What type of chemical is commonly used in laundry operations to reduce flatwork ironing time?

Fabric softeners are commonly utilized in laundry operations to reduce flatwork ironing time due to their ability to relax fabric fibers. When added during the laundry cycle, fabric softeners coat the fibers of the material, which not only helps reduce static electricity but also makes the fabric softer and more pliable. This results in less wrinkling and easier ironing, as the garments come out of the dryer in a smoother state.

In contrast, bleach is primarily used for whitening and stain removal and does not contribute to reducing ironing time. Detergents are essential for cleaning but do not specifically affect the ironing process. Starch, while it imparts stiffness and helps maintain a crisp finish in fabrics, can actually make the ironing process more challenging if not applied correctly, as it can lead to a stiffer texture that is harder to flatten. Thus, fabric softeners are more effective for meeting the goal of efficient flatwork ironing.
