Abstract
The invention provides drying groove paper for a filter rod and a preparation method thereof. The preparation method comprises the steps that mechanical fiber removing is performed on a fluff pulp board to obtain fluff pulp; one or several of bast fiber, chemical synthetic fiber, cotton fiber, bamboo fiber and plant protein fiber is/are treated into fiber with the length of 2-10 mm; the treated fiber and the fluff pulp are evenly mixed according to the weight ratio of 1:9-1:1; air laying, glue spraying solidifying and drying forming are performed to obtain the groove paper. The groove paper prepared through the preparation method has the advantages of being high in bulk, good in filling property and high in filtering effect and can improve adsorption of tar, NH3 and NNK in cigarette smoke and improve the smoking comfort of cigarettes.
Description
Technical field
The present invention relates to cigarette filter rod material and preparing technical field thereof.
Background technology
Along with consumer is to the growing interest of health and safety problem, under the industry overall background of reducing tar and reducing harm, have and filter and regulate the cigarette filter of flue gas effect to become the focus of industry concern.And groove filter tip is owing to appropriateness can reduce tar content in cigarette, furrowfilter rod is used widely, and groove paper is as the critical material manufacturing furrowfilter rod, also day by day deep to the exploitation of its reducing tar and reducing harm potentiality.
Current industry generally believes, can be improved the reducing tar and reducing harm ability of furrowfilter rod by the channel away changing filter stick to a certain extent.A kind of string-type groove trapping filter tip disclosed in Chinese patent CN201774961U, a kind of trapping filter combiner for staggered grooves disclosed in Chinese patent CN201774963U, a kind of threaded groove intercepting filter tip disclosed in Chinese patent CN201774960U, multistage discontinuous groove filter tip rod disclosed in Chinese patent CN203120981U, a kind of V-arrangement line furrowfilter rod disclosed in Chinese patent CN203168019U, a kind of grid furrowfilter rod disclosed in Chinese patent CN203226266U.
Groove paper used is in the market all adopt traditional paper-making process preparation, pulls an oar, uses into paper machine and manufacture paper with pulp, through press dewatering, utilize drying cylinder to carry out drying to it and finally become paper by pure wood pulp fibre or with other fibers mixture.Disclosed in Chinese patent CN101158133A, cigarette furrowfilter rod body paper adopts bleaching needle-point leaf pulp to coordinate with viscose to manufacture, and paper has the advantages that air permeability is high, wrinkle is even, surface strength is high.For another example the application of a kind of corn husk disclosed in Chinese patent CN103726410A in mouth rod groove paper, adopt corn husk to make pone mulberry paper groove mouth rod through paper technology, overcome original mouth rod groove paper and burn and suck the shortcomings such as obvious paper taste and flue gas in process be dry at cigarette.
Groove paper has larger specific area, and it can contact filtration abundant with flue gas, therefore on groove paper, to improve its reducing tar and reducing harm function, can improve cigarette smoking quality by loading functional additive.The groove paper of CNT and the filter stick with this groove paper is had as Chinese patent CN203360934U discloses a kind of load, the one or both sides of paper scribble carbon nanotube coating, condensed-nuclei aromatics in adsorbable flue gas and heavy metal, and the free radical in flue gas can be reduced with imitating.Chinese patent CN201092646Y discloses a kind of cigarette filter rod groove paper with Pu'er tea adsorption layer, by binding agent, Pu'er tea adsorption layer is bonded in the one or both sides of groove paper, when not changing cigarette producing process, can effectively reduce the harmful substance of volatility and half volatile in main flume.For another example the harm reduction type acetate fiber furrowfilter rod of a kind of groove fiber element paper alkaline porous material disclosed in Chinese patent CN202407071U, Alkaline porous materials is coated on furrowfilter rod pure cellulose paper, the alternative burst size more than 20% reducing determination of hydrogen cyanide in mainstream cigarette smoke.
In sum, at present to the research of filter stick groove paper concentrate on the structural design of groove and groove paper load and on optimizing, to the manufacturing technique research of groove paper seldom, all fundamentally can not solve furrowfilter rod and groove paper Problems existing.Traditional groove paper easily subsides because the limitation of manufacturing technique exists groove and affects the problems such as outward appearance, large on cigarette odor-absorbing impact, flue gas is dry, causes the use of furrowfilter rod to be restricted.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide one can improve reducing tar and reducing harm ability, the familiar lacunas of conventional groove paper, not givey filter stick dry method groove paper and preparation method thereof can be improved again.
Object of the present invention is achieved through the following technical solutions:
A kind of filter stick dry method groove paper, the base material preparing high dry method groove paper is the mixture of Time of Fluff Slurry and other fiber; Other fibers described are the blended fiber of one or more in flax fibre, chemical synthetic fiber, cotton fiber, bamboo fibre, artificial beef plant, and other fibre length described is 2 ~ 10mm.
A preparation method for filter stick dry method groove paper, method is as follows:
(1) base material treatment: flossy pulp-board machinery is separated fine, obtains Time of Fluff Slurry; By the fiber that a kind of or required wherein several process in flax fibre, chemical synthetic fiber, cotton fiber, bamboo fibre, artificial beef plant are length 2 ~ 10mm; The fiber handled well is mixed with the ratio of Time of Fluff Slurry according to weight ratio 1:9 ~ 1:1;
(2) air lay: the mixed uniformly fiber obtain step (1) and Time of Fluff Slurry are delivered on forming web, become fiber web through Negative pressure, controlling fibroreticulate grammes per square metre is 60 ~ 100g/m
2;
(3) glue spraying consolidation: spray adhesive to fibroreticulate one or both sides, the fountain height of adhesive is the 5%-30% of fiber net quality; Described adhesive to be mass concentration be 10 ~ 40% acetate copolymer emulsion;
(4) dryness finalization: the fiber web after glue spraying consolidation is carried out heated-air drying, obtains groove paper.
The present invention compared with prior art, has following characteristics:
1, compare traditional paper technology, groove paper prepared by air-laid process has the advantages that bulk is high, filling capacity good, filter effect is strong.
2, compared with conventional groove paper, groove paper of the present invention, because structure is fluffy, bulk is high, makes obviously to promote the filter efficiency of cigarette smoke, effectively can adsorb tar, the NH in cigarette smoke
3and NNK.
3, groove of the present invention standby cigarette filter made of paper, obviously can reduce throat and do thorn sense, improve the comfortableness of smoking cigarette, and then promote the suction quality of cigarette after smoking cigarette.
