Testing Methods

Using a variety of testing methods, we can offer you the following services:

HVI Testing

Our High Volume Instrument Testing (HVI) is capable of providing measurement of the following parameters, as well as standalone testing at a reduced fee:

  • Length (UHML) and Short Fibre Content
  •  Uniformity Index (UI)
  • Micronaire Strength (g/tex) and Elongation and Maturity Index
  • Colour (reflectance Rd, yellowness +b) and Colour Grade
  • Trash (% area, trash count) and Trash Grade
  •  Nep Testing

Stickiness Testing

ICA Bremen is a Centre of Excellence for cotton stickiness testing, providing comprehensive expertise and state-of-the-art testing solutions for the textile industry.

In addition to standard stickiness assessments, ICA Bremen offers stickiness measurement as a separate testing parameter. This can be determined using both thermomechanical and established stickiness testing methods, ensuring reliable, internationally recognised results.

With the addition of the new Contest-S, featuring advanced thermomechanical stickiness measurement technology, ICA Bremen now provides even more accurate, efficient, and sustainable cotton stickiness testing. This latest innovation further strengthens ICA Bremen’s position as a leading reference centre for cotton stickiness measurement.

Gravimetric Trash Testing

We use the Premier G-Trash Tester to accurately determine the trash content by weight in cotton samples. During the testing process, trash particles are mechanically separated from the cotton, collected, and weighed to calculate the percentage of trash content. This method is particularly suitable for merchants and spinners who specify a maximum allowable trash content in their purchase contracts, providing precise and reliable results to verify compliance with quality specifications.

In addition, the MAG Accu Trash system can distinguish between trash, dust, and fibre fragments. A high-speed licker-in roller individualises the cotton sample, effectively separating trash particles from the cotton lint. To minimise testing variation, three subsamples of approximately 10 grams each are prepared from the original sample and tested individually. During the process, the cleaned lint is collected in a separate lint box, while the trash particles are collected on a tray. The trash particles are then weighed automatically, and the trash content is calculated as a percentage of the original sample weight.

Micronaire

Micronaire testing can be offered as an independent sub-measurement and is available as a separate testing service.

AFIS

Our Advanced Fibre Instrument System can analyse the physical properties of single fibres and is especially used to determine the nep content.
