How is a tag built into a garment?
Sewn into a seam, heat sealed behind the care label, or held in a patch, with a flexible sealed body rather than a sticker. The garment sets the terms: it is washed, pressed and folded for years, and textiles are among the groups the ecodesign regulation named first.
Where the tag goes
The care label is the obvious home. It is already sewn in, already meant to stay for the life of the garment, and already the place a buyer looks for information about the item. An inlay laminated into a printed or woven label puts the tag there without adding an object.
A side seam or a waistband takes a sealed tag sewn or heat sealed in, which keeps it flat and away from the skin. A patch or a stitched pocket is the same idea with more labour and a better failure rate, because the tag is held rather than stressed.
Footwear is a moulding problem more than a sewing one. A cavity in the sole or under the insole takes the tag after the sole is formed, which is the second route of the moulding page rather than the first.
A hangtag reads perfectly and is removed at first wear, so it carries a message for the shop floor and nothing that has to last.
What the garment does to it
Fabric takes no adhesive, so attachment is sewing, heat sealing or enclosure, and the attachment is as much of the engineering as the tag. The laundry page makes the point for industrial linen and it holds for a wardrobe.
The wash is survivable with the right construction. The press and the iron are what destroy tags, because they put heat and pressure on the chip at the same time. Domestic ironing is the same profile at a smaller scale, and it is the step nobody writes into a specification.
Flexibility is deliberate. A rigid tag in a soft product is a stress concentrator that gets folded, sat on and pressed; a flexible body distributes what it cannot avoid.
Comfort and appearance cap the size, which caps the antenna and therefore the read distance. A garment tag is read close, on purpose, which makes the marked spot part of the design rather than an afterthought.
The textile passport question
regulation (EU) 2024/1781 required the first working plan to prioritise a list of groups, and textiles, in particular garments and footwear, are on it, as the coverage page sets out. A working plan is not an obligation on a product, and the obligations arrive with the delegated act for the group.
Three consequences reach the garment before any act does. The carrier has to outlive the product, which the availability page covers, and a hangtag cannot. The act says where the carrier goes, which the carrier page covers. And the act fixes the level of identification, which the level page covers: model, batch or item, and item level means a different address written into every garment on the line.
That last one is the expensive part of the sentence, because it changes a printing step into an encoding step with its own verification.
Specifying it
State the wash temperature, the dryer, and whether there is a press or an iron. Suppliers publish cycle counts and the figure depends heavily on the process, particularly the press.
Test the sewn assembly rather than the tag, for as many cycles as the schedule allows, and read after each one rather than at the end, so the failure has a cycle number attached to it.
Decide the tap point with the garment on a body, not flat on a table. A spot that is reachable on a hanger can be under an arm when worn.
And weigh NFC against a UHF system by the reading job. Reading one item deliberately with a phone is the NFC case; counting a container of items at a distance is not.
Frequently asked questions
Can a tag survive a domestic wash?
A tag built for it can. An ordinary sticker does not survive one cycle, and the iron or press is what kills tags rather than the water.
Where in the garment should it go?
Somewhere a phone reaches and a body does not rub: a care label, a seam, a patch. Comfort and the tap point pull in different directions, so decide at design time.
Can the hangtag carry the passport?
It leaves with the first wear. Anything that has to outlive the purchase belongs on a permanent label, and the act for the group says what is required.
Does every garment need its own identifier?
That depends on the level the act sets. Item level means a unique address written into each garment, which turns a printing step into an encoding step.
