Clusters, also referred to as fiber balls, are small agglomerates of polyester fibers, forming a sphere, obtained by particular mechanical equipment in the manufacture of this type of product.
Crimp are waves or folds per unit of length. Is introduced into the fiber to provide cohesiveness, volume and allow its carding. Crimp can take several forms: saw, wavy or helical, providing different properties to the final product.
- Decitex (Dtex)
Decitex or Dtex, is the unit which determines fibers proportion. It is the weight in grams of 1000 m of yarn or filament. 1Dtex = 0.1 tex
- Bicomponent or Low Melting Fibers
Allow the connection / cohesion of the fibers that compose the filling when its manufacturing process involves heat. They are manufactured from two polymers with different physical and chemical properties, sometimes with different melting points.
- Short Fibers
Short fibers length is equal to or less than 32mm.
- Long fibers
Long fibers have a length of more than 32mm.
- Hollow Fibers
Are fibers whose cross section has at least one hollow channel within the fiber filament.
- Siliconized Fibers
Concerning its surface finish, fibers can be siliconized, these are virgin fibers with silicone coating, which makes the filling slide.
