Embodiment 1

[0024] Select polylactic acid fiber tobacco tow with a linear density of 4.2ktex and a linear density of 3.8dtex, and open it on the ZL21 filter rod forming unit. Modified starch glue with 15% weight of polylactic acid fiber tobacco tow, with a specification of 26g / m 2 1. High-permeable forming paper with a width of 26.5mm, rolled into a filter rod with a specification of 144mm×24.1mm, dried at 80°C for 60 minutes, and then balanced at 22°C and 60% humidity for 6 After more than 1 hour, sampling test shows that the hardness of the filter rod is 88%, and the suction resistance is 3300Pa. The appearance of the filter rod is good, the cutting surface is smooth, and the cigarette is connected to the machine smoothly.

Embodiment 2

[0026] Select the polylactic acid fiber tobacco tow with a linear density of 4.8ktex and a linear density of 4.4dtex, and open it on the ZL21 filter rod forming unit. Add polylactic acid fiber tow weight of 12% modified starch glue, the specification is 40g / m 2 , Ordinary molding paper with a width of 26.5mm, rolled into a filter rod with a specification of 100mm×24.1mm, dried at 90°C for 50 minutes, and then balanced for 6 hours at a temperature of 22°C and a humidity of 60%. According to the sampling test above, the hardness of the filter rod is 89%, the suction resistance is 2800Pa, the appearance of the filter rod is good, the cut surface is flat, the machine accepts the cigarette smoothly, and the cigarette taste is close to the acetate filter rod, which can meet the requirements of cigarette use.

Embodiment 3

[0028] Select the polylactic acid fiber tobacco tow with a linear density of 4.5ktex and a linear density of 3.8dtex, and open it on the ZL23 filter rod forming unit. Add polylactic acid fiber tow weight of 18% modified starch glue, the specification is 40g / m 2 , Ordinary molding paper with a width of 26.5mm, rolled into a filter rod with a specification of 100mm×24.0mm, dried at 90°C for 50 minutes, and then balanced for 6 hours at a temperature of 22°C and a humidity of 60%. According to the sampling test above, the hardness of the filter rod is 89%, the suction resistance is 2900Pa, the appearance of the filter rod is good, the cut surface is smooth, the machine accepts the cigarette smoothly, and the cigarette taste is close to the acetate filter rod, which can meet the requirements of cigarette use.

Abstract

The invention discloses a method for making a polylactic acid fiber filter stick. The method comprises the following steps of: (1) loosening: loosening a polylactic acid fiber cigarette tow by using a filter stick molding machine set, wherein the line density of the polylactic acid fiber cigarette tow is 3.5-5.0Ktex; (2) gluing: spraying a degradable adhesive onto the loosened polylactic acid fiber cigarette tow; (3) molding and cutting down; (4) drying the filter stick; and (5) balancing: putting the dried filter stick into a balance chamber to be balanced more than 6 hours so as to make the polylactic acid fiber filter stick. With the adoption of the method for making the polylactic acid fiber filter stick, the problem of industrial production of the polylactic acid fiber filter stick can be solved, the production can be carried out by only using an existing filter stick molding machine set in market, the smoking taste of the made filter stick is approximate to that of a vinegar fiber stick, and the requirements on use of the cigarette can be met.

Description

technical field [0001] The invention relates to a method for preparing a filter rod for cigarettes, in particular to a method for preparing a completely degradable polylactic acid fiber filter rod. Background technique [0002] Cigarette filters play an important role in reducing coke and harm and improving the quality of cigarettes, and are an indispensable part of the cigarette production process. There are mainly two kinds of cigarette filter materials on the market at present, one is cellulose acetate filter rod, the other is polypropylene fiber filter rod. Fiber acetate filter rods have excellent overall performance and are mainly used in middle and high-end cigarettes. However, cellulose acetate tow is made of perennial high-quality wood, which is produced by chemical reaction to produce cellulose diacetate sheets, which are then dissolved in acetone and produced by dry spinning. out, the whole production process is complicated, the investment is large, the price is e...
