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.본 발명은 합성수지 재질의 그물실을 엮어 일정한 치수의 그물코를 가지도록 제작되는 김양식망용 그물망에 관한 것으로서, 더욱 상세하게는 열변형계수, 특히 열수축계수가 서로 다르게 되는 제 1그물실과 제 2그물실을 한 가닥의 그물실로 취급하여 그물망을 엮어냄에 따라, 그물망을 이루는 각각의 그물코가 제 1그물실과 제 2그물실에 의한 2중 그물코를 이루도록 한 다음, 해당 그물망의 보일링과 냉각처리를 거쳐 그물매듭을 기준으로 하는 제 1그물실과 제 2그물실간의 수축 및 길이변형이 서로 다르게 발현되도록 함으로서, 상기 그물망을 사방으로 팽팽하게 당기거나, 해수면과 평행하게 눕혀진 상태로 표층 아래의 수심에 걸쳐 설치되는 경우 각각의 그물코를 이루는 제 1그물실은 펼쳐진 상태가 되고, 각각의 그물코를 이루는 제 2그물실은 제 1그물실의 하부
