Every garment that enters a dry cleaner or commercial laundry has to answer one question at every stage of the process: whose is this? Garment labelling and marking systems exist to answer it reliably, through washing, dry cleaning solvents, pressing heat and hundreds of cycles. Get identification right and lost garments, mixed orders and customer disputes largely disappear. Get it wrong and you pay for it in claims and reputation.
This is the pillar guide to garment identification for South African textile care businesses. It covers every marking method, when each is appropriate, and the equipment involved. Unicorp is the authorised South African distributor for Thermopatch, the world’s leading garment labelling manufacturer since 1934, and has supplied labelling systems locally since 1985.
The Two Families of Garment Identification
Temporary marking
Identifies a garment for the duration of one visit: a tag, label or marking that survives the cleaning process but is removed before the garment goes home. This is the classic dry cleaner’s workflow: mark at reception, process, assemble the order, remove the mark at collection. Temporary systems prioritise speed of application and clean removal.
Permanent marking
Identifies a garment for its working life: heat-sealed or sewn labels carrying a name, barcode or logo that survive hundreds of industrial wash cycles. Permanent marking is the standard for uniform rental fleets, hotel and hospital linen, workwear programmes, school clothing and care-home residents’ garments, where the same items circulate through the laundry endlessly. Unicorp’s labelling and marking range covers both families.
The Main Marking Methods Compared
Two of these deserve their own deep dives: our comparison of heat-seal vs sewn labels covers the permanent-label decision in detail, and our guide to RFID and barcode garment tracking covers automated identification for high-volume operations.
Heat-Seal Labelling: The Modern Standard
Heat-seal labelling has become the default for permanent garment ID because it combines speed, durability and flexibility. A printed or pre-printed label is bonded to the garment in seconds under a heat-seal machine’s heated plate, at a controlled temperature, pressure and dwell time. Done correctly, the bond outlasts the garment through industrial washing and dry cleaning.
A complete heat-seal system has three parts:
-
The heat-seal machine. A purpose-built press with accurate temperature control and consistent pressure. Thermopatch machines are the industry benchmark, built for decades of daily use.
-
Labels and consumables. Name tapes, barcode labels, size markers and logo emblems, in materials matched to the wash process they must survive. Thermopatch sells over 15 million labelling products a year worldwide.
-
Printing. Pre-printed rolls from the supplier, or on-demand printing in your own operation for variable data like customer names and barcodes.
Choosing by Business Type
-
Dry cleaners: temporary tagging for customer orders, plus a heat-seal station for the growing side business of marking school and care-home clothing for customers.
-
Uniform rental and workwear: permanent heat-seal ID on every garment, usually barcode-based, often combined with logo emblems. This is fleet management as much as labelling.
-
Hotels and hospitals: permanent marking of linen and staff uniforms so items return from the laundry to the right department. High wash temperatures demand industrial-grade labels.
-
Care homes and schools: name labelling of residents’ and learners’ clothing, a service dry cleaners and laundries can sell profitably with one heat-seal machine.
-
Garment manufacturers: brand, size and care labelling at the production stage, including tagless heat transfers.
Why Equipment Choice Matters
Labelling fails at the weakest point: a press with inaccurate temperature, inconsistent pressure or worn platens produces bonds that lift in the wash, and every lifted label is a lost garment waiting to happen. This is why serious operations buy purpose-built heat-seal machines rather than adapting craft heat presses. Thermopatch has manufactured labelling equipment for over 90 years and its machines are the standard across European and American laundries; Unicorp supplies and supports the range in South Africa with consumables held locally.
