Annotation:
Terry fabrics are very popular materials which may be used for home textile, of baby clothes and as a result of the large scale of production of medicine and hygiene products. The structure of the terry fabric is characterized by its complex weave which is obtained through interlacing two systems of warp and one system of weft. The loop pile is one of the most important elements of the terry woven fabric structure because the appearance of the product and many other properties depend on the loops formed on the surface of terry fabrics. Water absorption is important for terry fabrics as well. Consequently, in this study, water vapour absorption and water evaporation from terry fabrics are investigated. Other extremely important physical properties of terry woven fabrics are their permeability properties. Absorption and desorption properties of woven fabrics depend on their air permeability. Mechanical properties of terry fabrics are among the most important characteristics determining the service capability of the product; the strength properties of the products are influenced by the fabric strength and durability. Terry fabric finishing methods are being developed seeking not only to improve the fabric’s appearance or to provide it with additional functional properties but also in order to increase the demand for terry woven fabrics. The assessment of terry fabric wear was determined investigating the changes in mechanical properties after abrasion impact. The analysis also includes the predicting of the quality of terry fabrics: the dependencies of indices are expressed by mathematical equations and evaluated as complex; the determination of the influence of water, heat, mechanical, and chemical impacts/finishing on the properties of the fabrics is performed.
