The difference between polyester fabric and nylon fabric Polyester fabric

(1) Mechanical properties High breaking strength, high elongation; high initial modulus; good elastic recovery; stiff fabric, good wear resistance and good dimensional stability.
(2) Poor hygroscopic dyeing
W=0.4%; room temperature dyeing cannot be used. Easy to generate static electricity, poor stain resistance
(3) Thermal properties High melting point 255-265°C; good heat resistance and thermal stability
(4) Optical properties Good light resistance, second only to acrylic fibers
(5) acid and alkali resistance, no mildew or moth
(6) Density: 1.38 g/cm3



Nylon fabric
(1) Mechanical properties High breaking strength and buckling strength, long elongation; low initial modulus, large work at break; good elasticity, good abrasion resistance, and poor shape retention and stiffness of the fabric.
(2) Moisture absorption and dyeing property W=4.5%, better than polyester
(3) Thermal properties Poor heat resistance; safe use temperature: lower than 93°C (nylon 6), lower than 130°C (nylon 66); melting point: 215°C (nylon 6), 250°C (nylon 66)
(4) Poor light resistance
(5) Alkali-resistant and acid-resistant
(6) Smaller density: 1.14g/cm3


Nylon generally has better elasticity! The dyeing temperature is 100 degrees! Dye with neutral or acid dyes. High resistance is worse than polyester, but his strength is better, and anti-pilling is good! The color of the smoke burned with fire turns white. The polyester burned with black smoke, and black ash floated up. The dyeing temperature is 130 degrees (high temperature and high pressure), and the hot-melt method is generally baked below 200 degrees! The main features of polyester are better in stability. Generally, adding a small amount of polyester to clothes can help wrinkle resistance and plasticity.
