Acetate Tow Moisture

Why Measure Moisture Content?

Because of its hydrophobic properties, it is essential to control acetate tow moisture to ensure that the final filter product will readily absorb moisture during its use without sacrificing the required uniform pressure drop. MoistTech’s  IR-3000 moisture sensor allows producers to monitor acetate tow moisture throughout production.

Understanding the acetate tow production process—unwinding and shredding cellulose fiber, acetylation, hydrolysis to the secondary acetate, flaking, and final conversion to fiber—and how the moisture of the final tow is affected at each point in the process has allowed MoistTech to develop a superior moisture sensor for the acetate tow producer.

Cellulose acetate tow is a synthetic fiber produced by extruding cellulose acetate flake. In contrast to traditional plastics, it does not rely on fossil fuels. Both cellulose acetate tow and cellulose acetate polymer are derived from cellulose, which is the most prevalent biopolymer globally and is sourced from renewable non-food materials.


Our equipment never comes into contact with the product, allowing for less waste

zero drift

Our sensors are guaranteed not to drift over time – which saves time and money

closed loop

Create a closed-loop process by tying a moisture sensor into your PLC. Full control over the line!

no recalibrations

We’ve mastered the art of moisture sensors – your unit will never need to be recalibrated for the same product twice!

Productive Solutions

The IR-3000 was designed and built to require nearly no maintenance or calibration. Sensor calibrations, measurement wavelengths, algorithms, and sensor optical requirements measuring acetate tow moisture have been pre-set at the factory.

Designed and built to perform in the harshest industrial environments, it is impervious to:

  • Acetate tow fiber size
  • Tow fiber color
  • Tow temperature
  • Ambient temperature or humidity
  • Foreign and inert objects within the sample
  • Fiber dust
  • Gaps in product flow

Installation Points

The IR-3000 moisture measurement system can be installed to capture thousands of moisture measurements per second along belt, screw, and drag conveyors, in down chutes, inside storage bins, and in fluid-bed dryers. This versatility allows producers to control moisture at nearly every point in the acetate tow production cycle.
