Ir Spectroscopy Studies of the Textile Materials Structures With Natural Dyes

The scientific study examines the functional groups of the oregano shell dye for dyeing textile materials, the expansion of color capabilities and capabilities capable of resisting microorganisms. The aim of the study is to create a natural additive to save resources, environmentally friendly, natural coloring products, easy to manufacture and use manufacturing technology. Extraction of the walnut shell is necessary when dyeing and finishing fabrics and textiles. At the present stage, it is relevant to obtain and study natural dyes for textile materials. The use of natural dyes will improve the hygienic properties of products and increase the environmental friendliness of the finishing process. Thanks to the active extraction of natural dyes and expanded color shades, the possibilities of introducing natural dyes into the textile industry in the future are high. This is due to the fact that the raw material base is extensive, and the compliance of natural dyes with international environmental standards, as well as one of the priorities provided for by the strategy, is the rational use of natural raw materials. IR spectroscopic studies of textile materials using the developed dyes were carried out in the work. To improve the quality of dyeing and chemical properties, various modifying components were added to the dyes. The use of the resulting coloring agent in the dyeing of textile fibers will replace the import of synthetic textile dyes

Investigation of dyeing, antibacterial and antifungal properties of blended fabrics treated with plant-based dyestuffs and mordants as shoe materials

In this research article, it is reported the preparation and characterisation of four types of blended cotton-polyester based textile materials in different dye ratios with four kinds of natural dyes of agro waste (walnut shell, onion peel) and wildflowers (tansy, Hypericum) with/without mordants as antibacterial and antifungal species for shoe materials. The dyed samples were spectrophotometrically measured and the results were obtained as colour strength (K/S) as well as CIELab values. As a result, dyed fabrics with natural dyes showed yellow, grey, orange and brown colours. With the help of a mordant, aluminium-potassium, the dyed fabrics obtained natural, not distorted shades of these colours, and with the addition of copper sulphate, they showed changing yellow to light green, orange to dark red, grey to a darker shade of grey and brown to a darker colour. The dyed samples were tested for colour fastness to circle rubbing and satisfactory results were found. The fabrics dyed only with natural dyes and treated with natural dye and mordants were evaluated for antibacterial and antifungal properties against Escherichia coli, Staphylococcus aureus, and Candida albicans. The results indicated that fabrics treated with these natural dyes and mordants had excellent antibacterial and antifungal activity. All natural dyes and mordants used in this study were the most effective and showed the maximum inhibition zone, indicating the best antimicrobial and antifungal activity against tested microbes. The results showed that all these natural dyes can provide some antibacterial and antifungal activity on mixed fabrics. © 2023 The Authors.

Physical and Mechanical Properties of Cotton/Polyester Based Fibers for Shoe Uppers and Lining Products [1]

The purpose of the study was to evaluate the physical and mechanical properties of various textile materials based on polyester and cotton for shoe uppers and lining. For that purpose, the influence of the ratio of a mixture of cotton and polyester fibers on the quality of the fabric was investigated. As a result, fabrics with the same composition but different yarn numbers differed from each other in specified properties. With an increase in the content of polyester, all specified properties increase except for vapor permeability, which makes it possible to correctly select the composition of fabrics for shoes
