You don't, because the question itself makes no sense.
If a user can WRITE to the directory, that means they can MODIFY what's there...including DELETE files. You can easily do read-only, but if you want what you're after, you need to use selinux for it. Since you asked about selinux TWO YEARS AGO
...you should already be familiar with it.
