BREVIOL® TECHNOLOGY INTRODUCTION OF THE THE MOST ECOLOGICAL, BREVIOL® DENIM SUSTAINABLE, TECHNOLOGY The BREVIOL® DENIM TECHNOLOGY (BDT) is based on a polymer which react with SAFE AND EASY WAY the dyestuff as well as the fi ber, forming a polymer net or chain that creates a ring resin eff ect, accelerating the exclusive ring FROM COTTON TO JEANS characteristics. The BREVIOL® DENIM TECHNOLOGY (BDT) is used in the Indigo and Sulfur dyeing processes, reducing the amount of water which is used after the dyeing process to remove the unfi xed which would normally go to the waste water treatment facilities.

This technology not only cares for the planet, off ering a cleaner water-treatment concept, but is a cost-saving solution, using less water in the process and reducing the amount of dyes. EFFICIENCY SHADE The BREVIOL® DENIM TECHNOLOGY (BDT) ensures The BREVIOL® DENIM TECHNOLOGY (BDT) gives that almost 100 % of the applied dyestuff remains the possibility – even only with indigo – to obtain on the yarn, versus the standard process, where 15 shades differentiating from more “reddish-clean” to to 25 % of the is eliminated by washed-off more “greenish-greyish”

ECOLOGY CONTRAST Due to the reduction of the rinsing water flow Thanks to the BREVIOL® DENIM TECHNOLOGY and much less water contamination, makes the (BDT) performance, the generated effects are very BREVIOL® DENIM TECHNOLOGY (BDT) a more unique, distinctive and contrasting/fashionable. ecological and sustainable process compared to The fastness is improved. the current technologies. SUSTAINABILITY FASTNESS All mentioned characteristics make the BREVIOL® Using the BREVIOL® DENIM TECHNOLOGY (BDT), DENIM TECHNOLOGY (BDT) in pure indigo, top- even without rinsing the dye, the washing fastness ping, bottoming, black-denim and color-denim a is much better than usual. more sustainable process with good fastness, more ecological due to their advantages of water savings and a much more cleaner process. PROCESSES

PURE INDIGO Process Bottoming, reddish and clean COST SAVINGS shade, more , intensity and good wash fastness properties. Eff ects in garments such as sand-paper or mechanical eff ects are easy to be applied. Process Topping, slightly greenish shade, high intensity and good wash fastness, ECOLOGICAL LESS BLEEDING better wash-down results. CONCEPT LESS BACK STAINING

BOTTOMING BDT blocks the solubility of the BREVIOL® during the indigo dyeing. Due to physical DENIM bonding and eff ects on the yarn, better ring eff ect is achieved (indigo is more TECHNOLOGY superfi cial). More darker shades and not contamination. Not loss of the sulfur dye during the indigo dyeing. LESS WASTE WATER FASHION EFFECTS CONTAMINATION TOPPING Practically 100 % of the dyestuff remains on the surface of the yarn, and is not eliminated during the rinsing process, more safe and diff erentiated than the WATER SAVINGS traditional topping process. Excellent contrast in stone-washed garments. BENEFITS:

• Water Savings advantages BLACK-DENIM • Control of Indigo shade BDT provides a very dark shade and good fastness, without metallic aspect and • Less Waste Water Contamination, including water color neither bronzed appearance. Tendering • Less energy and water consumption eff ect practically disappears Very low contamination of the waste water enables • Provide Reduced Indigo and Sulfur Dye Usage & Cost Savings to work non stop. • Less & Even Zero Dye Bleeding during Re-beaming, Sizing & Finishing Processes • Provide an Ecological Overdyeing Process with / without a Steamer • Reduce Fabric Back Staining COLOR-DENIM • Topping use less sulfur dyes, better fastness and clean weft in. BDT is an easy way that gives very good uniformity of the dyes among diff erent • Improve Dye Fastness properties & the ability to produce darker Dye shades lots with a guaranty of a total dyestuff • Produce Special and better Ring Dyeing Eff ects shade development. • Total elimination of bronzing eff ect BREVIOL® DENIM TECHNOLOGY SAVINGS BREVIOL® DENIM TECHNOLOGY EXAMPLE OF PROCESSES
