Wrinkle-free clothes

Do you like to wear shirts in the office, which you do not need to iron after washing, so called non-iron shirts? Unfortunately after a few washing cycles this property gets lost, they become wrinkled and need to iron them.

Everyone is short on time and ironing is a pain.To make cotton clothes wrinkle free it needs to be blended with other synthetic fibres like polyester. So in the early 1990s, textile companies began to apply finishing agents to fabrics to prevent or decrease wrinkles. These particular chemical agents act as catalysts that cross-link polymer chains in the cotton weaving, giving the material some elasticity and resilience. In short, this treatment makes clothes wrinkle-free.

Due to the increasing demand for 100%cotton fabrics, durable press finishes are being used on these clothes.Generally, cotton fibers are spun into yarn, woven into fabric, and then dyed, and the last part of the process is treating it with a 'cross-linking' resin. The applications of formaldehyde based reagents that are used to create these apparels are now creating ripples all across the globe backing up with concerns for human health and environment

Several problems have been associated with wrinkle-resistant finishes, such as attracting grease and oil stains, fabric degradation and environmental concerns. Most of the problems have been minimized but companies are constantly finding ways toimprove the properties.

Home care:
a) wash the material at lower temperature settings, low stress cycle, weaker detergents - to reduce loss of structure
b) find clothing with more polyester in it - to strengthen structures, or  
c) iron every now and then and making sure that the clothing cools in a dry, pressed state - to regain structures.
