What it means
This is the acrylic, nylon, acetate and elastane setting, and the no-steam part is not optional — ISO 3758 notes that steaming may cause irreversible damage at this level. Synthetics do not scorch the way cotton does; they melt, glaze and take on a permanent shine where the soleplate touched, and there is no way back from that. Use a pressing cloth, work from the reverse side, and check the setting on a hem before an entire front panel.
Defined by ISO 3758. Where a symbol differs between standards, the difference is described above rather than resolved — both versions are in circulation on real labels.
