Problems solved by technology

[0003] Chinese patents CN102747454 and CN100569127 describe the preparation method of polylactic acid fiber tow and its application in cigarette filter materials. Although polylactic acid fiber has good biodegradability, when it is used in the preparation of cigarette filter rods, it must either be mixed with acetic acid fiber, or the polylactic acid plasticizer used affects the sensory quality of the cigarette, and the polylactic acid fiber does not show outstanding cigarette char reduction performance
The disadvantage of this method is that the process flow is long and the cost is high

Embodiment 1

[0023] Adopt the method of embodiment 1 to prepare the lyocell long filament of 3.33dtex linear density of monofilament, the tow of 50dtex of filament linear density is gathered in one stage, through friction disc type false twister and friction roller fibrillation treatment, beating degree is 20 The fibrillated tow of °SR is bundled in two stages to obtain a tow with a linear density of 3.8ktex. After crimping, the cigarette filter rod forming machine is used to produce a cigarette with a length of 100mm, a pressure drop of 2800Pa, and a circumference of 24.0mm filter stick.

Embodiment 2

[0025] Adopt the method of embodiment 1 to prepare the lyocell long filament of monofilament linear density 3.33dtex, the tow of 100dtex is 100dtex by one-stage clustering, through friction disc false twister and friction roller fibrillation treatment, beating degree is 25 The fibrillated tow of °SR is bundled in two stages to obtain a tow with a linear density of 3.8ktex. After crimping, the cigarette filter rod forming machine is used to produce a cigarette with a length of 100mm, a pressure drop of 2800Pa, and a circumference of 24.0mm filter stick.

Embodiment 3

[0027] Adopt the method for embodiment 1 to prepare the lyocell long filament of 3.33dtex linear density of monofilament, the tow of 200dtex of linear density of one-stage clustering, through friction disc type false twister and friction roller fibrillation treatment, beating degree is 32 The fibrillated tow of °SR is bundled in two stages to obtain a tow with a linear density of 3.8ktex. After crimping, the cigarette filter rod forming machine is used to produce a cigarette with a length of 100mm, a pressure drop of 2800Pa, and a circumference of 24.0mm filter stick.

Abstract

The invention discloses a method for preparing cigarette filter rods by Lyocell bundles and belongs to the technical field of cigarette filter stick manufacturing. According to the method for preparing the cigarette filter rods by the Lyocell bundles, Lyocell filaments are subjected to primary bundling to be fibrillated and then subjected to secondary bundling and curved to form the Lyocell bundles for manufacturing the cigarette filter rods. The method has the advantages that the Lyocell filaments after being fibrillated is remarkably higher in cigarette tar reducing capability and can be further used for manufacturing the cigarette filter rods, and the method is simple in processing route, controllable in fibrillation degree, low in cost and easy to achieve industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter preparation, and relates to a method for preparing cigarette filter rods from lyocell tow. Background technique [0002] Smoking is harmful to health, and the use of cigarette filters can reduce the harm of cigarettes. Therefore, research on cigarette filter materials has always been the focus of tobacco industry research. Since the first filter cigarette was born in 1930, paper, cotton, acetate fiber, polypropylene fiber, etc. have been used as filter materials in cigarettes, and acetate fiber is currently the most widely used. With the stricter laws and regulations in recent years, the tar requirement of domestic cigarettes has been gradually reduced from 17mg / cigarette to 10mg / cigarette and below, and the filtration performance of cellulose acetate has become increasingly difficult to meet the requirements of lower cigarette tar. Therefore, the research and development of new filter m...
