Dylon International is a British brand of textile dyes and other household chemicals. It was founded in 1946 by the Mayborn Group. [ 1 ] The Mayborn Group sold Dylon International to European homecare company Spotless Group in 2008.
Acid Chloride Preparative Route for Nylon-6,10, which is often used in the nylon rope trick. The nylon rope trick is a scientific demonstration that illustrates some of the fundamental chemical principles of step-growth polymerization and provides students and other observers with a hands-on demonstration of the preparation of a synthetic polymer.
Nylon is a family of synthetic polymers with amide backbones, usually linking aliphatic or semi-aromatic groups. Nylons are white or colorless [1] [2] and soft; some are silk-like. [3] They are thermoplastic, which means that they can be melt-processed into fibers, films, and diverse shapes.
In a reactive dye, a chromophore (an atom or group whose presence is responsible for the colour of a compound) contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing.
Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6 , are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid , which give nylon 66 its name. [ 1 ]
Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide. Unlike most other nylons , nylon 6 is not a condensation polymer , but instead is formed by ring-opening polymerization ; this makes it a special case in the comparison between condensation and addition polymers .
Zytel is a trademark owned by Celanese and used to make different high-strength, abrasion, and impact-resistant thermoplastic polyamide formulations, in the family of material more commonly known as nylon.
Almost all adiponitrile is hydrogenated to hexane-1,6-diamine for the production of nylon: [7] NC(CH 2 ) 4 CN + 4 H 2 → H 2 N(CH 2 ) 6 NH 2 Like other nitriles, adiponitrile is susceptible to hydrolysis; however, the resulting adipic acid is less expensively prepared via other routes.
