Problems solved by technology

However, in this structure, since the warp tape or the weft tape has a lot of floating parts, it has the disadvantage of poor strength as a material for a grain storage bag with a heavy unit volume weight.
Also, there can be instances where grain gets caught in the buoyant portion of the bag, or gets caught on the metal workpiece

Embodiment Construction

[0015] Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings. figure 1 It is an example of the material weaving method adopted in the bag disclosed by the present invention, (1) is a structure diagram showing the relationship between the warp row and the weft row, and (2) and (3) respectively show the structure of the weaving method. In addition, in the structure diagrams (2) and (3), the structure of the column shown is shown by the arrow. The feature of this embodiment is that this special plain weave material is used in the bag. In the warp row and weft row, the composite tape of two warp tapes or weft tapes is used as a warp row at regular intervals. or weft columns. Here, the warp row is an element constituting the warp direction of the fabric weave, and is composed of one or more warp bands. Similarly, the weft column is the element that constitutes the weft direction of the fabric weave, and is composed of ...

Abstract

The invention provides a grain storage bag of high breathability and superior strength. A grain storage bag is of a plain weave structure constituted of longitudinal lines formed of respective one longitudinal belts, longitudinal lines formed of composite belts formed of a plurality of longitudinal belts overlapped together, latitudinal lines formed of respective one latitudinal belts and composite belts formed of a plurality of latitudinal belts overlapped together, all of which cross one another, and 1-3 longitudinal lines formed of composite belts formed of a plurality of longitudinal belts overlapped with one another are formed on every 3-20 longitudinal lines formed of respective one longitudinal belts and also 1-3 latitudinal lines formed of a plurality of latitudinal belts overlapped together are formed on every 3-20 latitudinal lines formed of respective one latitudinal belts.

Description

technical field [0001] The present invention relates to a bag with high air permeability and high strength for long-term storage of grains. Background technique [0002] Traditionally, grain storage bags made of plain weave fabrics have been used for long-term storage of grain. Grain storage bags made from plain weave fabrics are stronger than, for example, twill weave fabrics. image 3 Indicates the plain weave fabric currently used in this bag, (1) indicates the organization chart, and (2) indicates the structure chart. As shown in the figure, the plain weave fabric is composed of two adjacent warp rows and two adjacent weft rows that are identical at any point, and has good strength when used as a bag. . However, the warp and weft rows of the traditional plain weave fabric are arranged very closely, so when it is used as a grain storage bag, the air permeability is not good. [0003] on the other hand, Figure 4 represents an example of a twill fabric, with image 3 S...
