Title (EN) HIGH DPF CELLULOSE ACETATE TOW AND PROCESS FOR MAKING
(FR) ÉTOUPE D'ACÉTATE DE CELLULOSE À DPF ÉLEVÉ ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Disclosed are cellulose acetate cellulose acetate tow and processes for making cellulose acetate tow having at least 15 denier per filament, e.g., at least 20 denier per filament, or at least 25 denier per filament. The cellulose acetate tows may have total denier of more than 20,500.
(FR) L'invention concerne une étoupe d'acétate de cellulose et des procédés de fabrication d'étoupe d'acétate de cellulose ayant au moins 15 deniers par filament, par exemple, au moins 20 deniers par filament, ou au moins 25 deniers par filament. Les étoupes d'acétate de cellulose peuvent avoir un denier total supérieur à 20 500.
