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: The present invention relates to a method and an apparatus for evaluating the phase changing function of fabric. First, a fabric with phase changing material to be evaluated its phase changing function is provided and positioned between a body temperature device and an environment temperature device. Then, said fabric is heated by a controller through two control means for simulating the temperature of a human body and nature environment respectively, wherein said controller is connected with said body temperature device and with said environment temperature device separately with two control signal cables for controlling temperature, and said fabric generates a body thermal signal and an environment thermal signal. A record device is provided for receiving said body thermal signal and said environment thermal signal through at least a feedback signal cables.
