Indonesian yarn manufacturer utilises new PET recycling technology

 PT Kahatex, one of the largest manufacturers of woven and knitted circular fabrics in Indonesia, is using Oerlikon Barmag Huitong Engineering’s homogenization technology for the mechanical recycling of prefabricated polyester (PET) waste.

The Oerlikon Barmag Huitong project is the result of the cooperation between Oerlikon Barmag and Yangzhou Huitong Chemical Technology Co., Ltd., which has developed an advanced technology that can effectively process different types of PET waste. This innovative solution efficiently treats post-industrial waste such as popcorn, bottle flakes and films. By ensuring a consistent and homogeneous melt, the technology significantly increases viscosity, enabling the production of high-quality primary products made from recycled PET (rPET), such as melt, chips and fiber material for direct spinning.

The practice of reusing waste is booming within the textile industry. In May 2022, PT Kahatex, which manufactures high-end textiles for the Asian, American and European markets, took a step towards sustainability by implementing a system capable of recycling 25 tons of popcorn and bottle flakes per day. The process converts waste into high-quality chips suitable for the production of POY and DTY textiles.

Homogenization technology is still very attractive and has been adopted by Kahatex and Chinese fiber manufacturers. They use this technology to recycle bottle flakes and yarn waste into staple fibers and filaments through a direct spinning process. This approach has proven effective and is gaining popularity within the industry.

“We are currently receiving inquiries not only from Bangladesh, but also from China,” says Oerlikon Barmag Product Manager Michael M├Ąchtig.
