Abstract: Embodiments of the disclosure provide systems and methods for producing and using a plaited fabric comprising a low-melt yarn for adhering the fabric without a glue adhesive. According to one embodiment, a knitted fabric can comprise a first polymeric yarn of a first material, the first polymeric yarn forming a base of the knitted fabric, and a second polymeric yarn of a second material. The second material can be different from the first material and can have a lower melting temperature than the first material. The first polymeric yarn can be knitted with the second polymeric yarn to form the fabric. Upon an application of heat to the knitted fabric, the second polymeric yarn can form an adhesive and cohesive mechanical attachment to itself and form a tight-knit structural bond within the fabric without the use of a glue adhesive.

Abstract: An embroidery apparatus includes a main unit to be detachably mounted on a bed section of a sewing machine, a first translation mechanism that moves an embroidery frame holder with an embroidery frame mounted thereon in a first direction, a second translation mechanism that moves the first translation mechanism along an upper surface of the main unit in a second direction that orthogonally intersects the first direction, and an elevator mechanism that is supported by the second translation mechanism at opposite sides of the main unit and that raises and lowers the first translation mechanism. The embroidery apparatus is applicable to a sewing machine switchable between embroidery stitching and standard stitching. During standard stitching, the upper surface of the first translation mechanism is flush with the upper surface of the main unit, which enables both upper surfaces to be used as an auxiliary table.

The invention further relates to a method for manufacturing H-shaped prostheses for hernia repair from said base knit thus obtained and to the prostheses obtained therefrom.

Abstract: Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.
