscose 17 ~ 42%, ES fiber 3 ~ 8%; And load weighted wood pulp fibre is soaked 0.5 ~ 2h in water;
(2) soaked wood pulp fibre is put into mixer, stirring to pulp 1 ~ 5min, wood pulp fibre is dispersed in water uniformly; Inject charging basket by after the wood pulp fibre having broken slurry and the viscose handled well and ES fiber Homogeneous phase mixing, and stir by stirring rod, prevent fiber from precipitating;
(3) slurry after Homogeneous phase mixing is injected wet-laying equipment, after using stripper plate to shake up and down, get rid of moisture fast in time, fiber becomes net under the effect of hydraulic pressure on forming net, then sample is extruded further to anhydrate point after take off standing and drying from forming net;
(4) sample after standing and drying is placed in the baking oven of 120 ~ 160 DEG C, makes ES fibers melt; Taken out from baking oven by sample, use hot press to carry out hot rolling, temperature is set as 30 ~ 50 DEG C, and pressure is 5 ~ 10MPa, and the time is 1 ~ 10s; Material completes.
When stirring by stirring rod in step (2), be stir according to " W type ", prevent fiber from precipitating.
Described surface density of breaking up moisture paper tissue material is 50 ~ 60g/m
2.
The present invention, based on paper technology, utilizes the nonwoven techniques preparations such as wet-laying can break up the method for non-woven moisture paper tissue material.This moisture paper tissue material is except having general hygenic towelette characteristic, and also have that speed of production is high, output is large, fibre web is quantitatively consistent, and quality frivolous and degradable such as can to break up at the characteristic.
Raw material environmental protection and wide material sources, product can be separated disintegration and become small pieces under the shearing force effect of current, and smoothly by toilet, drainage pipeline and sewage transport system under the effect of current, product after using is convenient to process, not needing to abandon landfill or burning, reducing with namely abandoning the pollution of product to environment.
Below in conjunction with embodiment, the invention will be further described.
Detailed description of the invention
Break up a production method for moisture paper tissue material, it is characterized in that: comprise the following steps:
(1) viscose is become with ES fiber treatment: the long 4 ~ 10mm of viscose, the long 4 ~ 10mm of ES fiber, take the fiber that proportioning (mass percent) requires, wood pulp fibre 55% ~ 75%(example 55%, 65%, 75%), viscose 17 ~ 42%(example 17%, 30%, 42%), ES fiber 3 ~ 8%(example 3%, 6%, 8%); And load weighted wood pulp fibre is soaked 0.5 ~ 2h(example 0.5h, 1h, 2h in water);
(2) soaked wood pulp fibre is put into mixer, stirring to pulp 1 ~ 5min, wood pulp fibre is dispersed in water uniformly; Inject charging basket by after the wood pulp fibre having broken slurry and the viscose handled well and ES fiber Homogeneous phase mixing, and stir according to " W type " by stirring rod, prevent fiber from precipitating;
(3) slurry after Homogeneous phase mixing is injected wet-laying equipment, after using stripper plate to shake up and down, get rid of moisture fast in time, fiber becomes net under the effect of hydraulic pressure on forming net, then sample is extruded further to anhydrate point after take off standing and drying from forming net;
(4) sample after standing and drying is placed in the baking oven of 120 ~ 160 DEG C (examples 120 DEG C, 140 DEG C, 160 DEG C), makes ES fibers melt (i.e. hot blast method); Taken out from baking oven by sample, use hot press to carry out hot rolling, temperature is set as 30 ~ 50 DEG C (examples 30 DEG C, 40 DEG C, 50 DEG C), and pressure is 5 ~ 10MPa(example 5MPa, 8MPa, 10MPa), the time is 1 ~ 10s(example 1s, 5s, 10s); Material completes.
Described surface density of breaking up moisture paper tissue material is 50 ~ 60g/m
