A METHOD FOR ACHIEVE COLOR AND PERMANENT ANTIBACTERIAL FUNCTIONALITY IN TEXTILE MATERIALS USING REACTIVE DYE AND SILVER IONS IN A SINGLE BATH.

Abstract

This invention relates to a dyeing process that imparts both color and permanent antibacterial properties to textile materials in a single step, by adding a silver compound containing water-soluble silver ions to the dye bath during the reactive dyeing process. Within the scope of this invention, silver ions bind to the fiber structure by forming coordinative bonds with dye molecules in a reactive dye bath, thus providing a lasting antibacterial effect without the need for additional antibacterial finishing treatments.

DESCRIPTION OF THE INVENTION 30 The purpose of the invention is to achieve a single-step reactive dyeing process for textile materials. The goal is to develop a process that provides both color and lasting antibacterial properties. 4 For this purpose, a silver solution containing water-soluble silver ions is added to the reactive dye bath. The compound is added and silver ions form a coordinative bond with the dye molecule. This allows it to bond to the fiber surface. In this way; The need for a separate antibacterial finishing process is eliminated, 5 Water, energy and time are saved. The antibacterial effect is ensured to be resistant to washing, The color tone and fastness properties of the dye are preserved. The invention can be implemented in existing reactive dyeing lines without requiring additional equipment. It offers an industrial solution. 10 Other advantages of the invention include: • Industrial applicability: Without altering existing reactive dyeing conditions. It is feasible. It does not require additional special processes or equipment. • Cost and time savings: No need for separate finishing or nanoparticle synthesis steps. Because there is no remaining labor, production costs and labor requirements decrease. 15 • Color and quality preservation: Antibacterial functionality is achieved in a single step. The color tone, color yield, and fastness properties of the dye are not negatively affected. • Environmental benefit: The environmental burden decreases as water and energy consumption is reduced, and Sustainable production is supported.

The preferred alternatives for the method of gaining advantage are simply better understood in the subject. 10 for the purpose of understanding and without creating any limiting effect It is explained. Reactive dyeing: Used for coloring cotton and other cellulosic fibers. It is a dyeing method that forms a chemical bond. A strong chemical bond is created between the dye and the fiber. (Covalent bonding) occurs, which increases color fastness. • Textile antibacterial finishing 15 Processing and functionalization: Inhibiting microbial growth on the textile surface. It includes chemical applications aimed at imparting properties. Both in terms of health and... It is widely used in comfort-oriented applications.

Additionally... There is growing interest in sustainable processes in textile production, particularly in saving water, energy, and time. It encourages the growth of the area. The main components used in the invention are: 25 Reactive dye, Water-soluble silver salts, pH regulators, They are complexing and dispersion aids. Reactive dyes create a strong covalent bond with the fiber, providing permanent coloring. Silver ions, on the other hand, form a coordinative bond with the dye molecule and When the dye binds to the fiber structure, silver ions also become permanently attached to the fiber surface. 6 This ensures that the antibacterial effect remains resistant to washing. It is possible for it to arrive. The excipients ensure the homogeneous distribution of silver ions within the dye bath. By providing this, it prevents settling, color loss, and bonding problems. The process proceeds as shown in the following example application; - Pre-treatment of textile materials, - Preparation of the reactive dye bath, including necessary salt, pH regulator, and Excipients are added, - Adding water-soluble silver salts to the dye bath, 10 - The fabric is dyed in a dye-silver bath under standard reactive dyeing conditions. processing, - At the end of the process, the fabric undergoes standard washing procedures and is dried. The resulting product has both the desired color tone and is long-lasting. It exhibits antibacterial properties. 15 This process eliminates the need for a separate antibacterial finish, reduces production time, and saves energy. and it saves water, it is applicable in existing painting lines. It provides a technical advantage in this respect. Table 1. Antibacterial activity results.
