Abstract
Polyester fabrics have taken the primary position in textiles applications all over the world, however they have main drawback such as low moisture regain, about only 0.4%. Due to the inherent hydrophobic nature of Polyester fibers, fabrics formed entirely from Polyester fibers exhibit relatively poor moisture absorption and release properties introduce an uncomfortable condition to the wearer. Although Polyesters are non-absorbent, the present study focuses on adding enhanced and durable hydrophobicity properties to Polyester fabrics. Over the past few decades the interest in plasma techniques attracted the interest of many researchers to explore the outstanding properties added to the materials after plasma treatment. Plasma modification of textiles represents great opportunity for improvement of older, energetically demanding, and slow and sometimes not very eco-friendly treatment technologies.In the current investigation, plasma treated yarn and fabric were produced by using Atmospheric non polymerization Plasma. A set up was developed to produce the proper conditions of plasma treatments. The plasma conditions were investigated to control the extent of plasma surface modification. The effect of non-polymerization plasma has been studied on the physical properties like wettability, water wicking, and tensile strength. In the present study, the hydrophobicity of fibrous material was increased using atmospheric plasma treatment. The role of various plasma process parameters, such as discharge intensity, exposure time, and between electrode distance, on the hydrophilic and surface properties of the yarn has been investigated. The changes in chemical and morphological characteristics of plasma treaded textile fibrous were also be studied using different techniques , such as wicking height, water absorption and SEM. The results show that atmospheric pressure plasma can impart desired functional properties and improve wetting ability and hydrophilicity.Moreover, Polyester fabric has been coated using a cellulose solvent of NaOH /urea/thiourea aqueous solution at 8/8/6.5 compositions following by applying two different methods for treatment. Aqueous NaOH/urea/thiourea solution as non-derivatizing solvent broke the intra- and inter-molecular hydrogen bonding of cellulose and prevented the approach toward each other of the cellulose molecules, leading to the salvation of cellulose which the hydrophilic properties imparted to these substrates. The effect of percentage of cellulose solution coating has been studied on some physical properties such as fabric wettability, water wicking, stiffness, and air permeability, as well as the method of application of the cellulose coating. The surface characterization of the coated Polyester fabric is performed using FTIR and SEM. The results relate to coated Polyester fabric demonstrated enhanced and durable hydrophobicity and rewetting properties due to hydrophilic properties imparted to these substrates.
