Mineral wool is a stone-based mineral fiber insulation comprised of Basalt rock and recycled steel slag. It costs about about 25% to 45% more than fiberglass, but I feel its benefits more than justify the additional costs.
Acrylic is our final fiber. It can be thought of as artificial wool. It is made from the unlikely combination of coal, air, water, oil and limestone. DuPont first made acrylic fibers in 1944 and began commercial production in 1950. It is spun by either dry spinning or wet spinning. In dry spinning the dissolved polymers are extruded into warm air. The fibers solidify by evaporation. In wet spinning the polymer is dissolved and extruded into a bath and then dried. In some ways, acrylic imitates wool. It has wool's warmth and softness, but does not absorb water. Instead, acrylic wicks moisture to the surface where it evaporates.
