Lenzing Group stated in a release that the approach complements wet processing and production equipment of fabric mills. This brings added value to partners along the value chain.
Lenzing’s innovative sustainable method for dyeing garments is suitable for pre-treated yarns and fabrics made of Tencel Lyocell fibres.
This innovation reduces the use of water, chemicals, and energy by as much as 50%, 40%, and 90%, respectively.
This method reduces downtime for machines as it does not leave any dye on the machine.
In the traditional method of dyeing, several washes involving a considerable amount of dyes, energy and chemicals are required in order to obtain a desired colour. The new method only requires one dyeing round, which reduces water, energy and chemical consumption by as much as 50%, 40% and 90%, respectively.
Rex Mok is vice president for fibre marketing, development and technical at Lenzing, said: “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. Our new method can produce vintage or wash-down looks in any knit fabric, without the need for water-intensive processes. In addition to overcoming traditional dyeing limitations, the new method is also a more resource-efficient option that can translate into greater sustainability for mills and lower operational costs. 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.”
With the new approach’s direct application to Tencel Lyocell fibres or Tencel Lyocell with Refibra technology, different shades of colour, wash-down, or fade-out effects can be customised. It is ideal for producing ready-to wear, denim-looking clothing and knitwear in different colour shades.
All existing natural, organic or regular dyes that are used in yarn and fabric production can be adapted to the new process. The new method does not leave any dye residues on the machines. This allows the machine to be continuously used for producing fabrics and garments in different colors. The machine will not be down for long when switching colour lots. This reduces production delays and allows yarn and fabric manufacturers to cut costs.
