彩色丝

天然彩色丝是指蚕本身吐出的丝就含有色素。

The natural color of silkworm is a kind of silkworm which spit out the colorful silk itself .

用彩色丝制成的纺织品，无需漂白、印染处理，就具有自然的色泽，且织物更加柔软、富有弹性。

Textiles made of silk color , without bleaching , dyeing and printing processing , it has a natural color , and fabric more soft and elastic .

本文还对固胶牢度进行检测，结果发现：原有的检测方法不适合于固胶彩色丝，它们条件要么太苛刻，要么比较温和。

The results show that the original methods are not suitable for detection fastness of sericin fixation color silk . They need either too harsh condition or relatively mild .

方法：用MTT比色法评价彩色弓丝和未染色弓丝和托槽的细胞毒性，并用流式细胞仪法（FCM）检测细胞群落的DNA增殖指数。

Method : Cytotoxicity of colored and unstained orthodontic bracket and wire against human gingival fibroblast ( HGF ) was investigated with MTT assays and the cell DNA proliferation index ( PI ) of cell groups was assessed through flow cytometry .

结论这种彩色弓丝和托槽具有良好的细胞相容性。

Conclusion The colored orthodontic wire and bracket had good biocompatibility .
