NYLON 6/6 Usage And Synthesis
DescriptionNylon 6,6 was first developed in 1935 by W.H. Carothers at DuPont and patented in 1938 for use as a textile fiber. It was originally given the name Fiber #66. The fibers are known to be strong, tough, and elastic. Importantly, as opposed to traditional fibers such as cotton, wool, and rayon, nylon fibers are glossy. They are extruded through a spinneret with a circular or trilobal cross section shape. Nylon 6,6 fibers can be used individually, i.e., as monofilaments, for brushes, surgical sutures, tennis strings, and fishing lines. Nylon 6,6 fibers are used for clothing, carpets, tire cords, conveyor belts, and brushes. Nylon 6,6 exhibits excellent dyeability and are twice as durable as Cotton (see Canvasetc.com). Nylon is sometimes coated with plastic, such as vinyl, to produce thin, lightweight waterproof fabrics.
Chemical Propertieswhite pellets, powder or fibre
UsesNylon 6/6 can be used as nanofibers for the fabrication of support materials for osmosis membranes. It can also be used in the formation of the nanofibrous membranes as separators in lithium-ion batteries.
DefinitionNylon-6,6 is a type of polyamide and is made of two monomers each containing 6 carbon atoms, hexamethylenediamine, and adipic acid. It is used to Fibers for textiles, brushes and sutures cable sheathing and tubing and bearings, cams, gears and casings for tools and appliances.
PreparationNylon 6/6 is synthesized by polycondensation of hexamethylenediamine and adipic acid with the removal of water.
Nylon 6/6 synthesis
General DescriptionNylon 6/6 is a thermoplastic material with good mechanical properties like elastic modulus (~21 MPa) and peak stress (~6.5 MPa). It also has good thermal stability and flexibility that makes it useful in the packaging of food items.
