First ask if it is, then ask why; In conclusion, breathability is not directly related to polyester material.
Polyester is a component of fiber. The main component of sportswear is fabric, and the permeability of fabric determines the permeability of sportswear. There are many factors that determine the permeability of fabrics
Weaving methods: knitting, tatting, non-woven (knitting has elasticity, high air permeability, non-woven air permeability can be high or low, tatting is a relatively familiar field to me, let me talk more about tatting
Yarn thickness and density: the thicker the yarn, the denser the density, the worse the air permeability; on the contrary, the thinner the yarn, the thinner the density, and the higher the air permeability
Finishing: after the calendering, coating, film pasting and other processes, the air permeability will be poor, but other indicators will be improved (such as cashmere proof, wind proof and other properties)
Conclusion: As the main force of sustainability, polyester represents the advanced productivity and consumption concept from a drop of oil to a piece of clothing, which can be purchased with confidence and boldness. Polyester is making great strides on the road of sustainability and degradability, which does not mean it is cheap.
