preparation example Construction

[0021] The preparation method of the present invention includes the steps of diacetate fiber treatment, air-laid, negative pressure adsorption, plasticizing treatment and curing and shaping, specifically including:

[0022] For the treatment of diacetate fibers, the diacetate fibers are firstly opened, then crushed to a size of 3-5 mm, and then set aside;

[0023] In the air-forming process, the uniformly pulverized diacetate fibers are transported to the forming net box by air flow for net-forming treatment;

[0024] The negative pressure adsorption is to adsorb the diacetate fiber to the forming net by means of negative pressure suction and control its thickness at 0.15-0.30mm;

[0025] In the plasticizing treatment, spray 5 to 15 parts by mass of a plasticizer for cigarettes with a purity of more than 99% on the front of the diacetate fiber layer; turn the diacetate layer over the net by means of negative pressure suction, and spray 5 parts by weight on the reverse side. ~...

Embodiment 1

[0031] After the evenly opened diacetate fiber tow is crushed and screened to a length of 3-5 mm, it is added in 100 parts by mass, and then transported to the forming net cage by air flow at a speed of 0.5 kg / min, and sucked under the condition of negative wind pressure of 5000 Pa. The wind falls on the mesh curtain running at 10m / min, and the nozzles arranged by the spray rods spray triacetin with a purity of more than 99% and accounting for 5% of the dry weight of the fiber to the front of the fiber layer. Under the negative wind pressure of 5000Pa, the suction The wind turns the fiber layer over the net, and sprays glycerol triacetate with a purity of more than 99% and 5% of the dry weight of the fiber on the opposite side, solidifies and shapes, and the non-woven fabric filter material for cigarette filter rods produced has a weight of 40g / m 2 , thickness 0.30mm, rolled into a filter rod, compared with the control (acetate white rod), the tar reduction rate reached 30%, an...

Embodiment 2

[0033] After the evenly opened diacetate fiber tow is crushed and screened to a length of 3-5 mm, it is added in 100 parts by mass, and then transported to the forming cage by air flow at a speed of 1.0 kg / min, and sucked under the condition of 6000 Pa negative wind pressure. The wind falls on the mesh curtain running at 25m / min, and the nozzles arranged by the spray rods spray triethylene glycol diacetate with a purity of more than 99% and accounting for 10% of the dry weight of the fiber to the front of the fiber layer. Under the condition of 6000Pa negative wind pressure Next, suck the air to turn the fiber layer over the net, spray triethylene glycol diacetate with a purity of more than 99% and account for 10% of the dry weight of the fiber on the reverse side, solidify and shape, and the non-woven fabric filter material for cigarette filter rods made Weight 45g / m 2 , with a thickness of 0.2mm, rolled into a filter rod, and compared with the control (acetate white rod), th...

Abstract

The invention discloses a high tar reduction diacetate fiber non-woven fabric filter material for cigarettes and a preparation method for the filter material. The filter material comprises 70 to 90 parts of diacetate fibers serving as a base material and 10 to 30 parts of cigarette plasticizer of which the purity is over 99 percent; and by a non-weaving technology, the base material and the plasticizer are processed into the non-woven fabric filter material which has a three-dimensional mesh-shaped structure and is used for cigarette filter sticks. The method comprises the procedures of diacetate fiber treatment, airflow net formation, negative pressure adsorption, plasticizing treatment, solidifying and sizing, namely crushing the loose and uniform diacetate fibers to be 3 to 5 millimeters, conveying to a net forming box through airflow to form a net, controlling the thickness of the formed net to be 0.15 to 0.30 millimeter by negative pressure adsorption, performing plasticizing treatment on the positive and negative sides, solidifying and sizing, and thus obtaining the high tar reduction non-woven fabric filter material. The filter material is loose and porous, has a three-dimensional netlike structure, improves the smoking quality of the cigarettes, and has a remarkable tar reduction effect. The preparation method is simple, convenient and stable and reliable in work, reduces the production cost, and improves the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and further belongs to the technical field of cigarette filter material processing, in particular to a diacetate fiber non-woven filter material for cigarettes with high tar-reducing properties and a preparation method thereof. Background technique [0002] "Low tar" is the current focus of attention of the domestic tobacco industry, and it is also a focus of attention of many consumers. The vigorous development of low-tar cigarettes on the one hand meets the needs of consumers to pursue healthy consumption, and on the other hand, it is a concrete manifestation of the industry's common values ​​of "national interests first, consumer interests first". Low-tar cigarettes are becoming one of the mainstream trends in the future development of the domestic tobacco industry. As a filter system for cigarette smoke, cigarette filters are effective measures to reduce the tar content in cigarett...
