Disclosed is a method of strengthening existing structures containing the following steps. An existing structure made of concrete, steel, timber, masonry to be reinforced and a reinforcing sheet are provided, where the reinforcing sheet contains an alternating arrangement of reinforcement zones and slitting zones. The reinforcement zones contain unidirectional strengthening fibers in the warp direction of the reinforcement sheet and the slitting zones have an absence of strengthening fibers. The reinforcement sheet is slit through the slitting zones and the reinforcement zones are adhered to the existing structure.

An exemplary elongated elevator load bearing member of a traction elevator system includes a plurality of tension elements. A plurality of weave fibers transverse to the tension elements are woven with the tension elements. The weave fibers define at least one traction surface of the load bearing member.

Disclosed herein are a loom for weaving a fabric with two types of tissue, a shoe upper woven using the loom, and a shoe including such a shoe upper. The loom includes a first heddle stack formed by arranging a plurality of first heddles in one or more rows, and a second heddle stack formed by arranging a plurality of second heddles in one or more rows, the second heddles being different in kind from the first heddles. The first heddle stack and the second heddle stack are sequentially arranged in a warp feeding direction.

The present disclosure relates to a shoe upper including a stretchable area and a non-stretchable area. The shoe upper is woven by combining a warp yarn and a weft yarn, the weft yarn includes a first weft yarn, which is a stretchable yarn, and a second weft yarn, which is a normal yarn, the first and second weft yarns being alternately arranged next to each other, in the stretchable and the non-stretchable area, the shoe upper is woven with a leno weave and a plain weave in which the first weft yarn and the second weft yarn each are combined to the warp yarn, and the number of weave points of the warp yarn and the second weft yarn is larger in the non-stretchable area than in the stretchable area.

Each of upper surface side warps arranged vertically with lower surface side warps in pairs has a common weaving pattern excluding binding wefts. Binding warps constitute at least one of two warps vertically arranged forming pairs. In the pairs formed by the binding warps and the warps arranged vertically with the binding warps, the warps complement each other to form a weaving pattern for one upper surface side warp and a weaving pattern for one lower surface side warp, respectively, The upper surface side warps and the binding warps are interwoven with the upper surface side wefts to form an upper surface side fabric formed in a predetermined weaving pattern for each warp row. The lower surface side warps and the binding warps are interwoven with the lower surface side wefts to form a lower surface side fabric formed in a predetermined weaving pattern for each warp row.

The wefts include: binding wefts that bind the upper surface side fabric and the lower surface side fabric; upper surface side wefts that form a part of the upper surface side fabric; and lower surface side wefts that form a part of the lower surface side fabric. The warps include: binding warps that bind the upper surface side fabric and the lower surface side fabric; upper surface side warps that are interwoven with the upper surface side wefts without being interwoven with the lower surface side wefts so as to form a part of the upper surface side fabric; and lower surface side warps that are interwoven with the lower surface side wefts without being interwoven with the upper surface side wefts so as to form a part of the lower surface side fabric.

The present disclosure provides a shoe upper woven using a warp yarn and a weft yarn, having the weft yarn formed so that a first weft yarn which is a high-stretch yarn and the second weft which is a regular yarn overlap each other, and including a three-dimensional pattern region in which the first weft yarn is disposed on a rear surface and the second weft yarn is disposed on a surface to form the three-dimensional pattern on the surface.

An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame having an inflow end, an outflow end, and a longitudinal axis. A leaflet structure is positioned within the frame and secured thereto, and a sealing element is secured to the frame. The sealing element includes a first woven portion extending circumferentially around the frame. The first woven portion includes a plurality of interwoven filaments. The sealing element further includes a second woven portion extending circumferentially around the frame and spaced apart from the first woven portion along the longitudinal axis of the frame. At least a portion of the filaments exit the weave of the first woven portion and form loops extending radially outwardly from the frame.

Disclosed is a multi-nested twisting loom, a method, a fabric weave, and an upper. The multi-nested twisting loom includes several nested twisting heald sets. The nested twisting heald sets are sequentially arranged along a weft direction on the loom. Each nested twisting heald set includes a second-level twisting heald at a front end of a warp advancing direction and a first-level twisting heald at a rear end. The second-level twisting heald is composed of a single twisting heald. The first-level twisting heald is composed of m twisting healds, where m is greater than 1. The leno weave in the present disclosure is composed of different levels of twisted areas, which increases the variety of leno weaves. Breathable holes with different sizes are formed between different levels of twisted areas, which better fit various parts of the human body and meet the different breathable needs of different
