Freudenberg launches recycled polyester shirt interlinings

Freudenberg Performance Materials Apparel (Freudenberg) has announced the worldwide launch of the RCY 99xx series, a range of recycled polyester (rPET) shirt interlinings. This new product line replaces the long-standing 95xx series as a more sustainable option.

These new bi-elastic interlinings are made from rPET and are designed to work well with various modern fabrics, including pure cotton, T/C, flannel, oxford, cotton & linen blends, seersucker, jersey, and all types of stretch knits. The RCY 99xx series retains the natural feel, texture, and shape of these fabrics while adding new creative possibilities to shirt design.

With a weight range of 30-150 g/m², the RCY 99xx series is versatile enough for many shirt styles, including men’s casual shirts, women’s blouses, polo shirts, sports shirts, and denim shirts. This flexibility allows designers and manufacturers to meet changing market demands while maintaining sustainability.

Freudenberg’s Apparel House of Sustainability (HoS) supports customers in reaching their sustainability goals. By promoting sustainable innovation and introducing new solutions each season, the RCY 99xx series from HoS’s Recycled General Interlinings category highlights Freudenberg’s dedication to sustainable impact and ongoing innovation.
