nadequate material humidity mainly leads to the following associated phenomena:
- poorer material flow
- frequent yarn breakage
- lower weft speed
- electrostatic charging
High production performance realised efficiently – a policy that applies to an increased extent to the textile industry, due to the current competitive situation. Consistent room air humidity is one of the most important prerequisites for rational production.
The textile industry mainly processes raw materials with hygroscopic properties. Materials thus react with particular sensitivity to humidity fluctuations, expanding where air humidity increases and contracting where humidity values fall. Only a few synthetic fibres represent an exception in this respect.
Electrostatic charging is a complex problem in the textile processing. Friction against rollers, eyelets, yarn guides and many other machine parts is unavoidable, and it leads to charging that impairs production where low relative humidity prevails, even where conventional fibres such as wool, jute, cotton and natural silk are involved.
