Don’t synthetics eliminate problems with shrinkage and wrinkles?
Again, it depends. Rayon, for example, absorbs humidity and shrinks under hot, humid conditions. Windows hung with rayon curtains will have shorter curtains in the hot, humid summer and the same curtains will hang longer in dryer, cooler winters. Some synthetics, like acetate, do resist wrinkles, but so do some fabrics made from natural fibers, like wool and silk. There is a vast difference among synthetic fibers, just as in the naturals. Wool is a very different fiber than silk. So, too, rayon differs from acrylic and olefin.
