Hi, Dear friends. I hope you are well and enjoying your time

For any kind of fabric whether it is woven fabric or knit fabric, air permeability is an important property to check. Air permeability is closely related with several aesthetic and application-based properties of any fabric. If any fabric is air permeable it can be comfortable in summer season but similarly it is very much problematic in the winter season. For or any tight or compact fabric air permeability must be determined.

So, here in this tutorial I have try to explain the basic issues of air permeability and its impact on textiles. I have discussed it in Bengali language and I hope you will understand better who are from Bengali native. By knowing the basic idea about air permeability anyone can decide about choosing any fabric for any specific season and with the same time they can select the level of air permeability for any specific application.
