Abstract: The present disclosure provides a knit fabric including at least one continuous copper filament formed into a knit fabric including a layer of knit copper fabric having a first major plane and at least one loop of copper filament extending out of the first major plane. A knit fabric is also provided that has an interlock pattern including at least two continuous copper filament paths per layer. A further knit fabric is provided that includes a spacer fabric knit having a first layer of knit copper fabric interconnected with a second layer of knit copper fabric. Methods of making the knit fabrics are provided, including twisting or wrapping at least one continuous copper filament with a load-carrying yarn. The load-carrying yarn exhibits a minimum bend radius that wraps around an object having a diameter of 0.43 millimeters. The methods further include setting at least one tension setting on a knitting machine and using a knitting program that defines a plurality of stitch settings to knit a fabric.

Abstract: A vacuum molding roll sleeve (100, 700, 800)comprises a body (119, 818, 819) comprising a mold wall portion (120, 820) disposed between a molding surface (110, 1210, 710, 810) and at least one vacuum surface (130, 830). The molding surface (110, 1210, 710, 810) has shaped depressed features and has first openings (112, 812) disposed therein at first predetermined positions (134). Each first opening (112, 812) is spaced apart from the at least one vacuum surface (130, 830) by a respective minimum thickness (135, 835). The at least one vacuum surface (130, 830) has second openings (132, 832) disposed therein at second predetermined positions (134). The first openings (112, 812) are fluidly connected to the second openings (132, 832) by conduits (140, 840) wherein, on a respective basis, at least some of the conduits (140, 840) are longer than the minimum thickness (135, 835) between the first openings (112, 812) and the vacuum surface (130, 830). The vacuum molding roll sleeve (100, 700, 800) is configured such that at least partial vacuum can be applied to the first openings (112, 812) through the conduits (140, 840) fluidly connected thereto. The vacuum molding roll sleeve (100, 700, 800) is mountable on a backup roll (737). Methods of making and using the vacuum molding sleeve are also disclosed.
