Is the shirt pure cotton or cotton mixed with polyester?
Cotton and polyester blended shirt, indeed more crisp, easier to manage, but not easy to wrinkle, but personal comfort will be greatly inferior to cotton clothes. Especially for you, polyester fiber (polyester) is higher in content than cotton. If your skin is more sensitive, but it is next to wear a shirt (do not wear bottoming), it is recommended to buy cotton well.
Personally, relative to polyester, a good shirt is still made of cotton. Plus polyester, the feel and comfort of the dress has always been worse, but the price can be cheaper.
Of course, this is just plain cotton and polyester. Cotton shirts can also be done anti wrinkle treatment, better liquid ammonia anti wrinkle treatment, treated cotton shirt, wrinkle resistance is also very strong.Pet can also do moisture treatment, so that the sweat, sweat absorption function will be relatively strong, mostly personal sportswear will be used (Adidas, Nike have seen), you can also add anti UV treatment (Columbia and other outdoor sports brands like outdoor shirts). After finishing, the space of polyester fiber is larger than cotton.
Cotton is stronger in air permeability and water absorption than polyester fiber. Polyester strong is the strength (not easy to break), anti wrinkle, color ability (color can be dyed more bright, more solid) and so on.
