   They are temperature-resistant up to 120 °C (248 °F). Bonded polyester sewing threads are tough, coated with abrasion resistance, rot proofing, and have exceptional tensile strength for lower temperatures but heavier-duty sewing operations. They are temperature-resistant up to 120 °C (248 °F).

3. Ironing - Wikipedia

   en.wikipedia.org/wiki/Ironing

   The heating is commonly done to a temperature of 180–220 °C (360–430 °F), depending on the fabric. [2] Ironing works by loosening the bonds between the long-chain polymer molecules in the fibres of the material. While the molecules are hot, the fibres are straightened by the weight of the iron, and they hold their new shape as they cool.

4. Finishing (textiles) - Wikipedia

   en.wikipedia.org/wiki/Finishing_(textiles)

   Textile finishing machinery, Red Bridge Mills, Ainsworth, 1983 In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or clothing.

5. Nonwoven fabric - Wikipedia

   Nonwoven geotextile bags are much more robust than woven bags of the same thickness. [1] Geocomposite drain consisting of needle-punched nonwoven filter and carrier geotextiles of polypropylene staple fibers each having a mass per area of 200 g/m². [1] Nonwoven geotextile containers (sand bags) are used for soil stabilizers and roadway ...

6. Step-growth polymerization - Wikipedia

   en.wikipedia.org/wiki/Step-growth_polymerization

   Polyester has high glass transition temperature T g and high melting point T m, good mechanical properties to about 175 °C, good resistance to solvent and chemicals. It can exist as fibers and films. The former is used in garments, felts, tire cords, etc.

7. Wet process engineering - Wikipedia

   The dyes are finely ground in the presence of a dispersing agent and sold as a paste, or spray-dried and sold as a powder. Their main use is to dye polyester but they can also be used to dye nylon, cellulose triacetate, and acrylic fibers. In some cases, a dyeing temperature of 130 °C is required, and a pressurized dyebath is used.

8. Polyester resin - Wikipedia

   en.wikipedia.org/wiki/Polyester_resin

   Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.

9. Heat deflection temperature - Wikipedia

   en.wikipedia.org/wiki/Heat_deflection_temperature

   The heat distortion temperature is determined by the following test procedure outlined in ASTM D648. The test specimen is loaded in three-point bending in the edgewise direction. The outer fiber stress used for testing is either 0.455 MPa or 1.82 MPa, and the temperature is increased at 2 °C/min until the specimen deflects 0.25 mm.
