  • Publication number: 20230349080
    Abstract: A sticky spacer fabric and its manufacturing method, the sticky spacer fabric includes a first outer layer, an intermediate layer, and a second outer layer, with the intermediate layer interposed between the first and second outer layers and interknit with them. At least one of the first and second outer layers has a sticky surface formed by thermoplastic elastic yarns knitted together, with the sticky surface being exposed partially or fully to the outside of the first or second outer layer. The sticky spacer fabric of the present invention is suitable for making clothes that closely contact the wearer’s skin and can be used to replace invisible underwear or silica gel underwear. In addition to having slip-proofness and adhesion properties, the sticky spacer fabric of the present invention also provides better breathability, heat or moisture permeability, good comfort, excellent stretch and resilience, and environmental friendliness.

  • Publication number: 20210086470
    Abstract: A spacer fabric having removable yarns is provided. The spacer fabric includes a first fabric layer, a second fabric layer, and a middle fabric layer. The first fabric layer is formed of general-purpose yarns and the removable yarns wherein the general-purpose yarns and the removable yarns are arranged to a weft-knitted loop construction according to a predetermined pattern The middle fabric layer is formed of wave-like fibers interlocked with the first fabric layer and the second fabric layer. The predetermined pattern appears on the first fabric layer after the removable yarns are removed.

  • Publication number: 20200307150
    Abstract: A garment is provided with at least a portion of cloth being made of a fabric structure. According to the present invention, the fabric structure comprises an outer fabric layer, an inner fabric layer and a central fabric layer. The outer fabric layer is knitted with nylon-contained fibers, and the inner fabric layer is knitted with PU-dominated sticky fibers. The central fabric layer is interposed between the outer fabric layer and the inner fabric layer and knitted with wave-like fibers. The wave-like fibers are intertwined with the nylon-contained fibers and the PU-dominated sticky fibers respectively. Therefore, the inner fabric layer is in close contact with the skin of the user to provide mild stickiness.
