My bath robe is made with high quality cotton thread and I love it. It's very soft, thick and absorbent. It also dries very quickly. In some countries, cotton thread is insignificant compared to threads like silk. But for me, fabrics made with cotton thread are not only useful and healthy, but also great quality and luxurious.
I realize all cotton threads are not equally nice. I had a cotton thread shirt once that literally ripped after a few uses. It was obviously made with old, poor quality cotton thread.
