Abstract
A braid including a core part and a sheath part, wherein the core part includes a high strength fiber (a) having a fineness of 300 to 4,000 dtex and a tensile strength of 12 cN/dtex or more, and the sheath part includes a colored synthetic fiber (b) having a fineness of 60 to 1,000 dtex and a tensile strength of less than 12 cN/dtex. A volume ratio [av/bv] of the high strength fiber (a) constituting the core part to the colored synthetic fiber (b) constituting the sheath part is from 73/27 to 40/60. The sheath part has a braid-like structure.
Claims18
A braid comprising:
- a core part comprising a high strength fiber (a) having a fineness of 300 to 4,000 dtex and a tensile strength of 12 cN/dtex or more;
- and
- a sheath part comprising a synthetic fiber (b) having a fineness of 60 to 1,000 dtex and a tensile strength of less than 12 cN/dtex,
- wherein the synthetic fiber (b) is colored such that the sheath part blocks light reaching the core part,
- a volume ratio [av/bV] of the high strength fiber (a) constituting the core part to the colored synthetic fiber (b) constituting the sheath part is in a range of 73/27 to 40/60, and
- the sheath part has a braid-like structure.
