Here is a pic of one of towels I have 420 gsm. 70/30. Chinese made. The long knap is twice as long as the short.

The RC doesn't give length of knap on their website. Length of knap has nothing to do with quality of fibers used for manufacturing. Korean towels are always softer, and release dirt particles when washed much better then Chinese.

It's been my experience using Chinese towels, that over time they become rough to the touch, and also hold in dirt/sand, making them bad for polished paint.

I'm not saying these are a bad deal a $2.50 each. That's actually a good price. What I am saying is I wouldn't use these on paint.

And since I have 20 of these, 10 in yellow, 10 in grey, for interior use on non-delicate surfaces, I can't see any benefits from a knap that may be 1 or 2 tenths of a centimeter longer with the same fiber and blend.

Take one of these towels and drag it across your open palm, you will feel how it grabs your skin. If you have a really good Korean made towel it wont do this. It slides smoothly. A towel that grabs requires more pressure to use on paint then one that doesn't. Try a Microfiber Madness Crazy Pile against any towel. None are softer. But again your comparing a Rolls Royce to a Toyota Prius comparing a MMCP against a Chinese towel.
