Abstract

The invention provides a composite solid type filter rod, belongs to the technical field of cigarette process, and particularly relates to a design and manufacturing method of a new material filter rod in a cigarette filter. The filter rod consists of one or a combination of more than one of medical grade PVC (polyvinyl chloride), medical grade PLA (poly lactic acid) and polycaprolactone serving as a raw material, and an auxiliary material glyceryl triacetate, wherein the weight ratio of the raw material to the auxiliary material is (1-9):1. According to the composite solid filter rod and the preparation method, the passing route of smoke in the filter can be effectively prolonged, and harmful ingredients in the smoke can be effectively filtered.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to a design and manufacturing method of a new material filter rod in a cigarette filter tip. Background technique [0002] Since filter cigarettes began to be widely used in various brands of cigarettes in the world, consumers' interest in products with less smoke has increased a lot. The smoke produced when cigarettes are burned contains hundreds of chemical components that are harmful to the human body, especially tar, Various carcinogens such as nitrosamines, shredded tobacco and cigarette paper are burned to produce smoke, and the smoke passes through the cigarette filter to intercept some harmful components, and finally forms the smoke smoked by consumers. [0003] Currently recognized filter sticks are mainly made of acetate fiber and acrylic fiber. By increasing the length of the filter tip and making multi-component filter sticks, various additives a...
