Solvent-free raw materials for textile coating from Bayer

"The fashion industry is also moving toward more environmentally-friendly materials, and we can support this trend with our dispersions," says Michaelis. For example, the Oeko-Tex standard 100 can be achieved with coatings based on these dispersions. This is an independent system that grades textile raw materials, intermediates and end products in all stages of processing in terms of the harmful substances they contain.

For example, jeans coated using Impranil DLN or the high-solids variant Impranil DL 1380 have a pleasant, soft and high-quality feel. The coatings also provide a high level of design freedom and enable gloss, color and glitter effects. At the same time, the polyurethane coating survives more washes than other coatings.

Finally, the dispersions can also be helpful in protecting certain areas during the stonewashed process, for example, where the bleached effect is not to be as pronounced as on the rest of the jeans.

Products such as Impranil DL 519, Impranil DL 1554 and Impranil DAH are also used to produce fashionable and low-emission synthetic leather applications for bags, jackets, belts, shoes and clothing.

High performance in technical applications

Areas of application for technical textiles include conveyor and other transport belts as well as bellows used to protect the joints of industrial robots, for example. Appropriate textile coatings must be extremely abrasion-resistant while at the same time very flexible.

For a long time, this combination of characteristics could only be achieved using solventborne systems. However, waterborne, cosolvent-free formulations with products from Bayer MaterialScience now meet the most stringent requirements in this respect.

This also benefits other applications besides industrial production engineering, including textile protective gloves, safety vests, lifeboats and tents.
