Process for reusing silk textiles in thermal insulation developed

February 5th, 2021 / By: / EcoNote

Freudenberg Performance Materials and Ratti, the Italian fashion textile company, have been working together on sustainability projects. The first fruit of this collaboration is a process for reusing silk textiles in the manufacture of high-performance thermal insulation. 

The practice of using recycled materials from other industries, such as post-consumer PET bottles, has been common practice in the textile industry. Freudenberg is reusing silk from clothing to produce thermal insulation made from 70 percent reused silk, which Ratti then markets.

Freudenberg´s solvent-free manufacturing process for the waddings significantly reduces the environmental impact of the new process. Airlaid technology plays a key role in the reuse of silk textiles, enabling Freudenberg to produce waddings with a three-dimensional structure from this material. This leads to the formation of countless tiny air chambers, which give the padding excellent thermal insulation properties and breathability. 

Its high-dimensional stability and wash resistance, as well as durability, make this wadding well suited for environmentally conscious outdoor enthusiasts.

Freudenberg Performance Materials is a global supplier of technical textiles for a range of markets and applications. The company is based in Germany.
