Ultra fine fiber polyester and nylon are two common synthetic fibers, which have significant differences in chemical structure, physical properties, and applications. The following are the main differences between the two:
Chemical structure
Polyester (polyester fiber): Its chemical name is polyethylene terephthalate (pet), and its molecular structure contains ester groups (coo), which have good stability and chemical corrosion resistance.
Nylon: Chemical name for polyamide fiber, with amide groups (conh) in its molecular chain, it has high strength and wear resistance.
Physical property
Wear resistance: Nylon has better wear resistance than polyester, especially in high-strength applications such as hiking clothes and sports shoes.
Moisture absorption: Nylon has good moisture absorption and is suitable for making close fitting clothing, while polyester hardly absorbs water and has poor breathability.
Elasticity: Nylon has better elasticity recovery than polyester, making it suitable for making clothing that requires high elasticity, such as swimwear and sportswear.
Wrinkle resistance: Polyester has good wrinkle resistance and is not easily deformed after washing, while nylon is prone to leaving wrinkles.
Thermal properties
Heat resistance: Polyester has good heat and light resistance, suitable for high temperature environments, while nylon is more sensitive to high temperatures and sunlight, and is prone to deformation and fading.
Purpose
Polyester: Commonly used in daily clothing, household items, and industrial materials such as curtains, bed sheets, and ropes.
Nylon: Widely used in high-strength fields such as cables, fishing nets, and parachutes, as well as in the production of close fitting clothing such as underwear and socks.
Price
Price: The price of nylon is usually twice that of polyester, mainly due to its excellent performance and complex production process.
Through the above comparison, it can be seen that there are significant differences between ultrafine fiber polyester and nylon in multiple aspects. Users can choose the appropriate material polyester nylon according to their specific needs.
