Impact of internal notation and hetero bifunctional reactive dyes on color performance, mechanical and dimensional stability of cellulose-based biomaterials

Abstract

Internal notation factors influence the quality of cellulose-based biomaterials dyed with hetero bifunctional reactive dyes. Different internal notations of materials, such as Single Jersey, Rib and Interlock affect different coloration parameters like dye uptake, color fastness and strength. This research work aims to analyze the influence of various internal notations on color performance with hetero bifunctional reactive dyes. It also intends to identify the varying shades and the manufacturing internal notation factors for achieving consistent color quality and durability across different types of cellulose-based biomaterials. Seven cellulose-based biomaterials with various internal notations (Single jersey, 1×1 Rib, 2×1 Rib, Interlock, French Terry, Single Lacoste, Pique) were analyzed, colored with various dye uptake levels, such as light, medium, and dark. The investigation measured color strength, color parameters (L*, a*, b*, c*, h), surface morphology, color fastness, mechanical strength, shrinkage, and spirality. Standardized testing methods and instruments were employed for quality assessment. It has been observed that internal notation of materials significantly impacts dye absorbency with Interlock appearing brightest (K/S value 11.5). SEM analysis reveals surface morphology differences, affecting dye absorption. Color resistance varies with fabric internal notation while bursting strength differs across fabric types.
