天然染料的提取及在扎染中的应用

天然染料的提取及在扎染的应用摘要天然染料是一种由植物，动物，矿物等天然物质中提取的产物，其中，植物靛蓝染料是天然染料中最受欢迎的种类之一。它具有色泽艳丽，色牢度高且抗菌，抗炎等优点，广泛应用于各类纺织品甚至是食品，药品当中。靛蓝染色在扎染工艺领域也有着长久的发展历史，研究靛蓝扎染这种工艺，可以让我们更直观的了解到这种传统非遗文化传承的价值和意义。本文采用植物靛蓝作为染料，结合传统的扎染工艺，通过对染色过程中不同条件的控制和不同的扎染技法的实践，研究了植物靛蓝在扎染中的应用效果。采用测试配色仪对棉织物样品的KS值进行测定，通过洗涤和摩擦的标准化方法，测定其色牢度。实验结果表明，植物靛蓝多次染色后的纺织品可达到较高的和KS值色牢度，且扎染后的织物具有独特的纹理和色彩效果。这种染色方式不仅符合现代消费者对绿色环保的需求，而且能够传承和发扬传统工艺，展现其独特的文化价值。关键词：植物靛蓝扎染KS值色牢度Extraction of natural dyes and their application in tie-dyeingAbstractNatural dyes are products extracted from natural substances such as plants,animals,andminerals.Among them,indigo dye from plants is one of the most popular types of natural dyes.It has the advantages of bright color,high color fastness,and antibacterial and anti-inflammatoryproperties,and is widely used in various textiles,even in food and medicine.Indigo dyeing alsohas a long history of development in the field of tie-dyeing craft.Studying this craft can help usbetter understand the value and significance of this traditional intangible cultural heritage.This article uses plant indigo as a dye and combines traditional tie-dyeing techniques tostudy the application of plant indigo in tie-dyeing through the control of different conditions andthe practice of different tie-dyeing techniques during the dyeing process.The K/S value of cottonfabric samples was measured using a colorimeter,and their color fastness was determinedthrough standardized methods of washing and rubbing.The experimental results showed that thetextile dyed with plant indigo after multiple dyeing could achieve high K/S value and colorfastness,and the fabric had a unique texture and color effect after tie-dyeing.This dyeing methodnot only meets the modern consumer's demand for green and environmental protection but alsocan inherit and carry forward traditional crafts,demonstrating its unique cultural value.Keywords:Plant indigo:Tie-dyeing:K/S value;Color fastness目录摘要。Abstract....第一章前言1.1选题背景及研究意义…1.2靛蓝扎染的历史与应用1.2.1靛蓝染色的历史1.2.2扎染的历史.21.2.3靛蓝扎染的应用1.3实验原理1.3.1植物靛蓝的提取及染色机理041.3.1靛蓝染色工艺的改进历程1.3.2扎染工艺机理」.6第二章实验部分…。2.1实验试剂材料及仪器2.1.1实验试剂与材料2.1.2实验仪器2.2实验方法2.2.1植物靛蓝的提取.82.2.2植物靛蓝的染色82.3测试方法.102.3.1K/S值测试..102.3.2染色牢度测试..102.4扎染设计..102.4.1扎染前准备.102.4.2扎染技法实践.112.4.3扎染在服饰品中的应用实践…12
