Textile fiber science has a very wide range of applications. Technological textiles will have the opportunity to expand their market reach and reach through innovative products. The market for innovative technical textiles is being affected by the development of new goods and innovative finishes. Functional finishes provide value addition, allowing product lines to be strengthened and new markets to be explored. Polyester fiber (PET) is a highly significant textile fiber that finds extensive application in apparel, home furnishings, and certain industrial domains because of its exceptional mechanical stability, high strength, and affordability. However, a number of issues with polyester fabric, including its hydrophobic nature, pilling issue, and difficulty in dyeing, reduce its comfort attributes. Numerous attempts have been made to improve and acquire desired properties to polyester fibers, such as the use of low-temperature atmospheric plasma to increase its wetability and dyeability.
