Embodiment 1

[0022] A preparation method with a mixed single -dan beam with a mixed -scorched cigarette filter with X -shaped section is used to dissolve the vinegar tablets with acetone to form a slurry, filter the slurry, enter the spinning device, and go through the three types of the same spray plate.The three different cross -section shapes and single -wire density of the spray holes of different pores and single -wire density, three different holes of different pores are evenly distributed in the same spray plate according to the weight ratio;The density of the single wire wires is 2.3Dtex, 2.7Dtex, 3.0Dtex, the proportion is 1: 1: 1, the single -silk section shape is X, Y, and O -type.Beams, dry, swing, and packaging finally produce a mixed single -dan fiber beam finished product.The fracture strength of the mixed Shan Dan beam is ≥18.0N / Ktex, the water content is (6.0 ± 1.6)%, the oil content is (0.70 ~ 1.50)%, the content of residual acetone is ≤0.30%, and the titanium dioxide content...

Abstract

The invention relates to a mixed single denier strand for a tar-reduced cigarette filter stick with an X-shaped cross section and a preparing method and application of the mixed single denier strand. The mixed single denier strand is composed of single fibers with different single fiber densities, wherein the single fibers are formed by at least three different specifications of spinneret orifices of the same spinneret plate in a spinning mode, the different specifications of spinneret orifices are different in aperture or section shape or aperture and section shape. The single fiber density ranges from 1.0 dtex to 3.5 dtex, the variable coefficients of the single fiber density range from 0.10 to 0.50, the cross sections of the single fibers are in at least two of an X shape, a Y shape and an O shape. The breaking strength of the mixed single denier strand is equal to or larger than 18.0 N / Ktex, the moisture content of the mixed single denier strand is (6.0+ / -1.6) percent, the tar content of the mixed single denier strand ranges from 0.70 percent to 1.50 percent, the remaining acetone content of the mixed single denier strand is smaller than or equal to 0.30 percent, and the titanium dioxide content of the titanium dioxide is (0.40+ / -0.20) percent. The mixed single denier strand has the advantages of being easier to process, high in effective working efficiency and more stable in tar reducing efficiency.

Description

Technical field [0001] The present invention involves the field of cigarette manufacturing, especially in a mixed Shan Dan silk beam and its preparation methods and applications with an X -shaped cutting cigarette filter rod. Background technique [0002] With the increasing attention of consumers to smoking and health issues, the tobacco industry has made some improvements in the reduction of coking reduction and reduction in focus. The amount of cigarette tarrawal oil has dropped from 17mg in 2002 to 11mg now. By 2015, the National Tobacco Monopoly requires cigarettes.The box standard scorching oil does not exceed 10mg, and the harmful index must not exceed 9, which has put forward new challenges to the tobacco industry.At present, the low -coordinated cigarettes sold in China are basically combined with cigarettes to reduce coke through composite filter rods and paper filter rods.
