go throuugh, find and remove line

I have a file which I want to go through with a list of strings. When a string in the file is found, the whole row, where the string was found, sholud be removed. Then, the file should be serched for the next string in the list...

I did like this:

while read ORDERBOOKS; do

grep -iv $ORDERBOOKS file.txt > ProteusNew.xml

done < orderBooks.txt

but then, it only solves the problem fore the last string in ORDERBOOKS, which is a list of with collum.

The file that has small strings to be matched we can call a patternfile, the big file, datafile.
Start with this:

grep -v -f patternfile datafile > new_datafile
