Industrial washing of workwear according to SS-EN ISO 15797
Washing affects textile materials in several ways. The method is used to determine various properties such as dimensional change, wrinkling, seam puckering, general changes in appearance (pilling, fuzziness) after industrial washing.
The method is also used as pre-treatment of materials prior to testing of flammability or mechanical properties.
Purpose
The method simulates professional washing at an industrial laundry.
The washing properties of a textile material are an essential part of the quality experience. By testing these characteristics, it is possible at an early stage to predict what appearance and function will look like after washing.
Method
The method describes washing processes that simulates washing at an industrial laundry.
Eight different washing programs are described.
Wash temperature is 85 ◦C (full load = 20 kg cotton) or 75 ◦C (reduced load = 14 kg synthetic).
A standard industrial detergent is used (pH about 11.3) with or without bleach.
The drying method we can offer is tumble drying at max 80 ◦C.
It is possible to wash and dry at lower temperatures than the above mentioned as we program the washing machine and tumble dryer ourselves.
The method is always used in conjunction with any other test method that evaluates a particular property, e.g. dimensional change (SS-EN ISO 5077).
