From workshop to the big stage of synthetic fibre processing
Over four decades, Retech has built extensive know-how in the design and construction of heating and drawing elements for processing synthetic filaments.
Heinz von Arx founded the company in 1974, with the vision to create added value for customers in the field of thermal and mechanical fibre treatment. He learned from scratch, and his persistent curiosity meant he was practically bursting with ideas and enthusiasm. Innovation followed inspiration: technology progressed and success and failure led to high quality standards.
Retech has set a solid mark in the synthetic yarn production industry as the expert for temperature regulation – and the founder’s spirit still goes on.
“My father didn’t accept a ‘no’ or ‘impossible’ as an answer. With unmatched persistency he pursued the best solution in drawing fibres to perfection. We carry on with his legacy and still accept all challenges to be met with a technical solution.”
Ralph von Arx, Managing Director, Retech AG
