I think the fabric of the white coat. Pure cotton fabric: Good moisture absorption and breathability, comfortable to wear, very suitable for summer wear, but the white coat of pure cotton is not so easy to take care of. It is easy to wrinkle and yellow, stiff, wear-resistant and elastic, but there are still many people who like pure cotton white coats. It does have something that can't be discarded, which is safe, healthy and skin-friendly. Polyester, polyester card and polyester fabric are also popular white coat fabrics, which are the first choice of many manufacturers. The white coat made of them will look very textured and heroic, but compared with pure cotton, it feels too hard and airtight, suitable for winter wear.
