A family of selectively absorbable / biodegradable, fibrous composite constructs includes different combinations of biostable and absorbable / biodegradable yarns assembled as initially interdependent, load-bearing components, transitioning to exhibit independent functional properties during in vivo end-use. The family of constructs consists of two groups, one group is made of fiber-reinforced composites of high compliance, absorbable matrices of segmented polyaxial copolyesters reinforced with multifilament yarn constructs, which are combinations of ultrahigh molecular weight polyethylene fibers and at least one absorbable / biodegradable fiber selected from silk fibers and multifilament yarns made from linear segmented, l-lactide copolyesters and poly (3-hydroxyalkanoates, are useful in orthopedic, maxillofacial, urological, vascular, hernial repair and tissue engineering applications. The second group is made of coated and uncoated, warp-knitted mesh constructs for use in hernial, vascular, and urological tissue repair and tissue engineering.

An article of footwear with a knit upper and a method of manufacturing the footwear are disclosed. The upper is formed through a knitting process to include a plurality of sections formed of different yarns and knits to provide the sections with different physical properties. In portions of the upper where sections formed of different yarns are in adjacent wales, a tuck stitch is utilized to join the sections. The method utilizes a circular knitting machine having multiple feeds that work together to knit the upper into a unitary, seamless structure. The multiple feeds, each of which provide multiple types of yarns, produce the sections to have varying physical properties.

A combined stent / graft structure for repair of a body tube in a living body. The structure includes a textile graft adapted to enhance fluid integrity of the body tube and a stent expandable between a first position permitting easy insertion of the stent into the body tube and a second position wherein the stent presses securely against the inside surface of the body tube. The stent includes a first elongate wire-shaped stent member with both a stent member global axis and a stent member local axis, and is integrally secured to the graft by at least one graft yarn of which the graft is formed. Substantial portions of the first stent member global axis form a non-orthogonal angle with the graft main portion axis when projected into a plane containing the graft main portion axis. A woven textile is also part of the invention as is a method of manufacturing such a woven textile, which can be used to produce stent / graft structures according to the invention.

This knit is produced on the basis of a biocompatible polymer material monofilament, whose pattern is defined by a front lap and a rear lap of yarns knitted together and determines a plurality of cells each having a substantially polygonal shape. The pattern gives the knit a multidirectional tensile behavior such as obtained by a front lap capable of being obtained by knitting according to a scheme 5-4 / 4-3 / 2-1 / 0-1 / 1-2 / 3-4 and by a rear lap capable of being obtained by knitting according to a scheme 0-1 / 1-2 / 3-4 / 5-4 / 4-3 / 2-1.

Fabrics, articles of apparel, and / or garment structures include infrastructure for transmitting information, such as signals produced by a wearer or from another source. Such fabrics may include: a textile formed through a knitting or weaving process, wherein at least one yarn used in the knitting or weaving process is electrically conductive to form sensor regions and / or other integrated electrically conductive infrastructure for transmitting electrical signals. Additional information is provided relating to methods for forming fabrics, articles of apparel, and / or garment structures of the types described above, as well as methods of using such products, e.g., for monitoring and / or displaying information regarding one or more physical and / or physiological parameters.

An electrical cable for shipboard use that can block water is disclosed. The electrical cable includes conductors, water swellable tapes, water swellable yarns, solid fillers, and a jacket. Each conductor is substantially wrapped with water swellable tape. The conductors are disposed adjacent to each other thereby forming interstitial voids between each of the conductors. Solid fillers and water swellable yarns are alternatively disposed in each interstitial void. Additional water swellable tape substantially envelopes the conductors, water swellable yarns, and solid fillers. The jacket is disposed on the outermost peripheral surface of the electrical cable.

Braids and surgical devices are made from yarns that include at least one filament made from a shape memory material.

Bi-directional and multi-axial fabrics, fabric composites, ballistically resistant assemblies thereof, and the methods by which they are made. The fabrics are comprised of sets of strong, substantially parallel, unidirectional yarns lying in parallel planes, one above the other, with the direction of the yarns in a given plane rotated at an angle to the direction of the yarns in adjacent planes; and one or more sets of yarns having lower strength and higher elongation interleaved with the strong yarns. The fabrics of the invention provide superior ballistic effectiveness compared to ordinary woven and knitted fabrics but retain the ease of manufacture on conventional looms and knitting machines.

A radially expandable stent-graft endoprosthesis is provided. The graft included in the stent-graft is a knitted tubular structure circumferentially disposed and securably attached to the stent. The knitted tubular structure has a knit pattern of interlacing yarns in an Atlas or a modified-Atlas pattern to provide greater than 150 percent longitudinal stretchability. A knitted tubular graft and a knitted medical fabric with greater than 150 percent longitudinal stretchability are also provided.

The invention relates to a method for positioning yarn by an embedded system, belonging to the technical field of textile processing. The method comprises the technical proposal that: on a drafting mechanism of a ring spinning frame, two chopped fiber rough yarns unreeled from a rough yarn bobbin enter a drafting zone respectively in parallel to be drafted by yarn guiding horns; two continuous yarns are fed from the rear end of a front roller, and join with the two crude yarn strands respectively at a front jaw; the two drafted crude yarn strands and the two continuous yarns are output from the front jaw, enter a twisting triangular zone to be twisted, and are wound on a spun yarn bobbin into yarn; according to different relative positions of the two crude yarn strands and the two continuous yarns, yarns with various structures can be formed. The method can realize that polycomponent yarns with a core-spun structure, a fasciated structure and a folded yarn like structure can be spinned on the ring spinning frame; the yarn structure can be accurately selected and determined and is closer, and yarns has more excellent hairiness, brute force and evenness; and spinning of special fiber yarns on the traditional spinning equipment can be realized so as to enlarge the range of spinning materials.
