This paper proposes a comparative study of the tensile behaviour of the knitwear under linen made of 100% cotton yarn in 1:1 rib with Nm 50/1 and 2:2 rib with Nm 40/1. The rib structures 1:1 are more dimensionally stable than the rib structures 2:2, on both directions, due to the higher number of yarn-yarn contact points and due to the distribution of the rib platinum loop. The studies made on the proposed structures have demonstrated that it can be obtained an almost identical dimensional stability, which fits in the limits ±2, if for the rib structures 2:2 thicker yarns are being used. After knitting and finishing, the structure parameters of the knits are determined and then they are subjected to the tensile strength, and the result after processing the obtained data, it is concluded that the behaviour of the knits at the tensile stresses is comparable to the real situation. The study is carried out on both directions of the knits, in the horizontal direction, of the rows of meshes and in the vertical direction of the strings. The performance-elongation diagrams are represented through graphics and the results obtained are interpreted, the data being used to determine the structure parameters of the knits in order to obtain maximum dimensional stability at wearing.

Nowadays, all the more we witness to a rapid technological development and the entanglement of information technology in the formation and maintenance of human connections. As a consequence, the educational system must comply with the current flows. The use of information and communications technology in education exerts a crucial function in increasing the learning process and augmenting its efficiency. Taking into account these premises, we develop a novel approach for the study of a subject of textile metrology. Laboratory practices are fundamental in teaching and learning Metrology by enabling students to acquire practical skills through measurements which allows a more thorough comprehension of the delivered content. Design of this laboratory represents a challenge from the perspective of learners and teachers as well, since it aims to address all learning styles and enhance student's motivation. The laboratory combines a face-to-face teaching and online learning in a blended learning framework, by combination of text based learning with audio-visual support. The virtual laboratory will provide an exhaustive content comprising a description of the dynamometer, measurements that can be accomplished, determined parameters for fabric tensile strength testing, sample preparation and procedures. In order to attract student's attention, the presentation is performed in Power Point. Furthermore, hyperlinks ensure the transition from unit to unit or to other significant issues within an unit. After measurements, follows the calculation and statistical - mathematical processing of the values, according to the applied standards. For the calculation of typical survey values like arithmetic average, dispersion, standard deviation, coefficients of variation, kurtosis and skewness, we use the Excel program. These obtained values will be imported into Power Point and will be compared with those provided by the device, knowing that the device has a touch screen console for control, adjustments and for displaying of measurement values.Thus, this approach can be used either to train students prior they conduct hands-on measurements or after to deep their knowledge. By using this approach, the learning process can be supported independent of the student's location and available infrastructure.
