Wool Processing and Dyeing Techniques

The video tutorial explains the journey of wool from production to processing at Pendleton Mills. It covers the dyeing process, where wool is dyed in various colors using a hydraulic press and a pressurized vat. The wool's hydrophilic nature helps it retain color. After dyeing, the wool is rinsed and dried using a microwave oven to preserve its quality without damaging the fibers.
