Abstract

PROBLEM TO BE SOLVED: To provide a three-ply heat-insulating fabric.SOLUTION: A three-ply heat-insulating fabric includes: warp yarns including surface-layer warp yarns, second-layer warp yarns and binding warp yarns; and weft yarns including surface-layer weft yarns, second-layer weft yarns and embedded weft yarns. The surface-layer weft yarns and the second-layer weft yarns are bound with the binding warp yarns to form binding lines. The three-ply heat-insulating fabric is woven by two-ply weaving so that a surface-layer fabric and a second-layer fabric are formed based on each binding line. The embedded weft yarns are located between the surface-layer fabric and the second-layer fabric. Embedded warp yarns are further provided so as to be diagonal to the embedded weft yarns located in a hollow place formed between the surface-layer fabric and the second-layer fabric. The embedded weft yarns and the embedded warp yarns form nonwoven bulkiness-keeping parts near the binding lines. A plain weave part is located in the hollow place being inside one of the bulkiness-keeping parts and the other of the bulkiness-keeping parts. Thus, the three-ply heat-insulating fabric is formed of a three-ply woven fabric including the surface-layer fabric, the plain weave part and the second-layer fabric.

Description

  The present invention relates to a triple-woven warming fabric.

  In an agricultural greenhouse, in order to prevent the internal temperature from being dissipated to the outside, the layers of the greenhouse should be multi-layered so that the internal heat is not dissipated to the outside, or the heat insulation cover should be attached to the greenhouse. Position it outside and cover it at night and remove it during the day to prevent heat dissipation. In the case of the former, there is a problem that a lot of facility costs are required, and in the case of the latter, it takes time to put on and remove the heat insulation cover. There is a difficult problem.

  In some cases, a heat insulation cover constructed by sewing various kinds of fabrics is installed inside the greenhouse. However, there is a problem that the heat insulation power is reduced, the weight is heavy, and the use is inconvenient.

  In addition, while weaving the fabric with double weaving, the hollow portion is configured to be connected by tangent wires at equal intervals, and a warming fabric such as a weft of bulky material or a heat insulating material is located inside the hollow portion Developed and used for insulation curtains.
