Consumer preferences for textile products are largely determined by sensory characteristics. In this context, the tactile senses are among the most important. Various sensory evaluation methods have been developed to characterize the tactile feeling from the consumer's point of view. However, sensory assessments are time-consuming and expensive. Therefore, reliable and practical methods are needed in order to predict sensory tactile attributes in an accurate manner so as to improve both student education and industrial product development and quality control stages.
From a subjective angle, the evaluation of sensory comfort can be done by conducting tests of feeling and touching the assessed material or, in a more complex manner, by actually wearing the fabric.
The degree to which the test subjects perceive comfort requires further rating of those descriptors that are considered to capture the essence of several fabric properties. These properties are being selected so that they would be the most relevant for the garment testing and evaluation process. The assessment of the perceived sensation can be done by granting marks that rate its intensity, by comparing it to a designated standard sample or by comparing the samples subjected to evaluation among them.
One of the proposed and used methods is based on differentiating sensations by granting marks on a scale from 1 to 5, using the corresponding symbol that was previously established. However, this particular method requires a lot of work and a large volume of processed information because of the amount of samples and the range of subjects involved. In order to simplify and render the subjective evaluation procedure more effective, we are suggesting the use of a certain software application. The users involved will upload input data, such as the qualifiers granted to each sample depending on the evaluation of the perceived sensation. Thus, individual matrices are being created, which represent a starting point for calculating the average values according to the marks granted to each and every sample by the group of subjects. The final matrix that results will be displayed for all users to see. By using the final matrices, it will be determined the minimum and maximum values corresponding to the batch of assessed samples. The software allows determining the position of every assessed sample on a minimized scale from 0 to 1, called the sensory scale, depending on the subjective evaluations. The final results will be featured in a table and in a chart too in order to facilitate their observation and interpretation by users. | Keywords
