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] Embodiment 1, the specific preparation steps of the lotus fiber for tobacco are as follows:

[0024] (1) Select fresh lotus petiole to remove dirt and impurities on the surface, cut the lotus petiole into raw material slag, extrude and grind the raw material slag to form a slurry raw material, add 1% cellulase solution to the slurry raw material, and heat to Stirring and reacting at 50°C for 2 hours to obtain lotus fiber pulp; wherein the concentration of the cellulase solution is 0.5-1%;

[0025] (2) immerse the lotus fiber slurry in the step (1) in a NaOH aqueous solution with a concentration of 20%, and mix and stir evenly to obtain a mixture;

[0026] (3) Put the mixture into a cooking tank, heat it with steam and cook it, and keep it at 120°C and a pressure of 1.0Mpa for 1.5 hours, and then separate the solid phase from the cooking tank through a sieve to obtain crude fiber ;

[0027] (4) Adopt the NMMO aqueous solution that volume fraction is 15~20% to make solv...

Embodiment 2

[0033] Embodiment 2: The specific preparation steps of the lotus fiber for tobacco are the same as the lotus fiber for tobacco in Example 1, and the lotus fiber for tobacco is compounded with acetate fiber according to the ratio of 20% of the weight of the filter core to prepare a filter element. The specific preparation process is as follows: the lotus fibers for cigarettes are sequentially bundled and crimped according to the existing preparation process of cellulose acetate tows to make lotus fiber tows, which are then glued, shaped, and cut to form lotus fiber filter core segments, and Composite wrapping molding paper with cellulose acetate tow section, and prepare moisturizing filter rod B containing lotus fiber for tobacco.

Embodiment 3

[0034] Embodiment three, the specific preparation steps of the lotus fiber for tobacco are as follows:

[0035](1) Select fresh lotus root to remove dirt and impurities on the surface, cut the lotus root into raw material slag, extrude and grind the raw material slag to form a slurry raw material, add 3% cellulase solution to the slurry raw material, and heat to 60°C Stirring and reacting for 2 hours to obtain lotus fiber pulp; wherein the concentration of the cellulase solution is 0.5-1%

[0036] (2) immerse the lotus fiber slurry in the step (1) in a 30% NaOH aqueous solution, and mix and stir evenly to obtain a mixture;

[0037] (3) Put the mixture into a cooking tank, heat it with steam and cook it, and keep it at 120°C and a pressure of 1.0Mpa for 1.5 hours, and then separate the solid phase from the cooking tank through a sieve to obtain crude fiber ;

[0038] (4) Adopt the NMMO aqueous solution that volume fraction is 15~20% to make solvent, add the acetic anhydride o...

Abstract

The invention provides a preparation method of tobacco lotus fibers and a moisture preserving filter tip containing the same. According to the tobacco lotus fibers, fresh lotus petioles or lotus rootsare selected to be cleaned, pulverized, squeezed and ground into a paste raw material to prepare a lotus fiber syrup by heating and stirring after a cellulase solution is added, a NaOH aqueous solution is uniformly added to a cooking pot to be heated and steam using vapour to separate a solid phase to prepare coarse fibers, the coarse fibers are immersed in a mixed solvent prepared by an NMMO solvent and acetic anhydride, esterified lotus fibers are obtained after leaching esterification reaction is conducted, and finally the tobacco lotus fibers are obtained after CO2 supercritical fluid isadopted to conduct boiling, bleaching and softening. The prepared tobacco lotus fibers have good flexibility and moisturizing performance and can be applied to cigarette filter tips, the adding amountis 5-35% of the mass of a filter core, relative moisture preserving and smoothness are achieved, smoke is softened and refined to improve the comfort and smoothness of cigarettes, the smoke interception effect is better, which can well help to reduce harmful substances and cigarette tar.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a method for preparing a cigarette filter rod with moisturizing function. Background technique [0002] The moisture content of shredded tobacco will not only affect the physical properties of cigarette tobacco leaves and the safety of cigarettes, but also affect the sensory quality of cigarettes: in dry climate conditions, the moisture content of shredded tobacco will be lost quickly, the moisture content of mainstream smoke will be low, and the irritation will be low when smoking. Large and dry, it is easy to cause phlegm in the mouth of the smoker, thereby reducing the comfort of cigarette smoking; under humid conditions, the shredded tobacco will absorb moisture from the surrounding air, resulting in dull smoke, and the shredded tobacco is prone to mold. Therefore, the moisture content control of tobacco products has become an important technical link in the tobacco indust...
