Benefits for the Fiber Industry
Fast and Reliable Quality Control
Bruker
offers fast and reliable solutions to measure Spin Finish directly on fibers. Spin Finish avoids static electricity,
guarantees sufficient lubrication and improves the cohesion of filaments. Thus, the properly coated fiber runs
more smoothly through the spinning machines, allowing faster and more reliable operation. Even non-woven fabrics
benefit from the Spin Finish for its improvement of handling and functional properties. Bruker’s versatile TD-NMR
method is capable of determining the amount of Spin Finish. The remarkable accuracy, reproducibility and repeatability
of Bruker’s minispec further allows for studying of the distribution for the Spin Finish content on the fibers,
especially for very low Spin Finish concentrations (<0.1%).
The
Range of Applications
Spin
Finish determination, also known as Oil Pickup (OPU), Finish on Fiber (FOF), or
Finish on Yarn (FOY), can be determined for practically all combinations of fibers
and spin finishes. Based on longterm experience, it is suited for
?
technical textile and high performance fibers
?
multi-filament, monofilament, staple fibers,
non-woven fabrics as well as texturized samples
?
polyester, polyamide, polypropylene, polyethylene,
polyacrylonitrile fibers and yarns
The
Spin Finish Applications
Bruker
offers both weighing and nonweighing methods:
Non-Weighing
Spin Finish Method (medium to high Spin Finish levels)
?
High sample throughput
?
Fastest sample preparation
Weighing
Spin Finish Method (very low to high Spin Finish levels)
?
Highest accuracy and repeatability
?
Special application: Check that Fibers are Spin Finish Free (very low Spin Finish
levels for applications where Spin Finish is unwanted)
?
Monitoring of fiber washing
Beyond
Spin Finish Application
DIP
(Polymer Coating) on Fibers
For
specific high performance applications, polymer coatings, so-called DIP, are added to the fibers, e.g. for high performance
car tires.
?
Polymer quantification
?
Polymer coating thickness evaluation
The
Key Advantages
Bruker’s
minispec offers many advantages over competing analytical methods like wet chemical analyses, gravimetry and near infrared
(NIR).
Fast
and accurate
The
analysis delivers reliable results in less than 60 seconds. It is 2-3 times more accurate than any classical wet chemical
method. The system offers the highest repeatability and ultimate reproducibility, especially compared to wet chemical approaches
and NIR.
Measurement
of the sample as is
The
analysis requires simple, minimal sample preparation. Moreover, it is color and surface independent and all of the sample
volume is measured.
Fast
and convenient calibration
The
system runs with a minimum of calibration efforts. Only 3 to 5 samples are required to set up a calibration in
form of a linear regression.
Safe and efficient
The TD-NMR analysis provides workplace safety as well as
reduced labor costs. It avoids the use of solvents which is beneficial for the operator’s health and the environment.
Fiber
use is very broad. For example, they are utilized in the textile industry for clothes and carpets. They are also found in a broad
variety of everyday products like toothbrushes, car tires, car seats, air bags etc.
