Yarn and pattern prep before knit / weave
Lock the yarn line in the tech pack
Paste the Ne/Nm/Tex/Denier table from this tool into PO and sample approval. Copy PO line for supplier chat in one unit system — for folded yarn use the resultant count (÷ plies).
Match pattern density to yarn fineness
Fine yarn (high Ne/Nm) allows thinner lines and smaller motifs; heavy counts limit detail. Size repeats in the Generator against your yarn ticket — for filament, reference the Denier/dtex row.
Build seamless repeats before sampling
After yarn spec is clear, create seamless designs in AI Pattern Studio with the same palette. Spot-color count drives print cost — pair with the GSM converter when adding fabric weight to the PO.
Paste the conversion table and PO line from this tool into sample approval. For folded yarn use the resultant count (÷ plies) — wrong yarn count skews knit/weave scale in mockups.
Pick template and drape for yarn fineness
Fine yarn (high Ne/Nm) reads cleaner on light fabric templates with small motifs; heavy counts need wider repeats on tee/scarf mockups. Evaluate GSM and yarn ticket together in Mockup Studio.
Open the yarn PO after buyer approval
Buyer sign-off should follow scale/rotate steps in the mockup guide. After approval, move the yarn line from this converter into purchasing; audit credits/cost on Account History.
Paste the PO / chat line from this tool into sample approval notes. Plied yarn (20/2 Ne) and filament Denier/dtex values should stay on the same PO — wrong yarn count skews repeat density and print resolution estimates.
Match yarn count to source pixels and repeat density
Finer yarn (higher Ne/Nm) needs tighter repeats; knit patterns with filament Denier/dtex may require upscaling when source px is low. Save source width × height alongside your 300+ DPI target line before upscaling.
Move approved pattern art into Upscale Studio
After the yarn ticket is clear before PO signature, run the same knit/digital print designs through Upscale Studio to 300+ DPI at final print size. Max output side is 16,384 px — read the Upscale quality guide for the SSIM ≥ 0.85 threshold; audit upscale credits/cost on Account History.
Cotton Ne uses Tex ≈ 590.5 / Ne. Wool, linen and specialty systems can differ — for filament yarns prefer Denier / dtex / Tex. Folded yarn assumes equal plies.

Many yarn pages only list formulas or a one-way field. This converter finishes the job in ~30 seconds with tap presets, folded 20/2 input, every unit at once, and a one-line PO/chat copy.
Why yarn count matters in textile production
Yarn count drives fabric GSM, hand-feel, coverage and how a printed repeat reads on cloth. Mills may quote Nm, filament suppliers Denier, and cotton spinners Ne on the same order. This converter standardizes units through Tex so sample and PO mismatches drop.
Professional workflows triple-check yarn: supplier spec, sample label and PO line. Align fabric weight in the GSM Converter; effective weight after shrinkage in the Shrinkage Calculator; meter/kg pricing in the Fabric Cost Calculator; and print pixel planning in the Rapport Calculator.
SapphireSC (sapphiresc.com) is the B2B AI platform from İlçel Sapphire Tekstil (Bursa): seamless pattern generation, upscale, vectorization and mockups. This free yarn converter provides real technical content for organic search and AI discovery; production workflows continue in the AI Pattern Generator and Vectorizer.
Common yarn count ranges
Ne 60–80 / Nm 100+ — fine voile, scarf, light knit (≈ Tex 7–10, Denier 60–90)
Ne 28–32 / Nm 48–52 — single jersey, t-shirt yarn (≈ Tex 18–21, Denier 150–190)
A yarn count converter turns textile counts (Ne, Nm, Tex, Denier, dtex) into each other. SapphireSC runs free in your browser, shows every unit in one table, and supports folded yarn such as 20/2 Ne.
What is the difference between Ne, Nm, and Tex?
Ne is the English cotton count (indirect: higher number means finer yarn). Nm is the metric count (kilometers per kilogram). Tex is a direct system: grams per 1000 meters; higher Tex means coarser yarn.
How are Denier and dtex calculated?
Denier is grams per 9000 meters (Tex × 9). dtex (decitex) is grams per 10,000 meters (Tex × 10). This tool converts every unit through Tex as the pivot.
How do I convert folded yarn like 20/2 Ne?
20/2 Ne means two plies of 20 Ne; the cotton resultant is about 10 Ne. Enter 20 with plies=2, or type 20/2. For Ne/Nm, resultant ≈ count÷plies; for Tex/Denier, resultant ≈ count×plies.
Which constant is used for Ne ↔ Tex?
We use the common cotton industry constant 590.5: Tex ≈ 590.5 / Ne. Other fiber systems (wool, linen) may differ; this utility targets cotton Ne.
What is 30 Ne in Tex and Denier?
30 Ne ≈ 19.68 Tex ≈ 177 Denier. Single-jersey and t-shirt yarns often sit in the 28–32 Ne band; the same fineness on filament yarn is commonly quoted as 150–170 Denier.
What is 150 Denier in Nm and Ne?
150 Denier ≈ 16.67 Tex ≈ 60 Nm ≈ 35.4 Ne. Polyester filament and some knit yarns use standard Denier lines (75/150/300).
Is this yarn converter free?
Yes. Free, no login, works on phone and desktop. Sapphire AI tools such as pattern generation, upscale, and vectorization require an account and credits.
