What does Judges 16:14 mean?

So while he slept, Delilah wove the seven braids of his hair into the fabric and tightened it with the pin. Again she called out, 'Samson, the Philistines are here!' He woke up and pulled out the pin, the loom, and the fabric. Judges 16:14 - Modern Text Bible

(Delilah tries this new method, but Samson wakes up and easily frees himself, showing his strength is still intact.)
