Laser cutting of sustainable polyester nonwoven fabric

Material

bluefiber is a 100% mono-material acoustic nonwoven made of polyester – largely produced from recycled PET bottles. The materials are odourless, harmless to health, durable and fully recyclable. Thanks to their open-pore structure, they provide highly efficient sound absorption. Typical application areas include open-plan offices, educational institutions, public buildings as well as technical applications for noise reduction in industrial environments.

Test setup

The M-1600 laser cutting machine was used for the test. The material was cut using the honeycomb table concept, which enables particularly effective vacuum build-up beneath the material. The channelled extraction of cutting emissions keeps the underside of the material almost completely clean. This makes it ideally suited for cutting fibre fabrics. Recommended laser power: 450 watts.

Result

The cut edges are lint-free and fray-free, and free from burn residues – even for delicate contours. Contact-free laser cutting ensures consistently high quality without tool wear. Tool changes and downtime are eliminated. Result: very good to excellent suitability.
