Nylon: The chemical composition is polyamide fiber, which contains amide groups (CONH) in its molecular structure, exhibiting high abrasion resistance and good elasticity. Nylon is made from petrochemical products through polymerization reactions and is a fiber completely obtained through chemical synthesis.
There are significant differences between nylon and polyester in terms of chemical structure, physical properties, applications, and comfort.
Chemical structure and source
Nylon: The chemical composition is polyamide fiber, which contains amide groups (CONH) in its molecular structure, offering high abrasion resistance and good elasticity. Nylon is made from petrochemical products through polymerization, and is a fiber completely obtained through chemical synthesis.
Polyester: The chemical composition is polyethylene terephthalate (PET), which contains ester groups (COO) in its molecular structure, providing strong wrinkle resistance and abrasion resistance. Polyester is also synthesized from petrochemical products and is one of the common synthetic fibers.
Physical property comparison
Abrasion resistance: Nylon has excellent abrasion resistance and is considered one of the strongest in terms of abrasion resistance among all fiber materials, commonly used for making mountaineering clothing, sports shoes, and other garments that require high strength and durability. Although polyester's abrasion resistance is slightly inferior to nylon, it is still very good and widely used in everyday clothing and home goods.
Moisture absorption: Nylon has good moisture absorption, making it more comfortable to wear, especially in situations of heavy sweating, as it can better absorb moisture and reduce stickiness. Polyester has poor moisture absorption, essentially does not absorb water, which can lead to a feeling of stuffiness when sweating.
Elasticity: Nylon has very good elasticity, suitable for use in sportswear, swimwear, and other garments that require high elasticity. Polyester also has decent elasticity, but is not as ideal as nylon in high-elasticity applications.
Wrinkle resistance and stiffness: Polyester has excellent wrinkle resistance and stiffness, making the fabric less prone to wrinkling. Nylon's wrinkle resistance is relatively poor and can easily wrinkle after being under pressure for a long time.
Heat resistance and light resistance
Nylon: Has poor resistance to high temperatures, easily deforms and loses strength, and prolonged exposure to sunlight may cause the fibers to gradually become brittle and fade.
Polyester: Has good heat resistance and light resistance, can withstand higher temperatures without easily deforming, suitable for outdoor applications such as making tents and outdoor clothing.
Applications and comfort
Nylon: Due to its good moisture absorption and softness, it is more comfortable to wear, suitable for making sportswear, swimwear, etc. However, due to its poor breathability, it is prone to static electricity, and care should be taken regarding washing and maintenance conditions.
Polyester: Has good breathability and moisture-wicking properties, strong acid and alkali resistance, and UV resistance. Polyester fabrics have poor moisture absorption, leading to a feeling of stuffiness when worn, but they dry easily and do not easily deform, making them suitable for making outerwear and garments that require good washability.
