Recyclable polyester-based tricot fabric with elasticity

Karl Mayer

In Germany alone, 390,000 tons of textile waste is produced every year. Every German person produces 4.7 kg of textile waste, of which only 0.5 kg are recycled. The rest is incinerated or dumped.

A key reason contributing to the low recycling rate is the purity of the material. The new fabric developed by the textile machinery manufacturer Karl Mayer Textilmaschinenfabrik GmbH, Obertshausen/Germany, offers an ecological alternative. The textile is made from yarns of different polyester polymers: a semi-dull version for a soft look and a bicomponent fiber that offers moderate mechanical elasticity with a well-thought-out structure. The elements of the stretchable fiber also consist of different polymers and show different shrinkage behavior: when heated, a spiral crimp is formed. As the bulky deformation is not mechanically induced – unlike in textured yarns – it produces a more permanent elongation in comparison.
The 2 polyester yarns were processed into a dense fabric on a high-performance HKS 3-M tricot machine in gauge E 32. The fabric weighs 202 g/m². It stands out thanks to its dense, rich feel and a heavy drape. Clothing made from it is comfortable to wear, easy to wash, does not need to be ironed and can be recycled after removing accessories such as buttons and buckles.
