Sensory Study of Knitted Fabrics that Have Gone Through Washing Cycles with Domestic Softener. Part II: Influence of Ageing During the Washing Cycle and the Use of Fabric Softener on Sensory Properties

This study involved the sensory evaluation of knitted textiles which had gone through different domestic laundering treatments, with respect to whether the sensory attributes or a combination of the different sensory attributes measured can best predict the preference of consumers regarding comfort. We defined the parameter 'Degree of influence' for sensory attributes in order to check the level of the influence of ageing and the use of domestic fabric softener on each attribute. Principal component analysis (a statistical data analysis which includes appropriate criteria) was then performed in order to make a better interpretation of the sensory data by plotting a fabric map and sensory attribute map.
