A material for use in lining pipes includes inlay yarns that are interlinked by warp-knitted yarns. One set of inlay yarns extends in a machine direction, contributing to the fabric's strength in this direction. Two further sets of inlay yarns follow paths that step alternately between displacements to the left and right. This construction results in a series of short lengths of yarn aligned to provide the fabric with cross-directional strength. The inlay layers are loosely held, allowing them to slide relative to each other and the straight inlay yarns may move apart to a small degree. The result is a strong, flexible fabric that retains sufficient expansion for use in a pull-in-place liner.

A method of preparing a multilayered pipe-lining fabric involves repeated steps of layering flat sheets above and below a flattened carrier tube, bonding the sheets, then flattening the structure along fold lines circumferentially rotated from the first. Longer length and larger diameter tubular structures may be fabricated by this method, particularly heavier fabrics, such as those incorporating glass fibres.

A yarn includes elongated pieces of expanded graphite sheet and a tubular member made of knitted or braided fibers. In the tubular member, the pieces of expanded graphite sheet are twisted and packed. The yarns are knitted, or bundles of the yarns are twisted to form a gland packing.

An integrally woven or knitted textile, such as a tubular graft or sheet, having a base textile layer, in the case of a graft, it has at least one longitudinal tubular graft portion, and at least one pouch or flap integrally woven from at least a portion of the same set of yarns. Methods of making the same are also disclosed.

A protective textile sleeve for routing and protecting elongate members against impact and method of constructed thereof are provided. The sleeve includes a plurality of yarns interlaced with one another, with the interlaced yarns forming an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends. At least some of the plurality of yarns include tubular yarn having a central cavity extending along the length of the tubular yarn, thereby providing an impact resistant, dual layered wall to the tubular yarn. The sleeve can be constructed in a weaving, braiding or knitting process, wherein the tubular yarn can be interlaced as a woven yarn, braided yarn, or knit yarn, and further, the tubular yarn can be interlaced as an inserted yarn.

An integrally woven or knitted textile, such as a tubular graft or sheet, includes a base textile layer and at least one pouch or flap. In the case of a graft, the textile has at least one longitudinal tubular graft portion, and at least one pouch or flap integrally woven from at least a portion of the same set of yarns. Methods of making the same are also disclosed.

An all-wire weft-knit tubular sleeve can be knit from a plurality of electrically conductive wire filaments. Further, an electrically conductive bus wire can be interlaced in the weft knit pattern of the tubular sleeve to provide improved electrical contact along the entire length of the gasket. The exemplary weft-knit sleeve can allow for at least a 15% axial stretch without breaking the bus wire. The conductive wire filaments can be a copper/nickel alloy having a wire diameter of between about 0.075 mm and about 0.1 mm, a tensile strength of between about 70-125 KSI and an elongation of at least 12%.

A warp knit textile sleeve is provided. The sleeve has an elongate, wrappable wall extending along a longitudinal axis between opposite ends. The wall has opposite free edges extending lengthwise along the longitudinal axis between the opposite ends. The wall is knit from at least one warp yarn extending lengthwise between the opposite ends and a plurality of weft yarns extending circumferentially between the opposite free edges. The weft yarns form a plurality of discrete, annular bands alternating in adjacent relation along the longitudinal axis. The weft yarn of one of the adjacent bands has a first diameter and the weft yarn of the other of the adjacent bands has a second diameter, wherein the first diameter is less than the second diameter.

Embodiments disclosed herein include a knitted diverter that includes a main body defined by wire defining struts and loops having a density that reduces flow through an aneurysm, fistula or other similar anomaly.
