Nylon is the name of a family of synthetic polymers that are commonly used to make a variety of different types of apparel and consumer goods. Unlike other organic or semi-synthetic fibers, nylon fibers are entirely synthetic, which means that they have no basis in organic material. Recycled nylon is produced from post-industrial waste or from discarded nylon-based products. In addition to their environmental friendliness, the recycled nylon fibers are both strong, light and durable. Nylon fabrics have low resistance to sunlight and tend to weaken and may become discolored on direct exposure to it. For drying purposes, it is better to avoid sunlight and dry it in the shade. Nylon is also heat sensitive, and thus high temperatures may cause it to shrink, loosen, or discolor. Thus, exposing the fabric to high temperatures should be avoided.Usually, dirt does not cling to nylon fabrics, thus making it easy to clean it. However, in cases of severe dirt and soil removal, a pretreatment would be required. That is, prepare a thick paste of detergent and water and apply it on the soiled areas using a soft brush. Then, soak it for about 10-15 minutes in detergent water. You can then proceed with the normal washing procedure.
