In the field of spun-dyed filament yarns, Oerlikon Barmag, the market leader in filament spinning systems construction, now offers solutions for the efficient production of spun-dyed polyester POY and FDY microfibre yarns when using the EvoQuench radial quenching systems.

In the case of spin-dyeing polyester POY or FDY using the EvoQuench system, the particular focus lies on the long, stable duration of use for the sieves installed in the EvoQuench, the manufacturer reports.

This is said to ensure a highly- consistent yarn quality over long production periods and make a considerable contribution to reducing downtimes and consumption costs. 

Special design

With the exception of black, the dyes deployed in spin-dyeing are generally azoic dyes or organometallic complexes. These aromatic-based molecule systems can, in part, decompose at the high melt temperatures and evaporate directly underneath the spinneret.

While this evaporation does not result in lower durability and evenness when using a cross-flow quenching system, increased contamination of the sieves of the EvoQuench could well result in lowering their service life and the evenness of the yarn.

For this reason, the special design for spun-dyed yarn protects the sieves against contamination caused by evaporating dye particles, the company reports. Important design criteria include easy and fast cleaning during the routine pack wipe cycles. The trend towards spun-dyed yarns has numerous reasons. The most important benefits of spin-dyeing lie in the evenness of the dyeing results and in the ecologically considerably cleaner process.

Oerlikon Manmade Fibers segment

Oerlikon is a leading technology group supplying growth markets with market-leading technologies and services for surface solutions, systems for manufacturing manmade fibres, transmission systems and drive solutions, as well as prevacuum and high vacuum technologies and pumps and the corresponding accessories.

With its Oerlikon Barmag and Oerlikon Neumag brands, Oerlikon Manmade Fibers segment is the market leader for manmade fibre filament spinning systems, texturing machines, BCF systems, staple fibre systems and artificial turf systems and – as a service provider – offers engineering solutions for the entire textile value added chain.

With the expansion of the product range to include polycondensation systems and their key components, the company now caters to the entire process – from the monomer all the way through to the textured yarn. The primary Oerlikon Barmag markets are in Asia, and – for Oerlikon Neumag – in the USA, Turkey and China.
