Investigation on Dyeing Performance of Basic and Reactive Dyes Concerning Jute Fiber Dyeing

ABSTRACT

This paper includes the investigation on the dyeing performance of reactive and basic dyestuff regarding jute fiber and discusses their benefits and shortcomings. Plain woven jute fabric samples of 261 GSM were dyed with 0.5%, 1.0%, and 4.0% shade of basic and reactive dyes. Then the dyeing performance of both dyestuffs was analyzed. It has been found that exhaustion of basic dye is considerably greater than reactive dye, while this exhaustion decreases for basic dye and increases for reactive dye with the increment of respective shade percentages. This phenomenon has also been verified through the absorption curve, i.e. K/S value of fabric dyed with both dyestuffs in three different shade percentages. Again strong covalent bond is formed during the fixation of reactive dye with the cellulose of jute fiber, and at the same time no strong bond was created in case of basic dye. Finally the color fastness properties have been assessed through rubbing and washing. Both the dye classes have shown nearly similar ratings in case of dry rubbing. However, in case of wet rubbing and wash fastness to color change and color staining; the samples dyed with reactive dyes showed superior fastness ratings over the basic dyed samples.

摘要

本文考察黄麻纤维的活性染料和碱性染料的染色性能，并讨论了各自的优缺点。在本研究中，使用 0.5％、1.0％ 和 4.0％ 色调的碱性燃料和活性染料对 261 个 GSM 平纹黄麻织物样品进行染色。然后，分析两种染料的染色性能。研究发现，碱性染料的吸尽比活性染料大得多；而随着各自色调百分比的增加，碱性染料的吸尽下降，活性染料的吸尽上升。这种现象也被吸收曲线（即在三个不同色调百分比条件下用这两种染料染色的织物的K/S值）所证实。研究再次证明，在定影期间活性染料与黄麻纤维的纤维素能形成强共价键，而在同一时间内使用碱性染料则不会形成强共价键。最后，本研究通过摩擦和洗涤对色牢度性能进行了评估。这两种染料在干摩擦条件下表现出大致相同的色牢度。然而，如果考虑涉及到色变和染色的湿摩擦和洗涤牢度，使用活性染料染色的样品比碱性燃料染色的样品具有更出色的色牢度。
