70% alcohol means in hundred parts of it, 70 parts are pure alcohol, rest is water. 95% means 95 parts of pure alcohol in 100 parts, so 5 parts of water. It depends on the usage. As a solvent, 95% would be preferred. As antiseptic, both can be used, 75% being more common as medicinal spirit. For consumption, fairly dilute concentrations are preferred. Above 43% are rare so both the above concentrations are dangerous for consumption.
Pure alcohol is far more dangerous than adulterated alcohol because pure alcohol has one hundred percent alcohol in comparison to aldulterated alcohol which is less than 100 percent.

By distillation, though 100% pure is not attainable.
Yes.
Percale is a treatment for cotton. Your phrase 100 percent indicates the composition of cotton is 100 percent.
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
