Gentle Power Bleach™

Sustainable bleaching at low temperature and neutral pH

New high-quality, environmentally friendly peroxide bleaching process

This revolutionary, enzyme-based peroxide bleach allows low temperature bleaching (65ºC) of textiles at a neutral pH range

This outstanding new system excels in its capability to process textiles more sustainably whilst delivering textile goods with an enhanced quality

Textile Effects

Perfect preparation

Gentle and versatile bleaching at its best

• Suitable for most fibres and blends

• Perfect preparation ready for dyeing on cotton

• New possibility for bleaching denim in garment wet processing

• Excellent full white levels on regenerated cellulosic fibers and polyamide

• Applicable on all closed discontinuous equipments such as jet, jigger, overflow and cheese dyeing machines

Technology

Textile Effects

Soft handle

Gentle in application, soft and smooth to the touch

• Extremely soft, bulky and natural handle

• The effect is fast and permanent

• The crease recovery properties are excellent;much less crease marking during processing

• Sewability (needle resistance) and stretch are improved

Maximum strength of the textile material with the lowest degree of chemical damage on cotton seen in the industry Quality

Textile Effects

Brilliant color

Giving you the colors that Designers want to see

• Noticeably brighter shades

• Savings in dyeing costs possible

• Similar or even better wash, water and rubbing fastness properties

The perfect pretreatment for excellent dyeing results Quality

Textile Effects

Process optimizationReduce consumption

• Savings in energy consumption by about 40%

• Cotton weight loss is reduced

• Cotton remains naturally soft and bulky - new unattained softness levels are reachable

Competitive

Textile Effects

Process optimization Right First Time

• No danger of residual alkali

• Less swelling of the natural fiber

• Avoidance of costly and resource consuming re-works

• Lower risk of crease marking in piece good and garment processing

CompetitiveSupporting an improved reproducibility

Textile Effects

Responsible technologySaving energy and water resources for future generations

• Unique in the field of energy reduction

• Effluent salt load is reduced

• All auxiliaries used show an excellent bio-elimination, free of APEO and AOX

• Life Cycle Assessment: 25% lower Climate Change impact compared to conventional process (CO2 / per kg bleached cotton)

Gentle Power Bleach™ contributes towards making the textile industry more sustainable

Gentle Power Bleach™ on reg. CEL fibers

ONE Formula for all regenerated Cellulosic Fibers

Perfect Preparation – Gentle Bleaching as its best

Soft handle and improved reproducibility

• Enzymatic peroxide bleaching and whitening at low temperature and neutral pH• Excellent full white levels with UVITEX® optical brighteners.

• Extremely good fiber protection, no chemical damage on regenerated cellulosic fibers• No negative impact at all on the characteristic property of non-fibrillating and low-fibrillating lyocell fiberssuch as TENCEL® A 100 and TENCEL® LF by maintaining the resin finishing.

• Outstanding soft and bulky handle• Excellent crease recovery and enhanced fabric properties such as burst strength and stretch.

Improved reproducibility – Right first time production• No neutralizing required; No danger of residual alkali, the main cause of faulty dyeing.• Less fiber swelling avoids channeling effect in yarn packages.• Lower risk of crease marking for piece goods and garments.
