Lenzing introduces new resource-efficient dyeing approach for TENCEL™ Lyocell fibers

The new approach reduces water and energy usage in creating similar wash-down aesthetics, previously only achievable through a resource-intensive denim dyeing and bleaching process

Ideal for use in yarns and fabrics made of TENCEL™ Lyocell fiber or TENCEL™ Lyocell fiber with REFIBRA™ technology, the approach helps elevate the versatility of fabrics and unleashes design possibilities in ready-to-wear and knit apparel

Easily compatible with existing machinery in fabric mills, the new approach can enhance energy efficiency in the production process, enabling greater cost-savings and sustainability in the supply chain

Lenzing – Lenzing Group, a leading global producer of wood-based specialty fibers, has introduced a new approach that covers yarn pre-treatment and knitting technique to achieve aesthetics that resemble the wash-down effects of traditional dyeing in ready-to-wear and knit garments. To address the pollution caused by dyeing and finishing in the textile industry, the new approach will significantly reduce environmental impact and is ideal for use on pre-treated fabrics and yarns made with TENCEL™ Lyocell fibers. The approach also complements the wet-processing and production facilities of fabric mills, bringing added benefits for value chain partners.

One-step dyeing process significantly reduces water and energy consumption

In traditional dyeing, multiple washes using a significant amount of water, energy, dyes and chemicals may be required to achieve a designated shade of color. With the new approach, only one round of dyeing is required, reducing water, energy and chemical usage by up to 50%, 40% and 90% respectively[1].

“As consumers become more conscious of the environmental footprint of their purchases, designers and manufacturers are seeking innovative ways to ensure that the materials and production processes deployed have a low environmental impact, while expanding design possibilities,” said Rex Mok, Vice President of Fiber Technical Marketing and Development at Lenzing. “Our new approach can create wash-down aesthetics or vintage looks on any knit fabric without water-intensive bleaching processes. By overcoming the limitations of traditional dyeing, our new approach is a resource-efficient alternative that helps translate into greater sustainability and more competitive operational costs for fabric mills. We will continue to work with mill partners to drive wider adoption of the new approach and explore new applications within the textile value chain.”

Unleash unlimited design possibilities in knit apparel and denim-looking garments

With the new approach’s direct application to TENCEL™ Lyocell fibers or TENCEL™ Lyocell with REFIBRA™ technology, different shades of color, wash-down or fade-out effects can be customized. This makes it ideal to produce ready-to-wear, knit apparel and denim-looking garments in various color shades.

Enhance production efficiency and increase cost-savings for value chain partners

Existing regular, organic, or natural dyes used by yarn makers and fabric mills are compatible with the new approach. As yarn and fabric processed with the new approach do not leave dye residue on machines, the same machinery can be used continuously for the production of fabrics or garments of different colors. With machine down-time being minimized when changing color lots, production delays will be shortened, allowing yarn makers and fabric mills to save costs while enhancing production efficiency and sustainability.
