FIBER TESTING

WITH AUTOMATED LABORATORY INSTRUMENTS

LabMaster FIBERMAP tests cotton raw material as well as all intermediate products in the spinning preparation process up to the finisher draw frames. The results can be used for evaluation of bale parameters which are important for laydown selection. Furthermore, the instrument delivers comprehensive data for process control especially with regard to contamination control and sugar stickiness.

FIBER TESTING

The different species of Gossypium – the cotton plant – are native in tropical and subtropical regions around the globe. The plant has been domesticated and cultivated already several thousand years BCE on different continents. It takes around eight to ten month before the cotton is ready for harvest. But after the harvesting the work has just begun: It is still a long way from the cotton field to the clothes, which we wear every day.

importance of Fiber Testing IN THE TEXTILE LABORATORY

As a natural material, cotton is subject to quality variations. As these variations affect the quality of the final product, quality control is important in many stages during the production process. The fiber testing of samples from the cotton bale is crucial. Material costs can reach up to 80 % of the total production cost in textile industry. Therefore it should be carefully checked, if you get what you pay for. In spinning mills different qualities of cotton may be needed, depending on the produced yarn. After delivery of the bales the main cotton fiber characteristics – length, strength, colour, trash and fineness – are tested in the textile laboratory. To produce high quality yarns, the machines in the spinning mill have to be set according to the measured cotton characteristics. In addition, neps, seed coat neps, and trash need to be removed in the preparation process in order to be able to spin a high-quality yarn. Daily quality control in the textile laboratory ensures that the performance of the preparation process results in a sufficient quality.

Another important quality measure of raw cotton is the so-called stickiness – also known as sugar content or honeydew. Honeydew-producing insects are responsible for the stickiness, which can ruin the cotton completely and affects the spinning mill tremendously. The fibers can stick to machine parts and the production will stop. Even one contaminated bale of cotton can cause the production of the whole spinning mill to shut down in a few hours.

Complete Fiber Testing with one Device

Devices for fiber testing are among the basic instruments in a textile laboratory. Fiber testing can be time consuming, as all above-mentioned characteristics have to be measured. Loepfe’s FIBERMAP increases the efficiency significantly. The instrument measures all main cotton parameters in one integrated testing device. In addition, the instrument has a unique feature: It is able to measure the stickiness within the shortest time and absolutely automatically during the standard fiber testing.

Our customers know – with Loepfe their quality is mapped.
