In the total world production, the share of cotton fibres is gradually decreasing, so that new fibres are needed to replace or supplement them. A double bed circular knitting machine with a machine gauge of E17 was used to knit five samples of knitted fabrics in plain double jersey weft knitted structure made of 20 tex yarns. The samples were knitted using cotton, Lyocell, modal, micromodal and viscose yarns. The ring spinning method was used to spin cotton and micromodal yarns, Lyocell yarns were spun using the air-jet spinning method, modal yarns were spun using the rotor spinning method, and viscose yarns were spun using the SIRO spinning method. The structure parameters and the tensile properties were determined for the unfinished and finished knitted fabrics, with emphasis on the percentage of elasticity when the knitted fabric was stretched in the course and wale direction. The mass per unit area of the analysed knitted fabrics ranged from 128 to 180 g/m2, while the volume mass ranged from 0.21 to 0.40 g/cm3. All the manufactured and analysed knitted fabrics were compared with cotton knitted fabrics. |
