Sažetak
The paper will present an experiment of vat dyeing of specific fabrics with protective, fire retardant properties that have a high content of aramid fibres in their composition. The research was performed on fabric samples that differ in raw material composition and aramid content. Also, the samples were dyed in raw from (group 1) as well as after pre-treatment with alkaline scouring (group 2). Based on the values obtained by measuring the LOI index, it was shown that the selected fabrics meet the properties of inherently FR fabrics. Dyeing was performed with Indanthren® Olive Green HB Colloisol (manufactured by DyStar) vat dye, in exhaustion process, with a bath ratio of 1:30. The dye concentration was 3%, and Na-hydrosulphite (Na2S2O4) was used as a reducing agent. The colouristic analyses were performed based on spectrophotometric measurement and results interpretation according to CIELAB system. The evaluation of primary tactile properties was performed which shown the increase of smoothness and softness after scouring and dyeing. Also, wash fastness as well as light fastness tests shown satisfactory fastness properties.
