FibreTQS is an advanced On-Line monitoring system that has been jointly developed for the BCF process by Oerlikon Neumag and OERLIKON Fibrevision. FibreTQS provides measurement of all key quality parameters, with simple operation resulting in real time confidence in yarn quality.
FibreTQS Sensors
The FibreTQS system monitors all aspects of BCF quality with a multi function sensor comprising; an advanced optical sensor and an ultra high frequency tension sensor, providing direct measurement of yarn quality, allowing easy interpretation by laboratory and operating staff. The key quality measurements are:
- Crimp Modulus a direct measurement of the bulk level of the yarn, one of the most important aspects of BCF Quality. The Crimp Modulus measurement is based upon sophisticated analysis of a high frequency measurement of the tension in the winding area of the BCF machine
- Winding tension this affects package build quality, but is also an indication of yarn quality, especially if there are large variations between threadlines.
- Interlace Level is a vitally important aspect of the BCF process, in multi coloured yarns the interlace level has a major influence over the appearance of the yarn.
- Broken Filaments and Slubs have a major impact on the quality of the BCF yarn, but equally important they indicate process problems that can result in a high break rate with resultant efficiency loss. The BROKEN FILAMENT measurement is based on an ultra high frequency measurement of the data from the optical sensor and provides separate data on the number of Broken Filaments and Slubs per package.
Ease of Use
Due to the high production rate and frequent merge changes, the BCF process has special requirements in ease of use and the setup of package grading.
FibreTQS is optimised to address these requirements. Oerlikon Fibrevision and Oerlikon Neumag have developed an automatic grading system using package average data. This involves the key quality measurements being assessed against automatically generated GLOBAL and INDIVIDUAL THREADLINE LIMITS:
This ease of set up, together with LED indication of Doffed Package Quality at the winder, allows immediate identification and segregation of faulty packages
