Problems solved by technology

In the existing technical thinking, in order to reduce the filter rod pressure drop and filtration efficiency of slim cigarettes, the design of acetate fiber tow with "high single denier and low total denier" is generally adopted. The number of tows contained is relatively small, thus amplifying the quality fluctuation of the tow itself, which in turn results in poor pressure drop stability of fine filter rods

Embodiment 1

[0029] In the fine filter rod with good pressure drop stability provided in this embodiment, the acetate tow is a non-Y-shaped cross-sectional shape of the acetate tow, and the cross-sectional shape of the non-Y-shaped cross-sectional shape of the acetate tow is The shape is O type respectively;

[0030] The specifications of the tow in the filter rod are as follows: the single denier is 5.0den, the total denier is 20000den, the water content is (6.0±1.6)%, the oil content is (0.70~1.50)%, and the broken Strength ≥18. 0N / Ktex, residual acetone content ≤ 0. 30%, titanium dioxide content (0. 40±0. 20)%.

Embodiment 2

[0032] In the fine filter rod with good pressure drop stability provided in this embodiment, the acetate tow is a non-Y-shaped cross-sectional shape of the acetate tow, and the cross-sectional shape of the non-Y-shaped cross-sectional shape of the acetate tow is The shape is type I respectively;

[0033] The specifications of the tow in the filter rod are as follows: the single denier is 4.5den, the total denier is 25000den, the water content is (6.0±1.6)%, the oil content is (0.70~1.50)%, and the broken Strength ≥18. 0N / Ktex, residual acetone content ≤ 0. 30%, titanium dioxide content (0. 40±0. 20)%.

[0034] After the slim filter sticks prepared in Examples 1 and 2 were made into slim cigarettes according to the prior art, the pressure drop and filtration efficiency of the slim filter sticks were tested. The test results are briefly introduced as follows.

[0035] Detection of pressure drop on fine filter rods:

Abstract

The application belongs to the technical field of producing fine cigarette filter sticks and especially relates to a fine filter stick having good pressure reduction stability and application thereof. According to the fine filter stick having good pressure reduction stability, the adopted diacetate fiber has non-Y-shaped section, the specification requirement of filter stick tows is single denier 4.5den to 5.5den, total denier 15000den to 25000den. The non-Y-shaped section diacetate fiber adopted in the application can be produced by properly improving present diacetate fiber preparation devices so that the operation is simple and easy to realize; on the basis of the improvement, the fine filter stick having good pressure reduction stability has good application effect; reference is provided for the design development of fine filter sticks and for the further improvement on the production technology of the fine cigarette filter sticks quality control.

Description

technical field [0001] The application belongs to the technical field of slim cigarette filter rod production, and specifically relates to a slim filter rod with better pressure drop stability and a patent application for its application. Background technique [0002] In recent years, slim cigarettes have shown a good momentum of development, and domestic cigarette industry enterprises are constantly launching new specifications of slim cigarettes to meet the diverse smoking needs of smokers. [0003] Slim cigarettes are not simply thinning thick cigarettes in the physical sense. The main reason is that while shrinking the circumference of ordinary thick cigarettes, the suction resistance, hardness, burning cone and wrapping of slim cigarettes The ash and so on will change, so the research and development ideas of traditional circular cigarettes are no longer suitable for the development of slim cigarettes. [0004] Small and compact size is the inherent advantage of slim c...
