Discuss the main points of using evenness meter
The evenness testing-equipment' target='_blank'>tester is used to test and analyze the unevenness and unevenness of the drawing, thick sliver, and fine yarn processes. It has a high cost performance, modular design, easy operation and maintenance, and test software operation. Convenient, of course, you need to pay close attention to some points in use. Strip uniformity meter use points: 1, textile instrument manufacturers introduce the uniformity of moisture absorption of the sample: In view of the sensitivity of the capacitive strip uniformity meter to the moisture content of the sample, it is necessary to pay full attention to the uniformity of the moisture absorption of the sample. The cleaning of the capacitor plates: the flying flowers between the plates and the stains on the plates themselves will affect the final test results. 2. Moderate and stable tension: Moderate tension is the basic guarantee to ensure that the yarn does not deform, and stable tension will reduce possible additional unevenness to a small value. Sample length: Sample length is to obtain information The basic guarantee of credibility is especially true for spectrograms. 3. The position where the yarn passes through the plate groove: In view of the unevenness of the electric field between the capacitor plates, it is necessary to keep the original shape of the yarn and the position between the plate grooves as much as possible. The development of evenness tester (yarn appearance analysis) introduced by textile instrument manufacturers has decades of history. For various reasons, it is still unable to match the capacitive type. However, because its detection principle is closer to people's sensory effects and has a better correlation with the quality of the cloth surface, from the perspective of controlling the final quality of textiles, the photoelectric evenness meter has attracted more and more attention.
However, textile testing equipment isn't the only producer in domestic, and many people feel that GESTER International Co.,Limited's service leaves much to be desired in terms of functionality and design.
