Q1: What is the primary application area for Viscofil Green GVDN 20?
A: Viscofil Green GVDN 20 is specifically developed for coloring viscose and other regenerated cellulose fibers, including lyocell and modal, during the spinning or post-spinning dyeing process. It offers excellent compatibility with standard viscose processing conditions and delivers consistent, buildable green shades.
Q2: Is this pigment suitable for food-contact textile applications?
A: Viscofil Green GVDN 20 is not classified as a food-contact pigment. It is formulated for industrial textile coloration and is not intended for direct, prolonged contact with food or consumables. For such applications, Clariant offers separate regulatory-compliant product lines subject to specific migration and safety assessments.
Q3: How does Viscofil Green GVDN 20 perform in terms of lightfastness and washfastness on viscose?
A: When applied under recommended process conditions, Viscofil Green GVDN 20 delivers good to very good lightfastness and washfastness on viscose substrates. Performance is optimized when combined with appropriate aftertreatments, such as cationic fixing agents, and may vary depending on fiber morphology, liquor ratio, and thermal treatment.
Q4: Can this pigment be used in combination with other Viscofil dyes?
A: Yes — Viscofil Green GVDN 20 is fully compatible with other products in the Viscofil range and is designed for use in mixed-shade formulations. It exhibits predictable build-up behavior and minimal cross-interference, supporting reproducible shade matching across diverse viscose processing setups.
