If you want suit trousers with a crease that lasts through wear and cleaning, ask the factory in writing before the sample whether a durable crease is available for your cloth, because a crease in wool is normally pressed in, and a durable one needs a chemical treatment rather than heat alone — this page makes no claim that the factory applies one. Technology in Australia 1788-1988 records that the SI-RO-SET durable-crease process for pure wool was released in 1957, that wool cannot be heat set the way synthetics are, and that the process needed a chemical treatment of the garment just before final pressing, with changes in routine and equipment by the garment maker.

How do a pressed crease and a durable crease differ?
- Pressed crease: Set by steam and pressure in final pressing — Standard finishing for wool trousers
- Durable crease: Chemical treatment before final pressing — Ask in writing whether it is available for your cloth
- Blends: Cloth with polyester can be heat set — State the composition on the brief
- Check point: The crease on the sample — Look at it again after the client has worn the sample
What should the brief say about the crease?
- Crease yes or no (some casual trousers are left uncreased).
- Pressed or durable, as a question to the factory if durable — not as an assumption.
- The composition, since wool and blends behave differently.
Where does this sit on the clock?
Finishing is settled with construction: the sample (7–14 days) starts when measurements, cloth and construction are locked, and production (14–21 days) follows sample approval. On bulk from 50 per style, the sealed sample shows the crease for the whole run. Production days are not delivery days.

Is a trouser crease in wool permanent?
A pressed crease is set by steam and pressure and is renewed by pressing. A durable crease in pure wool needs a chemical treatment before final pressing; ask in writing whether it is available.
Do blended suit cloths hold a crease differently?
Yes. Synthetics such as polyester can be heat set, so blends can behave differently from pure wool. State the composition on the brief.
