Abstract:
Growing concern about the environmental effects of metal mordants and synthetic dyes is encouraging the use of bio-mordants and natural colorants. Cinnamon bark is a rich source of natural colorants such as cinnamaldehyde and tannins. The main purpose of this research was to study and compare the effect of bio-mordants versus metal mordants in terms of colorimetric parameters and color fastness properties of cinnamon bark on wool fibers. Accordingly, some bio-mordants, including date kernel, peppermint, banana peel, and artemisia, as well as some metal mordants like aluminum potassium sulphate and copper sulphate, were studied based on three conventional mordanting methods (pre-, meta-, and post-mordanting). The results indicated that the conjunction of metal mordants and polyphenolic bio-mordants with cinnamon colorants can create different hues and tones of brown. Also, the color produced by cinnamon in wool fibers has poor color fastness and low color strength. Overall, bio-mordants have presented good color properties, making the dyeing process eco-friendly and greener. Among the applied bio-mordants, peppermint has created the best color strength and color fastness.
摘要:
对金属媒染剂和合成染料的环境影响的日益关注鼓励使用生物媒染剂和天然着色剂。肉桂树皮是天然着色剂如肉桂醛和单宁的丰富来源。这项研究的主要目的是研究和比较生物媒染剂与金属媒染剂在肉桂树皮对羊毛纤维的比色参数和色牢度性能方面的影响。因此,一些生物媒染剂,包括日期内核,薄荷,香蕉皮,和蒿属,以及一些金属媒染剂,如硫酸铝钾和硫酸铜,基于三种常规媒染方法(预,元-,和媒染后)。结果表明,金属媒染剂和多酚生物媒染剂与肉桂着色剂的结合可以产生不同的棕色色调和色调。此外,肉桂在羊毛纤维中产生的颜色色牢度差,色强度低。总的来说,生物媒染剂具有良好的颜色特性,使染色过程环保和绿色。在应用的生物媒染剂中,薄荷创造了最好的颜色强度和色牢度。
