POLYESTER FIBRE

चित्र
PO LYESTER FIBER   Polyester is a synthetic fibre made from petroleum-based chemicals.  Its name is shortened to represent a synthetic man-made polymer and is commonly known as a PET (polyethylene terephthalate). Polyester has a long history, dating back to the early 1900s. However, it wasn’t until the 1950s that it became widely used in textiles It’s created by combining long chains of synthetic polymers to form a fibre that is typically used to make clothing, upholstery, and carpeting. In the 1970s’, polyester was marketed as a miracle fabric that was wearable for over 65 days straight without ironing whilst still looking presentable.   polyester is one of the most common fabrics in the world and has many great qualities. CHEMICAL STRUCTURE  MANUFACTURING PROCESS  The procedure of creating polyester filament begins with the reaction of ethylene glycol with dimethyl terephthalate at extensive heat. This composition results in a monomer.  Further ...

  POLYPROPYLENE  Polypropylene is produced by polymerization of propylene using a catalyst in solution, mass or gas phase. For the polymer, propylene monomer is polymerised to make polypropylene  Raw material is propylene  Benefits :  A cost-effective way to achieve high-strength concrete and other construction materials Is compatible with many processing techniques, which means there are many applications of polypropylene Offer great chemical resistance to a lot of common solvents Thanks to its mechanical properties it can get a good balance between stiffness and impact Is resistant to freeze-thaw weathering Has low moisture regain, making it a good choice even for humid environments. Manufacturing process :  Extrusion: L/D=30, compression ratio=1:3.5 Metering: one or more spinning gear pumps receives the molten polymer and sends it through the spinning pack to homogenize the product, feed the spinning pack at a constant rate, and prevent fluctuation due t...

                  SYNTHETIC FIBRES  1.Synthetic fibres are made from                     chemicals and petroleum-based                   compounds. Common types include           polyester, nylon, acrylic, and spandex. 2.Synthetic fabrics have become integral       to our daily lives. 3.They are derived from petroleum-based     chemicals, unlike natural fibres. 4.They can be engineered to produce              fabrics with desired properties. 5.Synthetic fabrics are generally cheaper       to produce than natural fabrics. 6.They are durable, wrinkle-resistant and        retain their shape well.
