Example Embodiment

[0035] Example 1

[0036] 1mol of powdered chitosan (molecular weight is 10000, degree of deacetylation is 90%) solution water, prepared into a 30wt% aqueous solution; take 0.143mol of copper chloride, dissolved in water, prepared into a 20wt% concentration of aqueous solution; Under the conditions, the copper solution was added to the chitosan solution, and the stirring was continued for 30 minutes to obtain a uniform solution. After standing for 8 hours, the chitosan copper complex solution was obtained. Add 0.6% of the weight of the cellulose acetate to the cellulose acetate based on the chitosan complex.

Example Embodiment

[0037] Example 2

[0038] 1mol of powdered chitosan (molecular weight is 10000, deacetylation degree is 90%) solution water, prepared into 30wt% aqueous solution; 0.143mol of ferric chloride, dissolved in water, prepared into 20wt% concentration of aqueous solution; other operations Same as implementation 1.

Example Embodiment

[0039] Example 3

[0040] 1mol of powdered chitosan (molecular weight is 10,000, degree of deacetylation is 90%) solution water, prepared into a 30wt% aqueous solution; take 0.071mol of ferric chloride and 0.071mol of copper chloride, dissolve in water, and prepare 20wt% aqueous solution; add the mixed solution of iron and copper to the chitosan solution under stirring conditions, and continue to stir for 30 minutes to obtain a uniform solution; other operations are the same as in implementation 1.

Abstract

The invention relates to an application of chitose complex on the cigarette filter up and belongs to the field of cigarette filter up process technique, wherein the chitose complex is used as the cigarette acetate fiber surface modification and additive agent; the chitose in the chitose complex is in a mole ratio with the total metal ions as 5:1 to 12:1. The invention has simple process and good utility, can improve the filtering property of the acetate fiber cigarette filter up, and can effectively lower the poisonous components, in particular coke tar, hydrocyanic acid and volatile aldehude in the cigarette smoke through the application of the modification and addition agents of the chitose complex in the acetate fiber. Compared with the cigarette made by the common acetate fiber tow of the filter up rod, the coke tar is lowered by 15.8 %, aldehyde substance is lowered by 27.1 % and the hydrocyanic acid is lowered by 29.2 % in the cigarette made by the invention process.

Description

technical field [0001] The invention discloses a preparation method of chitosan complex modified diacetate fiber and its application in cigarettes, belonging to the technical field of cigarette filter preparation. Background technique [0002] The harmful substances produced by cigarette combustion mainly include tar, carbon monoxide, hydrocyanic acid, volatile aldehydes, ammonia, nitrosamines, benzo[α]pyrene and phenols. There are cancer-inducing substances in tar, which can change the genetic structure of cells, turning normal cells into cancer cells, or stimulating stimulated cells, leading to the formation of tumors. Hydrogen cyanide is highly toxic. CN - Into the body, it can quickly interact with Fe of cytochrome oxidase 3+ Combined, the cells lose their ability to use oxygen, causing "cell suffocation" or "intracellular suffocation", the physiological and biochemical functions of the cells are also stopped, the structure is damaged, and eventually cell death is cau...
