Ironing a shirt. 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 ...
Wrinkle-resistant or permanent press or durable press is a finishing method for textiles that avoids creases and wrinkles and provides a better appearance for the articles. . Most cellulosic fabrics and blends of cellulosic-rich fabrics tend to crease or wri
The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.
A Madiba shirt is a loose-fitting silk shirt, usually adorned in a bright and colourful print. It became known in the 1990s, when Nelson Mandela—then elected President of South Africa—added the item to his regular attire. Mandela popularised this type of shirt, elevating the seemingly casual garment to formal situations.
One application of thermal ionization is thermal ionization mass spectrometry (TIMS). In thermal ionization mass spectrometry, a chemically purified material is placed onto a filament which is then heated to high temperatures to cause some of the material to be ionized as it is thermally desorbed (boiled off) the hot filament.
