Avient Launches Additional reSound™ Bio-Based TPEs Formulated with Renewable, Plant-Derived Content Avient Introduces CESA™ Fiber Additives for Heat Preservation to Help Meet Fashion Design’s Functional Needs Avient Introduces CESA™ Fiber Additives for Heat Preservation to Help Meet Fashion Design’s Functional Needs.

FIBER-LINE®’s marriage of high-performance fibers and additional processing create unique products that extend the life of our customer’s end use product. • Our yarn have been processed in a variety of different ways utilizing: Knitting, weaving, braiding. Packages can be supplied on colored, embossed and/or slit tubes. They also add important characteristics, such as SWELLCOAT® water-blocking, water repellence, adhe- sion, color, and wear and UV-resistance to these and many other applications.

These advanced, customizable formulations are ISO 10993 compliant, compatible with gamma, autoclave, or EtO sterilization, and come in pre- colored or natural grades. In addition to these high-performance characteristics, this healthcare portfolio offers a reduced carbon footprint over the product life cycle because PK production emits up to 61 percent less carbon dioxide (CO2) than nylon.
