Shrinkage measurement
Limiting shrinkage during washing or cleaning of textiles is essential. To control shrinkage, it is important to monitor how much shrinkage occurs during your cleaning process. CCD’s Industrial Shrinkage Monitor (ISM) helps you do just that.
- Objectively assess shrinkage during the washing process
- ISM-C for cotton
- ISM-W for wool

Shrinkage measurement with the Industrial Shrinkage Monitor (ISM)
Limiting shrinkage during washing or cleaning of textiles is essential. To control shrinkage, it is important to monitor how much shrinkage occurs during your cleaning process. CCD’s Industrial Shrinkage Monitor (ISM) helps you do just that.
Types of shrink monitors
Two types of the ISM are available: the ISM-W1 and the ISM-C1.
ISM-W1
Designed to the standard of the International Wool Secretariat, the ISM-W1 consists of a set of three wool cloths. Each cloth shows a blue woven square containing a CCD stamp (see illustration). This stamp helps measure horizontal and vertical directions.
To measure shrinkage, the three cloths are co-cleaned in the cleaning process to be checked. This can be done once or, for example, 5 to 10 times. After each cycle, measure the distance between the lines in the square. This gives you a clear picture of the shrinkage during the process. The shrinkage percentage is calculated by comparing the measured values with the initial measurements (which you measure beforehand as a 0 measurement).
ISM-C1
The ISM-C1 is based on the international standard ISO 456 and consists of six cotton wipes. Each wipe has a stamped square in which the horizontal and vertical lines measure shrinkage. The six wipes are also co-cleaned one or more times in the washing process to be checked. After each wash, measure the distance between the lines to calculate the shrinkage percentage. This percentage is compared with the baseline values measured as the 0 measurement.
How does measurement work?
The cloths are washed or cleaned one or more times in the process to be controlled. Usually you wash them a maximum of 5 to 10 times. After each cycle, you carefully measure the distance between the horizontal and vertical lines on the cloth. If shrinkage has occurred, this distance has decreased. By comparing the difference with the original measurements, you easily calculate the shrinkage percentage.
The ISM makes shrinkage transparent, allowing you to manage it better and keep your textiles in top condition longer.
