1: nylon price is about 1 times higher than polyester
2: Nylon is softer and softer than polyester
3: Wear resistance is almost the same
4: Nylon has a little elasticity. Polyester is not weak.
5: Nylon dyeing is more difficult than polyester dyeing
Polyester fabric 
(1) Mechanical properties The breaking strength is high, the elongation is large; the initial modulus is high; the elastic recovery is good; the fabric is stiff, the wear resistance is good, and the dimensional stability is good.
(2) poor hygroscopic staining
W = 0.4%; normal temperature dyeing cannot be used. Easy to get static electricity, poor stain resistance
(3) Thermal properties have a high melting point of 255-265 ° C; good heat resistance and thermal stability
(4) Optical properties are good in light resistance, second only to acrylic
(5) Acid resistance is not resistant to strong alkali, not mildew
(6) Density: 1.38 g/cm3
Nylon (nylon)
(1) Mechanical properties The breaking strength, buckling strength is high, and the elongation is large; the initial modulus is low, the fracture work is large; the elasticity is good, the wear resistance is good, and the conformality and stiffness of the fabric are poor.
(2) hygroscopic dyeability W=4.5%, better than polyester
(3) Thermal properties: poor heat resistance; safe use temperature: less than 93 ° C (nylon 6), less than 130 ° C (nylon 66); melting point: 215 ° C (nylon 6), 250 ° C (nylon 66)
(4) poor light resistance
(5) alkali resistance and acid resistance
(6) Small density: 1.14g/cm3
Nylon is generally more elastic! The dyeing temperature is 100 degrees! It is dyed with neutral or acid dyes. The height-to-high ratio polyester is worse, but his strength is better, and the anti-pilling is good! The color of the smoke burned with fire is white. The polyester burned a black smoke, and the black ash followed. The dyeing temperature is 130 degrees (high temperature and high pressure), and the hot melt method is generally baked below 200 degrees! The main characteristics of polyester are stable, and a small amount of polyester in general clothes can help wrinkle and plasticity.
The main difference between fabric made of polyester and fabric made of nylon is:
