Abstract

Introduction. The assessment of the macro- and microporous structure of textile fabrics is increasingly relevant for predicting their permeability, dyeability, and decorative potential. This evaluation plays a crucial role in determining the hygienic properties of clothing materials, optimizing dyeing and finishing processes, and assessing the filtration capabilities of technical fabrics in various dispersed media.
Problem Statement. Challenges persist in accurately predicting the permeability of textile fabrics, as well as in determining the optimal parameters for dyeing and finishing processes.
Purpose. The purpose of this research is developing a rapid, cost-effective, and accurate method to evaluate the macro- and microporous structure of textile materials is essential for assessing their permeability and suitability for dyeing and fi nishing processes.
Materials and Methods. To study the porous structure of textile fabrics, we select the fabrics that varied in the thread structure — yarn produced by traditional and shortened methods — and in the fibrous composition. The first fabric is made from complex polyamide threads in a plain weave, the second from twill-woven polyester fiber yarn, and the third differs from the second in the structure of the weft thread. The macro- and microporous structures of these textile fabrics have been assessed by means of drying methods and sorption thermograms.
Results. The micro- and macroporous structures of textile fabrics made from polyamide threads and polyester fibers have been compared. It has been found that the fabric made from polyamide threads exhibits a significantly higher sorption capacity than the fabric made from polyester fibers. This finding suggests that the fabrics made from polyamide threads possess a more developed microporous structure. This fact enhances their dyeing and decorating capabilities as compared with the fabrics made from polyester fibers. A comprehensive approach, utilizing both drying methods and sorption thermograms, has been employed to evaluate the macro- and microporous structures of the textile fabrics.

Conclusions. The proposed comprehensive approach enables comparative studies of various textile materials, allowing for the refinement of technological processes for dyeing and decorating, as well as the identification of potential applications for these materials.
