1 The pilling issue

Pilling is the name of the fabric defect represented by the mounds of fibers that clump together on the fabric’s surface.

There are 4 pilling stages: fluffing, entanglement, formation of mounds, and shredding.

Various factors influence the pilling formation:

  • Fiber strength: if the strength of the fiber is high, the formation of hairballs by friction is more frequent
  • Fiber thickness: the finer is the material, the higher the risk of pilling.
  • Friction coefficient: higher is friction coefficient, less pilling formation.
  • Different fiber blends: the thinner material positions on the inner part of the yarn, and the thicker and shorter migrates to the outside of the thread.
  • Fiber length: shorter fibers increase the pilling formation as they migrate to the outside of the thread.
2 Tackling the issue with anti-pilling finishing

To prevent the pilling formation, the best solution is to use finishing auxiliaries in resins form, that act as binders and fix the fibers, preventing migration to the surface of yarns and fabrics, and therefore minimizing the pilling formation.

CRILOTAN WRG FF is our handfeel modifier and antipilling finishing agent for woven fabric and knitwear.

It’s an acrylic copolymer in an aqueous emulsion compatible with anionic and non-ionic products, with zero add-on formaldehyde.

CRILOTAN WRG FF increases the abrasion resistance and antipilling effect, also with raised or emery cloths, imparts a full and soft hand through a colorless, elastic film on the fabric surface, and increases cohesion thread/weft and dynamometric resistance.

It’s also resistant to dry-cleaning and suitable for permanent finishes like wash & wear and easy care.
