Read the cross-section
The illustration shows a simplified coated fabric, not a laboratory section of an IRIS product. A surface finish controls gloss or texture, the PU coating provides a flexible leather-like face, and a woven or knitted backing supports it. Some fabrics add adhesive or foam layers; others use a different construction.
What each layer tells you
- Surface finishTreat gloss gently. Abrasion can change how it reflects light, even before an obvious scratch appears. Avoid rubbing one shiny surface against another during storage.
- PU coatingRepeated stretching, folding and ageing can weaken the film. Do not use the coating itself as a handle when dressing a tight sleeve or leg.
- Textile backingThe backing supports the garment, but that does not make the outer film indestructible. Guide fabric gradually along the body instead of pulling only at the cuff.
A repair is not a material reset
A detached coating and a loose stitch are different problems. Restitching may help a seam; it cannot reverse a chemically degraded coating. Stop wearing a piece that sheds flakes or becomes sticky, and keep it apart from other costumes until you can assess it.
Do not peel a lifted edge to investigate it. Photograph the area and ask the maker for advice before adding glue, paint or a repair compound. A repair may alter both flexibility and finish.
