Loepfe Brothers unveil OffColor detection in yarn clearers
Loepfe Brothers Ltd., manufacturer of sensors and monitoring equipment for yarn spinning and fabric weaving processes, has launched the new optional feature in the yarn clearer YarnMaster ZENIT+, the OffColor detection. The OffColor detection is able to detect and eliminate very small colour and shade variations in the yarn during the winding process.

Mélange yarns and colour-effect yarns are a growing trend in the garment industry. In order to have an optimum mélange yarn, the fibres have to be mixed carefully in the right proportions at the beginning of the spinning process. Even small shade variations or colour deviations of the yarns may result in poor quality of the fabric after knitting or weaving.

Another common reason for poor quality can arise during the winding process, where bobbins with similar looking colour or shades are accidentally mixed up. Even small variations in the shade of the yarn, which cannot be detected by the human eye when looking at the bobbin, can result in poor quality.

Complaints about yarn quality can be expensive for the spinning mill. To guarantee high quality even in this difficult field, Loepfe offers OffColor detection in the yarn clearer YarnMaster ZENIT+. The new feature uses the F-Sensor, which is already integrated in the YarnMaster ZENIT+. Therefore spinning mills, which already use the yarn clearer for quality control during winding, can update their devices with this new functionality.

The new OffColor detection has been extensively tested with a large number of bobbins with mélange yarn. The bobbins, which have been made available by a customer, had the same colour, but small shade variations as the black portion of the mélange yarn varied slightly from dark to light grey. During the test runs, which have been conducted at Loepfe ´s headquarter in Switzerland, the YarnMaster ZENIT+ with the new optional OffColor feature was able to detect even the smallest shade variations very reliably. All other functions of the yarn clearer have been disabled during the tests.

The new feature does not depend on the colour of the yarn. In addition to the tests conducted at Loepfe’s headquarter, some clients have already tested the new functionality during normal operation in the spinning mill. These clients confirm that the OffColor feature works absolutely reliably and clear yarns of wrong colours or shades during the winding process. Between 10 per cent and 15 per cent of the spinning mills actually produce coloured yarns or mélange yarns. (GK)
