A finish is a treatment applied to woven fabric after weaving, and usually after dyeing, to change its handle, appearance or performance. The common options from Indian mills include peach or emerised finishes for a soft surface, mercerising for lustre and strength, resin finishes for wrinkle resistance, durable water repellent for outerwear, and mechanical finishes such as calendering and sanforising. Each adds cost and processing time, and some trade one property for another. The buyer's job is to specify the result wanted and to test for it, rather than to assume the finish name alone guarantees performance.
The main finishes
- Peach or emerised finish: the fabric passes over abrasive rollers that raise a fine surface fuzz, giving a soft, suede-like touch. It can reduce tensile and tear strength slightly and can show wear at seams and edges.
- Mercerising: cotton is treated with caustic soda under tension, which swells the fibres and improves lustre, dye uptake and strength. Mercerised cotton takes colour more evenly and looks brighter.
- Resin or wrinkle-free finish: a cross-linking resin is cured into the cellulose so the fabric recovers from creasing. It improves easy care but typically lowers tear strength and abrasion resistance, and formaldehyde release must be controlled and tested.
- Durable water repellent: a chemical treatment that makes water bead and run off. Fluorine-free chemistries are now widely offered; specify this if your market restricts PFAS.
- Calendering: the fabric is passed between heated rollers for a smooth, flat, often glossy face. The effect may wash out unless it is set with resin.
- Sanforising: controlled compressive shrinkage that pre-shrinks the cloth so garments stay in size after washing, usually to a residual shrinkage of around 1 per cent.
- Softeners and enzyme washes: silicone or cationic softeners for handle, and enzyme treatments to remove surface fuzz and give a clean, worn-in look.
What to test and specify
Ask for the finish by result, with a test method and an acceptable value. For wrinkle-free, that is a crease recovery or smoothness appearance rating after a set number of washes, using AATCC or ISO methods. For water repellent, a spray rating before and after washing. For any resin finish, a free formaldehyde test to the limit your market requires, and for chemical finishes generally, inputs that comply with ZDHC or carry OEKO-TEX certification.
Check tensile and tear strength on finished fabric, not on greige, since peach and resin finishes both reduce it. Keep a sealed approved finish standard so the bulk can be compared to it by hand and by lab, because the words soft or peach mean different things at different mills.
How Creston & Co helps
We check finishes the practical way: an approved sealed sample is tested at an NABL-accredited lab, and bulk rolls are compared to it before loading. We visit the processing house, confirm the chemistry in use, and supervise loading so what ships is what was approved. We send weekly updates throughout, and a free 20-minute sourcing review is a good place to discuss a finish you have not bought before.
