In this study, the authors used 03 fabric samples with Three fabric samples with the same yarn count, the same yarn composition ratio of 85% PA/15% Spandex, but with different weave knitting patterns (basic single, single variable). type, jacquard (basic single, derivation single and jacquard type) were used for experimentation. The experiments included: Fiber density Determining fabric density according to the standard TCVN 5794 - 1994
Fabric weight (g/m2) according to standard TCVN 8042:2009
Fabric thickness according to standard TCVN 5071: 2007
Breathability according to TCVN 5092:2009 standard. Research results showed that: The breathability of the fabric depends on the weave type of knitting pattern, thickness and weight g/m2
The thinner looser the weave knitting between the loops of the fabric, the greater the breathability of the fabric and vice versa
The larger the volume and thickness of the fabric, the more breathable the fabric tends to decrease the less breathable the fabric became.
