The raw material sources of described viscose rayon can be cotton pulp, wood pulp or bamboo pulp.The shape of cross section of this viscose fiber filament is circular, ellipse, and Y shape, a kind of in star or the rice shape preferentially selects the bigger Y shape of specific area, and star or rice shape are improved the adsorption capacity of fiber.
The manufacture method of this cigarette filter tip made of viscose rayon may further comprise the steps:
A, with wood pulp, cotton pulp or bamboo pulp are the viscose fiber filament of 1.5～8.0dtex for the feedstock production monofilament linear density;
B, be that 2～20% Polymer Solution applies fiber surface through dipping tank or spraying box weight percent concentration with viscose fiber filament, its coated weight is 5～50% of a viscose weight, under 50～200 ℃ of conditions solvent is dried by the fire 50～80% then, boundling is that line density is the tow of 3.0～4.0ktex;
C, the viscose rayon tow of surface-coated is curled through crimping machine, to become crispation number be the viscose rayon tow of 10～30/25mm to drying and shaping under 80～150 ℃ of conditions;
D, with the shredding of viscose rayon tow, spray triacetyl glycerine or pure water, in cigarette filter stick forming machine, wrap up plug wrap, cut into full-length, be packaged to be the viscose rayon filter stick.
The manufacture method of above-mentioned cigarette filter tip made of viscose rayon is wherein: b goes on foot described Polymer Solution, its solute is a cellulose acetate, modified starch, carboxymethyl cellulose, hydroxypropyl cellulose, methylhydroxypropylcellulose, the polymer of methacrylic acid and salt thereof, polyvinyl sulfonic acid and salt thereof, polyvinyl alcohol, one or both in the Sodium Polyacrylate etc. or two or more component; Its solvent is an acetone, one or both of ethanol or pure water.
In the manufacture method of above-mentioned cigarette filter tip made of viscose rayon: the d step is sprayed triacetyl glycerine or pure water, and purpose makes bonding mutually takes place between the fiber, improves the filter stick consistency and elasticity.
Because the present invention has adopted technique scheme, has the following advantages:
This technology is by to curling behind the viscose rayon silk surface-coated polymeric coating layer, makes the viscose rayon tow have good bulkiness and makes filter stick have better elastic, improved the time of staying of flue gas in filter stick and the filter efficiency of filter stick; Introducing by viscose rayon silk surface polymeric coating layer makes when making cigarette filter rod by spraying not have the triacetyl glycerine or the water that influence to sucking taste, has solved the adhesion problem between the bunch fiber, has improved the consistency and elasticity of filter stick; By regulating macromolecule kind and coated weight, can change the surface characteristic and the absorption property of viscose rayon easily.Main production equipments and technological process that this method can adopt the present cellulose acetate tow that generally uses to prepare cigarette filter rod.
The nontoxic free from extraneous odour of this filter stick, strong to the filter capacity of tarry matters in smoke, reduce tar content in every cigarette very significantly.Prop up kind, resistance to suction and suck under the taste condition at identical cigarette, compare with the cellulose acetate filter stick that generally adopts at present, can continue to reduce tar content about 10～20% on its basis, it is remarkable to fall burnt effect.When keeping the original sucking quality of tobacco constant, can reduce the filter stick production cost by a relatively large margin, thoroughly solve the fine filter stick raw material of China's vinegar anxiety, all the situation of dependence on import.In addition, viscose rayon can biodegradation in natural environment, and non-environmental-pollution has the advantage of green ecological.Have good using value and application prospect.
