Embodiment 1
[0019] Take a polylactic acid tow for cigarettes, the single fiber linear density is 3.9dtex, the total density is 4.7ktex, and the number of crimps is 21±3 pieces / 25mm. The tow is opened and sprayed on a YL11 type opening and gluing machine, and then coated with triacetin, which is equivalent to 8% of the net weight of the fiber. Wrap and cut the rods on a YL21 filter rod forming machine, use D-grade filter rod paper and latex adhesive, iron at 170°C, and place the cut filter rods at room temperature for 48 hours. The resulting filter rod has a length of 120 mm, a circumference of 24.1 mm, out-of-roundness of 0.2 mm, a suction resistance of 3200±300 Pa, a hardness of 89±3%, a porosity of 87±3%, an even incision, no retraction, and no pollution smell. Tear off the wrapping paper and pick the filter rod with your hands to observe the bonding between the fibers.
Embodiment 2
[0021] Take a polylactic acid tow for cigarettes, the single fiber linear density is 3.1dtex, the total density is 5.0ktex, and the number of crimps is 21±3 pieces / 25mm. The tow is opened and sprayed on a YL11 type opening and gluing machine, and coated with a commercially available quick-drying solvent of cellulose acetate, and the actual coating solvent is equivalent to 9.5% of the net weight of the fiber. Rods were formed and cut on a YL21 filter rod forming machine, using grade D filter rod paper and latex adhesive, ironed at 160°C, and the cut filter rods were placed at room temperature for 24 hours. The resulting filter rod has a length of 120mm, a circumference of 24.1mm, out-of-roundness of 0.2mm, suction resistance of 3600±300Pa, hardness of 89±3%, porosity of 86±3%, incision even, no retraction, and no pollution smell. Tear off the wrapping paper and pick the filter rod with your hands to observe the bonding between the fibers.
Embodiment 3
[0023] Take a polylactic acid tow for cigarettes, the single fiber linear density is 3.2dtex, the total density is 3.8ktex, and the number of crimps is 24±3 pieces / 25mm. The tow is loosened and sprayed on the YL11 type opening and gluing machine, and the ethanol solution of triacetin (triacetin to ethanol volume ratio 2:1) is used to spin and coat the tow. The actual coated triacetin Equivalent to 5% of the net fiber weight. Wrap and cut into rods on a YL21 filter rod forming machine, use grade D filter rod paper and latex adhesive, iron at 170°C, and place the cut filter rods under ventilation at 40°C for 24 hours. The resulting filter rod has a length of 120mm, a circumference of 24.1mm, out-of-roundness of 0.2mm, suction resistance of 2800±300Pa, hardness of 86±3%, and porosity of 89±3%. Tear off the wrapping paper and pick the filter rod with your hands to observe the bonding between the fibers.
