TFL introduces new fatliquor to help tanners meet automotive leather needs
26/06/2015
On launching the new product, TFL said these increased demands, especially regarding prolonged heat fastness in chrome-free leathers, have come to represent a challenge for tanners in terms of fatliquor use in the wet-end process. The company has also said there is a trend towards firmer, tighter and more compact automotive leather.
TFL’s view is that Coripol ESU is able to meet these demands, producing “soft articles with a silky handle, good grain tightness, a uniform milling pattern, low fogging and good and uniform dyeability”, with leathers also meeting light and heat fastness requirements, both in wet blue and chrome-free leathers. The product also meets restricted substance list and chemical regulation requirements.
It can be used alone or in combination with other suitable fatliquoring products to make a variety of soft articles, either from wet blue or wet white hides. In addition, Coripol ESU exhausts well by acidification of the fatliquor bath, which helps to reduce COD and BOD values in tannery wastewater, TFL has said.
