Problems solved by technology

Fragrance thread filters have the advantages of low requirements on the properties of fragrance substances, novel and beautiful appearance, etc., but there are also defects such as easy volatilization of fragrance substances, short fragrance storage time, uneven fragrance release, small adsorption amount of fragrance substances, and low transmission efficiency.
[0004] CN201410843396 discloses the method for using hydrochloric acid modified activated carbon to prepare sustained-release agent. The material used in this method is not safe enough at first. Hydrochloric acid is a strong acid and has volatility and toxicity. Activated carbon needs to be washed with pure water after modification with hydrochloric acid, which is not environmentally friendly. Industrial Wastewater Generation
Secondly, activated carbon itself has an uncomfortable taste, which is not suitable for pilot cigarettes, which is also the main reason why Chinese cigarettes use less activated carbon.

Abstract

The invention relates to a linear composite gel fragrance controlled-release filter stick and a preparation method and an application thereof. The preparation method comprises the following steps: preparing a mixture solution; preparing composite gel; adding perfume. A fragrant thread made of the conventional cotton thread or synthetic fiber does not need to be taken as a carrier, and a gel thread which is prepared by compounding polyethylene glycol and chitosan sodium carboxymethyl cellulose is used for simulating the conventional fragrant thread, so that the perfume adding amount of the fragrant thread filter stick can be effectively increased, and the perfume adding uniformity, controllability and stability are improved; through the composite gel, fragrant substances can be dispersed uniformly and be released effectively and volatilization can be reduced effectively, and meanwhile the novelty and interestingness of a cigarette filter stick are improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a thread-shaped composite gel fragrance slow-release filter stick, also relates to the preparation method of the thread-shaped composite gel fragrance slow-release filter stick, and also relates to the thread-shaped composite gel fragrance slow-release filter stick The use of filter rods. 【Background technique】 [0002] With the development of low-tar cigarettes, the increase of filling components in the leaf group and the application of ventilation technology have reduced the satisfaction and enjoyment brought by tobacco aroma to consumers. Directly participating in combustion not only wastes liquid raw materials, but also uncontrollable various substances generated by combustion, which does not meet the requirements of coke reduction and harm reduction. Because it does not directly participate in combustion and is convenient in ...
