Relationship between reactive group chemistry and printing properties of heterofunctional reactive dyes via screen printing.

Screen printing of cotton fabric using newly synthesized azo reactive dyes was carried out in the present study. Functional group chemistry and its effect on the printing properties of cotton fabric by varying the nature, number and position of reactive groups of synthesized azo reactive dyes (D1-D6) was studied. Different printing parameters (Temperature, alkali and urea) and their effect was explored on the physicochemical printing properties e.

Structural modifications in Bermuda grass [ (L.) Pers.] ecotypes for adaptation to environmental heterogeneity.

Introduction: It is well known that different ecotypes adopt different mechanisms to survive under environmental stress conditions. In this regard, each ecotype showed different type of modifications for their existence in a specific habitat that reflects to their ecological success.

Methods: Here, differently adapted ecotypes of Bermuda grass [Cynodon dactylon (L.
