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.
A Tecnologia Breviol® Denim (BDT) é baseada em um polímero que reage tanto com o corante quanto com a fibra, formando uma rede ou cadeia de polímeros que cria um efeito de resina anular, acelerando as características exclusivas de tingimento do anel. A Tecnologia Breviol® Denim Technology (BDT) é utilizada nos processos de tingimento de índigo e enxofre, reduzindo a quantidade de água que é utilizada após o processo de tingimento para remover os corantes não fixados que normalmente iriam para as instalações de tratamento de águas residuais. Esta tecnologia não só cuida do planeta, oferecendo um conceito de tratamento de água mais limpo, como é uma solução econômica, utilizando menos água no processo e reduzindo a quantidade de corantes.
- Water Savings advantages
- Control of Indigo shade
- Less Waste Water Contamination, including water color
- Less energy and water consumption
- Provide Reduced Indigo and Sulfur Dye Usage & Cost Savings
- Less & Even Zero Dye Bleeding during Re-beaming, Sizing & Finishing Processes
- Provide an Ecological Overdyeing Process with / without a Steamer
- Reduce Fabric Back Staining
- Topping use less sulfur dyes, better fastness and clean weft in.
- Improve Dye Fastness properties & the ability to produce darker Dye shades
- Produce Special and better Ring Dyeing Effects
- Total elimination of bronzing effect
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.
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.
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.
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.
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.
