What is uster classimat:
The introduction of Uster classimat in 1968 has revolutionized the quality of yarn production and commercial checking and quality assurance. Models of later versions of Classimat have further expanded its field of application. Currently, Usterclassimat is recognized worldwide as a method of classifying yarn. The usterClassimate can be used to check the two types of yarn, Cleared and Uncleared, by sorting the yarn into Thick and Thin places, and also to check for the rare errors. https://bdfabric.com/quality-control-activities-for-apparel-manufacturing/
Yarn irregularity can be broadly divided into two categories. E.g.
1. Frequently occurring fault
2. Seldom occurring faults
1. What is uster classimat-Frequently occurring fault:
Such defects are seen again and again in the yarn. This reorganization error is Thick place, thin place, and Naps. Such errors are more or less than the average value of the yarn. Yarn thick and Thin Places are usually for drafting. Naps are usually made for Immature Fiber and Carding. Such defects in the yarn are usually analyzed by uster Evenness Tester and Accessories. https://bdfabric.com/operations-for-controlling-fusing-in-garments-industries/
2. Seldom occurring faults:
Faults in the yarn that do not recur frequently occur, that are seldom occurring faults. Such defects are slub, Thick places of different range, thin places of different range. This type of yarn defect is usually subtly examined using the uster classification method. The faults are divided into 16 grades based on the length of the faults and the weight of the unit length of the faults.
If the yarn passes through the sensing capacitor to the faults, then the length of the fault and the weight of the unit length of the fault are observed and classified according to the grading system. Uster-classimat is a Yarn testing instrument that examines the yarn and classifies the yarn defects by classifying them according to the length of the error and the weight of the unit length. The uster Classmate consists of 4 basic parts.
1) Sensor /E.Y.C.
2) Evaluation unit
3) Control panel
Uster classmates usually have 6 sensing units, each of which is connected to a winding head. Each of these units is associated with a classifying unit. The test data is stored on the same counter throughout the unit. This instrument is displayed on 16 counters. Each counter displays the length of the yarn error and the weight of the unit length differently.
