Polyester Mesh Fabric Basic Knowledge

Released on May. 26, 2021

1. Polyester chemical name, temperature resistance, melting point

1) The chemical name of polyester is polyethylene terephthalate, and the English name is POLYESTER (PET)

2) The melting point of polyester monofilament is 236℃, under normal conditions it is heat-set under 200℃

3) PET polyester plastic has excellent mechanical properties. The hardness is large, the water absorption is small, and the dimensional stability is good. Good toughness, impact resistance and friction resistance. Operating temperature -100~120℃. The elongation rate is 1.8%-2.7%.

3. Product model identification

For example, 22504 "22" means that the warp density is 22 threads/cm, "50" means that the warp and weft thread diameter is 0.5mm, "4" means the number of weaving nets, and the 2-layer net is 4/4 weaving. 22503 is a one-layer semi-dry net with a 3/3 weaving method.

2050903 "20" means that the warp thread density is 20 threads/cm, "50" means that the warp thread diameter is 0.5mm, "90" means that the weft thread diameter is 0.9mm, and "3" means 1/2 weaving.

03902 "03" means that the warp thread density is 3 strands/cm, "90" means that the warp and weft thread diameter is 0.9mm, and "2" means 1/1 weaving.

 

4. Air permeability measurement unit conversion

1000 L/㎡S=(1000×3.6) m3 /㎡h

1000 CFM = (1000×16.66) m3 /㎡h

Generally, we now use the L/㎡S unit, and CFM is the international common air permeability measurement unit. When the product is used in the non-woven fabric industry, customers generally use m3/㎡h to express the air permeability unit.

 

5. Product application

1) Paper mills

2) Sludge dewatering

3) Power plant desulfurization

4) non-woven

5) MDF

6) Fruit and vegetable juice

7) washing

8) Cooling

9) Food drying, etc.
