Pourquoi certaines trames deviennent-elles sèches après les premiers lavages?
No matter how high-quality the fabric, after any number of washes, it seems like the material always loses its luster and can become quite dry. While this is an expected consequence of washing clothing, the process behind losing moisture quickly is not well understood. Understanding why fabrics lose water molecules after multiple washes can help us make certain that fabrics remain moist and maintain their quality.
The main reason why fabrics become dry after washing is because of water hardness. As water evaporates, it leaves behind minerals on the fabric, which can then cause the fabric to lose water more quickly. The most common type of mineral that is left behind is calcium, which binds to fabric and makes the fabric more crunchy, ultimately losing its natural softness and suppleness.
Another factor that can affect the dryness of fabrics is the detergent that is used in the wash. Some detergents contain an excess amount of surfactants, which can break down the protective waxes and oils that are naturally present in fabrics. This can make it more difficult for the fabric to hold moisture, resulting in a drier feel after multiple washes.
Ultimately, the best way to avoid fabrics becoming dry and losing their softness is to use proper resources for each wash. Using hard water softeners can help remove the minerals from water, while also using a detergent that is gentle on fabrics can help maintain the natural oils and waxes in the fibres. Additionally, taking an extra step of rinsing the fabric after washing can help remove any residue that may remain on the surface. With these steps, one can ensure that their fabrics stay just as soft and adorable even after multiple washes.
