Description

[0001] The present invention relates to a coir net weaving machine,

The present invention relates to a corn net weaving machine, and more particularly, to a corn net weaving machine in which a plurality of warp yarns composed of coconut fiber yarns are fed in parallel at a predetermined interval in a warp fed section, And a binding yarn made of cotton yarn or synthetic fiber yarn is continuously supplied in a staggered state in a width corresponding to the thickness of the warp yarn so as to bind the warp yarn at an oblique position at a portion where the warp yarn and the weft yarn are crossed By joining the weft and the warp, the weaving condition of the cornet is not disturbed, so that the cornet without shape deformation is produced, and it is possible to effectively prevent the loss of soil when installed on the slope.

In general, the term "coir net" refers to a vegetation net consisting of a rough net structure in a plain weave crosswise and longitudinally crossed with natural coconut fruit fibers to accommodate a large number of receptacles, It has excellent durability and tensile strength, is excellent in heat retention and moisturizing, and is effective for germination and rooting of seeds, and is used to cover up the slope for preventing erosion or collapse.

In particular, the coreet has advantages of being easy to construct due to the conservative and light weight of natural fiber, and being eco-friendly and cheap. On the other hand, since the conventional cornet is woven by a natural-net netting structure by manual operation, the weft and the warp are easily disturbed even when receiving a small external force, the weft and the warp can not maintain a uniform gap, Soils are exposed as they are exposed, and when they are cut according to the length of the construction site, they are loosened (weft and slope) so that the loss rate at the construction site is considerably high, about 30%, and once rolled and united again There is a problem that it becomes impossible to use it because the rough lobe of the weft and weft and the rough lint of the warp are entangled with each other and become unfolded properly.

On the other hand, it is impossible to knit a net with a coarse surface and a non-uniform thickness of coconut fiber into a tissue having a loop (loop) rather than a simple mesh like the above. This is because when using a stiff coconut fiber yarn, This is because it is impossible to form a loop (loop) on the warp or weft.

Therefore, until now, such a cornet is woven by manual operation in a country where labor costs are low, so that supply and demand of the cornet are not smooth, and the quality is low, which is a problem as described above.
