Does lanolin affect dreads?

I'm a fiber artist, I clean, dye, spin, and weave my own
fibers including wool. I decided that I would try a wool pillow case to help my
dreads form. I was riffling through my work room and found a 75% wool, 12.5%
silk, 12.5% bamboo fiber bolt of fabric which I made some time ago that was
exactly the right size to make a pillow case out of. Originally I was going to
make a vest or shrug out of this fabric so I left some of the natural sheep
oil/grease (lanolin) in the wool to help water proof the cloth naturally. I'm
wondering if the lanolin will hurt or hinder the dreading possess and whether
or not I should super scour the pillow case with hot water and soap to remove
any remaining lanolin? Does anyone know how lanolin affects dreads?

I am not sure. I work with lanoline in making skin care products. For lanoline is significant that it can take in it lot of water, by that it woud be hard to wash it of hair. It goes in cathegor of waxes in pharmacy- Adeps Lanae..so as wax, I woud not put it in dreadlocks.

Thanks, I guess I'll give my pillow case a good washing :D
