Influence of Functional Finishes and Polyester Type on Comfort Properties of Active Sportswear
Abstract
Sweat generation and loss of metabolic energy are more in active sports compare to other activity of human being. There is a need to design a fabric which gives comfort in these conditions. The moisture vapor transmission, air permeability, wicking of moisture and drying behavior by fabric influences the comfort of clothing. The comfort behavior of fabric is improved by various technologies like change in fabric structure; change in fiber composition or by chemical treatment. In the present study, the comfort characteristics of weft knitted fabrics were investigated after chemical treatments using different levels of concentration of four different finishes. The weft-knitted jersey fabric is produced using three different types of polyester fibers. Moisture management properties of the fabric and supporting factors like thickness, porosity, contact angle, drying behavior, water vapor permeability and vertical wicking is studied to evaluate the overall comfort behavior of fabric after finishing. It is found that all the parameters specified in moisture management test are significantly improved by moisture management finish, while soil release and antimicrobial finish have a lesser impact. The ultraviolet finish significantly influences to the moisture management properties of micro-polyester fabric only. The micro polyester fabric is exhibit better moisture management than texturized polyester and polyester spandex blended fabric. This is due to more capillary channels available to transport the liquid quickly from a top surface to bottom surface. The water vapor permeability, vertical wicking, drying behavior and air permeability are significantly improved with the application of moisture management finish and higher in micro-polyester fabric compare to other types of polyester fabric. The effect of the laundering cycle is also studied and found that after ten laundering cycle, there is an increase in all studied comfort properties. Thus, fabrics made of micro polyester and treated with moisture management finish may be used to have excellent comfort during rigorous physical activities.Downloads
