Abstract: | In this study, the dimensional and some physical properties of plain knitted fabrics made from 50/50 bamboo/cotton blended
yarns are investigated. In order to see the differences and similarities, the results are then compared with those for similar
fabrics knitted from 50/50 conventional viscose/cotton and 50/50 modal/cotton blended yarns. Each fabric type was produced
with three different stitch lengths. After all fabrics were dyed under identical dyeing conditions, they were subjected to
dry and full relaxation treatments. For dimensional properties of fabrics, course, wale and stitch densities were measured.
Then, by calculating statistically best-fit lines passing both through the experimental points and the origin, dimensional
constants i.e. k values were predicted in terms of the fiber types. The result show that each fabric type knitted from bamboo/cotton, viscose/cotton
and modal/cotton blended yarns behaves in a similar manner. However, in both dry and fully relaxed states, the modal/cotton
knitted fabrics tend to have slightly higher k values than the bamboo/cotton and viscose/cotton knitted fabrics. For physical properties, fabric weight per unit area, thickness,
bursting strength, air permeability and pilling were evaluated. The results show that the weight, thickness and air permeability
values are independent of the fiber type. Plain knitted fabrics from modal/cotton blended yarns have the highest bursting
strength values. Plain knitted fabrics from bamboo/cotton blended yarns tend to pill less. |
