Abstract

Textiles are an important part of our everyday life, and the pace of production has increased worldwide, especially in the past few decades. The textile industry is one of the most polluting industries, with the dyeing process being the step with the highest environmental impact. There has been a rise of awareness among consumers of the issues related to fast fashion and the environmental impact that it has. This has led to a demand for bio-based and biodegradable fibres as the consumers behaviour has started to be affected.

The impact of the dyeing process could be lowered through spindyeing, which is already used for colours in synthetic fibres that are produced in big quantities. In our research we have applied this method to dry-jet wet spinning of man-made cellulose fibres using different Vat dyes (i.e. Indigo, Indanthren BrGreen FFB Coll, Indanthren Red FFB Coll, Cibanon Olive BMD & B2G MD, Cibanon Brilliant Orange 3R MD, and Cibanon Marineblau).

The dyed fibres showed high fibres properties comparable to undyed fibres with tenacities up to 53,91 cN/tex and elongation up to 11,6 %. The wash and rubbing fastness of the knitted fabrics were studied and compared to conventionally dyed fabrics.
