wrinkleresistant

Wrinkleresistant is a textile property describing fabrics or garments that resist wrinkling and maintain a smooth appearance after laundering, wear, or storage. The term is commonly found in product labeling and is influenced by fiber type, weave or knit structure, and finishing processes. It is closely related to the concept of durable-press or permanent-press fabrics.

Achieving wrinkle resistance involves three main factors: fiber composition, fabric structure, and chemical finishing. Synthetic fibers such as polyester and blends with nylon or elastane naturally hold creases less than 100% cotton or linen. Tighter weaves or knits reduce crease formation. Finishing uses crosslinking resins or alternative chemistries that bond fibers together to resist creasing; many modern systems are formaldehyde-free and designed to be durable through multiple wash cycles.

Performance and care: wrinkleresistant fabrics may feel stiffer due to the finish, and over time the effect may diminish as resins wear. Laundering and ironing instructions typically emphasize low heat, tumble drying, or steam to refresh the look. Some items are marketed as requiring little to no ironing.

Considerations: historical wrinkle finishes used formaldehyde-based resins, which raised health and environmental concerns. Contemporary production often uses safer formulations with reduced emissions and certifications to reflect environmental standards. Labeling may advise on washing, drying, and ironing to maintain wrinkleresistant properties.

Applications include dress shirts, pants, sheets, bedspreads, uniforms, and other textiles where a neat appearance and reduced ironing are desirable. The term wrinkleresistant may appear in product descriptions, certifications, or branding, and practices vary by manufacturer and region.
