Patent number: 11371168Abstract: Disclosed is a method for producing an antimicrobial heat-retaining fiber. The method includes spinning a spinning solution onto a fiber-forming resin. The spinning solution includes 1.0 to 6.0% by weight of carbon particles and 0.2 to 2.0% by weight of a metal alkoxide coupling agent. The spinning solution further includes 0.5 to 3.0% by weight of inorganic particles composed of a metal powder, a ceramic powder, or a mixture thereof By using the metal alkoxide coupling agent, the carbon particles and the inorganic particles are dispersed in a resin. Also disclosed is a fiber produced by the method. The fiber is prevented from breakage during spinning and is imparted with heat-retaining and antimicrobial functions due to the presence of the carbon particles and the inorganic particles. Further disclosed is a fabric manufactured using the fiber. The fabric can be prevented from deterioration of wash fastness.Type: GrantFiled: August 14, 2012Date of Patent: June 28, 2022Assignee: G.CLO INC.Inventors: Hyung-jin Son, Jae-hun Jung, Tae-won Son, Chang-mok Son
