Embodiment 1

[0022] A method for preparing mixed single-denier tows for reduced-focus cigarette filter rods with a Y-shaped cross-section. The vinegar sheet is dissolved in acetone to form a slurry, the slurry is filtered, and then enters the spinning equipment. 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 Y-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 ±0.20)%. Mixed single-denier tow is for...

Abstract

The invention relates to the field of cigarette manufacturing, in particular to a mixed single-denier tow with a Y-shaped section for a reduced-focus cigarette filter rod, a preparation method and application thereof. The mixed single denier tow is composed of three kinds of monofilaments with different linear densities obtained by spinning through three kinds of spinneret holes with different diameters in the same spinneret, and the three kinds of spinneret holes with different diameters According to the requirements of the weight ratio, it is evenly distributed on the same spinneret; the linear density range of the monofilament is 1.0~3.5dtex, the coefficient of variation of the linear density of the monofilament is 0.10~0.50, and the cross-sectional shape of the monofilament is Y-shaped; the mixed single denier The breaking strength of the 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±0.20)%. The invention has the characteristics of easier processing, high effective operation rate and more stable coking efficiency.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, in particular to a mixed single-denier tow with a Y-shaped 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: 20071...
