Grey jute fabrics were given pretreatment such as scouring which was followed by enzyme treatment. These pretreated jute fabrics were subsequently bleached with hydrogen peroxide. Dyeing of these bleached jute fabrics was carried out with four different classes of reactive dyes, namely cold- brand, hot-brand, vinyl sulphone and HE-brand reactive dyes, following the conventional exhaust method and pad-batch method, i.e. minimum application technology method. With respect to dyeing behaviour, it was found that dye uptake and wash fastness property of a dyed fabric produced by the pad-batch method is well comparable with that produced by the conventional exhaust method. Irrespective of the methods of dyeing, scoured-bleached and scoured-enzyme treated-bleached jute fabrics show better dye uptake and fastness property compared to grey-bleached fabrics. Weight loss and strength loss increase while bending length decreases with the increase in pretreatment stages. Enzyme treatment of a scoured jute fabric before bleaching produces the minimum bending length among all the samples. The pretreatment process is found to have some detrimental effect on the tensile properties of a jute fabric and as the number of pretreatment steps increases, the tenacity of the fabric decreases. Reactive dyeing of pretreated jute fabrics further reduces their tensile strength by around 10% irrespective of the method of dyeing and the pretreatment process. So, minimum application technology can be well adopted for dyeing of a jute fabric with reactive dyes. The process is simple, cost effective as it utilises dye to its maximum extent, requires minimum energy and is suitable for use in cottage and small-scale industries. |
