Abstract
Kompresiono ponašanje tekstilnih materijala uslovljeno je njihovom strukturom, svojstvima vlakana, kao i kompresibilnošc'u i površinskim svojstvima pređe. Usled ograničenog broja istraživanja uticaja upredenosti pređe na kompresiona svojstva tekstilnih materijala, ovo istraživanje je posvec'eno upravo ispitivanju efekata upredenosti pređe na kompresiono ponašanje glatkih DL pletenina. U tu svrhu su od tri različito upredene pamučne pređe proizvedene tri glatke pletenine koje su podvrgnute uzastopnim kompresionim ciklusima. Analizirane su dobijene kompresione krive, i izračunati su specifični parametri koji opisuju kompresiju pletenina. Koristec'i ove parametre, izračunate su neelastične komponente deformacije pletenina. Rezultati su pokazali da variranje upredenostsi pređe, koje direktno utiče na gustinu pakovanja i pokretljivost vlakana u& pređi, kao i na strukturu pletenine, omoguc'ava adekvatno projektovanje kompresionih svojstava glatkih DL pletenina.
Sažetak
The compression behaviour of textile fabrics is influenced by their structure, fibre properties, and the compressibility and surface properties of yarn. Due to the limited research on how yarn twist affects the compression properties of textile fabrics, this study examined the influence of yarn twist on the compression behaviour of plain knitted fabrics. Three plain knitted fabrics were produced from cotton yarns differing in twist intensity. The knitted fabrics were subjected to successive compression-release cycles. The compression-release curves of plain knitted fabrics were analysed, allowing for the calculation of specific compression parameters, including recoverable and irrecoverable compression. Using these parameters, the non-elastic deformation components were calculated. The results indicated that varying the yarn twists, which directly influence the packing density and fibre mobility in yarns, as well as the fabric structure, allows for the adequate design of the compression behaviour of plain knitted fabrics.
