Bio-fiber for cigarette filter tips and preparation method of bio-fiber

Abstract

The invention discloses a bio-fiber for cigarette filter tips and a preparation method of the bio-fiber. The bio-fiber is prepared from, by weight, 8-10 parts of canna edulis starch, 20-22 parts of cassava starch and 5-7 parts of cigarette glue. The bio-fiber for the cigarette filter tips is prepared through the steps of material mixing, material stirring and forming, adopts renewable non-grain crops as raw materials and is environmentally friendly, low in carbon and degradable, the resources are renewable, and the fatal defects of cellulose acetate (CA) with wood pulp as a raw material are overcome; the bio-fiber has great prospects under the great background of environmental protection in China and in European and American countries where environmental protection is called for and has better effects of reducing harmful components and tar compared with cellulose acetate, it is detected that the nicotine content in smoke of one cigarette is smaller than or equal to 0.85 mg (the detection value is 0.82), the tar content of one cigarette is smaller than or equal to 10 mg (the detection value is 9.8), and the carbon monoxide content of one cigarette is smaller than or equal to 7.5 mg(the detection value is 7.5), tobacco coiling and packaging machine equipment does not need to be reconstructed, the industrialized production of cellulose acetate and propylene fibers (PP) is replaced without obstacles, and the price is lower.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a biological fiber for a cigarette filter, and also relates to a preparation method of the biological fiber for a cigarette filter. Background technique [0002] The cigarette filter is composed of a filter rod used to filter harmful substances in the smoke, and a coil paper and tipping paper used to wrap the filter rod. [0003] In the prior art, the fiber tow filter rod is mainly made of diacetate fiber tow or polypropylene fiber tow. Its filtering effect depends on their chemical molecular structure and the physicochemical properties of organic compounds. Among them, the disadvantage of the cellulose acetate tow filter rod is: the cellulose acetate tow filter material, due to the limitation of the lack of active groups, contains a part of the polar structure, which can only compare the polarity of the oxygen atoms contained in the smoke compound. Strong substances, such as ald...

Problems solved by technology

Among them, the disadvantage of the cellulose acetate tow filter rod is: the cellulose acetate tow filter material, due to the limitation of the lack of active groups, contains a part of the polar structure, which can only compare the polarity of the oxygen atoms contained in the smoke compound. Strong substances, such as aldehydes, ketones and lactones in carboxyl compounds, and heterocyclic compounds such as furan and phenolic substances have a certain affinity and a certain selective filtering effect; while carbon free radicals in smoke products that are harmful to the human body, etc. Aromatic hydrocarbons and propylene weakly polar compounds and trace metal elements have low adsorption capacity, and the interception rate of tar, which is the most harmful among them, is about 35%; acetate fiber tow filter material has negative charges, and many Particles are also negatively charged, and there are about 2×109 negatively charged particles per milliliter of smoke. Due to the repulsion of the same charge, this filter mainly traps particulate matter in the smoke through mechanical blocking and diffusion deposition; Its raw material is wood, without fibrils, and its filtration performance is limited; the cellulose acetate tow filter material is easy to absorb tobacco moisture and spices and cause mildew and musty smell

At present, there is no literature report on the use of cassava starch for the preparation of biofibers
