Manufacturing method of polylactic acid fiber bundle for functional cigarettes and filter stick of functional cigarettes

Abstract

The invention discloses a method for manufacturing functional polylactic acid fiber tow for cigarettes and a filter rod thereof, belonging to the field of cigarette filter materials. In the melting spinning process of polylactic acid, a functional modifier is added to the crimping link. The sex improver is made by emulsifying glucono-δ-lactone, aspartame, and chitin-chitosan emulsion in parts by weight (50-200): (1-5): (200-800), with functions The property improver is diluted with water to 0.5%~5.0% of the weight ratio, and then combined with the spinning oil to emulsify, wherein the functional modifier diluted with water accounts for 1.0%~15.0% of the weight ratio. (10-60) g / min, so that the weight ratio of the emulsion to the polylactic acid fiber tow for smoking is 0.5%-5.0%. The fiber tow is made into a filter rod and then smoked by cigarettes, which not only improves the smoking taste of cigarettes, but also eliminates miscellaneous smells, and has been recognized by the majority of smokers.

Description

technical field [0001] The invention relates to a method for manufacturing cigarette filter materials, in particular to a method for manufacturing functional polylactic acid fibers for cigarettes, and a filter rod made of polylactic acid fibers for cigarettes, belonging to the field of cigarette filter materials. Background technique [0002] At present, the raw materials of cigarette filter materials in my country are mainly cellulose diacetate and polypropylene. Among them, cellulose diacetate is made of cellulose esterified and dissolved in acetone. The process is complicated, the investment in equipment is large, and the source of raw materials is also limited. Larger restrictions; and polypropylene is derived from the polymerization of propylene from petroleum cracking. With the increasing shortage of petroleum resources, polypropylene is difficult to degrade in the natural environment. Therefore, the development of environmentally friendly new materials for cigarette ...

Problems solved by technology

[0004] At present, the development of the above-mentioned polylactic acid fiber tow and oil agent for cigarettes has not been industrialized, and has not been widely recognized in the cigarette filter material industry. One of the main reasons is that the smoking taste of cigarettes has not been significantly improved, and the It is difficult to be accepted by smokers for a while, so its application is greatly limited
