Abstract: Disclosed is a force applying device for orthodontic treatment being elastically expandable and configured to generate a restoring force as an orthodontic force for an orthodontic treatment when compressed. The force applying device comprises a first element and a second element capable of moving relative to each other along a first axis. The force applying device for orthodontic treatment is compressed when the first and second elements move towards each other along the first axis. A first arm extends laterally from a first end of the first element away from the second element. A first connecting part of a first connector is fitted over the first arm. A second connecting part of the first connector is to be fitted over a button fixed on a first jaw to connect the first element to the first jaw. Both the first and the second connecting parts are toroidal in shape.

Abstract: An industrial fabric is a web woven from warp yarns made of monofilaments and weft yarns made of monofilaments. The warp yarns are of a double-layer structure. One of warp yarn basic units comprises four sub-units, two sub-units being located on an upper layer, the other two sub-units being located on a lower layer. The warp yarns on the upper layer and the warp yarns on the lower layer are vertically overlapped, wherein at least two sub-units comprise two parallel narrow warp yarns. Upper warp yarns and lower warp yarns are identical in texture structure, or one surface is identical to the other surface after rotating by 180 degrees. The industrial fabric is stable in structure and good in overall consistency. The upper surface is good in flatness, the surface is free from defects, and the quality and intensity of the fabric are improved.
