Dear Sirs,
This page obviously was created by someone from a company called POWER- HEAT- SET GMBH in Germany.
The article indicates some typical technical press literature sources, but the clear ojective of the article is to direct the reader towards the "power heat set" type of their system.
The issue is that in autoclaves the yarns or filaments are wound on bobbins and fixation takes place in a packed status (intermittent process), whereas in the machines of SUPERBA or POWER HEAT SET the yarns are submitted to heat setting in a chamber as individual yarns (continuous process), not packed on bobbins. The treatment is supposed to provide softer results, although heat- setting processes normally do not provide much different results from each other.
The aim of the artickle is to manipulate the readers opinion, because:
First, it suggests autoclaving is an "old" system. Modern autoclaves are being built and installed continuously in the textile industry and represent a lower budget solution against the continuous (the "power- heat- set") way of relaxation. Autoclave manufacturers are true competitors to POWER HEAT SET GMBH.
Second, it tries to suggest their product as an unique individual system whereas in the Textile Industry "heat- setting" with steam is as old as the old irons.
Third, the article elegantly oversees the fact that there is a direct competitor named SUPERBA from France, which makes the same type of unpacked relaxation of the goods in a continuous process.
Conclusively, there is no "power heat- set system", and moreover, it is not clear what "power" means. As the temperatures applicable to heat- set yarns are defined by the fibre properties and not by the way how the steam is applied, a PP yarn will be fixed at 120°C in any heat- setting machine, regardless if in an intermittent or continuous machine.
The machine builders have chosen different chambers and methods to apply the steam, thats all. If "POWER HEAT SET GMBH" has called their machine as "power heat setting machine", fine, but this is good for a marketing forum but not in an encyclopedia.
