Abstract: An elastic dope dyed yarn composite of two colors and process of manufacturing same is provided. The elastic dope dyed yarn composite of two colors includes an SDY having fibers being dope dyed, a POY drawn from dope dyed synthetic materials; and an elastic yarn. The SDY, the POY, and the elastic yarn are twisted together to form the elastic dope dyed yarn composite of two colors. The process is water saving and energy saving and causes no pollution. The elastic dope dyed yarn composite of two colors is light in weight and is capable of keeping warm, and has a high elasticity.

Abstract: An apparatus for manufacturing a heat retaining multi-ply textile includes an adhesive tank; a lower drive roll partially submerged in the tank; an upper drive roll including spaced, longitudinal projections wherein the projections contact the lower drive roll to bring the adhesive onto the projections; two opposite driven rolls; a first supply spool for moving a continuous upper textile sheet wherein the continuous upper textile sheet moves to have its underside contacted the longitudinal projections when passing the upper drive roll before moves to a joining line of the driven rolls; a second supply spool for moving a continuous lower textile sheet to the joining line of the driven rolls wherein the continuous lower and upper textile sheets are pressed toward each other to form compartments; and an oven for heating in order to produce the production. Down migration can be avoided.

Abstract: A yarn is provided with a hollow fiber including a plurality of filaments and one or more longitudinal voids between the filaments; and a heat retention fiber being a fiber for emitting infrared light, the heat retention fiber including a plurality of filaments each being capable of retaining heat, the filaments having nanoscale powder capable of emitting near and far infrared light uniformly formed therein. The hollow fiber and the heat retention fiber are twisted together to form a yarn having heat retention capability.

Abstract: A piece of clothing and a cloth structure thereof are provides. The cloth structure is used for making the piece of clothing and the piece of clothing is adapted to be worn by an object for keeping the object warm. The cloth structure comprises a surface layer, a thermal storage layer, and a thermal isolation layer. The thermal storage layer is configured to absorb heat radiated from the object when the piece of clothing is worn by the object. The thermal isolation layer is between the surface layer and the thermal storage layer and faces the thermal storage layer. The thermal isolation layer is configured to isolate heat from radiating out the thermal isolation layer.

Abstract: The present invention provides a heating apparatus which can be implemented as various articles for keeping human body warm, preventing from cold weather, insulating cold air, etc., e.g., warming clothes, electric blankets, hot compress pads, and curtains for insulating cold air. According to the invention, the heating apparatus includes a soft matrix, a metal yarn and a power supply. The metal yarn is integrated with the soft matrix to construct a loop pattern by a textile process, and has a first end line and a second end line. The first end line and the second end line of the metal yarn are detachably connected to the power supply. When the first end line and the second end line of the metal yarn both are connected to power supply, the power supply supplies the metal yarn with electric energy such that the metal yarn transfers the supplied electric energy into heat.
