objectives

i. Initial experiments are more focused on finding a simple, durable and economical surface modification method to apply Nano-clay onto polyester.

ii. The study is extended to develop a method to treat Nano-clay on cotton considering simplicity, economy, moisture management functionality, durability and controllability of the treatment method with minimum alterations to fabric’s desirable physical and mechanical properties.

iii. The study is designed to investigate the effects of the selected method on morphological, durable, physical and mechanical properties of polyester fabrics.

iv. The study was designed to statistically evaluate the physical and mechanical properties of researched nano-clay cotton fabrics with the intension of identifying a simple, yet durable and economical approach to apply silver nanoparticles on polyester fabrics with minimum alterations to fabric’s physical and mechanical properties.

overview

Polyester is a manmade fabric which has a greater demand in the clothing industry due to its characteristics such as improved wrinkle resistance, durability and high color retention. However, these synthetic fabrics inherits undesirable properties to the wearer, such as low moisture gain, high flammability and also the fibers have a tendency to accumulate static electricity. Thus, it has been identified the requirement for surface modifications of polyester to improve hydrophilicity, thermal properties, and permeability. There have been numerous research papers and patents published in this area and a considerable amount of research work is happening to improve the properties of polyester fabrics towards giving a comfortable fabric to the wearer. Recent studies are mainly focused on applying nanomaterials on polyester fabrics during manufacturing and finishing processes. Clay nanoparticles as a textile coating have gained much attention currently in the literature to bring new changes in textile finishing, such as flame retardant property.Clay is known to have a very good cooling and detoxification effect.

In this study, Montmorillonite clay nanoparticles will be coated on polyester fabrics with the intension of increasing hydrophilic properties of the fabric. Thus, a comfortable naturally detoxicated fabric can be achieved.

Finally, a statistical evaluation of the physical and mechanical properties of researched nano-clay polyester fabrics with the intension of identifying a simple, yet durable and economical approach to apply nano-clay on polyester fabrics with minimum alterations to fabric’s physical and mechanical properties will be done.
