Wrinkle-resistant
Chemical finishes (e.g., resin) cross-link fibers in cotton/poly blends to prevent creasing, ideal for business wear/shirts. Moderate cost, batch-processing via immersion; over-treatment may reduce breathability.
Waterproof coating
Polymer layers (PU/TPU) or membranes (ePTFE) repel water on outdoor/activewear. Basic coatings are affordable, high-tech like Gore-Tex costly; spraying is easy, lamination complex (balances water resistance and breathability).
Antibacterial treatment
Agents (silver ions, zinc oxide) inhibit microbes in sportswear/underwear. Low cost for dip treatments, medium for durable finishes; cross-linking ensures wash-resistance without skin irritation.
