Producer
Teijin Aramid BV
Dutch subsidiary of Teijin Ltd. (Japan; TSE: 3401); the world's second-largest meta-aramid producer (~20% global revenue share) under the Teijinconex brand. Meta-aramid production is in Japan (Iwakuni, Yamaguchi Prefecture — Teijinconex classic) and Thailand (Ayutthaya — Teijinconex neo, dyeable variant, 2,200 t/yr). The Netherlands facilities (Emmen, Delfzijl, Arnhem) produce para-aramid Twaron — NOT meta-aramid. Key distinction: when the Netherlands is listed as a meta-aramid producer, the corporate HQ is Dutch but actual meta-aramid fibers are made in Japan and Thailand. Arnhem pulp facility closing 2025. Teijinconex serves firefighter PPE, electrical insulation, and protective clothing globally. Teijinconex neo (Thailand) is dyeable to customer colors without additional chemical treatment, addressing a key limitation of Nomex.

Teijin Aramid – Arnhem Pulp Plant (Netherlands, closing 2025) →
NLGelderland
Located in Kleefse Waard industrial zone, Arnhem, Gelderland. Produces specialty Twaron pulp grades and recycles Twaron products. Announced for closure in 2025 as part of a 15% workforce reduction — attributed to elevated Dutch energy/labor costs and price competition from Asian (primarily Chinese) producers. Affects specialty pulp grades, not the standard yarn used in optical fiber cable. Closure of Arnhem marks a significant step in the retreat of European non-fiber aramid processing from the Netherlands.
Teijin Aramid – Ayutthaya Plant (Thailand) →
THPhra Nakhon Si Ayutthaya
Bang Pa-in Industrial Estate, Ayutthaya Province, Thailand. Produces Teijinconex neo — a dyeable meta-aramid fiber variant that can be colored to customer specifications without additional chemical treatment. Construction December 2013 – August 2015; investment ~JPY 4.5 billion (~$36M); 70 employees; 22,985 m² site. Capacity ~2,200 metric tons/year. Teijinconex neo targets heat-resistant protective apparel; dye-ability is a key differentiation over Nomex (which can only be dyed by specialized treatment). REACH compliant. Teijin aimed for JPY 20B in global protective apparel sales by 2020, leveraging this Thailand facility as cost-effective Asian production.
Teijin Aramid – Delfzijl Monomer Plant (Netherlands) →
NLGroningen Province
Upstream monomer and polymer production for Twaron at Delfzijl, Groningen Province. Feeds the Emmen spinning plant. Critical upstream chokepoint — Delfzijl supplies the para-phenylene diamine (PPD) and terephthaloyl chloride (TCl) monomer feedstocks that are polymerized into poly-paraphenylene terephthalamide (PPTA) resin, which is then dry-jet wet spun into Twaron filaments at Emmen.
Teijin Aramid – Emmen Spinning Plant (Netherlands) →
NLDrenthe Province
Main Twaron production facility at 1e Bokslootweg 17, Emmen, Drenthe — described as the world's largest aramid factory. Operates 24/7 shifts; three sub-facilities on site: spinning, converting/after-treatment, and Endumax tape. Capacity ~36,500 metric tons/year (spinning). Expanded by 25%+ through 2022 investment program (announced December 2017). Produces Twaron yarn directly used in optical fiber cable strength members (ADSS, FTTH, premises cables). Continues full operations despite Arnhem site closure.
Teijin Aramid – Iwakuni Plant (Yamaguchi, Japan) →
JPYamaguchi Prefecture
Teijin's primary meta-aramid production facility for Teijinconex fiber; Iwakuni, Yamaguchi Prefecture. This is the site where Teijinconex (classic meta-aramid, poly(m-phenylene isophthalamide) / MPIA) is manufactured. Also houses a Solution Development center. Critical geographic note: when literature cites the Netherlands as Teijin's meta-aramid production location, this is incorrect — the Dutch facilities (Emmen, Delfzijl, Arnhem) produce para-aramid Twaron. Teijinconex meta-aramid is made in Japan. Teijin Aramid BV is the Dutch corporate entity but the meta-aramid fiber itself comes from Japan and Thailand.

Did you know2015
Teijin's Teijinconex neo meta-aramid (produced at Ayutthaya, Thailand) is the world's only commercially available dyeable meta-aramid fiber — it can be permanently dyed to any color without additional chemical processing, unlike Nomex which requires specialized dye processes. This sounds like a minor technical detail until you realize what it means operationally: Teijinconex neo allows fire departments, militaries, and industrial companies to put thermal-protective clothing in any color — color-coded by hazard level, role, or rank — while maintaining full REACH compliance. Teijin built a factory in Thailand to make a fiber that matches uniforms. In a market dominated by institutional Nomex loyalty, this is one of the few legitimate performance differentiators that challenges Arclin's market position.
Textile World ↗Incident2025
In 2025, Teijin Aramid announced it would close its Arnhem production site (specialty pulp grades and recycling) and cut 15% of its global workforce. The stated reason: elevated Dutch energy and labor costs combined with intensifying price competition from Asian — primarily Chinese — para-aramid producers. This is the first significant European aramid production site closure since Kevlar was invented in 1965. It reflects a broader pattern: as Chinese producers (Sinochem, Yantai Tayho, Sinopec) scale up, the cost structure of Dutch and UK aramid production comes under pressure — even for a product with no good substitute.
