This article presents the results of research carried out based on consumer assessment of the quality of clothing using sensory analysis. The study aimed to determine the role of the brand and information about it in assessing product quality and identify the quality parameters that distinguish brands of a similar quality level. An attempt was also made to classify popular brands of clothing available on the Polish market based on the parameters that determine their quality. A significant impact of the brand name on the sensory assessment of clothes’ quality has been reported. The study has shown that assessors attribute higher rating values to quality features when they know the product brand; moreover, the brand and its information shortens the assessment time, which may suggest that it simplifies and facilitates consumers’ decision-making process. The result analysis has led to the identification of three groups of the factors determining the quality of clothing products: fabric composition, workmanship, and all other variables. It has also led to the separation of three clusters, characterized by different levels of product quality, for which sets of features distinguishing a given category were determined.
The aim of the study is to show how the washing process, while considering the type of washing agent and number of wash cycles, determines the durability of hydrophobic finishes of laminated fabrics. The samples of material were subject to multiple wash cycles in clear water and with the use of two types of washing agents, namely, an ordinary washing powder and a detergent recommended by manufacturers of functional clothing. The washed materials were subject to spray test and its waterproofing and degree of surface wetting were evaluated. The tests have shown that waterproofing of membrane laminates with DWR (durable water repellent) coating become deteriorated during washing treatment and the use of special detergent does not guaranty the maintenance of better coating properties than an ordinary washing agent.
