Nylon fibre is a synthetic fibre widely used in the production of many products as well as clothing. Petroleum and coal by products form the basic raw materials used for the production of premium quality nylon. These basic raw materials combine to produce Hexamethylene diamine and Acidic acid that forms a nylon salt which is spun into Nylon fibres.
General Properties of Nylon Fibre:
The length of the textile is controlled and can be produced in filament or staple form.
Nylon can be produced to be any desired fineness.
Nylon has a typical round shape but the cross sectional shape can be manipulated if so desired.
Nylon’s tenacity is very high and falls between 4.6 to 5.8 grams per denier.
Nylon is highly extensible and breaks at round about 30%, but the problem is its poor recovery after extension. For this reason, it is not used as sewing thread for garments.
Nylon displays excellent resilient properties and does not crease easily therefor it is widely used for pile fabric production of velvet and carpets.
Nylon fibre shows good frictional resistance. Due to its strength and exceptional frictional resistance properties it is widely used for rope.
The moisture regaining of nylon fibre varies between 4.2 to 5.0 percent. Nylon fibre does not absorb water easily. For this reason, nylon fabrics can be dried easily and is used for the production of raincoats and umbrellas.
End use of Nylon textiles:
1. Nylon is a high strength fibre. It is used for making fishing nets, ropes, parachutes and type cords.
2. It is used for making fabrics in the textile industry.
3. Crinkled nylon fibres are used for making elastic hosiery.
4. Nylon is widely used as plastic for making machine parts.
5. It is blended with wool to increase the strength.
