碩士 === 台南應用科技大學 === 生活應用科學研究所 === 102 === In Taiwan, textile Chemicals &; dyeing and finishing industry environment, synthesis of dyeing process can be seen everywhere, easy to cause environmental pollution problems, in the global under the influence of green environmental protection, enhancement of environmental awareness and the people attach great importance to health of the body, so natural plant dyes rise again concerns, therefore more worthy the people to be in-depth discussion.This study of natural plant dyes onions and sappan woods to dye, and then extracted from its natural pigment, we changed the value of dye liquor and dyeing time trying to find out each of the suitable treatment of natural plants dyes on cotton and silk fibers, therefore, by the different mordant processed, the changes of color levels were detected、fastness of wash and rubbed were observed. The results that were as follows: 1.Onions were extracted the dye dyeing cotton and silk fibers mordant dyeing color variations after the treatment, in particular, in the cotton fiber concentration of 3%, especially the color difference maximum value of ferrous sulfate, which color difference value (K/S) is 11.294; In the silk fibers concentration of 3%, which color difference value (K/S) is 9.980. 2.Sappan Woods were extracted the dye dyeing cotton and silk fibers mordant dyeing color variations after the treatment, in particular, in the cotton fiber concentration of 3%, especially the color difference maximum value of copper acetate, which color difference value (K/S) is 23.540; In the silk fibers concentration of 3%, which color difference value (K/S) is 13.954. 3.After onions dye dyed cotton and silk fibers mordant treatment, which washing fastness regard tothe use of ferrous sulfate as a mordant washing fastness has been maintained above the level at 3-4.Rubbing fastness, regardless of dyeing cotton and silk fibers as time increases to 45 minutes its fastness to rubbing is not affected at about 4. 4.After Sappan woods dye dyed cotton and silk fibers mordant treatment, which washing fastness regard to the use of ferrous sulfate as a mordant, washing fastness are maintained by more than 30-90 minutes 3-4; another in terms of rubbing fastness, cotton and silk fibers dyed with time it increased to 45 minutes rubbing fastness were about 4-5. 5.The use of natural dyes dyed natural fibers, its dyed with natural colors and washing fastness, rubbing fastness, the effect of no less than the commonly used chemical dyes, are unique and combines the effectiveness of disinfection and pest control.
