摘要

本文探討改變前處理鹼濃度對Lyocell纖維染色吸附性的影響。將Lyocell纖維先經過濃度5、10、15、20%鹼處理，再以三種不同結構的反應性染料進行等溫吸附染色，觀察其吸附行為的變化，並利用實驗數據探討經過處理後的纖維符合何種吸附方程式。由實驗結果得知，纖維吸附行為會隨著鹼濃度的增加而有所變化，而在5%-15%鹼濃度處理時纖維對染料的吸附量較未處理者為高，而不同的染料結構亦會影響染料的吸附行為。

This article discusses with caustic of different concentrations to process the density to the Lyocell fiber dyeing adsorbability influence. First passes through the Lyocell fiber with 5, 10, 15, 20% alkali processing, then carries on the adsorption by three kind of different structures reactivity dye, then observes its adsorption behavior if it fits, and conforms to what kind of adsorption equation. Knew by the experimental result that, the Lyocell fiber adsorption behavior can have the change along with the caustic concentrations increase. But when with the caustic concentrations 5%-15% processing the adsorbed by the fiber for is highest to the fiber, the dye adsorption behavior is not the same.
