Laboratorium Pad-Steam unit Werner Mathis PSA, made in year 1977
Mathis Laboratory Pad-Steam Range Type PSA
Laboratory pad steam range type PSA is made for continuous and
practice-oriented operation for steaming and after-treatment of a pad
steam process. The range is especially suitable for treating of
cotton, cotton-synthetics, polyacrylnitrile, as well as viscose
fibers.
The dyestuff application is done at the two-roll vertical padder. The
pneumatic load transmission and the equal shore hardness of both
rollers guarantee a uniform pick up. Two dye troughs of different
sizes allow following applications:
- larger trough for long samples,
- smaller, easily removable trough for short samples and
- trials in series with a large selection of dye shades.
The material is impregnated with chemicals in the dip trough, which is
placed in front of the steamer. A driven squeezing device with
pneumatic cylinders determines the pickup. The arrangement of the
squeezing device and chemical trough permit a fast entry into the
steaming chamber, which is especially favorable at low fabric
speeds
An absolutely air free steaming atmosphere is required for an optimum
dyestuff fixation.
Trials with saturated steam or with slightly overheated steam up to
115°C are possible by means of a temperature regulator.
An inspection window allows to observe the material during the
steaming process. Perfect heat insulation is guaranteed by the
double-walled construction with insulation in between.
All inner parts of the steamer are made of acid resistant stainless
steel AISI 316
For the after treatment of the dyed goods, there are wash troughs with
a material content of 1m, 2m, or 4m available. Each wash trough can
individually be heated with direct steam and hand valve or automatic
temperature regulator.
