A net for laver farming net and the manufacturing method thereof

摘要

The present invention relates to a net for a seaweed-style net that is manufactured to have a net of a certain dimension by weaving a net yarn made of synthetic resin, and more particularly, a first net yarn and a second net yarn having different coefficients of heat deformation, especially heat shrinkage. As the net is woven by treating it as a single net thread, each net forming the net is made to form a double net by the first and second net threads, and then the net is boiled and cooled through the net. By allowing the contraction and length deformation between the first and second net threads to be different from each other based on the knot, the net is pulled tightly in all directions or laid parallel to the sea level and installed across the depth of the water below the surface layer. If so, the first net yarns constituting each mesh are in an unfolded state, and the second net yarns constituting each mesh can provide a net structure that sags in the lower direction of the first net yarns. The production of farmed seaweed can be greatly increased by securing more sufficient and smooth communication of seawater through each net thread, as well as the first in the state that the net was first manufactured according to the usual net binding method. By using the difference in heat shrinkage deformation between the net yarn and the second net yarn, two net yarns with different lengths form a net provided at each side, so that easy production of the net and cost reduction can be achieved. It relates to a net for a net and a method of manufacturing the same.
