Descrizione principale (Inglese)

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.
