Technical characteristics of the product:

Dernier filament The weight expressed in length unit defined as the weight in grams of 9000mt of whatsoever linear material.
Dernier is a direct metric system where lower numbers are thinner dimensions and higher numbers are thicker dimensions. A single filament with a 9000mt length and with a weight of 1 gr is equal to dernier 1.
Total dernier. It is a weight in grams of acetate strip with a length of 9000 m. The acetate title is formed both by a dernier filament and total dernier. Example: an acetate title 2.7Y35000 has a dernier per filament (or filament dernier) of 2.7 and a total dernier of 35000.

Cross section The cross section Y is the one used on the tobacco industry.
Crimp The bending of a filament. Filaments are bent into groups and not singularly. Bending is necessary to give a certain consistency to a finished filter as well as to secure a good handling packing and storage.
