Today, the biggest contributor to the appeal of polyester is the discovery of microfibers. Microfibers give polyester the feel of silk and are rapidly becoming the choice of fabric. With an expensive tag to match, the cheap image of polyester seems to be on its way out. Here’s to hera...
The availability of polyisocyanates in 1952 led to the widespread use of polyester-isocyanate urethane systems. A few years later, polyether polyols in the form of poly tetramethylene ether glycol (PTMEG) were introduced in 1956 by DuPont. The next year, BASF and Dow Chemicals developed polyalkyle...
