Industrialization production method for diacetate fiber non-woven fabric filter stick base material for cigarettes

Abstract

The invention discloses an industrialization production method for a diacetate fiber non-woven fabric filter stick base material for cigarettes. The production method is characterized in that a non-woven fabric mechanical net formation mode and a spunlaced process reinforcement technology are adopted for preparing the filter stick base material. According to the production method, under the circumstance of achieving stable production by adopting the process technology, the high performance of acetate fibers can be utilized at the highest efficiency; according to the provided complete set, theprocess technology route is mature, the process route is short in process, the production efficiency is high, and industrialization production for the diacetate fiber non-woven fabric filter stick base material can be achieved; according to the method, in the process of preparation of a non-woven fabric filter material, harmful substances cannot be introduced, a production workshop is clean in environment, the production cost is low, and the product meets the requirements of the theme of green and environmental protection.

Description

technical field [0001] The invention relates to a method for industrial production of a filter rod base material prepared by using diacetate fiber filaments for cigarettes, and belongs to the technical field of filter materials for cigarettes. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards and quality, while tobacco products are constantly changing, the general public has put forward higher requirements for low tar content and low harm of cigarettes. At present, my country's efforts in reducing tar and harm are mainly reflected in the following three aspects: reasonable addition of flakes to cigarette formula; addition of special additives to filter rods; parameter optimization design of cigarette accessories with three papers and one rod; development of new environmentally friendly cigarette filters; Mouth materials will be the focus of tobacco companies. In order to meet the tobacco industry's r...

Problems solved by technology

[0003] The Chinese patent with the publication number CN 101199365A discloses a special spunlaced fabric of cellulose acetate for reducing tar and its production method. In the tobacco industry, the special cellulose acetate spunlace for filter sticks is a continuous filament, while the fiber suitable for non-weaving technology is short fiber. It is the most basic raw material for non-woven materials, and the fiber cutting technology is not mentioned in the patent; in addition, the patent mentions that the proportion of mixed viscose fiber is as high as about 40%, which shows that the patent exists in the production of acetate fiber spunlace cloth Certain technical difficulties, the higher the blending ratio of viscose fiber, the more unfavorable the interception efficiency of harmful components in the smoke, and even affect the appearance and taste of cigarettes; thirdly, due to the low breaking strength of diacetate fiber, it is difficult When doing this, try to reduce the number of contact points on the fibers. The single-roller card hand beater used in this patent is in the shape of a shaft, which will inevitably seriously damage the acetate fiber; finally, the journal paper "Diacetate" associated with this patent The article "Development and Application of Fiber Spunlaced Nonwovens" added that there is no web-laying machine, so the parallel web-laying process is adopted. The parallel web-laying occupies a large area and has a tendency to deviate laterally. Slight serpentine movement relative to the longitudinal center line, which will eventually affect the uniformity of the spunlace fabric

Si Xiangping mentioned in the article "Preparation and Performance Research of Acetate Fiber Nonwoven Filter Material" that acetate fiber was initially formed into a web by a small digital carding machine, and then carded by a carding machine to form a web. The process was repetitive and cumbersome, and the production efficiency was low. And the surface density of the prepared spunlace nonwoven material is as high as 106g / m 2 , it is difficult to meet the processing adaptability of the material on the filter rod forming machine
