Abstract: To provide a thermoforming method for obtaining a thermoformed article that exhibits excellent abrasion resistance at melt-bonded portions, and excellent adhesive strength between woven fabrics or to another kind of article. Polyethylene having a melt flow rate, measured under conditions of a temperature of 280° C. and a load of 2.16 kg, of 10 to 15 g/10 min and polyethylene terephthalate are prepared. By a conjugate melt spinning method using the polyethylene terephthalate as a core component and the polyethylene as a sheath component, multi-filament yarn in which core-sheath composite filaments having a core component:sheath component mass ratio of 1 to 4:1 are bundled is obtained. A product of filaments is obtained by weaving, knitting, braiding or winding using the multi-filament yarn. Thermoforming of the product of filaments is carried out by heating the product of filaments to melt the polyethylene, thereby melt-bonding the core-sheath composite filaments to each other, with the polyethylene terephthalate retaining its initial filament form.

Abstract: Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.
