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.

The invention relates to the light industry area, namely to material for production of the woven and knitted textiles, and can be used for the manual production of the carpets, runners, coverlets, blankets and other similar decorative objects. The object of this utility model consists in improvement of material for production of the woven and knitted textiles by way of the optimum combination of the material composition and texture (form) resulting in upgrading of its application characteristics, namely—getting softness, lightness, strength and elasticity in combination with the aesthetic and decorative properties. In addition, the diversification of products made of the applied material is present. Material for production of the woven and knitted textiles is composed of the tubular seamless knitted shell filled with a reinforcing filler, made of synthetic microfiber or of a mixture of synthetic and natural microfibers with a density of 0.010-0.030 g/cm.sup.3, and the shell is made of the cotton or wool added with a synthetic thread, at that the material diameter is not more than 8 cm, and the shell and the filler composition ratio are defined by the material functionality.

A yarn in which slipping of filler materials from a tubular member can be reduced while suppressing the manufacturing cost is provided. The yarn has a tubular member, and a plurality of filler materials that are formed into a strip-like shape, and is configured by loading the filler materials into the tubular member in a state where the longitudinal directions of the filler materials are made extending along the axial direction of the tubular member. In the yarn, the tubular member is configured by using wire material that is knitted so as to produce stitches. The wire material has arcuate loop portions that define parts of external shapes of the stitches. In a state where the tubular member is developed, the loop portions are expanded in a direction that is inclined with respect to a straight line that extends in the axial direction of the tubular member.

Metal alloy knit fabrics, thermal protective members formed therefrom and their methods of construction are disclosed. This unique capability to knit high temperature metal alloy wire that is drapable allows for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection. The metal alloy knit fabrics described herein overcome the limitations of current welded stainless steel mesh seal coverings by providing coverings that withstand higher operational temperatures than stainless steel, are wear and snag resistant, can be a separate seal layer or as a portion of an integrated seal construction, can accommodate tight curvature changes to achieve complex shapes without wrinkling or buckling, and can be joined in the knitting process, sewed or mechanically fastened, without the need for welding.

In order to manufacture a yarn in which filler materials are loaded into a tubular member, the method of manufacturing a yarn has a step of knitting a wire material to form the tubular member. In the step of knitting the wire material, knitting of the wire material is advanced by a plurality of knitting needles, which are placed substantially concentrically about a rotation axis, while revolvingly moving the knitting needles about the rotation axis. When a stitch is to be formed by the wire material, the wire material is prepared so that an arcuate loop portion, which defines a part of the external shape of the stitch, is expanded in a direction which, in a state where the tubular member is developed, is inclined with respect to a straight line that extends in the axial direction of the tubular member.

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%.

An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member configured to move between a collapsed configuration and an expanded configuration. The elongated tubular member may comprise at least one twisted filament, such as a knitted filament having a plurality of twisted knit stitches with intermediate rung portions extending between adjacent twisted knit stitches, or a plurality of helical filaments twisted with a plurality of longitudinal filaments.

A tubular knitted stent or stent graft for placement in a lumen or body passage is compressible, thus presenting a compressed outer diameter and a non-compressed outer diameter. The stent or stent graft has knitted loops each having a loop width, wherein the loop width to non-compressed outer diameter ratio is larger than 0.2 for at least one knitted loop.

Disclosed is a needle-pass paper cord made of paper. The paper cord is formed by means of weaving yarn made of paper, and the yarn has a cross-section that is similar to a circle formed of a thread folded to a point. The needle-pass paper cord is soft in texture and uniform in shape, can save on raw materials, and is easy to recycle or degrade at a later time.

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.
