This paper aims to study the possibility of electroplating copper coatings on chemically and chemical-galvanically nickel-plated acrylic fibers, to be further processed into yarn, fabrics, knitwear and nonwoven materials.

Electrically conductive fibers with different copper contents have been obtained, and the effect of electrolyte pH, its composition, current strength at the first and second cathodes, as well as the metallization time on the electrophysical, physical and mechanical properties of copper-containing fibers, has been studied.

The studies have shown that with an increase in the copper content, the electrical conductivity, the uniformity of the coating and the uniformity of the electrophysical properties (for chemical-galvanically nickel-plated fiber) increase. In the case of copper plating of chemically nickel-plated fiber, the coefficient of variation in electrical resistance increases with increasing plating time, even though the copper content increases, and the coefficient of variation in copper content and electrical resistance decreases. The physical and mechanical properties of copper-containing fibers differ slightly from the original (subjected to copper plating) and industrial Nitron fibers. With copper plating, the strength of the fiber practically does not decrease, and the elongation decreases somewhat, compared with the mass-produced Nitron fiber.

The physical and mechanical properties of copper-containing fibers are quite high, which makes it possible to be successfully further processed into yarn, fabrics, knitwear and nonwoven materials.

This study aims to investigate consumer ethnocentrism and determine its impact on actual purchasing behavior in relation to six product categories. It also examines the role of demographic variables as moderators in the relationship between ethnocentric tendencies and purchasing behavior.

A total of 467 completed questionnaires were obtained through convenience and snowball sampling. Data were analyzed using SPSS-24 and AMOS-23 software: SPSS to conduct the exploratory factor analysis and AMOS for the confirmatory factor analysis. Regression analysis was performed to determine the effect of ethnocentrism on purchasing behaviors; the SPSS process was used to test the moderating effects.

The consumer ethnocentric tendencies scale was collected in two dimensions: hard ethnocentrism, which influences actual purchasing behavior in five product categories; and soft ethnocentrism, which influences actual purchasing behavior in only two product categories. The results show that the effect of consumer ethnocentrism on purchasing behavior differs across product categories. Further, gender, marital status and personal income moderate this relationship.

Few studies investigate purchasing behavior across several product categories and the literature on consumer ethnocentrism does not address the impact of demographic variables as moderators in consumer behavior. This study contributes to the existing literature in four ways. First, it was conducted in Azerbaijan, a country with specific characteristics. Second, it examines the impact of ethnocentric tendencies on actual purchasing behavior. Third, it examines purchasing behavior in relation to six different product categories. Fourth, the moderating effect of demographic variables was tested.
