Understanding the characteristics of polypropylene and polyester is crucial when choosing synthetic fiber materials.
The following is the main performance comparison between the two:
Physical and mechanical properties
Initial modulus of elasticity: Polyester has a higher initial modulus, providing better rigidity and resistance to deformation; Polypropylene is relatively low and suitable for applications that require flexibility.
Wear resistance: Polypropylene has better wear resistance than polyester and is suitable for environments with frequent friction.
Breathability and moisture absorption
Polypropylene: It has poor breathability and moisture absorption, making it suitable for occasions that require lightweight and waterproof properties.
Polyester: Although it has good breathability and moisture absorption, it may not be ideal in applications that require good breathability.
Appearance and wearing comfort
Polypropylene: Fine denier polypropylene improves appearance and feel, making it suitable for making high-end clothing.
Polyester: Traditional polyester may have a rough appearance, but modern technology has improved its appearance and feel.
Application scenarios
Polypropylene: commonly used in the production of sportswear, outdoor equipment, etc., due to its lightweight and waterproof properties.
Polyester: widely used in clothing, home textiles, industrial materials and other fields due to its high strength and durability.
