MICROWEB UD-G
Model – standard
Ultra-dense micro-knit for cleaning smooth surfaces
This wiping cloth is knitted on a circular knitting machine
using bicomponent filament yarn. The single fibrils are
so thin that 1000 km of them weigh only 12.5 g. Next,
following the knitting, the material is shrunk by about
40% in a chemical process. The result is an extremely
dense cloth with outstanding cleaning efficiency. After
the shrinking process, this extraordinary material has a
density of approximately 13 000 filaments per cm².
The MICROWEB UD-G wiper is mainly used for the
time-saving, residue-free removal of thin layers of
grease from glass and ultra-polished surfaces. The
wiper can also remove submicron particles from such
surfaces. Although in its unwashed state the wiping
cloth contains relatively few particles, it may be
submitted to a decontamination process to meet
extremely high standards of cleanness. Due to
laser-based formatting, the surfaces and edges are
in a state of equilibrium in purity.
This image taken with our scanning electron microscope
distinctly reveals the extremely high fibre density of this
top-quality knitted fabric. The bicomponent yarn with the
orange profile consists of a polyamide matrix with
embedded polyester segments. Next, in a chemical
process, the polyamide and the polyester segments are
separated from each other. The result is a multifilament
yarn in which each single filament has several fibrils.
Because the “feel” of the textile is determined by the
amount of polyester used, the fabricated textile has a
silky character with a surface density unmatched by
textiles with other materials.
