(can be positive, when we want to have a sharp crease) Combustible: a fiber that burns easily/catches on fire easily. All cellulosic fibers will behave the same way. Wool will go out by itself if caught on fire. Not all of cellulosic fibers are natural/manufactured they are both. Milk is the only manufactured protein based fiber. You need to know the characteristics of the fibers. The characteristics of the fibers will determine the characteristics of your fabrics. Always need to be concerned about the price.
