    We propose a novel method “embedded and pull-out test” to quantitively evaluate adhesion in plated fiber. In the method, the plating fiber is embedded only some length at one end into resin, and the other end of fiber is pulled to conduct pull-out test. For the samples whose plating exfoliated without fiber breaking, we measure the maximum load in the pullout test and the length of plating exfoliation. The plating adhesion can be evaluated quantitatively as interface stress from the maximum load and the exfoliated length. Using the proposed method, we examined plating adhesion of copper plating high-strength polyarylate fibers which were plated at the two different processing company. As a result, it is confirmed that the maximum load and exfoliated length have a mostly proportional relation, and the plating adhesion is able to be evaluated quantitatively as interface stress. The plating adhesion of two samples which did not show any difference in the peel test can be confirmed that there was about two times difference in this method.

    The process of weaving three-dimensional spacer fabrics on double-shed rapier looms is analyzed. In order to solve the tension control problem of the longitudinal warp non-closed shed, a brief opening model of heald frame is constructed in this paper, and the opening tension is analyzed. The results show that the longitudinal warp tension has a compound function relationship with the length of the rear shed of the loom. When the distance of the front shed and the height of the ground warp in the weaving process are known, the guide bar position of the warp drop frame can be effectively measured by the ratio of the ground warp opening elongation and the ground warp length. In this way, the tension during weaving of multiple sets of warp yarns is uniform.
