Ask HN: Do you prefer cotton or bamboo bed sheets?

I am in the process of launching my self-clean bedding fabric that doesn't require frequent washes. In the weaving process, we need to have a filler yarn made of cotton or bamboo. HN has helped me in shaping up the launch of my idea and I am here to ask you again for the final suggestion. Do you like the feel of bamboo better than cotton? I would love to get your feedback on the website below as well. http://bit.ly/MsGedD Signup: http://bit.ly/1j8e0Q2
