- Para-Aramid
vs. Meta-Aramid: Para-Aramid (Kevlar style) is for high
strength/impact; Meta-Aramid (Nomex style) is for high heat/flame
resistance. - UV
Exposure: Aramids are sensitive to UV; they should be jacketed or
coated if used in prolonged direct sunlight to prevent strength loss. - Ballistic
Protection: Multi-layer Para-Aramid fabrics are the core component in
bullet and fragment-resistant vests due to their energy absorption. - Cut
Resistance: Para-Aramids offer incredible cut resistance, making them
standard for glass-handling gloves and chainsaw chaps. - Fire-Retardant
Workwear: Meta-Aramid fibers do not melt or drip when exposed to
flame, providing a life-saving barrier for flash-fire protection. - Dyeing
Aramids: Meta-Aramids are typically solution-dyed during production
because the fiber is extremely difficult to dye after it is spun. - Moisture
Regain: Aramids can absorb moisture, which can slightly affect their
weight and electrical properties, though not their fire resistance. - Decomposition
Temp: Para-Aramids don’t melt; they begin to decompose or char at
approximately 450°C (840°F). - Hybrid
Composites: Mixing Basalt and Aramid creates a composite that has the
stiffness of basalt and the impact toughness of aramid. - Chemical
Resistance: Meta-Aramids have excellent resistance to most fuels,
lubricants, and cleaning solvents used in aerospace and racing. - Maintenance:
Aramid garments should be washed at low temps and kept away from bleach,
which destroys the molecular bonds of the fiber. - Expansion
Joints: Hybrid Aramid/Glass textiles are the preferred choice for
industrial expansion joints that require both flexibility and heat
resistance. - Lightweight
Shielding: Aramids are much lighter than fiberglass for the same
strength, allowing for weight savings in aircraft heat shields. - High
Friction: Technical fibers like Aramid are used in brake linings and
clutch plates because they maintain integrity under high friction heat. - Aramid
Webbing: Yes, it is used for heavy lifting slings in “hot
work” environments where nylon or polyester would melt instantly. - Electrical
Insulation: Meta-Aramids provide high dielectric strength and are
widely used as paper insulation in motors and transformers. - Pilling:
Proper finishing and yarn twisting techniques are used in our technical
textiles to minimize pilling in high-wear areas. - Resin
Compatibility: Aramids require specific “sizing” or surface
treatments to ensure a strong bond with epoxy resins in composite
manufacturing. - Shelf
Life: Aramids have an almost indefinite shelf life if stored in a
cool, dry, dark place away from UV light. - Why
Hybrids? Hybrids (e.g., Aramid/Glass) give you the best of both
worlds: the high-temp stability of glass with the durability and
flex-life of aramid.If you like to read more, go to https://texbay.us/product-category/textile-goods/technical-fiber-products/kevlar-wovens/
