Problems solved by technology

But the existing lotus fiber used in the textile industry, its softening modification technology is mainly chemical treatment methods such as alkali pretreatment, liquid ammonia pretreatment, ethylenediamine and urea, water mixed solution pretreatment, etc., in the process of treatment due to strong The chemical substances involved in the smell will remain less than the chemical smell, and the little remaining chemical smell will also seriously affect the smoking taste of cigarettes
Therefore, even the softened lotus fiber cannot be applied to cigarettes, and can only be used as an industrial application

Embodiment 1

[0023] One embodiment, the one tobacco specific steps lotus fiber prepared as follows:

[0024] (1) Select Fresh lotus petiole remove dirt and impurities from the surface of the lotus petiole was cut into the slag material, the slag material ground to form a slurry extruded material, the raw material slurry is added a 1% cellulase solution, heated to 50 deg.] C the reaction was stirred 2h, lotus fiber pulp obtained; wherein the concentration of the cellulase solution is from 0.5 to 1%;

[0025] (2) the step of lotus fiber slurry (1) was immersed in a concentration of 20% NaOH aqueous solution, and uniformly mixed and stirred to obtain a mixed material;

[0026] (3) The mix was charged with the digester by heating with steam cooking, and at 120 deg.] C, a pressure of 1.5 hours under 1.0Mpa reserved, and then the solid phase was separated by filtration from the cooking pot through a mesh to prepare a crude fiber ;

[0027] (4) The volume fraction of 15 to 20% aqueous NMMO solution a...

Embodiment 2

[0033] Example two: the one cigarette smoke lotus fiber in particular preparative procedure as in Example 1 with the same fiber preparation step lotus, and the lotus fiber cigarette filter according to the weight ratio of cellulose acetate filter was prepared composite of 20%, the specific preparation process is as follows: the tobacco preparation process in accordance with the prior lotus fiber cellulose acetate tow sequentially bundled, crimped, lotus fiber tow made, then the plastic molding, and cutting into lotus fiber filter section, and acetate tow and wrapping the composite wrap segments, prepared to contain smoke filter rod moisturizing lotus fiber B.

Embodiment 3

[0034] Third Embodiment, the one tobacco specific steps lotus fiber prepared as follows:

[0035](1) Select Fresh lotus root remove dirt and impurities from the surface of the lotus root material was cut into the slag, the slag material ground to form a slurry extruded material, the raw material slurry is added 3% cellulase solution, heated to 60 deg.] C the reaction was stirred for 2h, to give lotus fiber slurry; wherein the concentration of the cellulase solution is from 0.5 to 1%

[0036] (2) the step of lotus fiber slurry (1) was immersed in an aqueous solution of NaOH in a concentration of 30%, and well mixed to obtain a mixed material;

[0037] (3) The mix was charged with the digester by heating with steam cooking, and at 120 deg.] C, a pressure of 1.5 hours under 1.0Mpa reserved, and then the solid phase was separated by filtration from the cooking pot through a mesh to prepare a crude fiber ;

[0038] (4) The volume fraction of 15 to 20% aqueous NMMO solution as a solvent...

Abstract

The invention provides a preparation method of lotus fiber for tobacco and a moisturizing filter rod containing the lotus fiber. The lotus fiber for tobacco is selected from fresh lotus petiole or lotus root after decontamination, crushed, extruded and ground to form a slurry-like raw material, added with cellulase solution, heated and stirred for reaction to obtain lotus fiber slurry, then added with NaOH aqueous solution and evenly loaded into a cooking tank with water Steam heating and cooking to separate the solid phase to obtain crude fibers, and then immerse in a mixed solvent prepared by NMMO solvent and acetic anhydride for esterification reaction to obtain esterified lotus fibers, and finally esterify lotus fibers with CO 2 The lotus fiber for tobacco is obtained by boiling, bleaching and softening with supercritical fluid. The lotus fiber for tobacco prepared by the invention has good softness and specific hygroscopicity, and can be applied to cigarette tip sticks, and its addition amount is 5-35% of the mass of the filter element, so as to provide relative moisturizing and moist feeling, soft and delicate smoke, and Increase the comfort and moist feeling of cigarettes; its smoke interception effect is better, and it is more conducive to reducing harmful substances and reducing cigarette tar.

Description

Technical field [0001] The present invention relates to the technical field of cigarette, in particular a method for preparing a cigarette filter having a function of moisture. Background technique [0002] Cigarette tobacco moisture content will not only affect the security of the physical properties of cigarettes and cigarette tobacco, cigarettes will also affect the sensory quality: dry weather conditions, tobacco and rapid water loss, low moisture mainstream smoke, irritating bias when suction large, significant dry feeling, easy to cause phlegm suction the oral cavity, thereby reducing the suction cigarette comfort; under wet conditions, the tobacco will absorb moisture from the surrounding air, causing smoke dull, easy to mold and cut tobacco. Therefore, the moisture content of tobacco products is an important technical aspects of tobacco control in the industry. [0003] Cigarette manufacturers a lot of research in cigarette-Run technology, mainly in three ways, First, add...
