Polyester fabric import Bosnia and Herzegovina

I am opening a company in Bosnia, for manufacturing of sports equipment with a focus on jerseys/sport shirts.

I am interested in exporting those products from Bosnia to EU. And I am mainly intersted in polyester fabric, for jerseys. I am still not too familliar what gms should the polyester fabric be, so I would expect you assistance here. I am looking somewhere from 110 to 170gms poleyster fabric.
