Knitted fabrics are textile surfaces obtained by forming connections in loops of threads with needles
and auxiliary elements. Knitted fabrics are used in sportswear, women's and men's outerwear, underwear,
baby clothes, bath and beach wear, socks, etc. With digital printing, high quality prints with
clear contours and high color efficiency can be obtained on textile surfaces. Digital printing technology
is a significantly cleaner production method compared to other textile dyeing methods at every stage of
production. It reduces the production time by eliminating the technologies, it produces less greenhouse
gases and has a lower carbon footprint compared to conventional intermediate stages such as film preparation,
screen preparation in conventional printing methods. These features make digital printing an
effective coloring method within the scope of sustainability. After the normal pre-treatment processes,
a paste containing a suitable thickener should be padded in order to prevent ink spreading. In addition,
alkali, acid, urea, etc., which are necessary for the fixation of the dyestuff, can be added to this paste.
After the digital printing process, a fixation process is carried out to increase the penetration of the
dyestuffs into the fibers. Different types of fixation are implement according to raw materials and dyestuff
types. In this study, single jersey knitted fabrics obtained from raw materials of Cotton, Viscose,
Cotton-Hemp, Cotton-Modal, and Cotton-Viscose mixed raw materials were used. Before the digital
printing process, the amount of thickener in the pre-treatment paste was changed. After printing, fixation
time was changed and samples were obtained. In accordance with this purpose, the wale/course density,
thickness, and weight properties of the fabrics were tested. Bursting strength tests were applied to all
samples according to BS EN 13938-2 standard. The effect of change of raw material, thickener amount
and fixation time on burst strength was determined. Statistical analysis of the experimental results was
analyzed with the SPSS package program.
