Another polyester, "PTT" (Polytrimethylene terephthalate) , also called Sorona or 3GT (Dupont)or Corterra (Shell), is a variant of PET. Lurgi Zimmer PTT was first patented in 1941, but it was not produced until the 1990s, when Shell Chemicals developed the low-cost method of producing high-quality 1,3 propanediol (PDO), the starting raw material for PTT Corterra Polymers.
• Acrylic
Acrylic is a synthetic material first created by the Dupont Corporation in 1941 but has gone through various changes since it was first introduced. In the past Acrylic used to fuzz or pill easily, this happened when the fibres degraded over time and short strands broke away with contact or friction. Over the years Acrylics have been developed to alleviate some of these problems although the issues have not been completely removed. Acrylic is fairly difficult to dye but is colourfast, washable and has the feel and appearance of wool making it an ideal rug fabric.
