Artificial bionic blood vessel and preparation method
The present invention provides an artificial bionic blood vessel and a manufacturing method thereof. The artificial bionic blood vessel includes a three-layer-structured artificial bionic blood vessel body, where the three-layer structure of the artificial bionic blood vessel consists of a natural silk layer, a diluted liquid silica-gel layer and a weaved tube layer, the diluted liquid silica-gel layer is located on the inner side of the natural silk layer, the weaved tube layer is located on the outer side of the natural silk layer, and the weaved tube layer is made of catgut by weaving.

Tubular woven fabric
A tubular woven fabric is useful as a transport hose for a fluid or a powder, as a protective hose for linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. The tubular woven fabric includes warp yarns and weft yarns interwoven with each other, the tubular woven fabric having an outer diameter with a variation of within 10% along the warp direction and satisfying the formula:
(L2−L1)/L1≤0.1.

FLEXIBLE, ABRASION RESISTANT, WOVEN SLEEVE AND METHOD OF CONSTRUCTION THEREOF
A woven sleeve and method of construction are provided. The sleeve (10,10′) has a flexible, abrasion resistant elongate wall (12,12′) constructed from woven monofilament and/or multifilament yarns. The wall is configured to bound a cavity extending along a central axis (18) of the sleeve. The wall is woven with warp yarns (23) that extend generally parallel to the central axis of the sleeve and fill yarns (24) that extend circumferentially about the sleeve, generally transversely to the central axis. The warp yarns are bundled into individual, discrete groups (22), with each group (22) including a plurality of yarns (23) in side-by-side relation with one another, wherein each of the yarns (23) within the same discrete group (22) is interlaced over the same side of a common fill yarn (24).

WRAPPABLE END FRAY RESISTANT WOVEN PROTECTIVE TEXTILE SLEEVE AND METHOD OF CONSTRUCTION THEREOF
An end fray resistant textile sleeve includes an elongate wall having warp yarns extending generally parallel to a longitudinal central axis of the sleeve and fill yarns extending circumferentially about the sleeve. The warp yarns include at least two different types of yarns, with one of the types of warp yarns including activateable yarns and another of the types of yarns including non-activateable yarns. The activateable yarns can be provided as being activateable by at least one of heat, fluid and/or pressure, such that upon being activated, the yarns are caused to bond with the adjacent non-activateable warp yarns, as well as with the weft yarns with which they make contact. As such, the activateable yarns, upon being activated, become fixed with abutting warp yarns and weft yarns, thereby inhibiting end fray from resulting during a subsequent cold-cutting operation as well as in use.
