New fatliquor for soft articles from TFL

04/05/2011
Specialty chemicals manufacturer TFL has said a new product, Coripol ALF, is a “best in class” lecithin-based fatliquor featuring enhanced properties. In addition to good light- and heat-fastness, this anionic fatliquor supports good tensile strength, as well as tear and stitch-tear resistance.

The new product is designed for the production of all kinds of soft articles including shoe nappa, garment, furniture leathers and splits. Its softening power and good gravimetric fogging performance make it especially suitable for the pre-fatliquoring and main-fatliquoring of automotive articles from both chrome-free and chrome-tanned stock, TFL said.

Coripol ALF is based on a combination of enhanced natural and synthetic softening agents. The company added that its special formulation means it features a low viscosity for better transportation in road tankers, is easy to handle and emulsify in water and it has good stability to troublesome hard water and the most commonly used electrolytes.

The fatliquor is free of mineral oil and "almost completely based on sustainable raw materials" and since it exhausts well, it does not noticeably raise the COD of the tannery waste water.
