Which term describes a fabric that has not been chemically treated to prevent wrinkling?

The term that describes a fabric that has not been chemically treated to prevent wrinkling is "natural." Natural fabrics, such as cotton, linen, silk, and wool, are made from fibers derived from plants or animals and typically do not undergo extensive chemical treatments during their production, which includes processes that would prevent wrinkling. This characteristic often leads to a more organic and less processed feel, aligning with consumer preferences for sustainability and eco-friendly materials.

While the other terms like "softened," "raw," and "unfinished" also pertain to specific states of fabric production, they do not specifically indicate the absence of chemical treatments designed to minimize wrinkling. "Softened" refers to a process that may involve chemical treatments to improve the tactile quality of the fabric, "raw" generally describes a fabric that has not been fully processed or refined but may still have undergone some treatments, and "unfinished" pertains to fabrics that are not yet fully complete in their final processing stages, which doesn’t specifically relate to wrinkle resistance.
