IMPROVEMENT OF THE ERGONOMIC FUNCTION – AN ESSENTIAL CONDITION FOR ENSURING KNITTED PRODUCTS QUALITY
Journal Title: Annals of the University of Oradea. Fascicle of Textiles, Leatherwork - Year 2018, Vol 0, Issue 2
Abstract
The evaluation products quality in general and particularly in knitted fabrics starts with determining their most important quality characteristics as an initial step in the multicriterial analysis used to establish the optimum ratio between the requirements of the users and the product’s quality. The behaviour of the knitted products during use is essential for the beneficiaries, the ergonomic-constructive characteristics correlated with the comfort characteristics being used in the product quality evaluation. The quality evaluation implies establishing the representative characteristics as well as applying the standardized testing methods, in order to choose the optimum knitted variants for the required destination. Extensibility is an essential quality characteristic for form – fitting knitted products or areas of the product, that during dressing – undressing or wearing process, must modify in a significant and positive way their initial dimensions. For these reasons it can be affirmed that the ergonomic function of a knitted product is determined greatly by extensibility. Measuring extensibility on two stress directions is a compulsory test effectuated in order to properly design knitted products. For this purpose, in knitted products, the minimal and maximal extensibility areas are established, for a precise selection of knitted structure, structural parameters as well as the position of the product elements. The paper encompasses an experimental study on the comparative evaluation of the extensibility of eight knit variants used in the production of outer garments in order to assess their ergonomic function and implicitly the ability to guide the quality of the knitted products during their design.
