Well, if you stick strictly to the KJV. then it only mentions linen and wool. But the KJV is not that good a translation. Most newer translations, attempting to be a more accurate translation, say something like...<quoted text>
You clearly don't understand Scripture.
It'd be a good idea if you stop trying.
"'Do not wear clothing woven of two kinds of material."
--New International Version
"Do not wear clothing woven from two different kinds of thread."
--New Living Translation
"...nor wear a garment upon you of two kinds of material mixed together."
--New American Standard Bible
The original text (you know...the one in Hebrew, not English) talks of two different fabrics.
For a fairly comprehensive list of what different English version of the Bible say, see...
So tell me again, who clearly doesn't understand scripture?
