Patent number: 10982355Abstract: A knit sleeve for providing thermal protection about an elongate member contained therein and method of construction thereof is provided. The sleeve includes a knit inner wall with opposite edges extending lengthwise between opposite ends and a circumferentially continuous tubular outer wall knit integrally with the inner wall. The outer wall bounds a central cavity that extends lengthwise along a central axis between open opposite ends of the outer wall. The opposite edges of the inner wall are substantially parallel to the central axis and are wrappable toward one another to form the inner wall as being tubular. The circumferentially continuous tubular outer wall is configured to be everted about the wrapped inner wall to circumferentially surround and protect the inner wall from abrasion and provide the sleeve with a dual layer wall.Type: GrantFiled: July 24, 2017Date of Patent: April 20, 2021Assignee: Federal-Mogul Powertrain LLCInventors: Zhong Huai Zhang, Ritesh Mehbubani, Linwood Ludy

Patent number: 9745679Abstract: A wrappabie knit textile sleeve and method of construction thereof are provided. The sleeve includes a wall of knit yarn having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends with a straightened length of the wall spanning between the opposite ends. The knit yarn includes warp yarns extending generally parallel to the longitudinal axis and weft yarns extending generally transversely to the longitudinal axis. The opposite edges are wrappable into overlapping one another to form a tubular cavity. At least one of the weft yarns is an electro-functional yarn having a straightened length that is greater than the straightened length of the wall, thereby allowing opposite ends of the at least one electro-functional member to be pulled axially outwardly from the opposite ends of the wall to form leads for attachment to a power source.Type: GrantFiled: March 13, 2014Date of Patent: August 29, 2017Assignee: Federal-Mogul PowertrainInventors: Zhonghuai Zhang, Tianqi Gao, Cassie M.
