Process environment


The ambient conditions (temperature and relative humidity) play a very important role in the air jet spinning technology. A wrong condition has a huge impact on spinning stability and yarn quality. For spinning manmade fibres, the following conditions have to be secured in the spinning mill:

  • relative humidity: 48 - 56 %
  • temperature: 25 - 28 °C
  • replacement of air: minimum 25 - 28 times per hour optimum 28 - 32 times per hour.
