Pilling is a normal effect of natural wool and cannot be avoided completely. Pilling is also a sign that it is a natural textile and that the wool has not been treated.

1. Prevention

a) In the production

  • Harder wools with a bigger wool hair diameter tend less to pilling than softer wools. The softer the wool, the smaller is the wool hair diameter and the higher the tendency to pill.
  • A higher turn of the wool thread includes the fibers stronger into the wool yarn. Less fibers are out and can get stuck.
  • By their structured mesh structure, rougher knit materials tend rather to pilling than smooth, fine-knit parts.

b) In Sales

  • Wool threads, which are dried strongly tend significantly more to pilling. Dry wool loses
  • elasticity. More wool fibers are out of the pattern, the wool feels shaggy.
  • Therefore slightly moisten wool articles once-twice a week with a flower syringe, to keep the concentration of humidity of the wool high.
  • Don’t store wool products in direct sunlight or near a heater. There they dry out very quickly.
  • Longer storage of wool items in well closed plastic bags.
  • Wool wax (lanolin) wraps the wool fiber as a protective cover and reduces the peeling tendency. While moistening the wool, give a squeeze of disana lanolin cure into the spray water.

2. Treatment

  • Pilling is an irreversible process. Pilling can neither be reversed by washing, nor by any other wet treatment. You can only remove the pilling nodules mechanically.
  • With slight pilling, the nodules can be plucked out by hand.
  • At medium high and strong pilling the nodules can be shaved carefully with a special pilling razor or a one-way wet razor. Do this very cautiously, not to injure the fabric.
  • Pilling nodules can be „polished“ with special pumices. (anti-pilling sponges)
