Embodiment 1

[0021] A method for preparing mixed single-denier tows for reduced-focus cigarette filter rods with an X-shaped cross-section. The vinegar sheet is dissolved in acetone to form a slurry, the slurry is filtered, and then enters the spinning equipment, and passes through the same spinneret. The spinneret holes of different apertures are spun to form three kinds of monofilaments with different linear densities. The spinnerets of the three different apertures are evenly distributed in the same spinneret according to the weight ratio; The thread densities are 2.3dtex, 2.7dtex, 3.0dtex, the ratio is 1:1:1, the cross-sectional shape of the monofilament is X-shaped, and the material of the monofilament is acetate fiber. A finished mixed monodenier fiber tow is produced. The breaking strength of the mixed single denier tow is ≥18.0N / Ktex, the water content is (6.0±1.6)%, the oil content is (0.70~1.50)%, the residual acetone content is ≤0.30%, and the titanium dioxide content is (0.40) ...

Abstract

The invention relates to the field of cigarette manufacturing, in particular to a mixed single denier tow for a scorch reducing cigarette filter rod with an X-shaped section and a manufacturing method and application of the mixed single denier tow. The mixed single denier tow is composed of three monofilaments with different monofilament linear densities, wherein the monofilaments are made by spinning after silk jetting is conducted through three spinneret holes with different bore diameters of the same spinneret plate. The three spinneret holes with different bore diameters are evenly formed in the same spinneret plate according to the weight ratio requirements. The monofilament linear density ranges from 1.0-3.5 dtex, the variable coefficient of the monofilament linear density ranges from 0.10-0.50, and the section of the monofilaments is in an X shape. The fracture intensity of the mixed single denier tow is equal to or larger than 18.0 N / Ktex, the moisture content is (6.0 + / -1.6)%, the oil agent content is (0.70-1.50)%, the residual acetone content is less than or equal to 0.30%, and the titanium dioxide content is (0.40 + / -0.20)%. The mixed single denier tow for the scorch reducing cigarette filter rod with the X-shaped section and the manufacturing method and application of the mixed single denier tow have the advantages of being much easier to process, high in effective work rate and more stable in scorch reducing efficiency.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, in particular to a mixed single-denier tow with an X-shaped cross section for a reduced-focus cigarette filter rod, a preparation method and application thereof. Background technique [0002] As consumers pay more and more attention to smoking and health issues, the tobacco industry has made some progress in tar reduction and harm reduction. The tar content of cigarettes has dropped from 17mg in 2002 to the current 11mg. By 2015, the State Tobacco Monopoly Administration requires that cigarettes The amount of tar on the box label shall not exceed 10mg, and the hazard index shall not exceed 9, which poses new challenges to the tobacco industry. At present, the low-tar cigarettes sold in the country are basically reduced by punching holes in cigarettes through special-shaped filter rods such as composite filter rods and paper filter rods. [0003] Chinese invention patent (application number...
