Chemical Fiber Names: Scientific Names and Trade Names
Chemical fiber names often confuse buyers, mills, and new sales staff because one fiber can carry several names. A fiber may have a scientific name, a common domestic name, a staple fiber name, a filament name, and several trade names used in different countries. Therefore, before we quote a yarn or prepare a sample, our team first checks what the name really means.
In daily yarn work, we do not treat a fiber name as a small wording issue. It affects quotation sheets, sample labels, fiber content, test reports, certification files, and bulk order communication. For example, polyester may appear as Dacron, Terylene, Tetoron, or Lavsan in older documents. Nylon 6 may also appear as polyamide 6, PA6, Capron, Perlon, or Amilan. These names may point to the same fiber family, but they should not replace the correct generic name in formal textile documents.
From our factory view, clear chemical fiber names reduce mistakes before sampling. In our sample room, we often place an old buyer specification beside yarn cones, lab dip records, and small knitted swatches. Then we check the fiber name, yarn form, count, spinning method, color route, and final application. This simple step saves time, especially when the yarn will go into socks, close-to-skin knitwear, home textiles, medical or hygiene textiles, industrial fabrics, or automotive interior materials.
How Chemical Fiber Names Are Formed
Most chemical fiber names come from chemical composition or processing method. Polyester gets its name from the ester group in its polymer structure. Polyamide gets its name from the amide group in the polymer. Viscose gets its name from the viscose process used to make regenerated cellulose fiber.
However, factories and markets do not always use the same naming habit. In Chinese textile documents, short chemical fibers often use names ending with “lun,” while filament yarns often use names ending with “si.” For overseas buyers, clearer wording works better. We usually write polyester staple yarn, polyester filament yarn, nylon 6 filament, viscose staple yarn, acetate filament, or acrylic staple yarn.
Meanwhile, trade names follow another logic. A trade name may come from a manufacturer, a country, or a long-used market habit. These names help when teams read old specifications. Even so, the generic fiber name should come first in quotation, labeling, testing, and certification work.
Main Synthetic Chemical Fiber Names and Trade Names
The table below lists the main synthetic chemical fibers that buyers often see in old specifications, quotation sheets, and yarn documents. We keep the scientific name first, then compare the common Chinese names and trade names used in different markets.
| Scientific / Generic Name | Common Chinese Staple Name | Common Chinese Filament Name | Trade Names Often Seen | Factory Note |
|---|---|---|---|---|
| Polyamide 6 fiber | Jinlun 6 | Jinlun 6 filament | Nylon 6, Capron, Perlon, Amilan | Confirm PA6 before sampling. It differs from PA66 in heat behavior, price, and some performance details. |
| Polyamide 66 fiber | Jinlun 66 | Jinlun 66 filament | Nylon 66 | Many teams choose PA66 for stronger abrasion or higher heat requirements, but the final fabric still needs testing. |
| Polyester fiber | Terylene / polyester staple | Polyester filament | Dacron, Terylene, Tetoron, Lavsan | Polyester appears widely in socks, knitwear, home textiles, industrial textiles, and recycled yarn programs. |
| Polyvinyl alcohol fiber | Vinylon | Vinylon filament | Vinylon, Vinalon | Some technical textile projects still use this fiber, so buyers should confirm end use and processing limits early. |
| Polyacrylonitrile fiber | Acrylic | Acrylic filament | Orlon, Acrilan, Courtelle, Cashmilon | Acrylic often appears in warm yarn, wool-like yarn, winter knitwear, and home textile yarns. |
| Polyvinyl chloride fiber | Chlorofiber | Chlorofiber filament | Teviron, Rhovyl, Movil | This fiber appears less often in ordinary apparel. Heat behavior and market regulations need attention. |
| Polypropylene fiber | Polypropylene staple | Polypropylene filament | Meraklon, Herculon, Pylen | Polypropylene has low weight and hydrophobic behavior, so hygiene, nonwoven, and industrial routes often use it. |
Main Regenerated Chemical Fiber Names and Trade Names
Regenerated chemical fibers can be even easier to mix up, because some markets still use older names such as rayon, artificial silk, artificial cotton, or polynosic. These fibers start from natural cellulose or other natural polymer sources, but chemical processing turns them into usable textile fibers.
| Scientific / Generic Name | Staple Fiber Name | Filament Name | Commercial Names Often Seen | Factory Note |
|---|---|---|---|---|
| Viscose fiber | Viscose staple fiber | Viscose filament | Rayon, artificial cotton, artificial wool, artificial silk | Viscose gives soft hand feel and moisture absorption. Fabric testing should still check wet strength, shrinkage, and pilling. |
| Cuprammonium fiber | Cupro staple fiber | Cupro filament | Cupro, cuprammonium rayon | Cupro gives a smooth and silky touch. Before sampling, confirm availability, price, and dyeing route. |
| Acetate fiber | Acetate staple fiber | Acetate filament | Acetate silk, cellulose acetate | Acetate suits fabrics that need drape or luster. Heat, washing, and care conditions matter. |
| High wet modulus viscose fiber | High wet modulus viscose | Usually not treated as ordinary viscose filament | Polynosic, Fuqiang fiber | This fiber improves wet strength compared with ordinary viscose, but buyers still need fabric-level washing checks. |
Scientific Names and Trade Names Do Different Jobs
A scientific or generic name tells us what the fiber is. A trade name tells us how a market or company has sold that fiber. Because they serve different purposes, our team keeps them separate.
For example, Dacron, Terylene, Tetoron, and Lavsan may all refer to polyester fiber. Orlon, Acrilan, Courtelle, and Cashmilon may refer to acrylic fiber. Nylon 6 and nylon 66 both belong to the polyamide family, but they do not behave exactly the same in production. Therefore, a buyer should not replace one name with another without confirmation.
In quotation sheets, we prefer a clear format: generic name first, trade name second if needed. For example, “polyester fiber, also known in some older specifications as Dacron or Terylene” gives more clarity than using only the trade name. This wording helps the buyer, yarn supplier, knitting mill, testing lab, and certification team work from the same material understanding.
Staple Fiber and Filament Names
The original Chinese naming logic also separates short fiber and filament. This detail matters in yarn production. Staple fiber goes through spinning after the fiber has been cut into shorter lengths. Filament continues as a long fiber and may go through texturing, twisting, or other processing before weaving or knitting.
As a result, polyester staple yarn and polyester filament yarn create different fabric surfaces. Nylon staple yarn and nylon filament also run differently on machines. Viscose staple yarn gives a different fabric feel from viscose filament. The fiber family may stay the same, but the yarn form changes the final result.
In our factory discussion, we ask two questions at the same time: what fiber name and what yarn form? On an 18G sock machine, this difference can show up quickly. A staple yarn may create more hairiness and a softer surface, while a filament yarn may give clearer loops and a smoother face. That is why the name must match the intended yarn construction.
Fiber Names Do Not Prove Fabric Function
A chemical fiber name only identifies the fiber family. It does not prove the final fabric function. Polyester does not automatically mean quick dry. Nylon does not automatically mean every fabric will pass abrasion targets. Viscose does not automatically guarantee stable shrinkage after washing. Acrylic does not automatically solve pilling.
For functional yarns, this point becomes even more important. Antibacterial function may come from a natural fiber structure, a natural substance, an internal additive, or a surface finishing process. Each route has a different wash durability risk. Therefore, the function source and the test method need confirmation before bulk production.
For antibacterial programs, teams often discuss ISO 20743 or AATCC 100. Our antibacterial yarn testing ISO 20743 and AATCC 100 page explains how test method choice affects function claims. The fiber name, function claim, and test report should support each other.
Yarn Testing and Fabric Testing Are Not the Same
Yarn testing checks the yarn before fabric production. It can cover fiber content, count, twist, strength, evenness, color, cone condition, and sometimes basic function data. This step helps the buyer decide whether the yarn matches the requested specification.
Fabric testing checks the result after knitting, dyeing, finishing, washing, and garment processing. Therefore, it gives a more realistic answer for market use. In our sample room, we may approve a yarn cone for trial, but we still wait for knitted fabric and wash test feedback before recommending bulk.
For socks, we check knitting stability, stretch, hand feel, and washing result. For close-to-skin knitwear, we pay more attention to softness, pilling, color, and comfort. For home textiles, shrinkage and touch after drying matter more. For medical, hygiene, industrial, and automotive textile programs, documents and test conditions become stricter.
Compliance Starts With the Correct Fiber Name
For export orders, fiber names should follow recognized textile standards. ISO 2076 lists generic names for chemical fibers, including polyester, polyamide, acrylic, viscose, acetate, and polypropylene. The official ISO 2076:2021 page gives the standard details.
For the U.S. market, the FTC explains textile labeling requirements, including generic fiber names and fiber percentages. The FTC textile labeling guidance gives useful direction for covered textile products.
Certification files also need accurate naming. OEKO-TEX STANDARD 100 focuses on harmful-substance testing, while Textile Exchange standards such as GRS support recycled-content claims. However, these documents do not replace fiber identification. For official references, buyers can check OEKO-TEX STANDARD 100 and Textile Exchange standards.
A Simple Rule for Chemical Fiber Names
Use the generic chemical fiber name in formal documents. Keep trade names only as supporting references. If an old file says Dacron, Terylene, Tetoron, or Lavsan, confirm polyester. If it says Orlon or Cashmilon, confirm acrylic. If it says rayon, confirm whether the buyer means viscose, cupro, acetate, or another regenerated fiber.
For recycled yarn, antibacterial yarn, cooling yarn, thermal yarn, or other functional yarns, write the function beside the correct fiber name. Do not use the function word to replace fiber composition. For example, recycled polyester cotton yarn still needs clear composition, recycled-content documents, and batch traceability. Our GRS recycled polyester cotton yarn page shows how composition, process, and document support stay connected.
Chemical fiber names may look like basic textile knowledge, but they affect real yarn decisions. Clear naming helps buyers compare materials correctly, reduce sample mistakes, choose the right test method, and keep bulk communication stable. When our team confirms the fiber name, yarn form, test requirement, and application together, the project has a lower risk of wrong labels, failed tests, rework, claims, or delivery delay.
