NYLON
—
It is the most widely used synthetic fiber, due to its high strength.
Matt or glossy thread, very resistant to abrasion, moths and bacteria.
Characteristics:
· Tenacity: 4 to 7 gr./denier.
· Density: 1.14
· Heat reaction: Form hard balls, smell of celery.
· Sensitive to: Mineral acids, formic, acetic, concentrated and certain phenols.
· Resists: Strong alkalis (Ammonia, soda).
· Resistance to friction: Good.
POLIÉSTER
—
It is the fiber that best preserves all its characteristics under any circumstance and environment.
Matte or glossy thread of great softness, resistant to light, moths and bacteria.
Characteristics:
· Tenacity: 4 to 7 gr./denier.
· Density: 1.38
· Heat reaction: Flammable melts at 260 ° C, forms hard balls, aromatic odor.
· Sensitive to: Strong alkalis, hot concentrated acids and phenols.
· Resists: Mineral acids, organic oxidizers and alkalis.
· Resistance to friction: Maximum.
POLIPROPILENO
—
It is the lightest synthetic fiber, although polypropylene
It has low resistance to sunlight, approximately 900 hours,
This inconvenience can be remedied in part by mixing the raw material
stabilizer additives. Likewise and upon request, it can be manufactured in any color.
Different materials are obtained through different manufacturing procedures:
- Polypropylene Monofilament
- Multifilament Polypropylene
- Polipropileno Fibre-Film (Rafia)
Characteristics:
· Density: 0.91
· Heat reaction: Softens at 145 ° C and melts at 165 ° C
· Sensitive to: Some industrial solvents
· Resists: Acids, alkalis and oils.
