PURPOSE:To obtain a fiber structure having excellent durability and color anisotropy by bonding a copper oxide to a sheath-core type conjugate yarn structure and heat-treating, and the producing method therefor. CONSTITUTION:In a fiber structure having color anisotropy obtained by bonding a thin film of a copper oxide having 100-5,000Angstrom film thickness to the surface of constituent yarn of a fiber structure comprising conjugate yarn wherein two different components are bonded to a sheath-core type, a polymer of the sheath component has a lower melting point than a polymer of the core component and a ratio of sectional area of the core component/the sheath component is >=2/1. The thin film of the copper oxide has a gradient of oxidation degree from high degree of oxidation on the surface to low degree of oxidation at the constituent yarn side and a specific interference color corresponding to the film thickness. |
