Polyester is a generalized term for any fabric or textile, which is made using polyester yarns or fibres. Its a very durable fabric and is a popular fabric in the fashion industry, as it is resistant to shrining and stretching. It is also resistant to wrinkling and abrasions. The fibres are easily dyed. It retains its shape very well. Polyester fabric is easy to look after and it can be washed and dried at home. It is such a popular choice for apparel because polyester fibres are thermoplastic, or heat-sensitive. This means that fabrics, which are 100% polyester, can be given permanent pleats and decorative shapes and patterns can be laser-cut into them. They are also highly stain-resistant, so great for cleaning.
