“…Thus, this rough surface led to more physical loosening of the microstructure of the fabric. Furthermore, X-ray diffraction measurements [ 11 , 31 ] also showed that the crystallinity of polyester fabrics was reduced by DBD plasma treatment. Dave et al [ 9 ] used the FTIR spectrum to show the amorphization of polyester fabrics by DBD plasma treatment.…”

“…During etching reaction, weight loss of the substrate occurs, and the topmost layer of the substrate is stripped off [ 16 ]. Moreover, the microstructure of polyester fiber has also been changed, and under the effect of DBD plasma, the fiber crystallinity has been reduced [ 9 , 11 , 31 ]. As a result, the fibrous structure can become looser and more porous.…”

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.
