< p > > a href= "http://m.pmae.cn/news/index_c.asp" > Zurich < /a > (rs/ab) - TESTEX focuses on more sophisticated testing equipment.

The quality of yarns is further ensured by using the Ulster 5 tester in physical testing laboratory.

< /p >

< p > evenness is one of the most important criteria for identifying single yarn and < a href= "http://m.pmae.cn/news/index_c.asp" > strand quality < /a >. Its value depends on the number of yarn length, nep and yarn hairiness, so these parameters are the key criteria affecting the appearance uniformity of finished fabrics.

< /p >

The above 5 important yarn parameters are detected by adopting the most advanced < a href= "http://m.pmae.cn/news/index_c.asp" > < /a > P.

< /p >

Below P, these sensors recorded different yarns: < /p >

< p > OH optical sensor for detecting yarn hairiness < /p >

< p > CS sensor detects quality variation of capacitance sensor < /p >

< p > OM sensor optical sensor for detecting yarn shape and cross section changes < /p >

< p > FM sensor for impurity detection < /p >

< p > in addition to using capacitance sensor to detect yarn quality variation, optical sensors are used to detect yarn diameter, density and roundness.

For example, if the two yarns have the same number of fibers and different yarn twist on the cross section, although the yarn is of the same mass, it may have a completely different appearance.

The impurity sensor can detect coloured fibers from light colored yarns, and can also detect dark colored fibers, plant fibers and cottonseed chips.

< p > if the detected sample does not have a defined reference value, the parameters obtained after the sample will be automatically compared with the reference values in the USTER statistical database.

< /p >

< p > to visually reflect the effect of yarn test results on the final product, the display screen will display not only the results of the test data and the analysis chart (Figure 2), but also the yarn, knitted or woven fabrics that are simulated according to the data.

This analysis method can get a lot of information, especially when detecting unconventional yarn or cyclical defects, the results will be quite intuitive.

< /p >

< p > through the use of the Ulster 5 type bar tester, TESTEX will contribute to the improvement and perfection of yarn quality with reliable and modern yarn detection equipment.

< /p >

Like all other yarn detection equipment, the Ulster 5 type tester is involved in the two times of "yarn cycle contrast test" a year, compared with other participants in the P test.
