Difference between PP non-woven fabric and polyester nonwoven fabric

1, different production materials

PP non-woven fabric: nonwoven fabric production fiber is polypropylene, which is a synthetic fiber obtained by propylene.

Polyester nonwoven fabric: Non-woven fabric production fiber is a polyester fiber, and the synthetic fibers obtained by agglomerated with an organic diomerate and a diol.

2, different density

PP non-woven fabric: The density is only 0.91 g / cm3, which is the lightest variety in common chemical fibers.

Polyester nonwoven fabric: Polyester is completely unmoid, the density is 1.333 g / cm3.

3, different light resistance

PP non-woven fabric: poor light tolerance, no sunlight, easy to aging.

Polyester nonwoven fabric: good light resistance, the strength is only 60% after the sun is irradiated with 600 h.

4, different thermal performance

PP non-woven fabric: poor thermal stability, no ironing.

Polyester nonwoven fabric: hot resistance, the melting point is about 255 ° C, and the shape is stable under a wide range of final use conditions.

5, alkali-resistant

PP non-woven fabric: polypropylene has better chemical resistance, except for concentrated caustic sodium, polypropylene resistance is good.

Polyester nonwoven fabric: Polyester to resist alkali resistance, at normal temperature and concentrated alkali, high temperature and dilute alkali can make fiber damage, only in low temperature, dilute alkaline or weak alkali is more stable.
