Abstract
A method for forming a filter rod may include providing a bale of crimped tow band having about 10 denier per filament or greater and about 20,000 total denier or less, the crimped tow band comprising a plurality of cellulose acetate filaments; and placing the crimped tow band in an apparatus so as to form a filter rod.
Claims15
A filter comprising:
- a tow comprising a plurality of cellulose acetate filaments, wherein the tow has about 10 denier per filament or greater and about 15,000 total denier or less;
- and
- an additive,
- the filter having an encapsulated pressure drop of about 3.5 to about 20 mm water/mm length of filter, wherein without the additive the filter has an encapsulated pressure drop of about 3 mm water/mm length of filter or less, and the filter having a circumference of about 26 mm or less.
1 more element
A smoking device comprising:
- a filter having a circumference of about 26 mm or less and comprising a tow comprising a plurality of cellulose acetate filaments and an effective amount of an additive to achieve an encapsulated pressure drop of about 3.5 to about 20 mm water/mm length of filter, wherein the tow has about 10 denier per filament or greater and about 15,000 total denier or less, wherein without the additive the filter rod has an encapsulated pressure drop of about 3 mm water/mm length of filter rod or less;
- and
- a housing capable of maintaining a smokeable substance in fluid contact with the filter.
