Hohenstein Institute, the Germany-based international research and service centre, has developed a label code for wash care of workwear for professional laundries to ensure that such apparels are treated optimally for continued performance over long term. The Institute has developed a catalogue of requirements that can be used to competently assign the wash care symbols to various workwear apparel items. The care symbols are based on the standard DIN EN ISO 30023 “Textiles – Qualification symbols for labelling workwear to be industrially laundered” that was specifically developed for industrially laundered workwear. Additionally, the test washing procedures are defined in accordance with the standard DIN EN ISO 15797 “Textiles – Industrial washing and finishing procedures for testing of workwear” that lists requirements for the machine technology, washing procedure, detergent, and drying procedure.
