The present invention relates to a kind of three-dimensional superbright light DTY fiber and its processing method, its fibre section is imitative trilobal；Three blade end ports of imitative trilobal are respectively provided with the triangle of evagination, and the triangle of evagination for equilateral triangle, and the length of side of equilateral triangle is identical with the width of the three of trilobal blades.The triangle that evagination is arranged more shows the function of superbright light, while the length of triangle, width ratio difference cause the refractive power reflectance of fiber different, the light performance diversity of cloth cover.Therefore it is required that evagination triangle is approximate equilateral triangle, it is ensured that fiber refractive power reflectance.The present invention has the good superbright light polyester DTY fibers of aspects such as gloss is bright-coloured, soft, drapability is good, the comfortable flexibility of light polyester filament for avoiding present production is poor, the outer surface of strand is poor to the refraction of light, reflecting effect, dull, and lousiness is more, easily break end, the fabric being made into lacks flexibility and beautiful property. |
