Many outdoor textiles are made out of acrylic fibers. However, due to designer and customer demand for more flexible colors as well as commercial fire code and abrasion requirements, manufacturers have developed other polymer yarns to meet outdoor application demands.
The new polymer yarns include polyester and polypropylene fibers. These fibers have higher resistance to hydrolysis and ultraviolet exposure; thus, an increasing number of outdoor fabrics are made out of polyester and polypropylene.
