The treatment of polyester fabric in alkali medium is a common chemical modification process for producing a fabric with desirable qualities such as soft cloth, fabric regain, water absorbency, and fabric pilling with draping. However, if the optimization of the chemical treatment was not maintained, there could be serious decrease in mechanical strength of polyester fabrics. In this study, surface modification via low-temperature plasma application ( lt;50 0C) were used as an alternative to chemical modification of polyester fabrics with alkaline treatment and the effects of both chemical and surface modification on mechanical and chemical properties of polyester fabrics were investigated. Parameters of chemical modification such as exposure time and concentration of alkali were varied while different exposure time was used in plasma application as a surface modification treatment. Performance tests such as mechanical strength, loss of weight and hydrophilicity of polyester fabrics were tested after each modification. Scanning electron microscope (SEM) micrographs were characterized as well. According to the test results; loss of weight of polyester fabrics after chemical modification was more than occurred right after surface modification. Advantages of surface modification on polyester fabrics were clearly seen in this study, especially when compared to high concentration alkali treatment. It was also considered that these functionalized polyester fabrics could be used as an alternative platform for 3DP (three-dimentional printing) applications before deposition of the polymers. |
