Lupus is an autoimmune disease. This means that the body's natural defense system (immune system) attacks healthy tissues instead of attacking only things like bacteria and viruses. This causes inflammation. Although some people with lupus have only mild symptoms, the disease is lifelong and can become severe.
Heat Settings for Fabrics. Use these basic iron temperature setting guidelines for your fabrics: acetate, 290 F; acrylic or nylon, 275 F; cotton, 400 F; linen, 445 F; polyester, silk or wool, 300 F; rayon, 375 F; triacetate, 390 F. For blended fabrics, use the lowest temperature recommended for the fibers in the blend.
The ratio of the cotton polyester blend ranges from 65 percent cotton and 35 percent polyester to a 50-to-50 blend. Blends with more polyester are less tolerant of heat from an iron; if your blend is a 65 percent cotton and 35 percent polyester blend, for example, then it can tolerate more heat than a 50-to-50 blend.
