The Workwear Glossary.

The US standard for high-visibility safety apparel, equivalent in role to EN ISO 20471 but with different garment classes. Defines Type O (off-road, e.g., warehouse), Type R (roadway, vehicle traffic exposure), Type P (public safety, emergency responders). Within each type, Class 1, 2 or 3 indicates required fabric area. Required by US OSHA for any worker exposed to vehicle traffic. We routinely produce to both ANSI 107 and EN ISO 20471 standards on the same line.

A topical or built-in textile treatment that inhibits bacterial growth, reducing odor and pathogen transmission. Common treatments: silver ion (Ag+), zinc pyrithione, quaternary ammonium compounds. Standard certification: AATCC 100 (US) or ISO 22196 (international). Required for healthcare uniforms (scrubs, lab coats) and increasingly specified for hospitality (chef wear, server uniforms) and food processing. Treatment performance is rated by wash-cycle retention (50+ cycles is standard).

Acceptable Quality Limit per ANSI/ASQ Z1.4. AQL 2.5 is the standard inspection level for general workwear: an inspector pulls a statistical sample (typically 80-200 pcs from a 5,000-pc lot) and the lot is accepted if defects in the sample stay below 2.5% major / 4.0% minor. Vanta Workwear's standard QC is AQL 2.5 with optional buyer-paid upgrade to AQL 1.5 (tighter, used for hi-vis safety-critical garments) or AQL 4.0 (looser, used for promotional t-shirts).

HRC (Hazard Risk Category) is a NFPA 70E classification of arc-flash protective clothing by arc thermal protective value (ATPV). HRC 1 = 4 cal/cm², HRC 2 = 8.7 cal/cm² (standard for most electrical work), HRC 3 = 25 cal/cm² (substation, switchgear), HRC 4 = 40 cal/cm² (high-energy work). The ATPV is measured per ASTM F1959. Always specify both the HRC category AND the specific ATPV value when sourcing electrical workwear.

A dense zigzag stitch (typically 42 stitches per bartack) applied at points of repeated stress: pocket corners, belt loops, fly endings, sleeve placket tops, label corners. Bartacks prevent stitching from unravelling under repeated tension. The presence and quality of bartacks is one of the fastest tells of workwear construction quality. Cheap workwear skips bartacks or uses sparse single-line reinforcement; quality workwear has 8-14 bartacks per garment.

A code of conduct and audit framework run by Amfori covering wages, working hours, freedom of association, health and safety, and forced labor. BSCI audits result in a rating A through E plus a corrective action plan. Required by most major European workwear brands and retailers for their China sourcing. Our facility holds a current BSCI audit rating with documentation available for buyers on signed RFP.

A branded high-tenacity nylon 6,6 fiber from Invista (formerly DuPont) engineered for abrasion resistance, tear strength and durability. Commonly woven into workwear reinforcement panels (knee patches, elbow patches, tool pocket linings) at 500-1000 denier. Cordura 1000D has abrasion resistance 4-5x higher than standard cotton canvas at the same weight. Premium hard-wear cargo pants and bags use full-panel Cordura construction.

The most comprehensive Incoterm. The seller handles every cost and risk from factory through customs at destination to delivery at the buyer's named address (usually a warehouse). Includes ocean freight, customs clearance, import duty, VAT/GST, and last-mile delivery. We offer DDP terms to North America (US/Canada), Europe (EU/UK) and Australia for buyers who prefer landed cost over per-stage logistics management.

Measured in stitches per square millimeter or expressed as stitch count per logo. A typical chest-position corporate logo runs 4,000-12,000 stitches at 100% fill density. Higher stitch density means stronger, more vibrant logo but higher unit cost. For FR workwear, embroidery thread must be FR-rated (Nomex or Kevlar thread) at the same density specification.

The European equivalent of NFPA 2112, covering protective clothing for workers exposed to heat and flame in industrial environments. Specifies six performance codes (A through F) for convective heat, radiant heat, molten metal splash, etc. Most welding and oil & gas FR programs require EN 11612 + EN 1149-5 (anti-static) combined. We produce to both EN 11612 and NFPA 2112 standards on the same FR line, allowing the same fabric to ship to EU and US buyers with the appropriate test reports.

The European standard for high-visibility warning clothing. Defines three performance classes: Class 1 (lowest, e.g., delivery on private property), Class 2 (mid, e.g., warehouse and forklift environments), and Class 3 (highest, e.g., road crews and rail). Class is determined by the minimum area of fluorescent background fabric (0.14-0.80 m²) and retroreflective tape (0.10-0.20 m²). Every hi-vis workwear PO we ship includes the type-3 test report tied to fabric lot.

An international shipping Incoterm specifying that the seller's responsibility ends when goods are loaded onto the vessel at the named port of origin. After loading, the buyer assumes risk and cost (ocean freight, insurance, destination handling, customs). Most of our workwear customers ship FOB Shanghai or FOB Ningbo. Buyer typically arranges their own freight forwarder; we deliver to the named container freight station.

A voluntary international standard set by Textile Exchange that verifies recycled material content, chain of custody, social and environmental practices, and chemical restrictions throughout the supply chain. A GRS-certified RPET workwear program lets the brand claim recycled content with audit-trail backing. Minimum 20% recycled content to be certified; most RPET workwear runs 65-100% recycled. Required by most large EU sustainability-focused logistics and corporate buyers.

Grams per square meter is the unit-area weight of a textile. For workwear, GSM ranges from about 150 (lightweight hi-vis polyester knit) to 320+ (heavy industrial coverall twill). Higher GSM generally means more durability, longer life under industrial laundry, slower drying time, and higher unit cost. Always specify GSM with a tolerance (typically +/- 5%) and measurement standard (ISO 3801 or ASTM D3776).

A triangular or diamond-shaped fabric panel inserted at high-motion points (underarm, crotch, knees) to add range of motion without splitting seams. Common in industrial coveralls (underarm gusset for arm raise), cargo pants (crotch gusset for squatting), and chef trousers (saddle gusset). A coverall without a gusset will tear at the underarm within 100 wash cycles under repeated overhead reaching.

Decoration process where a vinyl logo is laser-cut from a sheet, weeded (excess removed), then heat-pressed onto the garment. Excellent for individual name personalization (faster than embroidery for one-off names) and for hi-vis reflective transfer logos. Reflective HTV provides retroreflective branding without compromising garment hi-vis class. Survives 30-50 wash cycles before edges begin to lift; lower lifecycle than embroidery.

An international standard for quality management systems issued by the International Organization for Standardization. Certifies that a manufacturer has documented processes for quality control, continual improvement, customer-focused operations, document control and corrective action. Audited annually by accredited certification bodies (TÜV, Bureau Veritas, SGS). Our facility holds current ISO 9001:2015 certification.

A high-performance aramid synthetic fiber that is inherently flame-resistant — the FR property is built into the polymer chain, not applied as a topical treatment. Used in NFPA 2112 and EN 11612 garments. DuPont's branded version is Nomex; equivalent fibers include Teijinconex and Kermel. Typical FR workwear fabric is a meta-aramid blend (93% meta-aramid + 5% para-aramid + 2% antistatic carbon fiber). Survives industrial laundry without losing FR performance, unlike FR-treated cotton.

Polyester fabric engineered with capillary channels in the fiber cross-section that pull moisture away from the skin surface and spread it across the outer fabric for fast evaporation. Common in performance polo shirts and athletic workwear. Specified by tested wicking rate (mm of fabric area wetted in 30 sec) and drying time. Should be the default fabric for hot-environment workwear (warehouse, automotive workshop, hospitality kitchens).

The minimum number of garments per style, per color, per size combination that the factory will produce. Vanta Workwear's standard workwear MOQ is 100 pcs per style per color. Some specialty categories (FR meta-aramid, OR-grade surgical scrubs) have a higher fabric-driven MOQ of 200-300 pcs. Multiple sizes within the same style/color count toward a single MOQ, so a 100-pc order can span sizes XS through 4XL.

The US National Fire Protection Association standard for flame-resistant garments protecting industrial personnel against flash-fire exposure. Mandatory in many upstream oil and gas, midstream pipeline and downstream refinery operations. NFPA 2112 garments must self-extinguish, not melt, and limit body burn injury to <50% per ASTM F1930 manikin testing. Every NFPA 2112 garment we ship includes the fabric-lot-specific third-party test report from accredited labs (UL, SGS, Intertek).

A third-party certification testing finished textile products for over 350 harmful substances including formaldehyde, heavy metals, pesticide residues and banned azo dyes. Issued in four product classes (I-IV) by skin-contact intensity. Class I (strictest, suitable for babies). Class II is required for direct-skin-contact workwear (shirts, scrubs, polo shirts) and is our default. Class III for outerwear, Class IV for furnishings. Issued by the OEKO-TEX Association via certificate from accredited testing institutes.

The process of matching a fabric dye color to a specific Pantone reference (typically Pantone Coated or Pantone TPX/TCX for textiles). Performed via lab dips — small fabric swatches dyed against the target, compared visually and spectrophotometrically (Delta-E < 1.5 for solid colors is the working tolerance). Lab dips are issued to the buyer for sign-off before bulk production. Pantone-matched colors are stored on file for repeat orders.

A spinning method where cotton fibers are pulled, twisted and wound onto a ring frame. Produces stronger and smoother yarn than open-end (rotor) spinning, at about 15-25% higher cost. Should be the minimum yarn standard for any commercial-grade workwear cotton fabric. Ring-spun workwear survives 150-200+ industrial wash cycles; open-end yarn shirts degrade by wash 50.

A textile weave construction with heavier-denier reinforcement threads woven into a grid pattern (typically 5-8mm squares) throughout the lighter base fabric. The reinforcement grid stops a tear from propagating beyond a single grid cell — even if the fabric snags and tears, the rip is contained to a small area instead of running the length of the garment. Used in construction workwear, FR coveralls, outdoor and military workwear. Identifiable by the visible grid pattern on the fabric surface.

Polyester fiber produced by recycling post-consumer PET plastic bottles. Each ton of RPET fiber diverts roughly 35,000 plastic bottles from landfill. Performance is identical to virgin polyester for workwear applications (hi-vis, polos, jackets), at a price premium of 8-15%. Required by an increasing share of European and large logistics-program buyers as a sustainability claim. Look for GRS (Global Recycled Standard) certification to verify recycled content claims.

A printing process where ink is pushed through a fine mesh stencil onto fabric, layered one color at a time. Best for solid-color logos with sharp edges and limited color count (1-6 colors typical). Cost-effective at volume (50+ pcs per logo). Plastisol inks are standard for cotton, water-based inks for soft-feel premium prints. Survives 50-100 industrial wash cycles before significant fade. Common on workwear t-shirts, hoodies and back-panel branding.

A printing process where dye is heat-transferred (sublimated) into polyester fibers, producing photographic-quality color with no surface texture. Works only on polyester fabric (or polyester-blend with > 65% poly content). Used for hi-vis polos with all-over team colors, dye-sublimated team uniforms, full-color graphic workwear. Survives industrial laundry indefinitely because dye is embedded in the fiber rather than printed on the surface.

A document used to communicate a garment design and specification from buyer to manufacturer. Typically includes a flat sketch (front, back, side), construction details (seams, stitching, hardware), measurement chart (size run), fabric and trim specifications, label and packaging details, and decoration placement. A good tech pack reduces sampling rounds. We can also write a tech pack for buyers who supply only a sketch or sample garment.

A textile weave with a diagonal rib pattern, produced by passing the weft thread over two warp threads then under one. Twill is the default workwear fabric weave because it offers strong abrasion resistance, drapes well, hides stains and creases less than plain weave. Common twill workwear fabrics: 65/35 poly-cotton twill (general workwear), 100% cotton twill (chef wear), nylon twill (rain gear), meta-aramid twill (FR coveralls).
