Tayho / Yantai Tayho High-Performance Aramid Fibers and Yarns

Engineering performance and molecular structure of Taparan 1100 Dtex para-aramid filament yarns

Taparan 1100 Dtex (nominal linear density 1100 decitex, equivalent to 1000 Denier, yarn structure 1100 Dtex / 667F) is manufactured from poly(p-phenylene terephthalamide) (PPTA).

Featuring fully extended, rigid rod-like polymer chains oriented along the fiber axis with dense intermolecular hydrogen bonding, Taparan achieves a tensile tenacity of 21 to 23 cN/dtex (tensile strength exceeding 3.0 GPa) and an initial Young modulus of 75 to 110 GPa.

With a material density of 1.44 g/cm3, Taparan delivers a specific strength 5 to 6 times superior to high-grade steel wire while offering an 80 percent weight reduction.

The filament maintains structural tenacity under continuous operating temperatures from -196 deg C to +204 deg C, exhibiting no melting point and decomposing only at temperatures above 500 deg C.

For elastomer reinforcement in automotive hoses and transmission belts, yarns are treated with specialized epoxy or resorcinol formaldehyde latex (RFL) adhesion finishes.

Applications in hydraulic rubber hoses, radial tires, and fiber optic cable strength members

In high-pressure hydraulic hoses and turbocharger air ducts, Taparan 1100 Dtex yarn serves as braided or spiraled textile reinforcement.

Unlike metallic wire braids, aramid yarn resists fatigue under pulsating pressure cycles, eliminates corrosion concerns, and reduces overall hose assembly weight by up to 40 percent.

In fiber optic telecommunication cables (ADSS and loose-tube designs), Taparan filaments provide dielectric longitudinal tensile reinforcement.

The non-conductive aramid strands prevent lightning damage and electromagnetic induction along high-voltage transmission corridors while safeguarding sensitive optical glass fibers against tensile strain during cable installation.

Thermal resilience and hot gas filtration behavior of Tametar meta-aramid fibers (PMIA)

Tametar poly(m-phenylene isophthalamide) (PMIA) fibers are engineered for industrial needle-punched nonwoven felts and filter bags operating in high-temperature baghouses across cement, asphalt, and metallurgical facilities.

Tametar provides continuous thermal endurance up to 204 deg C and survives short-term temperature excursions up to 240 deg C with a Limiting Oxygen Index (LOI) greater than 28 percent.

To ensure reliable filtration life under harsh gas conditions, operators must prevent acid dew-point condensation. When hot exhaust gases contain sulfur oxides (SOx) and moisture above 150 deg C, meta-aramid fibers can undergo hydrolytic degradation.

Tametar filter media are treated with fluoropolymer water-and-oil repellent finishes, singeing, and heat-setting calenders to capture submicron particulate matter (PM2.5) while ensuring smooth dust cake release during pulse-jet cleaning.

Asbestos replacement and thermal stability in friction materials using Taparan aramid pulp

Taparan highly fibrillated aramid pulp consists of short para-aramid core fibers branched with microscopic sub-micron fibrils.

With a specific surface area reaching 8 to 12 m2/g, Taparan pulp creates a three-dimensional mechanical network in friction mix matrices for automotive brake pads, heavy-duty clutch facings, and industrial gasket sheetings.

Incorporating 1.5 to 3.0 percent Taparan pulp by weight prevents component segregation during dry compounding and hot compression molding.

Under severe braking temperatures up to 450 deg C, Taparan maintains a stable coefficient of friction, mitigates thermal fade, and suppresses cast-iron rotor scoring, ensuring smooth, vibration-free deceleration.

Functional grades of Newstar polyurethane spandex elastane filaments (10D to 2680D)

Newstar spandex elastomeric filaments encompass an extensive denier range from 10D to 2680D.

Synthesized from PTMEG soft segments and MDI hard segments, Newstar delivers elastic recovery above 95 percent, rapid stretch rebound, and sustained flex fatigue resistance under cyclical mechanical deformation.

Specialty heat-resistant Newstar grades survive high-temperature disperse dyeing at 130 deg C while retaining over 80 percent tensile tenacity.

Chlorine-resistant variants prevent polymer degradation in active swimming pool environments, and narrow-tape hygiene grades ensure smooth continuous payoff on automated lines.

Tametar conductive anti-static fibers and Metastar electrical insulation papers

For personal protective apparel in hazardous ATEX zones across petrochemical refineries and powder handling mills, Tametar conductive fibers incorporate carbon conductive phases, providing stable volume resistivity around 10^4 Ohm cm at ambient temperature.

Blending 1 to 3 percent conductive Tametar fibers into spun protective fabrics continuously dissipates triboelectric charges to ground, eliminating incendiary spark risks.

Additionally, Metastar aramid insulating papers deliver dielectric strength up to 40 kV/mm under Class H and C thermal standards for traction locomotive transformers.

Technical guidelines for twisting and weaving Taparan para-aramid yarns

During winding, warping, and twisting operations with Taparan para-aramid continuous filaments, avoiding contact with sharp metallic guides is critical to preserve filament integrity.

Precision mirror-polished aluminum oxide or zirconia ceramic eyelets are recommended alongside continuous yarn tension control calibrated within 0.3 to 0.5 cN/dtex.

For weaving ballistic fabrics on rapier or air-jet looms, relative ambient humidity should be held at 55 to 65 percent at 20 to 24 deg C to suppress static buildup.

Automated multi-ply fabric cutting is carried out using carbide circular blades or ultra-high pressure waterjet systems to avoid thermal edge melting.
