Quality Control Solutions for Manufacturing of Fibers and Non-Woven Fabrics
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.
