Abstract/Hauptbeschreibung (Englisch)

This article presents the results of research on flame retardant treatment for dyed cotton fabric using two procedures (with and without pretreatment with DBD plasma). One bath pad-dry-cure method was used for the flame-retardant finishing. Pyrovatex CP new (PCN), Knittex FFRC (K-FFRC) were used as flame retardant and crosslinking agents. The research results show that, with the fire retardant solution including PCN 450/l and K-FFRC 107 g/l, and the curing temperature at 180°C for 150 seconds, dyed cotton fabric after fire retardant treatment will be durable flame-retardant fabric (LOI of the flame-retardant fabric ≥ 25% even after 5 washing cycles). However, if the dyed cotton fabric is pre-treated with DBD plasma with a power 2 of 1w/cm for 30 seconds, the curing time can be reduced to 120 seconds, the flame retardant treated fabric will be still a durable flame-retardant fabric. At these conditions, the colour of the dyed cotton fabric is not changed by plasma treatment. However, flame retardant treatment changes the colour of dyed cotton fabrics at a medium (2.0 ≤ DE CIELab≤3.5). Keywords.
