Methods and Applications (Oxford: Oxford Science This research explored the possibility of using linseed oil as a carrier for the pigment from Scytalidium cuboideum as a textile dye. used, potassium acetate appeared to have the greatest effect on the dyeing properties. While mechanical testing showed no strength loss in treated fabric, colorfastness tests showed significant changes in color in response to laundering and bleach exposure with variable effects across fabric varieties. 0000009916 00000 n Two reactive dyes are Reactive Red & Reactive Yellow and Two materials: Nylon, Silk as well as Silk fiber & Nylon Yarn, were examined.

Reed, Auburn University, Auburn, Ala. T extile manufacturing plants are re- quired to remove color from efflu- ents. Cotton, rayon, and some nylons are dyed by this relatively simple dye. %���� In this paper, the natural dyes are extracted and fabric dyeing is analyzed by applying dye on 100% pure cotton. 0000011026 00000 n Working off-campus? %PDF-1.3 %���� type of reactive group(s) present in the dyes. %PDF-1.5 Red F-B, Cibacron LS and Remazol Black B applications being shown in Figures 1, 2, and 3. again until no further dye desorbed. Materials The combination of sodium and potassium tartrate dye resulted in the best final hue, between the yellow and red regions of the CIELa*b* space (L = 49.84, a* = 5.41, b* = 45.52). The results showed that the sequence of the fastness tests used changed the color properties of the fabrics in different ways. The reduction of about 8% dye, 12.5% Na2CO3 and 20% steam can be achieved using the developed dyeing technology. -�Ew���U���\��i�h�Y�����B�K�6J�4^�yvT���:Tx@�'�����b�\�TH�|�L�*�b�faB�w�D���z����y٣"�u��s���Β�� q���ǟ�I�� �B�9�ë!��[T���F9���������Q�`��t��R��(TXN�����}bq��{��?_�����$��b��-nX9����o ҷ �� ~�:���Tho�n, #t$�y;Y�eYQ[��͟&,-�"�4-i�V ���j�ͫ.�D^�o�Pq����������qx(ڊ$y�2�Z���ϟ�-�O8oB�S�4�9Ld�%�2t����~K����&�X�}*a�ag�(��]��{�Û�o������6����W���ljΦ���u��M����A`��C��U� I.

For the hetero-bifunctional reactive dye (scheme (A) in Fig. The appropriate dyeing conditions were recommended as follows: the padded fabrics were placed at 30 °C for 120 min to complete the pre-diffusion, and then fixed in atmospheric saturated steam for 4 min. © 2008-2020 ResearchGate GmbH. Chi‐wai Kan, Institute of Textiles and Clothing, The Hong Kong Polytechnic University, Kowloon, Hong Kong. 0000001976 00000 n 0000012516 00000 n This paper describes a new method to dye cotton with selected reactive dyes by long-liquor – or so-called ‘exhaustion’– processes under neutral conditions. The changes in hardness and the pH value in a water pool did not result in a significant change in CIE L*a*b* values of dyed specimens, and no chromatic change was found in dyed fabrics. Introduction Reactive dyes are probably the most popular class of dyes to produce 'fast dyeing' on piece goods. Cotton & cotton with reactive dyes pdf 1.
