A finishing procedure for LENZING™ Lyocell (ITMA 2023 project lead Martin Köllerer from Global Technical Marketing of Lenzing AG) 

Fibrillation of LENZING™ Lyocell:

LENZING™ Lyocell and LENZING™ Lyocell RB fibers fibrillate under conditions of wet abrasion, creating micro-fibrills on the surface of the fiber which remain attached to the main body of the fiber, the development of these micro-fibrills occurs mainly on the fabric surface.

Fibrillation is the longitudinal splitting of a single fiber into microfibers of 1-4 microns in diameter. The splitting occurs as a result of wet abrasion against fabric or metal, using jet rope or garment wet processing procedures and can be used to engineer a range of interesting fabric aesthetics.

Aesthetics: Cool & Silky; Semi- Peach, Peach

For all aesthetics it is key to control the fibrillation of LENZING™ Lyocell & Lyocell RB

Mechanical polishing developed by Lenzing is a suitable procedure to control the fiber fibrillation of LENZING™ Lyocell. It is an alternative cellulase(enzyme) free finishing procedure to create outstanding cool & silky knitted fabric aesthetics, stable to the home laundry, effectively reducing chances of pilling.

What is required?

Jet dyeing machines or washing systems like Biancalani AIRO® with good fabric reorientation properties to create an even & sufficient degree of fibrillation for the preparation & the dyeing process.

Suitable resin finishing systems to control the chemical fibrillation properties and to prevent further fabric fibrillation through domestic washing.

Tumbling machines such as Biancalani AIRO® versions that can finalize the fabric finishing to create the clean surface effect.

Mechanical polishing process by Lenzing can be adapted for fabrics made of LENZING™ Lyocell fibers.
