Colored yarn object, process for producing the same, and fishing line

A yarn object colored with a colorant, comprising a core yarn 2 colored with at least one predetermined colorant and an outer-layer yarn 3 comprising a transparent or semi-transparent filament made of ultra-high-molecular-weight polyethylene,

• wherein:
• the core yarn 2 comprises a plurality of filaments made of ultra-high-molecular-weight polyethylene,
• the outer-layer yarn 3 is disposed on a periphery of the core yarn 2 in such a manner that the outer-layer yarn 3 entirely covers the core yarn 2, the core yarn 2 is prevented from contacting with other objects and a space 4 is not formed between adjacent windings or braids of the outer-layer yarn 3,
• the core yarn 2 and the outer-layer yarn 3 are subjected to a heat treatment followed by a drawing treatment, and
• the at least one predetermined colorant applied to the core yarn 2 is externally visible through the outer-layer yarn 3.
