Provided is a novel method of dyeing a corespun yarn which comprises an inorganic fiber core and at least a first sheath. The method comprises: (a) contacting the corespun yarn with a dye liquor; (b) heating the dye liquor to a dyeing temperature for a time effective to dye the yarn; (c) cooling the dye liquor at a controlled rate; and (d) rinsing the yarn with water or with a mixture comprising the dye liquor and water. The dyed corespun yarn has a strength retention of about 80% or more based on the undyed yarn. The methods in accordance with the invention allow for the formation of uniformly dyed, high strength corespun yarns. Also provided is a dyed, corespun yarn which can be made by the inventive method, a fabric formed from the corespun yarn, as well as a product upholstered with the fabric. The dyed yarns exhibit substantially no &ldquo;grin through&rdquo; and little to no yarn strength loss after dyeing.

An apparatus is set forth to effect selective chilling of an extremity of an individual's appendage, such as the ankle and foot portion, wherein the apparatus includes a container with a cylindrical opening directed through an end wall thereof, with the opening including a clamping collar. The clamping collar includes an 'L' shaped bag member mounted thereabout, with a clamp securing the bag member to the clamping collar, and the bag member including an opening aligned with the cylindrical opening. A support is positioned underlying the bag member, with the container defining a cavity about the bag member to accept a chilling medium such as fluid and ice mixture.
