Polymer fiber and filament physical properties testing laboratory

LLC “DIIF” testing laboratory exercises daily control of produced polymer fiber and filament quality.

Testing laboratory specialists have been controlling quality by means of batch sampling for its production run.

Testing laboratory is fitted up with all modern equipment which makes it possible to exercise highly accurate control of output quality.

Checkout is conducted at three production stages in the following ways:

  1. measuring titer and filament moisture at the formation stage (intermediate control)
  2. testing of filament durability and lengthening at the torsion and drawing stage
  3. testing filament moisture, form defect (be means of putting filament into distilled water) and its length at the cutting stage.

Packing control is undergone at the final stage and includes control of plastic bag soldering, its weight and marking
