In order to mechanically recycle prepared polyester (PET) waste, PT Kahatex, one of Indonesia’s major producers of woven and circular-knitted fabrics, has used homogenization technology from Oerlikon Barmag Huitong Engineering.
Barmag Oerlikon A partnership between Oerlikon Barmag and Yangzhou Huitong Chemical Engineering Technique Co. Ltd. called Huitong Engineering has produced cutting-edge technology that effectively manages various kinds of PET waste. This ground-breaking technique efficiently processes films, bottle flakes, and post-industrial trash (such as popcorn). This approach considerably increases viscosity by guaranteeing a consistent and uniform melt, enabling the creation of high-quality precursor goods made from recycled PET (rPET), including as melt, chips, and fibre materials for direct spinning.
Within the textile sector, the practise of waste recycling is gaining popularity. A system that can recycle 25 tonnes of popcorn and bottle flakes per day was put in place by PT Kahatex, which specialises in producing high-end textiles for the Asian, US, and European markets, in May 2022. The waste materials are converted through this process into premium chips that may be used to make POY and DTY fabrics.
The homogenization process is still quite alluring, and Kahatex and Chinese fibre producers have already accepted it. Through the use of direct-spinning techniques, they are using this technology to recycle bottle flakes and yarn waste into staple fibres and filament yarns. This strategy has been demonstrated to be successful and is rising in favour within the sector.
