•The low moisture regain helps in quick transport of moisture required in special applications like babies ever-dry nappies.
• The polypropylene fibre poses lower thermal conductivity than other fibres. This nature of polypropylene allows users to use it for applications as thermal wear.
The main demerits of polypropylene fibres are given below:
• The polypropylene fibre poses poor ultra-violet and thermal stability .
• It is flammable which melts and burns like wax.
• It has poor resilience in comparison to polyester and Nylon,
