H.P. fibres are the fibres which have which have high strength, temperature resistance, good flexibility, light weight, fine diameter & durability etc. Qualities are used mainly for technical textile purpose.

1. High Performance
FibreSayantan Raha (MFT)

2. DIFFERENCE BETWEEN GENERAL FIBRES AND
HIGH PERFORMANCE & TEMPERATURE
RESISTANT FIBRES:
1. General fibers can be used for human wearing clothing because, it gives
COMFORT to human body. High performance fibres does’t giving comfort
to body but it protects body from accident of bullet type material.
2. The use of cotton & other fibres do not have capability to used in
INDUSRIAL APPLICATIONS.
3. General fibres do not having enough TENSILE STRENGTH to handle high
load, thus H.P. fibres which have this property are used.
4. General fibres do not have HIGH ABBRASION RESISTANCE
power than High Performance fibres.

3. What are High Performance Fibres
• H.P. fibres are the fibres which have which have high strength, temperature
resistance, good flexibility, light weight, fine diameter & durability etc.
