DyStar is ready for ACLE
DyStar will showcase its full range of dyes and auxiliaries for wet-end leather and fur processing at its "World of Leather" exhibit at the All China Leather Exhibition (ACLE) in Shanghai in September.
The exhibit centres on high-fashion, heavy vegetable retanned leathers for classic men’s shoes, bags and belt leather, produced with recipes incorporating Eskatan GLSW, Cutapol LAP and Cutapol TIS-VT.
The company claims that Cutapol LAP significantly improves the elasticity of the grain, so even leather produced with strong retans can be processed without grain cracks.
At the same time, it says a combination of Cutapol TIS-VT and Eskatan GLSW gives especially soft, full leather with an excellent tight grain. Tannit REP can be added to retanning floats to enhance grain tightness.
A melamine resin from DyStar’s new range of powder syntans with a strong filling effect on the bellies and shoulder areas improves cutting yield.
DyStar is also exhibiting articles containing little or no vegetable tanning agent with good fastness to light and heat. Tannit STP, a liquid syntan for a broad spectrum of applications, gives a strong filling effect and outstanding fastness properties.
DyStar has also continued to extend its compact range of dyes for leather and fur. Alongside a wide variety of shades that can be dyed readily with combinations of its homogeneous dyes, the exhibit includes new dyes such as Solvaderm Brown MF-GO. This warm, neutral, mid-brown has no reddish cast and is particularly suitable for shoe upper leather. Its main features are good penetration, high build-up and, DyStar insists, excellent value for money.
Another recent development is Solvaderm Grey MC-CC, which meets the demanding specifications of the automotive industry. This dye has a neutral to slightly greenish cast and can be used for a wide range of shades from pale pastels with excellent penetration to a strong middle grey. A second new grey dye, Solvaderm Grey MC-GB, also has excellent fastness properties. It has a blue cast and excellent penetration and can be used for both pale and heavy shades of grey. In top dyeing it can also produce a strong anthracite. This dye is suitable for all types of leather, including automotive, clothing, upholstery, shoe and bag leather.
Brilliant deep black shades on full-grain and velour leather and fur are obtained with another new dye: Solvaderm Black MC-FK. Its neutral shade and high fastness properties are suitable for penetration dyeing and, above all, top dyeing. One special feature is its suitability for double-face dyeings with wool resist.
