由於奈米科技進步，奈米材料應用在產業上具有多功能的性質。本研究使用不同波美度的色料餵食家蠶，以找出最佳的彩色蠶繭色澤，並研究其如何影響家蠶所結出的蠶繭及色料附著在蠶繭上的絲。同時對色料附著的蠶繭進行水洗、光照、微結構的觀察，以試圖找出色料與波美度之最佳組合參數。由本實驗結果得知，利用奈米色料溶液60 ml，在紅色：1.048、藍：1.058、黃：1.039 的參數下，混合飼料30g，可獲得最佳的彩色蠶繭結繭成功率、均勻度較佳、耐褪色與耐洗滌等優點，並且可獲得表面結構光滑且較細的絲徑，約為19.87μm。相對的，一般色料粒徑為微米級，色彩度優於奈米色料，但表面結構較奈米色料粗糙且線徑較粗，約為21.51μm，易於褪色及不耐洗滌。 Because of the great progress of nano-technology, it has the quality of multi-functions to make use of nano-materials on industrial property. The purpose of this study is to find the best colored silkworm cocoons by mixing different consistency of pigments to feed silkworms. At the same time, this study wished to explore how the different consistency of pigments influenced the silkworm cocoons that the silkworms produced. Besides, in order to find the better association between pigments and Baume degrees, this study exposed the cocoons under different lights, washed with different detergents and take observations of micro-structure of the cocoons. The results of this study are as follows: using the nano-pigments 60 ml in different density, that is, red:1.048, blue:1.058, and yellow:1.039, then mixed them with silkworms’ forage 30g , in this way, best successful ratio to get colored cocoons, desired high visual effects in color, well distribution, long duration and strong resistance to detergents agents are obtained. In addition, we can still get glossy appearance and fine cocoons; the wire diameter is about the size of 19.87μm. On contrast, feeding with the ordinary pigments, the degree of colored silk is better than feeding with the nano-pigments, but the appearance of cocoons are rough and the wire diameter is about the size of 21.51μm.
