Description of the Related Art Cigarettes are manufactured by cutting paper used as a cutting wrap portion, wrapping dry tobacco in the wrap portion to form a cylindrical shape, and bonding a seam of the wrap portion with an adhesive. In addition, in the case of a cigarette with a filter, the formation of the filter and the bonding between the filter and the wrap portion are also performed. Cigarettes are about 2000-1 per minute
It is manufactured using a high-speed machine capable of manufacturing 4000 pieces. The adhesive is applied by spraying from a nozzle to a wrap portion, or by applying the adhesive to a side surface of a disk (disc) and then transferring it to the wrap portion. In order to cope with the production by such a high-speed machine, an adhesive having a high solid content and a low viscosity is required so that it can be easily applied to the wrap portion and the drying time is short.

Such an emulsion type adhesive is suitable for high-speed production of cigarettes because the viscosity can be easily adjusted. However, cigarettes made with EVA emulsions have a different taste in taste than cigarettes made with CMC paste.

For example, ethylene and vinyl acetate are emulsion-copolymerized in an aqueous solution containing carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA) as protective colloids. CMC and PVA are adsorbed on ethylene-vinyl acetate copolymer resin (EVA) as a protective colloid.

If it is lower than 0 mPa · s, the adhesive may permeate the paper too quickly, and the adhesive strength may not be sufficiently exhibited. On the other hand, if the viscosity is higher than 900 mPa · s, the application amount of the adhesive at the nozzle or the like becomes unstable, and high-speed production is difficult.

Parts, more preferably 2 to 6 parts by weight. If the CMC content is less than 1 part by weight, the taste will not be close to that of the CMC paste. On the other hand, when the content of CMC is more than 10 parts by weight, polymerization stability and initial adhesiveness are poor. When the content of PVA is less than 1 part by weight, polymerization stability is poor. On the other hand, when the content of PVA is more than 10 parts by weight, the viscosity becomes high, and the taste becomes CM.

On the other hand, when the degree of etherification of CMC is higher than 1.5, the taste becomes less similar to that of the CMC paste. If the average degree of polymerization of CMC is lower than 50, the taste becomes C
It does not approximate to MC paste. On the other hand, when the degree of polymerization of CMC is higher than 1500, the polymerization stability is lowered and the viscosity is also increased, so that the taste is not close to that of the CMC paste.

It is preferably from 0 to 2500. If the degree of saponification of PVA is lower than 80 mol%, the taste becomes less similar to that of the CMC paste. If the degree of saponification of PVA is higher than 96 mol%, the protective colloid capacity is insufficient, polymerization stability is reduced, and the viscosity stability of the obtained emulsion at low temperature is also inferior. If the average degree of polymerization of PVA is lower than 200, the taste becomes less similar to that of the CMC paste. On the other hand, the average degree of polymerization of PVA is 2500
If it is higher, the viscosity is high and the workability is reduced, and the taste is C.
It does not approximate to MC paste.
