Polypropylene fiber and nylon have obvious differences in many aspects. The following is a detailed point-by-point representation and summary of the differences between the two fibers:
Raw materials
Polypropylene fiber: Fiber made of polymers synthesized from polypropylene.
Nylon (polyamide fiber): Polyamide fiber synthesized from phthalic acid and p-phenylenediamine.
Physical and chemical properties
Polypropylene fiber:
The strength is close to nylon, and the wear resistance is second only to nylon.
It has a small specific gravity and is the smallest density among all synthetic fibers.
It almost does not absorb water, but has wicking ability.
It has good chemical stability and is resistant to acid and alkali corrosion.
It has poor light resistance and heat resistance, is easy to age, and is not resistant to ironing.
It has poor dyeability, but can be dyed with stock solution.
Nylon:
It has the best wear resistance among all kinds of fabrics, many times higher than similar products.
It has a better hygroscopicity among synthetic fiber fabrics.
It is a light fabric, second only to polypropylene and acrylic.
Excellent elasticity and elastic recovery, but easy to deform under small external force.
Poor heat resistance and light resistance, need to pay attention to washing and maintenance conditions.
Application areas
Polypropylene fiber:
Ropes, packaging materials, fishing nets, parachutes, etc.
Compounded with other fibers to process high-end carpets, etc.
Medical, sanitation, home and other fields, such as surgical gowns, sanitary napkins, curtains, etc.
Nylon:
Clothing, car seats, plastics, sports goods, etc.
Socks, scarves, clothing and toothbrush bristles, etc.
Features and advantages
Polypropylene fiber:
Lightweight, soft, antibacterial and UV-resistant.
Has good elasticity and durability.
Affordable.
Nylon:
Wear-resistant, heat-resistant and corrosion-resistant.
Has good elasticity and water absorption.
High strength, strong elongation and excellent elasticity.
Summary
Polypropylene fiber and nylon have significant differences in raw materials, physical and chemical properties, application areas, characteristics and advantages. Polypropylene fiber is widely used in the fields of medical treatment, hygiene, and home furnishing due to its light weight, softness, antibacterial and UV resistance, while nylon occupies an important position in the fields of clothing, car seats, and sporting goods due to its wear resistance, heat resistance, and corrosion resistance. When purchasing fiber products, you need to choose the appropriate material according to the actual situation.
