Document Type and Number:

WIPO Patent Application WO/2019/044386

Kind Code:

A1

Abstract:

The present invention provides a mesh sheet and a container bag which, when formed into a three-dimensional shape with a curved surface, have the ability to retain and recover said shape, and which are less prone to wrinkling, and the like.　Warp threads 1a and weft threads 1b are formed by arranging first fibers 2 which comprise a single component and second fibers 3 which have at least a double-layer structure of a core portion and a sheath portion covering the surface of the core portion and in which the melting point of the component forming the sheath portion is at least 20°C lower than whichever is lower from among the melting point of the component forming the core portion and the melting point of the first fibers 2. At least the second fibers 3 are provided to both the warp threads 1a and the weft threads 1b, and the interlacing sections of the second fibers 3 constituting the warp threads 1a and the second fibers 3 constituting the weft threads 1b are thermally bonded. The percentage of thermally bonded interlacing sections of second fibers 3, 3 among all of the interlacing sections of the warp threads 1a and the weft threads 1b is 10% to 45%.
