Embodiment 1

[0064] Weigh 12g of polyvinyl alcohol, was dissolved in 400mL of deionized water at 80 deg.] C to give a polyvinyl alcohol solution.

[0065] 3g polylactic acid particles were weighed, dissolved in 30mL of dichloromethane, to obtain a polylactic acid solution.

[0066] The propylene glycol solution of polylactic acid were charged in a syringe, the syringe pump is placed on two, coaxial needle connected to the reactor, the flow rate of two syringe pumps were 5mL / h (flow rate propylene glycol), 6mL / h (poly the flow rate of lactic acid solution), was added dropwise a solution of polyvinyl alcohol, mechanically stirred 6h, stirring speed of 250r / min, the product was vacuum filtration, washed with deionized water, then collected, i.e., to obtain a polylactic acid-Run capsule. Particle size was measured capsules 3.3mm.

Embodiment 2

[0068] Weigh 12g of polyvinyl alcohol, was dissolved in 400mL of deionized water at 80 deg.] C to give a polyvinyl alcohol solution.

[0069] Weigh 3.6g of polylactic acid particles, was dissolved in 30mL of dichloromethane, to obtain a polylactic acid solution.

[0070] The solution of polylactic acid and deionized water were charged in a syringe, the syringe pump is placed on two, coaxial needle connected to the reactor, the flow rate of two syringe pumps were 5mL / h (water flow), 6mL / h (flow rate of polylactic acid solution), was added dropwise a solution of polyvinyl alcohol, mechanically stirred 6h, stirring speed of 250r / min, the product was vacuum filtration, washed with deionized water, then collected, i.e., to obtain a polylactic acid water capsule. Water was measured to 3.5mm capsule diameter (see image 3 -a).

Embodiment 3

[0072] Example 2 and compared, the main difference is that the wall material solution PLA solubility of 0.15g / mL; as follows:

[0073] Weigh 12g of polyvinyl alcohol, was dissolved in 400mL of deionized water at 80 deg.] C to give a polyvinyl alcohol solution.

[0074] Weigh 4.5g of polylactic acid particles, was dissolved in 30mL of dichloromethane, to obtain a polylactic acid solution.

[0075] The solution of polylactic acid and deionized water were charged in a syringe, the syringe pump is placed on two, coaxial needle connected to the reactor, the flow rate of two syringe pumps were 5mL / h (water flow), 6mL / h (flow rate of polylactic acid solution), was added dropwise a solution of polyvinyl alcohol, mechanically stirred 6h, stirring speed of 250r / min, the product was vacuum filtration, washed with deionized water, then collected, i.e., to obtain a polylactic acid water capsule. Water capsule package diameter is about 4mm (see image 3 -b),

Abstract

The invention relates to a moisturizing capsule, which belongs to the field of cigarette filter materials. The moisturizer capsule of the present invention comprises a wall material and a core material; the core material is a humectant solution; the wall material is polylactic acid. The present invention also provides the preparation method of the moisturizing capsule, using the humectant solution as the core material solution; the organic solvent dissolved with polylactic acid as the wall material solution; the core material solution through the electrospinning coaxial needle (this invention The invention can also be called the inner hole of the coaxial needle), and the wall material solution is added dropwise to the coagulation liquid through the gap between the inner and outer holes of the coaxial needle of electrospinning, and after stirring, the solid-liquid is separated, washed and dried. have to. In addition, the present invention also provides the application of the moisturizing capsule. Compared with the previous moisturizing capsules, the present invention has simple steps, avoids the use of waxy materials, and can realize the coating effect without multi-layer packaging.

Description

Technical field [0001] The present invention relates to the field of the tobacco industry, particularly cigarettes, to a coating of additional materials. Background technique [0002] The moisture content of the flue gas has an important impact on the sensory quality cigarettes, increase the moisture of cigarette smoke can increase the comfort of cigarettes, reduce dryness and irritation. Humectants means applied to the tobacco to enhance the moisturizing properties of tobacco products, increased flexibility, reduced loss of material pieces, application of humectants can help to improve the intrinsic quality of the smoking article during processing of tobacco products, as applied suitably-Run tobacco agent (wire) is more oily, may reduce the irritation, and taste so good, additional humectants fragrant also have some role in the reduction of volatile perfume fragrance is applied, so that the intrinsic quality of the smoking article remains relatively stable, and therefore, humect...
