Cotton Dyeing

Use of sodium hydrosulfite in the dyeing of cotton with vat dyes is criticized for generation of sulfur compounds leading to air and water pollution. In this study, attempts were made to dye cotton with alkaline pectinase along with iron (II) salt as an alternative formulation. A 43 Box-Behnken design was used for statistical analysis of performance for this new reducing system and to obtain optimum parameters for cotton dyeing. The results showed that alkaline pectinase along with iron (II) salt was quite effective in developing comparable dyebath potential, dye receptivity on cotton with comparable dye strength, and colorfastness, as compared to the hydrosulfite-based reducing system. Dyebath stability in presence and absence of dye also showed superior results compared to that of the hydrosulfite system.

Analysis Of Performance

Subject. This article discusses the problems of socio-economic development of monocities. Objectives. The article aims to consider the industry specialization of special economic zones (SEZ) and determine the extent of their mutual influence. Methods. For the study, we used a statistical analysis. Results. Based on the analysis of performance indicators of industrial special economic zones, the article breaks down economic zones and monocities by federal districts and describes their sectoral trends. The article emphasizes that when creating economic zones, the category the nearby monocities belong to was not taken into account, and there is no interaction between the zone and the monocity. Conclusions. On the basis of the studied, it can be assumed that when creating industrial special economic zones, the objective to improve the socio-economic situation of nearby monocities was not set at all.
