“…Moreover, the consumed chemical amount was half of the maximum concentration without the LOI changing significantly. In work [ 21 ], an organophosphonate (OP), as the FR agent, was applied to the untreated and oxygen plasma-treated polyester fabric samples using the pad-dry-cure method. The results reveal that oxygen plasma treatment prior to finishing significantly increased the wettability of the polyester fibers, which directly resulted in increased concentration of the absorbed finishing agents.…”

“…This allows the plasma pretreated sample to have better FR properties than those of the control sample. Thus, works [ 4 , 19 , 20 , 21 ] have shown that the plasma pretreatment for polyester fabric improves the efficiency of the subsequent flame retardant treatment despite using different types of plasma and flame retardants. However, plasma pretreatment for PET fabric can also have undesirable effects.…”

“…The aforementioned studies (except study [ 12 ]) used undyed PET fabrics, as their purpose was to activate the PET fabric prior to dyeing or printing [ 9 , 11 , 13 ]. The works that applied the plasma to activate polyester fabrics before the FR treatment [ 4 , 19 , 20 , 21 ] also used undyed fabrics. Meanwhile, the functional finishing treatment for the fabric is usually performed after the dyeing step.…”

In the first part of the study, dyed polyester fabric was treated with a dielectric barrier discharge (DBD) plasma at 1 W/cm2 for 15, 30, 60 and 90 s. The wicking height, tensile strength and color of the control and plasma treated fabrics were measured. Results show that the fabric capillary increases with plasma treatment time up to 90 s. However, plasma treatment time longer than 60 s caused an obvious color change and decrease in tensile strength of fabric. Plasma contact time should be such that plasma can improve the hydrophilicity of the fabric and adversely affect the properties of the fabric as little as possible. Thus, the suitable plasma contact time should be less than 60 s. Based on these results, in the second part of the study, three different time levels (15, 20 and 30 s) were selected for plasma pretreatment of this fabric. The plasma-treated fabric was then padded with the flame retardant (FR) (CETAFLAM PDP 30), dried and finally cured at 190 °C for 120 s. The limited oxygen index (LOI) of FR fabrics and the vertical fire characteristics of FR fabric after being washed 5 times also were measured. Comparison of these results with those of FR fabrics without plasma pretreatment shows that plasma pretreatment improves the fabric’s flame retardancy and FR durability. Moreover, it also reduces the heat shrinkage of PET fabric due to high temperature curing. The scanning electron microscopy (SEM) images of the fabric after plasma treatment and FR treatment and the energy-dispersive spectroscopy (EDS) spectrum of the fabric are consistent with the above results.
