The increased demand for wool denim applications is reflected in the dedicated new Wool Lab edition featuring 105 swatches and a new toolkit from Woolmark.

The Wool Lab Denim Edition is being presented through two books divided into seven categories – A Revised Classic, Special Treatments, Denim Shirting, The Denim Suit, Signature Denim, Thread Rebels, and Denim-Inspired Knits and Jerseys.

By integrating wool fibres into traditional denim construction, the fabric is elevated to a premium, high-performance level, enabling brands to offer customers innovative and highly desirable products.

“We have seen an ever-increasing demand for wool denim swatch requests through The Wool Lab over the past four years,” says Woolmark’s general manager for processing innovation and education extension, Julie Davies. “The timeless appeal of denim is enriched with wool’s skin-friendly softness, breathability, versatility and durability, resulting in wardrobe essentials that transcend the ordinary.”

The dedicated Wool Lab features new blends such as wool-hemp, wool-lyocell and 100% extrafine wool spun with premium fibres like silk, cashmere or paper – offering unique benefits and applications for those on the cutting edge of innovation. Furthermore, wool’s natural thermoregulating properties make wool denim suitable for all seasons, providing immediate warmth and reducing the initial chill often felt with cotton jeans.

The Wool Lab Denim Edition is backed by a comprehensive technical toolkit, developed in collaboration with a global network of textile experts. It provides in-depth insights into wool’s performance in denim applications, offering guidance on fibre selection, fabric construction, finishing techniques and sustainability practices. With this expert-driven resource, designers and manufacturers can explore the full potential of wool in denim, combining innovation with technical precision.
