The difference between polyester material and nylon material

Polyester, also known as polyester fiber. The characteristics are good gas permeability and moisture wicking, as well as strong acid and alkali resistance and UV resistance.


Nylon, also known as polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good deformation resistance and aging resistance; the disadvantage is that the hand feel is hard.

Polyamide fiber

The difference between polyester material and nylon material:

Polyester (polyester fiber)

1. Mechanical properties have high breaking strength

The elongation is large; the initial mold height is high; the elastic recovery is good, the fabric is stiff, the wear resistance is good, and the dimensional stability is good.

2. Optical properties

Good light fastness, second only to nylon

3. Thermal properties

Melting height 255-265 ° C; good heat resistance and thermal stability

4. Acid resistance is not resistant to alkali, not mildew

5. Hygroscopic dyeing is poor

W = 0.4%; normal temperature dyeing cannot be used. Easy to get static electricity, poor stain resistance

6. Density: 138g/cm3


Mechanical properties

The breaking strength and buckling strength are higher and the elongation is larger; the initial lifting mold is lower and the breaking work is larger; the elasticity is good, the wear resistance is good, and the shape retaining property and the straightness of the fabric are poor.

2. Poor light resistance

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. Alkali resistance and acid resistance

5. Hygroscopic dyeability W = 4.5%, better than polyester

6. Small density: 1.14 g/cm3
