Question #48686
5 characteristics of man made fibres and 5 characteristics of artificial fibres
Expert's answer
Man-made fibres are fibres in which either the basic chemical units have been formed by chemical synthesis followed by fibre formation or the polymers from natural sources have been dissolved and regenerated after passage through a spinneret to form fibres. These fibre came to success when the researchers obtained a product by condensation of molecules presenting two reactive aminic groups with molecules characterised by two carboxylic reactive groups.
Most synthetic fibers are polymer-based, and are produced by a process known as spinning. This process involves extrusion of a polymeric liquid through fine holes known as spinnerets. After the liquid has been spun, the resulting fibers are oriented by stretching or drawing. This increases the polymeric chain orientation and degree of crystallinity, and has the effect of increasing the modulus and tensile strength of the fibers. Fiber manufacture is classified according to the type of spinning that the polymer liquid undergoes: this may be melt spinning, dry spinning, or wet spinning.
