Ironing is the use of an iron, usually heated, to remove wrinkles and unwanted creases from fabric. [1] 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 ...
The Power-Heat-Set process, formerly known as Suessen process, was developed in the beginning of the 1970s and was the first continuous heat setting system worldwide. The process itself was revolutionary in that it was the first system not operated with saturated steam and pressure, but with a superheated steam/airmix at atmospheric pressure.

The bonding settings for the most established metals are following (for 200 mm wafers): [1] Aluminium (Al) bonding temperature can be from 400 to 450 °C with an applied force above 70 kN for 20 to 45 min Gold (Au) bonding temperature is between 260 and 450 °C with an applied force above 40 kN for 20 to 45 min Copper (Cu)
The original Cricut machine has cutting mats of 150 mm × 300 mm (6 in × 12 in), the larger Cricut Explore allows mats of 300 mm × 300 mm, and 300 mm × 610 mm (12 in × 12 in, and 12 in × 24 in). The largest machine will produce letters from a 13 to 597 mm (0.5 to 23.5 in) high.
Thermosetting plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high-temperature applications up to the decomposition temperature since they keep their shape as strong covalent bonds between polymer chains cannot be broken easily. The higher ...
The required temperature varies both in absolute terms and in terms of the melting point of the base metal. Examples: Iron oxide becomes metallic iron at roughly 1250 °C (2282 °F or 1523 K), almost 300 degrees below iron's melting point of 1538 °C (2800 °F or 1811 K). [5]
A temperature interval of one degree Celsius is the same magnitude as one kelvin. The magnitude of the kelvin was redefined in 2019 in relation to the physical property underlying thermodynamic temperature: the kinetic energy of atomic free particle motion. The revision fixed the Boltzmann constant at exactly 1.380 649 × 10 −23 joules per ...
