High tenacity polyester fabric can be machine washed. Polyester fabric has high strength, with an impact resistance 4 times higher than nylon and 20 times higher than viscose fibers. The surface of polyester is smooth, with tightly arranged internal molecules and a lack of hydrophilic structure between molecules, resulting in low moisture regain and poor moisture absorption performance. Its wet strength is basically the same as its dry strength. Therefore, washing polyester clothes with a washing machine will not shrink or deform.
However, polyester is a synthetic fiber that is different from natural fibers such as cotton and wool. It is more wear-resistant, washable, and resistant to fading. However, it is still very important to choose the correct washing method according to the instructions on the washing label, avoiding the use of overheated water, strong rubbing, and improper bleaching agents. At the same time, it is also necessary to avoid mixing with easily dyed clothes to avoid dyeing.
Overall, machine washing polyester clothing is feasible, but attention should be paid to the washing method to avoid damage to the clothing.
