Man-Made Fibre Opening and Preparation
topic
Man-made staple fibre opening uses gentler opening machinery than cotton due to the absence of trash and the sensitivity of synthetic fibres to mechanical damage, employing slow-speed pin rollers, inclined openers, and chute feed systems without heavy beaters or grid bars, with electrostatic charge management through antistatic spin finish and controlled humidity being critical for polyester and acrylic fibre processing.
Role
Prepares synthetic and regenerated staple fibres for carding with minimal fibre damage and static charge accumulation that would otherwise cause fibre wrapping on card clothing and uneven web formation, with opening machine configuration and intensity adjusted to match the fibre crimp, finish, and length characteristics of each synthetic fibre type.
