Embodiment 1

[0029] This embodiment provides a method for making filter stick paper using PLA fiber wet method, including the following steps: the selected fiber raw materials are: 20% bleached coniferous wood pulp, 75% PLA fiber (1.5dt*6mm), 5% PVA fiber %(1.1dt*3mm).

[0030] Rotary paper machine papermaking: speed 50m / min, beating process: bleached softwood pulp, concentration 3.5%, power 100KW, time 50min, beating degree 20°SR; PLA fiber slurry, concentration 1.0%, power 90KW, defrosting time 30min ; Then, the bleached softwood pulp that has been beaten, the PLA fiber slurry that has been decompressed, and the PVA fiber are stirred evenly in the mixing pulp bin, and the mixed slurry is diluted to a concentration of 0.8%, and the auxiliary agent is added. The auxiliary agent is: polyoxygen The addition of ethylene PEO is 0.8% (absolutely dry pulp), the concentration is 0.05%; the defoamer is 3.0kg / ton of paper; the antifoaming agent is 5.0kg / ton of paper; then it is processed on the Int...

Embodiment 2

[0033] This embodiment provides a method for making filter stick paper using PLA fiber wet process, including the following steps: the selected fiber raw materials are: 20% unbleached softwood pulp, 75% PLA fiber (1.5dt*6mm), PVA fiber 5% (1.1dt*3mm).

[0034] Papermaking on inclined wire paper machine: speed 100m / min, beating process: unbleached softwood pulp, concentration 3.5%, power 100KW, time 30min, beating degree 40°SR; PLA fiber slurry, concentration 1.0%, power 90KW, deflaking time 30min; then the unbleached softwood pulp after beating, the PLA fiber slurry and PVA fiber that have been decompressed are stirred evenly in the mixing pulp chamber, and additives are added: polyethylene oxide PEO addition amount 0.8% (dry pulp amount) , concentration 0.05%, defoamer 3.0kg / ton of paper; antifoaming agent 5.0kg / ton of paper; then carry out online forming treatment, and then go through wire section, press dehydration and drying treatment, of which online concentration: 0.03%;...

Embodiment 3

[0037] This embodiment provides a method for making filter stick paper using PLA fiber wet method, including the following steps: the selected fiber raw materials are: hemp pulp 20%, PLA fiber 75% (1.5dt*6mm), PVA fiber 5% ( 1.1dt*3mm).

[0038] Papermaking on inclined wire paper machine: speed 100m / min, beating process: hemp pulp, concentration 3.0%, power 100KW, time 40min, beating degree 30°SR; PLA fiber slurry, concentration 1.0%, power 90KW, defrosting time 30min; then Stir the beaten hemp pulp, decomposed PLA fiber slurry and PVA fiber evenly in the mixing pulp bin, dilute the mixed pulp to a concentration of 0.8%, and add additives, the additives are: polyethylene oxide PEO addition amount 0.8% (absolute dry pulp), concentration 0.05%; strengthening agent: 1.0% (absolute dry pulp); defoamer 3.0kg / ton of paper; antifoaming agent 5.0kg / ton of paper; After wire section, press dehydration and drying treatment, the netting concentration: 0.02%; the moisture of the paper she...

Abstract

The invention provides a method for making filter stick paper by using PLA fiber wet method, which includes the following steps: (1) beating the fiber raw material containing polylactic acid; (2) diluting the above mixed slurry, adding additives , to carry out online forming treatment; after that, the dry paper sheet is obtained through the wire section, press dehydration and drying treatment; (3) The dry paper sheet is coiled and slit in sequence to obtain the obtained product. The filter tip stick paper of the invention is easy to process and form, has uniform indexes, good quality stability and good cooling effect. Moreover, the fiber raw materials used in the method of the present invention are all degradable, environmentally friendly, and have a low glass transition temperature and good cooling effect; and the process is simple and easy, with low cost and high production efficiency, and can obtain excellent performance and excellent suction experience. The best filter stick paper.

Description

technical field [0001] The invention belongs to the technical field of filter stick paper preparation, and in particular relates to a method for making filter stick paper by using PLA fibers in a wet process. Background technique [0002] With the improvement of living standards, more and more people pay attention to the health problems of smoking. Heat-not-burn is currently a globally recognized healthy way of smoking. Heat-not-burn technology heats the cigarette just enough to deliver the flavor without igniting the cigarette. Normally, when ordinary cigarettes are ignited and smoked at a high temperature of 500-900°C, many harmful substances will be produced. However, heat-not-burn technology can control the temperature, greatly reducing harmful substances, and at the same time meeting the individual needs of young people. However, because shredded tobacco used in heat-not-burn cigarettes is different from ordinary cigarettes, it does not participate in combustion, the ...
