Wool cloth was being spun and woven before 10,000 B.C. It was known as the “Golden Fleece.” Wool has several qualities that distinguish it from hair or fur. It is crimped, it is elastic, and it grows in clusters. Wool’s crimp makes it easier to spin the fleece by helping the individual fibers attach and stay together. Because of the crimp, wool retains air,which causes the product to retain heat. This makes wool a superior insulator. Because of this, wool keeps you cool in the summer and warm in the winter. Wool fibers are hydrophilic, meaning they readily absorb moisture. It can absorb moisture one third of its own weight. Wool ignites at a higher temperature than synthetic fiber. It doesn’t melt or drip, it forms a char which is insulating and self-extinguishing. Wool is considered hypoallergenic and antibacterial by the medical profession. It is resilient, no matter how it is crushed, pure wool filling springs back to its original thickness. Wool is a natural dust mite and bedbug repellant. It is also mold and mildew resistant. Wool is biodegradable and an ecofriendly product. It contributes to a more healthy sleeping environment. Wool fill is superior in comfort and lasts a long time. No animals are killed or harmed in the production of wool.
