INDIGO, A SPECIAL CASE:

HOW TO WIN THE IN-OUT GAME

Denim takes a special place among modern textiles: The indigo-blue color and fashionable wash-out effects make all the difference. Long before preparing the dyeing bath, customers can benefit from our special know-how in cotton, from production of the denim fabric throughout all subsequent process steps. From spinning to garment finishing, Pulcra Chemicals offers products that assure optimized processes and healthy cost-benefit ratios. Our weaving and pretreatment auxiliaries offer telling advantages, especially the products for continuous pretreatment of cotton and cotton mixes. They stand out particularly for their low-foaming, rapid wetting and optimal emulsifying properties and have made us the market leader worldwide. Pulcra Chemicals sets standards in softening too – with processing aids for making-up - which improve the touch while protecting the fabric from damage.

 

THE MOST ECOLOGICAL, SUSTAINABLE,

SAFE AND EASY WAY FROM COTTON TO JEANS ...

The Breviol® Denim Technology (BDT) is based on a polymer which react with the dyestuff as well as the fiber, forming a polymer net or chain that creates a ring resin effect, accelerating the exclusive ring dyeing 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 unfixed dyes which would normally go to the waste water treatment facilities. This technology not only cares for the planet, offering a cleaner water-treatment concept, but is a cost-saving solution, using less water in the process and reducing the amount of dyes.

PROCESSES

 

Pure indigo

Process Bottoming, reddish and clean shade, more ring dyeing, intensity and good wash fastness properties. Effects in garments such as sand-paper or mechanical effects are easy to be applied. Process Topping, slightly greenish shade, high intensity and good wash fastness, better wash-down results. 

Bottoming

BDT blocks the solubility of the sulfur dye during the indigo dyeing. Due to physical bonding and effects on the yarn, better ring effect is achieved (indigo is more superficial). More darker shades and not contamination. Not loss of the sulfur dye during the indigo dyeing. 

Topping

Practically 100 % of the dyestuff remains on the surface of the yarn, and is not eliminated during the rinsing process, more safe and differentiated than the traditional topping process. Excellent contrast in stone-washed garments. 

Black-Denim 

BDT provides a very dark shade and good fastness, without metallic aspect and neither bronzed appearance. Tendering effect practically disappears Very low contamination of the waste water enables to work non stop. 

Color-Denim

BDT is an easy way that gives very good uniformity of the dyes among different lots with a guaranty of a total dyestuff shade development.
