# Microplastic Textile Rules and Natural Fiber for Apparel Brands > Microplastic textile rules restrict intentionally added particles; wash-off fiber is the next fight. Here's what natural fiber changes for apparel brands — and what it does not. *Published 2026-08-25 · tags: microplastic shedding, apparel brands* --- Microplastic textile rules are not one law, and they are not a license to print "compliant nylon-free" on a hangtag. The European Union already restricts *intentionally added* synthetic polymer microparticles. Wash-off fiber from nylon and polyester activewear is a different problem — unintentional microplastic shedding — and that is the stream brands get asked about by retailers, NGOs, and customers. Natural fiber does not shed plastic. That is the product fact. It is not, by itself, a legal opinion. [Imperium Fiber](/) makes a hemp-lyocell yarn for wellness athletic wear, swimwear, and intimates so the garment closest to skin is a [nylon alternative](/learn/natural-alternative-to-nylon-for-athletic-wear) that never starts as petroleum filament. This page is for product and sustainability teams who need the rules, the gap, and a spec they can defend. More of that brief lives in the [Journal](/learn). ## What Microplastic Textile Rules Mean for Apparel Brands Start with the distinction, or you will over-claim. [Commission Regulation (EU) 2023/2055](https://single-market-economy.ec.europa.eu/sectors/chemicals/reach/restrictions/commission-regulation-eu-20232055-restriction-microplastics-intentionally-added-products_en) restricts synthetic polymer microparticles on their own or intentionally added to mixtures. It began applying on 17 October 2023. Articles — a finished pair of leggings as a sewn garment — sit outside that restriction's core "intentionally added to mixtures" logic. Glitter, certain loose microparticles, and defined industrial uses are in a different bucket, with derogations and transition periods. That is why a counsel memo and a marketing page should not say the same sentence. Microplastic textile rules in force today are mostly about *added* particles. The political and retail pressure on apparel is about *shed* particles: the [microplastics](https://oceanservice.noaa.gov/facts/microplastics.html) that leave synthetic clothes in the wash and enter water. The [EPA](https://www.epa.gov/trash-free-waters) tracks that debris pathway as a trash-and-water problem, not as a REACH annex. Brands that sell into the EU, the UK, and US states are being asked both questions. Answer them separately. ## How Microplastic Shedding Became a Natural Fiber Issue Once you split "added" from "shed," natural fiber has a clear job. It does not put plastic microfibers into the drum. Filters on washing machines, wastewater plants, and downstream clean-up still matter for the synthetic installed base. They do not make nylon a natural fiber. Microplastic shedding is the reason a hemp-lyocell athletic line is a different product, not a different spin on the same polymer. ### Intentionally Added Particles vs Microplastic Shedding Intentionally added microparticles are a formulation choice: glitter, some encapsulated actives, loose synthetic polymer powders. Microplastic shedding is wear-and-wash: fragments that leave a filament that was never "added" as a particle. [IUCN](https://www.iucn.org/resources/issues-brief/marine-plastic-pollution) treats marine plastic as a materials problem, not only a littering problem. Apparel teams mix the two in decks because both use the word microplastic. Microplastic textile rules will keep using that word for both. Your BOM should not. ### EU Microplastic Textile Rules in Force Today The EU text to know by name is 2023/2055. Read the Commission page before you reuse a consultant slide. Natural, biodegradable, or water-soluble materials that are not regarded as microplastics sit outside the definition — which is why "biodegradable nylon" claims deserve a lawyer, and why plant-based cellulosic and bast fibers are a cleaner story. Unintentional releases from synthetic textiles remain on a separate EU policy track. Do not tell a retailer that 2023/2055 already banned polyester tights. Tell them you removed the plastic filament so shed is not plastic. ### Machine Filters and Other Microplastic Regulations France's AGEC anti-waste law pushed new washing machines toward microfiber-capture solutions from 2025. That is a machine rule, not a fiber rule. It still changes the apparel brief: European buyers now treat laundry-shed as a regulated environmental issue, not a niche NGO talking point. Other microplastic regulations will keep arriving as reporting duties, filters, and design-for-environment criteria. A brand that already specs natural fiber is not waiting for the next annex to start the work. ## How Natural Fiber Changes the Microplastic Shedding Conversation Natural fiber lets you say something true in a line review: this garment does not shed plastic microfibers, and it can biodegrade at end of life instead of fragmenting into persistent plastic. That sentence survives a technical challenge. "This SKU is compliant with all microplastic textile rules worldwide" does not. Use the first. Send the second to counsel. ### A Nylon Alternative That Does Not Shed Plastic A [hemp-lyocell nylon alternative](/learn/replacing-nylon-fabric-with-hemp-lyocell-same-great-strength-no-microplastics) with a small elastane fraction is built for stretch and recovery in leggings, bras, and shorts — the categories that wash often and sit on skin. Plant-based yarn is the shed decision. Elastane is the stretch decision; keep the fraction small and disclose it. For the fiber menu behind that blend, use the [hemp vs bamboo vs lyocell](/learn/hemp-vs-bamboo-vs-lyocell-activewear) comparison and the [hemp-lyocell spec guide](/learn/ultimate-guide-to-hemp-lyocell-blends-uses-and-benefits). ### What Natural Fiber Does Not Automatically Solve Natural fiber does not erase dyes, finishes, or elastane. It does not replace a PFAS water-repellent with magic. If the brief is forever chemicals, that is a [PFAS-free, pesticide-free performance fabric](/learn/pfas-free-pesticide-free-performance-fabric) conversation, not a REACH glitter conversation. It does not make a trail shell out of next-to-skin jersey. And it does not let you skip mill testing for recovery, colorfastness, and pilling. Microplastic textile rules reward honesty about scope. So does a wear trial. ### How Brands Spec Natural Fiber Against Microplastic Textile Rules Write two columns on the tech pack. Column one: intentionally added microparticles — none in the yarn, none in the finish, no plastic glitter. Column two: microplastic shedding — fiber content is hemp-lyocell (plus disclosed elastane), not nylon or polyester. Point retailers at fiber content, the [Journal](/learn), and [Imperium Fiber](/) for yarn. Ask for 20–35% hemp and 16s–30s Ne, then knit-down. Legal sign-off stays with your counsel.
