Dyeing of Sponge Gourd by Different Methods

ABSTRACT

Sponge gourd is one of the natural fibers, and its products are biodegradable and sustainable. Modifying the surface of fibers with ultrasonic energy can be improving their dyeability, opening up fibers structure and the mass transfer from one medium to another. The aim of this work is to investigate the possibilities of sponge gourd dyeing by reactive dyes with conventional methods and under the ultrasonic power. The color yields, penetration behavior and fastness properties of dyed fibers by different methods were compared to each other. Using ultrasonic energy was increased dye uptake results by 16% than the conventional method (approx. 80% to 93%). The fastness results in washing and dry/wet rubbing were up to 4 gray scale level. The ultrasonic power seems promising since it enhances color yields and reduces process time.

摘要

冬瓜是一种天然纤维， 其产品具有生物可降解性和可持续性.利用超声波能量对纤维表面进行改性，可以提高纤维的可染性，改善纤维结构，提高纤维在不同介质中的传质性能. 本研究的目的是探讨在超声波功率下，用常规方法对活性染料进行丝瓜染色的可能性. 比较了不同染色方法对纤维的显色率、渗透性能和染色牢度的影响. 使用超声能量比传统方法（约80-93%）提高染料吸收率16%. 耐洗涤和干/湿摩擦的染色牢度可达4个灰度级. 超声功率似乎很有前途，因为它提高了颜色的产量，缩短了加工时间.
