Global denim innovator ISKO has teamed up with U.S. apparel brand NYDJ to expand production of Re-New™ Denim, a sustainability-focused line that combines advanced stretch technology with recycled materials, marking a significant push toward circular manufacturing in the denim sector.
The collaboration brings together ISKO’s Reform™ fabric technology and recycled fibers sourced through textile recycling platform RE&UP, creating a vertically integrated system that converts discarded denim into new, high-performance garments. The initiative reflects growing industry efforts to reduce environmental impact while maintaining product quality and durability.
Re-New™ Denim is positioned as a premium offering, engineered to deliver elasticity, shape retention and long-lasting comfort. By incorporating recycled cotton and polyester into its construction, the product reduces dependence on virgin raw materials, particularly conventional cotton, which is associated with high water consumption and environmental strain.
The production process begins with the collection of post-consumer and post-industrial denim waste. These materials are processed by RE&UP, which separates blended fibers and regenerates them into reusable raw inputs. Cotton is transformed into next-generation recycled fiber, while polyester components are converted into new synthetic material suitable for textile applications.
These recycled inputs are then supplied to ISKO, where they are integrated into the company’s Reform™ fabric platform. Known for its bi-stretch properties, Reform™ technology allows denim to stretch and recover without losing its original shape, addressing a key challenge in sustainable denim production—ensuring performance matches that of conventional fabrics.

NYDJ uses the resulting fabric to manufacture finished garments under its Re-New™ label, maintaining its focus on fit, comfort and wearability. The brand, known for its shaping denim designs, positions the collection as an intersection of sustainability and everyday functionality.
The partnership comes at a time when the global fashion industry is under increasing pressure to adopt circular business models. Regulators, particularly in Europe, are introducing policies aimed at reducing textile waste and encouraging recycling, while consumers are demanding greater transparency and environmental responsibility from brands.
Denim, one of the most widely consumed apparel categories, has become a focal point in sustainability discussions. Traditional denim production involves resource-intensive processes, including water-heavy cotton cultivation and chemical dyeing methods. As a result, brands and manufacturers are investing in innovations that can lower environmental impact without compromising on quality.
Despite progress, large-scale textile recycling remains complex, especially for fabrics that combine natural and synthetic fibers. Technologies capable of efficiently separating and reprocessing these blends are critical to advancing circularity in the industry. RE&UP’s system addresses this challenge, enabling a wider range of materials to be recycled and reused in new products.
Industry analysts say collaborations like the ISKO-NYDJ partnership are becoming essential as companies look to scale sustainable solutions. By aligning capabilities across the value chain—from fiber recovery to fabric engineering and garment production—such partnerships can accelerate the transition to circular fashion.
NYDJ has indicated that a substantial share of its product portfolio already incorporates sustainable materials, including recycled fibers and responsibly sourced cotton. The Re-New™ initiative represents a continuation of these efforts, with a focus on expanding circular practices across its denim range.
ISKO, part of Turkey’s Sanko Group, has also made sustainability a core pillar of its strategy, investing in research and development to create fabrics that meet both environmental and performance standards. Its collaboration with NYDJ underscores the role of material innovation in driving change across the apparel sector.
While financial terms of the partnership have not been disclosed, the move signals a broader shift within the denim industry toward integrated, circular production systems. As brands face mounting regulatory and consumer pressures, initiatives like Re-New™ Denim are expected to play an increasingly important role in shaping the future of fashion.
