摘要:
 染色材已广泛应用于竹窗帘、竹工艺品、竹地板和竹家具等领域。但是，染色材在应用过程中易受光照影响而褪色和变色，特别是紫外光。以4年生新鲜毛竹为试验材料，对常用染料染色材耐光性进行研究，并采用添加紫外线吸收剂、壳聚糖前处理竹材等方式探索提高染色竹材耐光性。结果表明，所选染料中，酸性染料染色材的耐光性最好，大多数染料的染色材在光照下明度变化最小，红绿轴色品指数变化最大；紫外线吸收剂或者壳聚糖前处理均能提高活性染料和酸性染料染色材的耐光性，后者的效果优于前者，对酸性染料，ΔE降到5以下，但2种方式对碱性染料和分散染料作用不明显；壳聚糖前处理与紫外线吸收剂相结合对染色材耐光性的作用较2种方式单独处理效果差。
Abstract:
 Dyed bamboo timber has been widely used as a material for curtains,crafts,floors and furniture.However,it is easy to lose its dyed color under light,especially under ultra-violet light.Taking the timber from 4-year-old fresh bamboo as material,the light fastness of the conventional dyes were examined,the methods of pre-treatment were investigated,such as adding ultra-violet absorbent in the dyes,or treating the timber with chitosan before dying.The results indicated that bamboo timber treated with acidic dyes showed the best light fastness.Among the three color parameters,the brightness of dyed bamboo after light irradiation varied slightly.The red-green axis chromaticity index exhibited the biggest variation.Both ultra-violet absorbent and chitosan pretreatment worked well in improving light fastness of reactive dyed bamboo and acid dyed bamboo.Chitosan showed better effect,and the value of ΔE decreased less than 5 when it was applied in acidic dyes.However,both showed little effect on basic dye and disperse dye.Chitosan pretreatment combined with ultra-violet absorbent is comparatively less effective than adopting only either one of both methods.
