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...

[0024] 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 1.5dtex, 2.0dtex, 2.5dtex respectively, and 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)%.
