What are the main differences between polyester fabrics and nylon fabrics?

1: The price of nylon is about 1 times higher than that of polyester

2: Nylon is smoother and softer than polyester

3: The wear resistance is almost the same

4: Nylon has a little elasticity. Polyester has no weakness

5: Nylon dyeing is more difficult than polyester dyeing

polyester

(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=%; normal 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: g/cm3

Nylon (Nylon)

(1) Mechanical properties; high breaking strength and buckling strength, long elongation; low initial modulus, high breaking work; good elasticity, good wear resistance, and poor shape retention and stiffness of the fabric.

(2) Hygroscopic dyeability; W=%, 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: g/cm3

Nylon generally has better elasticity! The dyeing temperature is 100 degrees on it! Dye with neutral or acid dyes. The high resistance is worse than that of polyester, but its strength is better and anti-pilling is good! The color of the smoke burned by the fire turned 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 characteristics of polyester are better stability. Generally, adding a small amount of polyester to clothes can help to resist wrinkle and plasticity. The disadvantage is that it is easy to generate static electricity and pilling. However, these shortcomings of the improved polyester have been improved.
