The Impact Of Natural Dyeing On Enhancing Physical Properties Of Cellulosic Fabrics Across Textile Structures

The study aimed to investigate the impact of fabric structure on fabric dye uptake rate and natural dyeing effect on physical properties of fabrics. Different blended linen/cotton structures (Plain 1/1, Twill 1/3, Twill 2/2, and Atlas 4) were used to examine the dyeing process variables, absorbance average, air permeability, elongation, and tensile strength. Noting the general weakness of the resulting color on most cellulosic compositions dyed with natural dyes, the effect of using (Solidogen) as a cationic agent was used to initially treat cellulosic textile fabrics to increase their dyeability. The difference in color strength between the untreated and treated fabrics was investigated through a variables study of cationization process. After reaching the best treatment conditions, color strength was measured and recorded. A noticeable increment was observed from K/S (1.00) up to (11.52) by an increasing ratio of (91.32) %. According to the fabric structure, the Plain achieved the highest color strength (11.52) whereas Atlas recorded the lowest (9.60). A slight decrease in the colorfastness properties and air permeability of dyed fabrics was observed. While an increase in tensile strength of Plain, Twill 1/3, Atlas 4, and Twill 2/2 was noticed respectively, there was an increase in elongation values for all the used textile structures.
