Acrylic fiber has excellent light resistance and weather resistance, and is the best among common textile fibers. Exposed outdoors for one year, its intensity only decreases by 5%, and its resistance to sunlight is also one time greater than that of wool and 10 times greater than that of cotton. Therefore, acrylic fiber is most suitable for outdoor use. Acrylic fiber has good heat resistance and ironing temperature is 130-140 ℃. It is not moldy and not afraid of moths, but has poor wear resistance and dimensional stability. The relative density of nylon is small.
