Embodiment 1

[0181] Eight DYNEEMA 150 d / 140 F (TOYOBO Co. Ltd.) were wound and woven into nucleated yarns with a braiding machine. The core yarn is dip-coated with acrylate resin (VONCOAT 3750 of DAINIPPON INK AND CHEMICALS Inc.), fed into the kiln at a feeding roller speed of 150m / min and heated to 170°C, and then coiled at a winding speed of 345m / min Winding, the yarn of the present invention is produced like this.

Embodiment 2

[0183] Four DYNEEMA 150d / 140 F (TOYOBO Co. Ltd.) as side yarns and THERMOLUX P0105 300d (LUXILON)) as yarn cores were woven at right angles to the nucleated yarns with a knitting machine. The core yarn is dip-coated with acrylate resin (VONCOAT3750 of DAINIPPON INK AND CHEMICALS Inc.), fed into the kiln at a feeding roller speed of 100m / min and heated to 160°C, and then wound at a winding speed of 250m / min , thus producing the yarn of the present invention.

Embodiment 3

[0185] Monofilaments were produced using high specific gravity nylon resin (MCTS00005 flake, specific gravity = 3: KANEBO GOHSEN) containing nylon 6 / 66 (NOVAMID 2030J flake, MITSUBISHI CHEMICAL) and metal (tungsten, specific gravity = 19.3) under the following conditions. That is, the high specific gravity nylon resin was supplied to an extruder with a bore diameter of 40 mm and melted at 270°C, spun from a spinneret with a bore diameter of 2.1 mm and cooled in a water bath at 50°C. Then, the undrawn yarn was stretched under conditions of wet heating at 95°C and dry heating at 220°C through two steps at a draw ratio of 4.5. A monofilament with a diameter of 0.515 mm was produced by relaxation-heat treatment in which it was drawn at a temperature of 225° C. at a draw ratio of 0.98.

[0186] Eight pieces of DYNEEMA 150 d / 140 F (TOYOBO Co. Ltd.) were wound and woven around a monofilament as a yarn core to obtain a yarn having a core-sheath structure. These core yarns were dip-co...

Abstract

This invention is to provide yarns including fishing lines which contain ultra-high molecular weight polyethylene filaments with low elongation rate, adjustable specific gravity and excellent abrasion resistance, and to provide a method for manufacturing the same.

Description

technical field [0001] The present invention relates to yarns with very low elongation comprising ultra-high molecular weight polyethylene filaments, and to a method for their manufacture. Background technique [0002] Recently, with the high development of fishing technology, high-performance fishing lines have been demanded. One of the high performance is low elongation. The smaller the elongation, the more precisely one can feel the point when the fish bites, which directly reflects a good fishing result. [0003] However, the lower elongation of the yarn creates a problem of decreased abrasion resistance. That is, reducing the elongation of the yarn leads to generation of fibrils, and thus reduces abrasion resistance. [0004] Additionally, fishing line typically has a specific gravity inherent to the material. There has been a demand in the market to finely vary the specific gravity of the thread according to climatic and / or tidal conditions, not limited to the spec...
