With RUNOFF, test parameters such as slope angle, dosing volume and liquid discharge time can be individually adjusted. The Test principle of RUNOFF enables the runoff test to be performed either as a basic test or as a repeated test, according to the specifications of INDA/EDANA.
Cost savings
A collecting container is used for collection of the run-off liquid instead of a receiver pad. This means less need for consumables and therewith cost savings.
Test method
A specified quantity of test liquid (simulated urine) is automatically discharged at a constant rate onto the test specimen, which is positioned on an inclined plane. After the test liquid has penetrated into the absorbent medium underneath the test specimen, the non-absorbed run-off liquid is discharged into the collecting tray; the operator weighs the tray and notes the run-off value.
Standardized according to INDA/EDANA WSP 80.9.
Efficient quality control
Labour- and time savings: A high number of bobbins/packages can be tested for draw tension/draw elongation, titer/titer variation and/or interlaced knots/entanglements shortly after completed production. The fully automatic testing- and sample feeding procedure eliminates the need for any assistance of the operator, who is free to carry out other tasks.
Fast reactions to quality deviations
SESS and the connected instruments are positioned at-line in the production; hence the bobbins can be controlled for their quality directly after completed production. This enables prompt reactions to any deviations from set quality levels.
Flexible integration
SESS is designed for flexible integration in all levels of transport systems and automation.
Function
The SESS Sequential End Sampling System facilitates sample feeding to Lenzing Instruments’ high volume testing instruments ACW 600/DVA, DTI 600 and/or RAPID 600 V. SESS can be combined with one or two of the testing instruments and up to 24 bobbins are managed fully automatically by the system. All yarn ends from a shuttle, buggy or creel positioned in front of SESS are subsequently guided and fed to the connected instruments on a pneumatic air stream. The measurement of the yarn ends on the selected testing instrument is accomplished fully automatically according to a pre-set schedule. Generated measurement results are presented on the connected testing instrument.
Automatic testing
After sample preparation, the test is performed fully automatically. The automatic and standardized test procedure guarantees for objective test results with high reproducibility.
Up to three samples of nonwovens may be tested simultaneously during one and the same test run.
Easy operation
SLOSH BOX 100 features easy and ergonomic handling.
Test method
The Sloshbox Disintegration Test simulates the behaviour of a nonwoven product in a gravity sewer. The objection is to analyse the potential for a product to disintegrate when it is subjected to mechanical agitation in water. During the test procedure with SLOSH BOX 100, the water-surrounded nonwoven sample is exposed to mechanical oscillations for a time period of one hour. After the test, the size of the residual fragments provides information about the flushability of the material. A standard analysis sieve is included.
SLOSH BOX 100 performs the Slosbox Disintegration Test according to FG502 of INDA/EDANA guidance document for assessing the flushability of nonwovens.
Enhanced fiber quality
By integrating TALI 400 B in a closed control loop, fully automatic dosing of chemicals is possible. The automatic dosing guarantees for constant bleaching bath concentration. Constant production conditions mean constant quality in terms of elongation, crimp etc.
Cost savings
The controlled bleaching bath concentration enables optimised consumption of chemicals and the associated cost savings.
Test method
The monitoring of concentration variations in the bleaching bath is based on the principle of acid-base titration. An alkaline solution is added to the acid solution by means of titration until the pH value rapidly changes from a low to a high pH value. The rapid change in pH value indicates that the equivalence point has been reached between the acid and the alkaline solution. This allows for calculation of the concentrations of NaOCl.

Therewith, VIBROTEX 400 meets all requirements of fiber producers for accurate, flexible and thorough analysis of the crimp characteristics of staple fiber.
Quick feedback
Test results availability within seconds for quick reactions to quality levels and possible deviations from set quality levels.
Test method
Electromagnetic clamps fix the pre-tensioned fiber at top and bottom. The fiber is automatically drawn to carefully remove the crimp to a predefined extent. After the fiber has been straightened to the predefined trip level, the bottom clamp changes direction towards relaxation of the fiber. This means that the crimp removal is stopped before the crimp is pulled out completely. The applied algorithm allows for extrapolation up to the standard crimp removal of 1 cN/tex. For handling purposes, pretension is accomplished by means of paper weights. The usage of light paper weights for pretension prevents the crimp properties from being affected by the pretensioning. Years of profound research has proven that the applied tension limits of the measurement procedure do not influence the crimp during the test.

Standard setting
Lenzing Instruments is official partner of INDA/EDANA for the wetback measurement.
Supplier of filter paper
The needed standardized filter (blotter) paper can be acquired from Lenzing Instruments.
Test method
The WETBACK test is performed in connection with a liquid strike-through test with LISTER AC. Subsequently, a defined amount of liquid is applied on the prepared sample consisting of a nonwoven coverstock placed on top of a standard absorbent medium. Thereafter, the integrated simulated baby weight of WETBACK is automatically lowered onto the specimen. The lowering of the baby weight is accomplished with an by INDA/EDANA accurately defined speed. The weight remains on the sample for a specified period of time to ensure even spreading of the liquid. A pre-weighed special filter paper i.e. pick-up paper is then placed onto the nonwoven coverstock and the weight is again lowered onto the specimen. Consequently, by means of an electronic balance, the amount of liquid is determined, which, due to the load, is passed back through the specimen’s surface into the pick-up filter paper. The weight of the liquid absorbed by the pick-up paper is defined as wetback.
