These collaborations mark a major milestone in the advancement of sustainable luxury materials and showcase the potential of Brewed Protein™ fibers in various high-end applications.

The collaborative fabrics and yarns are now available for purchase and custom development.

Marzotto x Spiber
Marzotto Wool Manufacturing S.r.l., established in 1836 and renowned for its high-quality worsted wool, has collaborated with Spiber to unveil a fabric blending 30% Spiber’s Brewed Protein™ fibers with 70% wool for the first time after approximately two years of joint development. The fabric, suitable for suiting, is now available for purchase, and both companies are eager to extend their collaboration into the future.

Filatura Papi Fabio x Spiber
Filatura Papi Fabio S.p.A., established in 1890, is a renowned Italian spinning mill with over 130 years of experience in producing high-quality woolen and worsted yarns. After collaborative development, Papi Fabio and Spiber have unveiled their first yarn products, featuring blends of Spiber’s Brewed Protein™ fibers and RWS Ultrafine wool. The yarns, suitable for knitting and weaving applications, are now available for purchase, and both companies anticipate expanding their collection of Brewed Protein™ blended yarns in the near future.

RD Gruppo Florence x Spiber
RD Gruppo Florence and Spiber have begun collaborating on synergic technical research with the aim of giving concrete form to sustainable luxury fashion, unveiling their first women’s and men’s prototypes at Pitti Filati made by some of the Group’s companies: Mely’s Maglieria, Antica Valserchio and Ideal Blue.

The womenswear prototype is knitted by Mely’s Maglieria with Brewed Protein™ yarns, developed in synergy with VIMAR1991. Brewed Protein™ fibers, wool, polyamide, and cashmere-blended fancy yarns have been custom developed to enhance the aesthetic features of the material, opening new possibilities in the personalization of garments and their components.

The menswear prototype is woven by Antica Valserchio with Brewed Protein™ yarns. The prototypes are manufactured by Ideal Blue. The jacquard fabric is produced with the “Graphic Mapping” technique, considering the placement of the graphics on patterns in order to minimize waste and evolve the production process, elevating the engineering content from a product point of view.


The fabrics and yarns used in these prototypes are now available for custom development.
Both companies anticipate further collaborations and upcoming technical solution launches in the near future.
