Embodiment Construction

[0020] A dual-fiber hybrid filter was prepared by using soybean raw silk fiber and acetate fiber for tobacco. Firstly, straighten 5kg of soybean raw silk fibers in the length direction and stretch them evenly in the width direction to form a thin layer with a width of 25 cm. Humidify with a little atomization or place in a humidifying box with a relative humidity of 90% and a temperature of 40°C to make it dry. Wetting the surface reduces curling and discharge caused by static electricity. Leave it for 15 minutes to allow the surface moisture to evaporate naturally. Stretch the cellulose acetate bundle into a thin layer, so that the width of the thin layer is the same as the stretched width of the soybean fiber; overlap and mix the wetted soybean fiber layer and the acetate fiber layer together to form a bundle, and then carry out 5 times Mixed stretching makes the two fibers mix evenly to form a mixed fiber bundle. Stretch the mixed fiber bundle transversely to 40cm to form...

Abstract

The invention relates to a method for preparing a cigarette dual-fiber hybrid filter tip by utilizing soybean fibers, and the method comprises the following steps of: disentangling and stretching a soybean fiber bundle, eliminating surface static electricity and reducing curling and winding of the fibers; forming the surface wet soybean fibers and cellulose acetate fibers in a ratio of 4:1 into tows, and evenly mixing the two fibers; transversely stentering the evenly mixed tow, drawing till no obvious lamination, and evenly applying a plasticizer to the surface; fabricating a cigarette filter stick by means of a filter stick forming machine, and then cutting the filter stick into filter tips for wrapping cigarettes. Compared with the prior art, the filter tip prepared by the method provided by the invention is even in voids, and is good in effect of capturing granule-phase and gaseous-phase particles and larger in fiber absorption surface; the soybean fibers adopted in the invention belong to regenerable plant fibers and can be easily and biologically degraded under natural conditions. The soybean fiber-acetate fiber hybrid filter tip can be used for providing a new technical way for cigarette production while keeping the quality of cigarette smoking unchanged and reducing the harm of cigarette smoking.

Description

technical field [0001] The invention relates to a method for preparing a cigarette filter and belongs to the field of tobacco processing. Background technique [0002] Filter is an important part of modern cigarettes. It relies on the filter material to absorb and intercept tar, nicotine and gas phase harmful components in cigarette smoke to reduce the content of harmful components in cigarettes entering the smoker's mouth, thereby reducing the impact of smoking on the human body. the level of danger. Therefore, filter material is of great significance to reduce the harm of cigarettes. [0003] Filter filter technology has developed rapidly since it was invented in the 1930s, and filter materials have also experienced development from pleated paper, polypropylene fiber, and acetate fiber. In modern cigarette production, cellulose acetate is basically used as the filter material of the filter, mainly due to its good elasticity, non-toxicity, tasteless, good thermal stabilit...
