Aramid Fiber Endless Tape For Cigarette Rod Forming Unit Of Decoufle Machines Containing Rod Paper And Tobacco
Garniture tape is used for cigarette making machines on format garniture sector to convey cigarette paper with tobacco wrapped in.We offer aramid tapes and Linen tapes.
para-aramid fibers, such as Kevlar and Twaron, provide outstanding strength-to-weight properties
high Chord modulus
high tenacity
low creep
low elongation at break (~3.5%)
difficult to dye – usually solution-dyed
good resistance to abrasion
good resistance to organic solvents
nonconductive
very high melting point (>500 °C)
low flammability
good fabric integrity at elevated temperatures
sensitive to acids and salts
sensitive to ultraviolet radiation
prone to electrostatic charge build-up unless finished
Besides meta-aramids like Nomex, other variations belong to the aramid fiber range. These are mainly of the copolyamide type, best known under the brand name Technora, as developed by Teijin and introduced in 1976. The manufacturing process of Technora reacts PPD and 3,4'-diaminodiphenylether (3,4'-ODA) with terephthaloyl chloride (TCl). This relatively simple process uses only one amide solvent, and therefore spinning can be done directly after the polymer production.
