Embodiment 1

[0024] Use bamboo or moso bamboo that has grown for 12 to 18 months. After degreening and repeated rolling of gears, mechanical and physical methods such as cooking are used to degumming, and bamboo fiber is extracted from bamboo. The fiber is cleaned and carded. , Coarse, spun yarn and other processes are used to make 32s single yarn. The single yarn adopts the rotor spinning process, and is prepared into a core material with a diameter of 0.5mm after combining 4 strands under the condition of a twist of 400 twists / m.

Embodiment 2

[0026] Using the soybean dregs that have been squeezed out of oil as raw materials, the bean dregs are soaked in water, separated, and the protein is purified. The protein is grafted with hydroxyl and cyano polymers, and the fibers are formed by wet spinning. Yarn conditions, after cotton cleaning, carding, drawing, spun yarn and other processes to make 40s single yarn, the single yarn adopts rotor spinning process, and is prepared into 2mm in diameter after being combined into 10 strands under the twist condition of 300 twist / m Core.

Embodiment 3

[0028] Select 4 strands of 32s single yarn prepared in Example 1 and 5 strands of 40s single yarn prepared in Example 2, and use the rotor spinning process to ply under the twist condition of 300 twists / m to prepare a core material with a diameter of 2mm.

Abstract

The invention discloses a concentric filter core material and a method thereof. The method comprises the following steps that: fibers containing hydroxyl group or amino group undergo scutching, carding, drawing and spinning processes to be made into a single yarn, and the single yarn is made into piled yarn by using a rotor spinning process at a twist of between 300 and 500 twists per meter, and thus the required core material is obtained. After acetate fibers are released, the core material is drawn to a molding machine by adopting a drawing and positioning device, added to the center part of a filter by a filter molding device and processed to obtain a concentric filter bar. The concentric filter core material and the method thereof have the advantages of no requirement of adding molding paper, single molding, convenient use and low cost. As the concentric filter core material has stronger chemical absorption function to polarity compositions in smoke gas of cigarette, the travel path of aerosol particles is lengthened, the collision among the particles and the interception probability of the core material to the particles are increased, so that the aerosol particles are more easily deposited on the surface of the core material, thereby improving the filtering efficiency of the center position of the filter.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials and relates to a cigarette filter, in particular to a core material for a coaxial filter. At the same time, the invention also relates to a preparation method of the core material. Background technique [0002] As a filter system for cigarette smoke, cigarette filters play an important role in improving the quality and safety of cigarette smoking. As the contradiction between smoking and health problems becomes increasingly prominent, countries around the world pay more and more attention to the development of new filters and materials. The existing cigarette filters mainly include binary composite filters, ternary composite filters, hollow filters and coaxial filters. Core filter etc. [0003] Among them, the coaxial core filter refers to a filter formed by inserting a special filter core axially at the axial center of an ordinary filter. Compared with other composite filters, it h...
