Description
Technical field
The invention belongs to pipe tobacco technical fields, and in particular to a kind of spinneret of pipe tobacco uses the spinneret
Pipe tobacco of preparation and preparation method thereof.
Background technique
In cigarette, filter tip assumes responsibility for the function of reducing tar and reducing harm, and pipe tobacco is the material of main part of filter tip.
Currently, the filter-tip material of Commercialization application is mainly cellulose acetate tow and polyacrylic fibres on domestic and international market
Beam, wherein the dosage of cellulose acetate fibre has accounted for 90% or more, due to haveing excellent performance, is used primarily in medium-to-high grade cigarette,
However the complete import of the raw material of cellulose acetate tow, technical equipment rely primarily on foreign corporation, part domestic enterprise is with poly- third
Alkene tow substitutes cellulose acetate tow, however polypropylene tows filter effect is bad, is only used in low-grade cigarette.
Polylactic acid tow has the advantage that 1) polylactic acid absorption property is excellent for cigarette, and alternative cellulose acetate is used

Object, popularization and application can be relieved energy crisis, preserve the ecological environment, reduce greenhouse gas emission；3) simple production process environmental protection is led to
Melt spinning method preparation polylactic acid tow is crossed, cellulose acetate tow production process complexity is solved, invests big and a large amount of acetone
Solvent environmental issue.
The curling of prior art pipe tobacco is all to use machine crimp, and deficiency existing for machine crimp is that crimpness is difficult to
It keeps, crispation number and crimpness can be greatly reduced under some tension effect.Conventional cellulose acetate tow and polyacrylic fibres
The crispation number of beam standard is all in 22-28/25mm, and on Filter tip shaping machine, tow is wound into after shredding under tension
Mouth stick；By analyzing tow in filter tip, not only crispation number is declined, but also is crimped angle and obviously become larger, Yuan Xiangao
