Properties of fibers
Each polymer and fibre has its own inherent characteristics such as length, diameter, moisture regain, elongation, chemical reaction, which in turn, affect the properties of yarn an finally the fabrics. Therefore, one can see a visible differance between fabrics, such as cotton and wool or wool and silk, or linen and polyester.
Primery properties refer to the properties essential for a polymer to be regarded as a suitable material for making fibers and secondary properties are the ones desired by the consumer as they improve the wearing and maintenance characteristics of the fabric. Additional properties also affect the fiber performance. The properties are being discussed with the respect to fibers and one must remember that the properties of the fabric depend on not only the fiber properties but also on other manufacturing processes, such as yarn and fabric construction, finishing and the other processes involved in the production of the fabric.
