A carpet pad includes a top hook layer and a bottom anti-slip layer. An upper surface of the hook layer is provided with protruding monofilaments in a bent shape. Top ends of the protruding monofilaments are provided with bumps formed by melting/softening and then cooling the protruding monofilaments. The protruding monofilaments on the hook layer are heat-treated to make their top ends melted/softened into the small bumps. The heat-treated protruding monofilaments have a certain degree of curvature and inclination, and thus can firmly hook with various carpets above and provide a large friction force, in particular in a vertical direction. The length and density of the protruding monofilaments are reasonably designed to make the protruding monofilaments well hook and lock with the carpet above. In addition, the protruding monofilaments touch soft, and the bumps are not prickly.

Provided is a method for manufacturing a printing sheet for digital printing using a screen yarn woven with a polyester monofilament capable of directly outputting (printing) by a digital printing machine (a digital inkjet plotter, a printer, etc.) and a printing sheet for digital printing according to the same, and more particularly, to a method for manufacturing a printing sheet for digital printing using a screen yarn woven with a polyester monofilament by a post-processing including first and second coating processes, a compression process, a drying process, a side cutting process, and a winding process and a printing sheet for digital printing manufactured by the same.

A method for forming a copolyester material includes preparing a solution of monomers, applying a polymerization to form a copolyester having a low melting point, spinning the copolyester into fiber threads to form a copolyester fiber, weaving or knitting the copolyester fiber with a common fiber to form a composite fiber having a sheet shape, cutting the composite fiber to form a determined shape, applying a hot-press process on the composite fiber under a temperature of about 120 C. to 200 C., to release tackiness of the copolyester, so that the copolyester fiber and the common fiber are bonded tightly and closely, and forming a tough film on a surface of the composite fiber by the copolyester, so that the composite fiber has functions of stiffness and abrasion resistance by the tough film.

Method and apparatus for producing ultra-smooth knitted fabric using hairy yarn belong to a technical field of textile. Yarn is false-twisted in a rotary holding form, for rotating the yarn stem on an ironing face. Meanwhile, a directional hairiness stretching device directionally ejects a steam flow towards the yarn, for reversely and orderly pre-wrapping hairiness on the rotating stem of the yarn, which avoids the yarn imperfection occurrence as the hairiness randomly or vertically wrapping onto the yarn stem. A vortex hair-wrapping device is used, so as to reversely wrap all the rest hairiness on the stem of the yarn, wherein a wrapping direction is opposite to a yarn moving direction for increasing difficulty of pulling out the wrapped hairiness during weft knitting, and increasing hair-wrapping tightness and fastness. The ultra-smooth yarn treatment apparatus is reasonably constructed and easily operated, which facilitates wide application.

Apparatus and methods for delivering a heated fluid. The apparatus includes at least a preheat zone, an expansion zone, and an expanded zone comprising a plurality of trim heaters, at least one fluid flow-distribution sheet, and an outlet. The apparatus may be used for delivering the heated fluid onto a moving fluid-permeable substrate.
