properties of dimensional stability and elasticity which are provided from woven
and knitted fabrics separately. These fabrics consist of several threads (warp)
which are formed as loops via needles and run through the fabric mainly in a
vertical direction. These fabrics may be produced on a flat or a circular warp
knitting machines. </span> <span style="font-size:10pt;font-family:’Times New Roman’, serif;border:1pt none;padding:0cm;"> This study aims to investigate the influence of washing
cycles (1, 5 and 20) on stretching (%) and air permeability properties of the
polyester warp knitted fabrics of different weight. </span> <span style="font-size:10pt;font-family:’Times New Roman’, serif;">In order to analyze the effect of washing process on stretching

Air Permeability Tester devices were used respectively. Additionally, the
changes in fabric weight according to washing cycles of 1, 5 and 20 were also
evaluated. According to test results </span> <span style="font-size:10pt;font-family:’Times New Roman’, serif;">; the stretching properties and air permeability
values of the polyester warp knitted fabrics produced in different weights
varied according to the laundering cycle which emphasized that caring processes
should also be considered during the evaluation of mechanical properties (such
as stretching, air permeability properties) of polyester warp knitted fabrics.  <span style="border:1pt none;padding:0cm;"> </span> </span> </p> <p> </p>}, number={3}, publisher={Bursa Uludağ University}
