Twisted fiber is also a very popular method of fiber transportation. The fibers of the mattress and the mixed fibers can be rolled up. The 20 kg reels are the most used reel size. However, coils of 50 kg or even 100 kg could also be manufactured from our torsion machines. Twisted fiber is mainly used for the manufacture of mattresses. Twisting gives the fibers a bending effect necessary for the latex to penetrate well into the fibers during the manufacture of latex mattresses and cushions.
