Thin blue fibers of rayon are formed. After some time, sulfuric acid reacts with the complex compound and washes out the copper salts from the fibers. The fibers become colorless. Cuprammonium rayon is a rayon fiber made from cellulose dissolved in a cuprammonium solution, [1] Schweizer's reagent. [2]
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
Fabric softener must not be used; [7] the oils and cationic surfactants in the softener and self-softening detergents will clog up the fibers and make them less absorbent until the oils are washed out. Hot temperatures may also cause microfiber cloth to melt or become wrinkled. [7]
Recommended care for regular viscose rayon is dry-cleaning only. HWM rayon can be machine-washed. [34] Regular rayon has lengthwise lines called striations and its cross-section is an indented circular shape. The cross-sections of HWM and cupra rayon are rounder. Filament rayon yarns vary from 80 to 980 filaments per yarn and vary in size from ...

Stool softener , anionic surfactants that enable additional water and fats to be incorporated in the stool, making it easier for them to move through the gastrointestinal tract.
Acetate differs from rayon in the employment of acetic acid in production. The two fabrics are now required to be listed distinctly on garment labels. [8] Rayon resists heat while acetate is prone to melting. Acetate must be laundered with care either by hand-washing or dry cleaning. [9] [10]
