Lenzing Introduces Industry’s First Innovation To Mitigate Discoloration Of Cellulosic-based Garments During Heat Molding

New York, NY – June 5th, 2023 – Lenzing Group, a leading global producer of wood-based specialty fibers, has introduced a new processing solution that mitigates the yellowing of garments and fabrics made with wood-based cellulosic fibers during high-temperature production processes. With an initial rollout that targets innerwear and subsequently outerwear and ready-to-wear garments, the solution is the first in the industry to address the technical challenge during the garment molding process. Lenzing is also taking on next steps to explore other potential applications, such as in heat seal processes of garments, and seamless stitching processes that involve heat seal adhesive tapes and bonding machines to replace traditional sewing.

Discoloring and yellowing issues caused by high-temperature molding have traditionally been inevitable during the garment production process. While chemicals could be used to minimize discoloring issues in synthetic fibers, this method does not work as effectively as it does in wood-based cellulosic fibers. With Lenzing’s proprietary solution, such a challenge is mitigated, eliminating the bottleneck fabric mills experience during the production and dyeing of light-colored garments made of wood-based cellulosic fibers.

Leveraging the new innovation, Lenzing’s mill partners can now benefit from the adoption of a broader spectrum of colors and shades, bringing more diversified fabric and garment offerings to consumer brands. Given the diversified needs among different mill partners, Lenzing’s technical experts will work closely with fabric mills to provide a technical analysis of fibers and fabrics, recommendations, and ongoing support through the end-garment stage.

Li Wei, Product Development Manager, at Yelin, said, “Our customers have been positive about the visible improvement of the yellowish issues in fabrics during the high-temperature molding process. Lenzing team’s processing solution and technical support have made our lives easier, allowing us to find the sweet spot for different combinations of fabrics and colors.”

During the initial phase, the proprietary technology will be used in the production of seamless lingerie and shapewear globally, with a proactive strategy to introduce the technology to outdoor apparel and other ready-to-wear garments thereafter. Waterproof garments, windbreakers, jackets, and other weatherproof clothing that are produced using a stitch-free technique or heat seal bonding will also benefit from the increased color and design possibilities.
