    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).

  4. 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.

    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 ...

  7. 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.

  8. Thermoplastic - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic

    It is also known as poly and is obtained by the addition polymerisation of ethylene. It may be of low density or high density depending upon the process used in its manufacturing. It is resistant to moisture and most of the chemicals. It is flexible at room temperature (and low temperature) and can be heat sealed.
