Learning outcomes
|
Wet-laid systems. Bonding by polymer dispersions, foams, pastes and solutions. Felting process. Surface treatment. Polymer-laid systems: Spun-bond, melt-blown and electrostatic spinning. Calender bonding, through-air bonding, infra-red and ultra-sound bonding. Theory of heating fiber layers. Structures, properties and end-uses of texti-les.
Students acquire knowledge of the subject and will be able to understand the obalsti nonwovens and bonding technologies. In view of the znolostem will be able to take on the role of the evaluator or technologist quality on an industrial scale.
