Textile / Fibre Industry: Spin Finish Determination

Finish on Fiber (FOF), Oil Pick Up (OPU), Avivage

Spin Finish is added to various fiber during production to improve downstream handling. This way, static electricity and sufficient lubrication are effectively avoided and guaranteed, respectively.

Clearly, the amount of Spin Finish has to be tightly controlled. To this end, a bias-free, non-destructive as well as speedy and reliable method is needed. the minispec mq-one Spin Finish Analyzer is the perfect choice meeting these demands and exceeding customer's expectations.

Spin Finish Application: Proven for Any Fiber

Bruker together with partners have developed this minispec TD-NMR method in the 80ies. Since that time the minispec Spin Finish method has proven successful to virtually any kind of fibers, as there are:

Technical fibers
Textile fibers
Multifilament, monofilament, staple fibers
Texturized fibers
Fibers and Yarns made out of: Polyester, Polyamid, Polypropylene, Polyethylene, Polyacrylonitrile
Nonwovens made out of: Polypropylene, polyethylene

Spin Finish Methods: Weighless and Weighing

Time is money, in other words, the fewer steps a method requires, the better. Bruker's mq-one Spin Finish Analyzer offers the method referred to as Weighless Method. This method consists of only one measurement step.

The Weighing Method is of course offered as well if ultimate accuracy and precision are required. This method takes the sample weight into account as well.

As the table below indicates, both methods have their particular advantage. Because of this, both the Weighless and the Weighing Method are offered with every mq-one Spin Finish Analyzer.
