The yarn base material has a first UV-curable outer layer formed from an ultraviolet-curing resin material, and a hollow cylindrical cutting die with a large number of microscopic grooves carved on the inner wall. The outer layer is made in the first step of injecting a resin liquid and irradiating the discharge side of the cutting die with ultraviolet rays to harden the ultraviolet curable resin flowing out from the cutting die into a thread shape. By passing it through the second ultraviolet curing resin liquid, etc.
It is produced in a second step in which a second ultraviolet curable resin liquid is applied to the surface and, after application, ultraviolet rays are irradiated thereto to obtain a cured translucent outer layer.

上記糸基材２′の断面形状は任意であるが、例
えば透明材料を用いて断面偏平な形状に成形すれ
ば、光反射面を広く出来ると共に分光効果も良く
出来ると云う利点がある。 Although the cross-sectional shape of the thread base material 2' is arbitrary, for example, if it is formed from a transparent material into a flat cross-sectional shape, there is an advantage that the light reflecting surface can be widened and the spectral effect can be improved.
この発明により得られた糸基材２′は、この様
に表面に微小な凹凸条が多数形成されているか

て微小な凹凸条を得る事が出来る。 The mold surface 121 of the mold plate 12 may be formed by a photo-etching method or a processing method using a laser beam. For example, when using a laser beam, approximately 600 grooves with a width of 1 mm are carved on an aluminum plate. Therefore, it is possible to obtain extremely fine unevenness on the yarn base material 2'.

い。 As mentioned above, the yarn base material 2' produced by the method of the present invention has minute unevenness lines on its outer surface, and these unevenness lines cause diffuse reflection and spectroscopy of light, but the above unevenness lines are extremely minute. Because of this, it is unavoidable that it is easily buried and lost due to dust and grease.

本発明方法はこの様なものであるから、下記効
果を得る事が出来る。 Since the method of the present invention is as described above, the following effects can be obtained.
第１に、紫外線硬化樹脂は溶剤を含まないから
硬化過程で環境を汚染する事がない。 First, since UV-curable resins do not contain solvents, they do not pollute the environment during the curing process.
第２に、紫外線硬化樹脂は硬化速度が極めて早
いから、糸基材２′の凹凸条を良好に形成出来る
と共に、製造速度が早く大量生産が出来る。 Secondly, since the ultraviolet curable resin has an extremely fast curing speed, it is possible to form the concave and convex stripes on the thread base material 2' well, and the manufacturing speed is fast, allowing for mass production.
第３に、糸基材２′の上に外層４が形成され、
これによつて凹凸条が被覆されるから凹凸条が塵
埃や脂垢等の外部汚染粒子によつて埋没される事
を防止出来、従つて変光効果を永続的に維持出来
る。 Third, an outer layer 4 is formed on the yarn base material 2';
Since the uneven stripes are thereby covered, it is possible to prevent the uneven stripes from being buried by external contaminant particles such as dust and grease, and thus the light-changing effect can be maintained permanently.
第４に、糸基材２′上に形成する外層４が、溶
剤を含まない紫外線硬化樹脂であるため、外層形
成によつて凹凸条が侵蝕される虞れがない。 Fourthly, since the outer layer 4 formed on the thread base material 2' is made of an ultraviolet curing resin that does not contain a solvent, there is no risk that the uneven stripes will be eroded by the formation of the outer layer.
第５に、糸基材２′と外層４との光屈折率が異
なるから、変光効果が格段に良好である。 Fifth, since the fiber base material 2' and the outer layer 4 have different optical refractive indexes, the light-changing effect is much better.
