BRILEN’s very high shrinkage polyester yarns are engineered for technical applications requiring a high level of controlled shrinkage when exposed to thermal processing. Thanks to their exceptional shrinkage properties, these yarns enable the creation of more compact structures and help enhance specific functional characteristics of the final product through controlled contraction.

This range is specifically developed for industrial filtration and filter manufacturing applications, where the thermal behaviour of the yarn plays a critical role in the performance and efficiency of the finished material. Available in a wide range of linear densities from 140 to 9,900 dtex, these products provide solutions tailored to different manufacturing processes and technical requirements.

As a fully integrated European polyester yarn manufacturer, BRILEN controls the entire production process, from PET polymer production to final yarn manufacturing. This vertical integration ensures consistent quality, excellent reproducibility, and a reliable supply for even the most demanding customers.
