Functionalization of Some Natural Thread Properties for Needlecraft in Children's Apparel

This article discusses the use of some natural dyes (Turmeric, Natural Yellow 3, and Madder, Natural Red 8) to develop some properties of natural fibers (cotton and wool) as a treatment against bacteria and fungi, as an environmentally friendly method. The effects of this on these fibers were studied by conducting tests to measure the values (K\S) color data (L*, a*, and b*) at a specific λ max value. The results showed that the highest values were observed in the samples dyed with turmeric (for both types of fibers) followed by the mixture used to dye them (turmeric and madder), then the mixture used with the dye and finally madder gave high values. Fastness properties related to light, washing and perspiration were also determined. The antimicrobial effect (E. coli, Staphylococcus aureus, and Aspergillus flavus) is also detected by performing a microbial count (MIC) test to determine the minimum inhibitory concentration. It was found that antimicrobial activity appeared in varying proportions for the dyed threads compared to the control samples, depending on the type of fiber. The interaction between the microbes and the dyes was also studied. It has been found that using these dyes to dye cotton and wool threads produces threads with good properties that are distinguished from others by having antimicrobial properties, good stability properties, and different colors. It can be widely used to produce themed children's clothing because it is safe to use and has environmentally friendly properties.
