Abstract

The invention provides a method for wet-making filter tip rod paper by using PLA fiber. The method comprises the following steps: (1) performing beating treatment on a fiber material containing polylactic acid; (2) diluting the above-mentioned mixed slurry, adding an auxiliary agent, then carry out forming treatment on a net, and then performing net section, pressing dehydration, and drying treatment to obtain dry paper sheets; and (3) coiling and cutting the dry page sheets in turn to obtain the filter tip rod paper. The filter tip rod paper is easy to process and form, has uniform indexes and good quality stability, and also has a good cooling effect. In addition, the fiber raw materials used in the method are all degradable, and green and environment-friendly, the glass transition temperature is low, and the cooling effect is good. The process is simple and practicable, the cost is low, production efficiency is high, and the filter tip rod paper with excellent properties and good smoking experience can be obtained.

Description

technical field

[0001] The invention belongs to the technical field of filter stick paper preparation, and in particular relates to a method for making filter stick paper by using PLA fibers in a wet process. Background technique

[0002] With the improvement of living standards, more and more people pay attention to the health problems of smoking. Heat-not-burn is currently a globally recognized healthy way of smoking. Heat-not-burn technology heats the cigarette just enough to deliver the flavor without igniting the cigarette. Normally, when ordinary cigarettes are ignited and smoked at a high temperature of 500-900°C, many harmful substances will be produced. However, heat-not-burn technology can control the temperature, greatly reducing harmful substances, and at the same time meeting the individual needs of young people. However, because shredded tobacco used in heat-not-burn cigarettes is different from ordinary cigarettes, it does not participate in combustion, the ...
