Application scenarios
Where modacrylic fabric is used · In-service performance
Modacrylic is a modified acrylic copolymer with inherent flame resistance built directly into the molecular chain. When exposed to heat or electric arc, it self-extinguishes instantly without melting or dripping — it chars smoothly, eliminating the hazard of molten polymer sticking to the wearer's skin.
Hand feel and dyeability make modacrylic the premier choice for next-to-skin protective garments. It dyes easily into fluorescent hi-vis yellow and orange (EN ISO 20471), and blends with natural combed cotton to ensure all-day comfort for electrical utility, railway, and chemical plant operators.
Who makes it
Who makes the fabric
Our textile manufacturing roots go back to 1972 and the company was established in Shantou, Guangdong in 2002. The modacrylic in this cloth is spun and converted in a 30,000 m² integrated plant, so the fibre, the blend and the finished fabric come from one production chain rather than from a trader.
This page covers the modacrylic and modacrylic blend class as a whole, woven and knitted. Blend ratio, weight and shade are set with the order against the garment the cloth is going into, and where a programme needs a fabric-level test result we test the construction and report that lot.

Modacrylic woven twill & ripstop series (梭织改性腈纶系列)
Values are measured per production lot — ask our technical team for the batch data of the weight, weave and color route you plan to use.
Made to order
Specification options
Custom weight range spans 130 to 600 g/m² for woven constructions and 150 to 450 g/m² for knitted constructions. Antimony-free Protex-F fibre option available.
Modacrylic dyes easily and takes bright, saturated shades, which is a real advantage in this fibre: colour-coded and high-visibility workwear shades are practical where they are hard to reach in aramid. The shades our records name for the class are fluorescent yellow, white and navy. A full shade card is not held, so the colour chips are not printed here. Send the shade reference your programme uses and we will confirm it against the dyehouse, and tell us at the same time if the garment is a layered high-visibility build, because the high-visibility rating belongs to the assembled garment rather than to this cloth.
Standards and certification
This cloth is supplied on material-level data. The items below are the ones we can stand behind for the class today; the fabric-level routes are named in the note, and none of them is printed above as a held result.
- OEKO-TEX® STANDARD 100 Textiles tested for harmful substances. Our fabric certificate covers woven and knitted fabric made from the fibres in its certified list, modacrylic and its blends among them, at Product Class II. The certificate covers the certified fibre and form list rather than a single model.
- ISO 9001 Quality management system.
- REACH SVHC Declaration available on request for the exact article supplied.
The fabric-level routes for this class are EN ISO 14116:2015 and EN ISO 15025:2016; EN ISO 11612:2015, where a blend of this kind is typically recorded with an A1 or A2 code together with a B1 or C1 code when it is tested; EN ISO 11611:2015 only if the construction is tested for it, because welding performance cannot be inferred from the fibre; EN 1149-1 and EN 1149-5 for the versions that carry a conductive component; EN IEC 61482-1-1:2019 for an arc rating issued as material data; the ASTM material route of ASTM F1506-22 with ASTM D6413; and NFPA 2112 material testing. Each of those is arranged to the customer's requirement and reported for the production lot, and we hold no report for a construction of this class, so no grade is printed here. High visibility is not claimed for the cloth: EN ISO 20471 applies to an assembled garment with fluorescent background and retro-reflective material, and a flame-resistant high-visibility garment is a layered build that carries EN ISO 20471 together with EN ISO 11612. Standards written for a finished garment are assessed on the garment, and that assessment and its certification belong to the garment maker who builds on our material data. Test reports and certificate copies are available from our sales team on request.
Frequently asked questions
What is modacrylic fabric, and why blend it with cotton or viscose?
Modacrylic is a modified acrylic: acrylonitrile copolymerised with halogen-bearing monomers, which is what makes the fibre inherently flame resistant. It is blended with cotton or with FR viscose to get the comfort and the hand that a garment worn against the skin needs, while keeping the flame resistance in the fibre. The trade is that performance follows the blend ratio and the weight, so the figures for a construction come from testing that construction.
Does the fabric melt or drip?
No. Modacrylic chars and shrinks away from the flame instead of melting, so there is no molten polymer to stick to skin — the failure mode that makes a melting fibre dangerous in a garment worn against the body. Its limiting oxygen index is 27–34 against the 21% oxygen in ordinary air, which is why it self-extinguishes once the ignition source is removed. Its continuous working temperature is around 150–180 °C.
Which blend ratios and weights can you supply?
The constructions our records name are a 60% modacrylic / 40% FR viscose plain weave at 175 g/m², and a modacrylic / cotton interlock knit at 240 g/m², plus a modacrylic / cotton antistatic knit. Tell us the weight the garment needs and the fibre or restricted-substance constraint it works under, and we will confirm the blend and the construction against it.
What is the antimony-free option, and when should it be specified?
Some modacrylic fibres are produced with antimony as part of the flame-retardant chemistry, and antimony is restricted in several apparel programmes. Our antimony-free fibre exists for exactly that reason, so specify it when your programme screens for restricted substances or when the buyer asks for the substance declaration before approving the cloth. Where that matters, tell us at enquiry stage rather than at order stage.
Can this fabric be used for a high-visibility flame-retardant garment?
The cloth can go into such a garment, but high visibility is not a property of the cloth and we do not claim it as one. EN ISO 20471 applies to an assembled garment with a fluorescent background material and retro-reflective elements, and a flame-resistant high-visibility garment is a layered build that carries EN ISO 20471 together with EN ISO 11612. The assembly and its assessment belong to the garment maker; we supply the material data the build starts from.
Does the fabric hold a protective-clothing certification?
No, and we do not present it as if it did. What we supply is material-level data: composition, weight, construction and the fibre properties of the lot. The standards that apply to this class are applied by testing the fabric and reporting its codes, and the certification of a finished garment belongs to the garment maker who builds on that data. Where your approval file needs a standard-referenced result on the cloth, we arrange the testing to your requirement and issue the report for the lot.
