摘　　要：针对天然彩棉在后整理加工中金属离子等因素使其颜色发生变化的问题,研究了天然彩棉在不同温度、不同pH值溶液、石油醚预处理以及在金属离子处理液中颜色的变化,并制定合理的加工工艺。结果表明:当温度低于80℃时,天然彩棉颜色无太大变化,当温度高于80℃时,随温度的增加,天然彩棉颜色发生明显变化;当pH值小于7时,天然彩棉的颜色随pH值减小而逐渐变浅,当pH值大于7时,天然彩棉的颜色随pH值增大而逐渐变深;经石油醚预处理后天然彩棉的颜色比未经石油醚预处理的更为稳定;Fe^2+、Fe^3+、Cu^2+等金属离子均对天然彩棉颜色有影响,其中Fe^3+对天然彩棉颜色的影响最大。The color of the natural colored cotton has been found to change to a certain extent during the finishing treatment.The color changes of natural colored cotton under different temperatures,solutions with different pH values,petroleum ether pretreatment and metal ion treatment solution were studied in order to formulate a reasonable processing technology.The results show that when the temperature is lower than 80℃,the color of natural colored cotton keeps better.When the temperature is higher than 80℃,the color of natural colored cotton changes obviously with the increase of temperature.When the pH value is less than 7,the color of natural colored cotton becomes paler with the pH value decreases,and when the pH value is greater than 7,the color of natural colored cotton becomes more intensive with the pH value increases.The color of natural colored cotton treated with petroleum ether appears to be more stable than that of colored cotton treated without petroleum ether.Fe^2+,Fe^3+,Cu^2+and other metal ions all have influence on the color of colored cotton,among which Fe^3+has the greatest influence on the color of colored cotton.
