Preventing mohair from matting together

i did a test piece for dying with dark brown rit dye and I noticed my mohair came out matted together.

I microwaved 35 oz of water and used approx half a bottle of rit dark brown liquid dye and immersed the hair in the water. I took out the hair after 5 minutes and squeezed out the remaining dye.

I then ran the hair under running water, and I’m thinking this may have caused it to Matt together possibly?

Thoughts?
