Dope-dyed para-aramid fibers

Extreme collision and iterative upgrade. Delicate and tough fiber bears the exploration and innovation of fiber practitioners.Benefited from the cross of fiber boundary,breakthrough of limit, perfect fusion with the extreme, and the collisions to gain endless possibilities and

amazing charm, each strand shows exquisite skills and ingenuity to realizie hard core protection. Fiber hasbecome more and more lighter, stronger, tougher and resistant to high temperature,

facilitating its use in anti-cutting clothing, shoematerials, fire-fightingclothing, flight clothing,military equipment, urban light box cloth, fluedust removal, wind power blades, aerospace and

other fields. Fiber shows its best accompanying in extreme details and high value in extreme environments.

EXTREME UPGRADE

SPECIAL FIBERFORSHOES ANLOTHING

Shoes and clothing are made from special fibers,foreseeing the future with excellent performance.The high cut resistance of carbon fiber and the

high toughness of ultra-high molecular weight polyethylene fiber are perfectly combined to create cut-resistant ultra-high molecular weight

polyethylene fiber products which can effectively shield us from accidental scratches at work,maximizing protection and comfort.PBT/PA6

skin-core composite monofilament, combining the strength and stiffness of polyester with the abrasion resistance and moisture absorption of

nylon, can provide excellent support for shoe upper proprietary materials. Fine denier polyimide fibers, in-situ coloring of para-aramid pioneered

for apparel applications, bringing disruptive experiences to special wear scenarios.para-aramid.

Dope-dyed para-aramid fibers

Recommendation Reasons

While maintaining the original excellent properties of aramid fibers, it has high strength, flame retardant and temperature-resistance property, and can be customized with bright and rich colors. It has a very broad market demand and application prospect in the fields of military and high-end digital product protective cases and so on.

Processing Technology

The color paste is added to the para-aramid fiber spinning dope, and then fed through the spinneret, extruded into the coagulation bath for spinning. Finally, the produced fibers are washed and dried.

Q: Do you know the excellent properties and the widespread application of dope-dyed para-aramid fibers?

A: With the natural color of golden yellow, para-aramid fiber has high

strength, high modulus, outstanding heat resistance and good stability. Lt has a shrinkage rate of 0 at 150℃ and can maintain high strength at high temperature. For example, 65% of the original strength can be maintained at 2600.The development of dope-dyed para-aramid fiber can meet the needs of personalization and special fields. For example, it can be made into woven fabrics and combined with resin to produce 3C protective cases and sports equipment, and can be made into yarns to produce combat uniforms, flight clothings and firefighter uniforms.
