The Craft.

How we engineer custom workwear: the fabric program, the decoration house, the QC line, and the certifications backing every shipment. Written from inside the factory — the language a tech-pack reviewer or compliance officer actually needs.

Operating Principles

Three things we will not compromise.

A short list of operating principles that shape how we quote, sample, produce and ship. They are the reason our 18-month repeat-order rate sits at 81% across all programs.

VALUE 01

Audit-trail compliance.

Every hi-vis and FR shipment ships with a fabric-lot-specific third-party test report from a recognized lab (UL, SGS, Intertek, Bureau Veritas). Buyer-specific certificate holders are maintained on file. The audit trail is intact — your safety officer never has to write us at 11pm asking where the EN 20471 type-3 report is.

VALUE 02

Real merchandisers.

Every account has a dedicated merchandiser who knows your tech pack, your reorder calendar and your QC contact. Not a sales rep. Not a generic "service account". A workwear textile person who can answer the question "is 220 GSM enough for the wash cycle your laundry contract specifies?"

VALUE 03

Quality before yield.

We hold AQL 2.5 across all general workwear programs and AQL 1.5 on FR / hi-vis safety-critical garments. We let through-yield take the hit. A reject is cheaper than a returned container. The QC team operates independently of production and has authority to halt shipment.

01 / The Factory

Three production lines, one campus.

Our facility in Yiwu, Zhejiang sits on 22,000 square meters and houses three dedicated production lines — a general workwear line for polo shirts, work pants and shirts; a hi-vis specialty line for EN ISO 20471 / ANSI 107 garments with reflective-tape attachment stations; and a dedicated FR line for meta-aramid coverall work that runs separately to maintain certification integrity.

The factory is laid out in a linear flow: fabric warehouse → CAD cutting room → sewing line → decoration (embroidery / screen print / heat press / sublimation) → QC inspection → packaging. A standard polo program can move from raw fabric to packed carton in 11 working days when timing matters.

We added our dedicated FR production line in 2018 after demand from Middle East oil and gas customers passed the threshold to justify isolation. Today our FR program supplies refinery, pipeline and upstream oilfield uniform programs across three continents.

02 / Decoration House

Sixteen Tajima heads, four screen lines, two heat presses.

Our in-house decoration department is what most clients say sets us apart. Sixteen-head Tajima TMBP embroidery machines handle high-volume corporate, hospitality and construction-crew logo work. Four screen-print rotary tables handle 1-6 color back-panel prints and t-shirt programs. Two heat-press stations run individual name-patch personalization (HTV) and reflective transfer logo work. Two dye-sublimation lines handle full-color polyester polo programs.

Every embroidery file is digitized in-house — we don't outsource. That means we can recommend changes to your file when the original was created for a printed brochure and won't read well at 12,000 stitches per minute. Most clients send us a logo PDF; we send back a stitch-count estimate and a digital simulation within 24 hours.

For FR uniform programs, we use Nomex-rated and Kevlar-rated embroidery thread exclusively. Standard polyester thread melts under arc-flash and worsens burns — using FR-rated thread is a non-negotiable for any FR-certified garment.

03 / Fabric Program

From meta-aramid, from hi-vis polyester, from Cordura.

Our standard general-workwear ranges use 65/35 poly-cotton twill at 220-280 GSM — the workhorse fabric for shirts, polos, work pants and coveralls. We have been buying it from the same three mill partners since 2012, with consistent lot-to-lot performance documented in our fabric library.

For hi-vis garments we use EN ISO 20471-compliant fluorescent polyester (orange-red or yellow-green) at 150-220 GSM. The fabric is procured against the fluorescence and chromaticity coordinates in Annex A of the standard, with each lot tested for compliance before sewing starts.

For FR programs we use inherent meta-aramid blend fabric (93% meta-aramid + 5% para-aramid + 2% antistatic carbon fiber) at 220-280 GSM. Inherent FR means the protective property is engineered into the polymer chain — it does not wash out, does not degrade under industrial laundry, does not require re-treatment. For high-wear panels in construction and cargo pants we add Cordura 1000D reinforcement at the knees.

For sustainability-led buyer programs we run a separate GRS-certified RPET line — recycled polyester from post-consumer PET bottles, with full chain-of-custody documentation from bale to finished garment. Identical performance to virgin polyester at 8-15% premium.

04 / Quality Control

AQL 2.5, every carton.

Our QC team operates independently from production. They have the authority to halt shipment of any carton that falls below specification. Below: the seven-step inspection protocol every workwear order passes through before it leaves the factory.

01
Fabric inspection
Weight (GSM), color fastness, hi-vis chromaticity, FR test sample, OEKO-TEX certificate verified per lot.
02
Lab dip sign-off
Pantone match, Delta-E ≤ 1.5 sign-off before bulk dye on solid-color programs.
03
Cutting audit
Pattern accuracy, grain alignment, pile direction check before pieces enter sewing line.
04
Inline sewing QC
Stitch density (SPI), seam straightness, bartack reinforcement, label position checked at hourly intervals.
05
Wash test
Industrial wash ×5 cycles; check shrinkage under 5%, color fastness, reflective tape adhesion.
06
Decoration QC
Stitch density, registration, print sharpness, color match vs approved PPS sample.
07
AQL inspection
Independent inspector samples per ISO 2859-1, AQL 2.5 major / 4.0 minor (AQL 1.5 on FR / hi-vis safety-critical).
05 / Certifications

Audited by the right bodies.

A full set of internationally recognized certifications, issued by the bodies your compliance team will already trust. Fabric-lot-specific test reports per order on request, at no extra cost.

OEKO-TEX Standard 100, Class II
All direct-skin-contact garments tested for over 350 harmful substances. Class II is the required tier for workwear (shirts, polos, scrubs, t-shirts) in direct skin contact.

EN ISO 20471 & ANSI/ISEA 107 (Hi-Vis)
Hi-visibility safety apparel for traffic-exposed crews. We produce to both European and US standards on the same line, with type-3 test reports per fabric lot.

NFPA 2112 & EN 11612 (FR)
Flame-resistant workwear for oil & gas, welding, electrical. Test reports from UL / SGS / Intertek per shipment, tied to fabric lot for full audit trail.

ISO 9001:2015
Quality management system, audited annually by Bureau Veritas. Documents process control, corrective action and continual improvement.

BSCI / amfori Social Audit
Independently audited for fair labor practices, wages, working hours and safe working conditions. Required by most European workwear buyers.

GRS (Global Recycled Standard)
For our RPET (recycled polyester) hi-vis and polo programs, with full chain-of-custody documentation from bale to garment.

06 / Sustainability

Less water, less waste, more truth.

Sustainability in workwear manufacturing is more often a marketing exercise than an engineering one. We try to do it the other way around.

Since 2022 our facility has cut water consumption per kilogram of finished garment by 32% through low-liquor-ratio dyeing equipment and a closed-loop water reclamation system. We track and publish kWh, water and CO2 per kg as part of our annual ESG report.

For sustainability-led buyer programs we run a GRS-certified RPET line — recycled polyester from post-consumer PET bottles. Each kilogram of RPET fiber diverts roughly 35,000 bottles from landfill. All packaging defaults to FSC-certified kraft cartons and recycled-content polybags. Single-use plastic polybags are available but not the default.
