Workwear labelling follows a different logic from retail apparel: a single garment may go through a hundred industrial washes in two years, standard care labels fade, curl or fall off, and once the size or staff number becomes unreadable, sorting and returns break down.
This guide explains how industrial laundry actually damages labels, what the ISO 15797 test procedure tells you, when to choose woven versus coated labels, and what to confirm at the sampling and acceptance stages of a uniform project.
1. How Workwear Labelling Differs From Retail
Retail labels address consumers and stay within normal domestic washing. Workwear labels address a laundry plant, where the pressure comes from alkaline detergents, high temperatures, mechanical action and tumble drying. The same label can last ten times longer in one setting than the other.
- Wash conditions: 30–40°C at home against 60–85°C alkaline washing in industry, plus high-temperature pressing or tumble drying
- Service life: a retail garment is sold once; workwear circulates through rental or centralised laundry, so the label must cover many wash cycles
- Who reads it: consumers look at brand and composition; the laundry plant and uniform management look at size, staff number, barcode or RFID
- Reordering: uniform orders follow headcount plus a spare ratio and reorder more often than retail, so specifications must be archived for exact repeat runs
2. Why Industrial Laundry Breaks Labels
Failure is rarely caused by a single wash; it accumulates — fibres relax, coatings lift, ink migrates, stitching wears through. Understanding these four mechanisms keeps material decisions away from price alone.
| Failure mode | Main cause | Countermeasure |
|---|---|---|
| Fading, blurred text | Alkaline conditions and heat let dyes migrate and soften the ink | Choose alkali-resistant coated labels, or woven labels where the text comes from coloured yarn rather than surface ink |
| Curling, distortion | High shrinkage and dimensional instability at temperature | Use pre-shrunk, tightly woven tape or a polyester base |
| Coating lifting | Weak adhesion between coating and base; repeated mechanical action peels it away | Check coating uniformity and edge sealing, and validate with a wash test when in doubt |
| Stitching failure, label coming off | Cotton thread degrades faster in alkaline conditions, and one-edge stitching concentrates the load | Switch to polyester or core-spun polyester thread and stitch the label on all four sides |
3. ISO 15797: The Yardstick for Durability
ISO 15797 is the international standard for industrial washing and finishing procedures used to evaluate how textiles and trims hold up under laundry-plant conditions. When a brand specifies industrial-wash resistance, the specification should state the test procedure and the number of wash cycles; suppliers should test at the sampling stage rather than rework after a bulk failure.
4. Choosing Materials and Fixing Methods
| Option | Best for | Watch out for |
|---|---|---|
| Satin woven label | Brand main labels and uniform identification | Great hand feel, though edges fray under long high-temperature washing — fold all four edges |
| Tightly woven plain label | Workwear washed often and long | Dimensionally stable; letters come from yarn, so there is no ink to lose |
| Coated care label (nylon or polyester) | Workwear with long composition and care content | Sharp print at a workable cost; prioritise an edge-sealed finish |
| Heat transfer or printed label | Multicolour or graphic identification | Confirm base material match and wash rating to avoid lifting edges |
| Heat-seal no-sew label | Next-to-skin fabrics and seam-free appearance | Confirm the pressing conditions and re-check adhesion after washing |
Fixing matters just as much: a label stitched on one edge gets pulled and torn inside a drum, while four-edge or twin-needle stitching holds. Use polyester or core-spun polyester thread — cotton degrades faster in industrial alkaline washing.
5. Sizes, Staff Numbers and Asset Tracking
- Size labels: workwear sizing often pairs height with chest (for example 170/96A), so the label needs enough character width rather than compressed type
- Name and staff number: woven name labels or heat-transfer labels work well; in high-turnover sites add a barcode so issuance and collection can be scanned
- UHF RFID: suited to managing workwear assets across wash cycles; choose the chip by cycle count and make sure the stitching position does not press on the antenna
- Placement rules: centre back neck, side seam and inner waistband each have trade-offs — agree the reading position with the laundry before the project starts
Unlike retail, workwear identification earns its value over the whole lifecycle: a label that stays readable for ten years costs less than one that is cheaper by a few cents.
6. Sampling and Acceptance Checklist
- Wash validation: run at least one simulated industrial wash on the sample and check colour fastness, coating adhesion and seam strength
- Colour tolerance: uniforms are reordered by batch, so state the acceptable colour difference and keep the approved sample on file
- Shrinkage: state the washing shrinkage of fabric labels to prevent stretched or squeezed lettering after the first washes
- Lead time and reorder quantity: uniform projects usually need fast replenishment, so confirm standard lead time and minimum reorder quantity up front
- Packing by group: packing by size, department or employee cuts the sorting work at the client's end
