Method of dyeing a corespun yarn and dyed corespun yarn |
摘要 |
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 "grin through" and little to no yarn strength loss after dyeing. |
