Livinguard +DYE

Innovative additive that reduces the number, duration & temperature of washing and soaping cycles needed to remove unfixed dyes in an otherwise conventional wet dyeing process for cellulosic fibers (cotton/viscose, silk and cotton/Lycra blends). Another step towards a more sustainable future through a game-changing environmental impact from water and energy savings – all while providing disruptive economics for mills and compatibility with existing equipment.

Technology

Permanently fixing hydrolyzed dyes on the textile

Dyeing

As alkali is added to the dyebath, dyes react with the cellulosic fiber (forming covalent bonds) – however dyes are also hydrolyzed with water. The hydrolyzed dyes only adsorb weakly onto the fiber surface.

Neutralization

In the neutralization step, the weakly adsorbed hydrolyzed dyes start to bleed out as their adsorption to the fiber surface weakens.

Conventional Washing

Extensive and repeated washing & soaping is required to remove hydrolyzed dyes that have not formed a covalent bond with the fiber to achieve desired color fastness.

Livinguard +DYE

The added Livinguard +DYE permanently adsorbs to the fiber. Hydrolyzed dyes are attracted by the cationic charge and strongly bound. No additional washing steps are required.

Benefits

Our technology provides environmental impact and disruptive economics for textile producers

Up to 10%
cost savings

From reduction of water, energy, dyestuff & auxiliaries and simplified RO process

Up to 30%
productivity increase

From reduction of total process time required from dyeing over soaping & washing post dyeing to finishing

Up to 25% production capacity increase

Added production capacity without requiring any new capital investment into new equipment

Up to 30%
energy savings

From fewer washing cycles carried out at room temperature and eradication of RO treatments to recover salt

Up to 25%
of water savings

From reduction of soaping & washing cycles required post dyeing to extract unfixed dyes

Chemical additive optimization

Partial or complete substitution of other chemical additives (e.g. fixing agents) from the process

Lower dosage of dyestuffs

Up to 20% lower dosing of dyestuffs and lower dye burden in the effluent due to higher dye uptake

Enhanced production resilience

Higher production up-time even during water shortages

Cost-effective implementation

No capital expenditures needed, fully compatible with existing equipment

VALIDATION

Livinguard  +DYE – Cotton has been extensively tested with great results and was able to match the fastness requirements of the established conventional dyeing process.

Advantage

Overview of process flow for conventional vs. Livinguard +DYE (exemplary process)

Conventional process

~65%

of water usage and processing time are spent on washing unfixed dyes out of the treated fabric post dyeing

~80%

of energy consumption is required to carry out washing and soaping at high temperatures

Validation

Livinguard +DYE has been tested externally with great results

ISO 105-X 12:2016

Method for determining the resistance of the color of textiles to rubbing off and staining other materials.

Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth

  • Livinguard +DYE with same dry rubbing fastness performance as conventional process across all 4 colors tested

  • Livinguard +DYE with same wet rubbing fastness performance for red & navy, slightly lower performance for yellow & turquoise (still above standards for most brands at 3-4)

SO 105 C06:2010

Methods for determining the color resistance of textiles in all forms to domestic or commercial laundering procedures used for normal household articles using a reference detergent.

  • Livinguard +DYE with overall comparable washing fastness performance across all 4 colors tested

  • Livinguard +DYE meets or exceed standards for most brands

AATCC EP 6-2016

Measurement and handling procedures for color (or colored appearance) by instrumental means (reflectance, transmittance measurement, and related calculations)

  • Color deviations observed well within acceptable limits

Impact

Livinguard +DYE can have a transformative impact on the world

Our technology is a sustainability game changer - assuming 10% of the addressable production moves to Livinguard's +DYE technology will yield massive water and CO2 savings
