Which fabric finishing technique focuses on making fabric wrinkle resistant?

The technique known as permanently pressing is specifically designed to enhance the wrinkle resistance of fabric. This process involves applying heat and pressure to the fabric in such a way that it creates a lasting structural change in the fibers. The result is that the fabric maintains a smooth appearance even after washing or prolonged use, significantly reducing the need for ironing. This finishing technique is particularly beneficial for garments and home textiles, as it helps maintain a neat appearance and increases the overall ease of care for the consumer.

In contrast, softening refers to treatments that make the fabric feel softer and more comfortable against the skin, but it does not necessarily impart wrinkle resistance. Calendering, while it can flatten fabric and enhance its sheen, does not specifically target wrinkle resistance as its primary goal. Coating involves applying a layer of a substance to the fabric’s surface to achieve water resistance or other functional properties but does not inherently address the issue of wrinkles. Thus, permanently pressing stands out as the technique aimed directly at making fabric wrinkle resistant.
