Stronger than steel, smooth as spider silk
Man-made fibers such as polymer monofilaments (polyamide) have fantastic properties that allow the creation of new, sophisticated products, such as airbags, climbing ropes, functional clothing or medical products.
The highly demanding performance requirement of polyamide yarns requires meticulous manufacturing and tight quality control. Precise and consistent fiber thickness, as well as strict compliance to the perforation size of the fabric is mandatory. The finest polyamide yarns have a thickness of 0.03mm, or a yarn count of around 10dtex. *)
Continuous quality assurance
A METTLER TOLEDO customer has equipped their in-process control stations with ID30 industrial weighing PCs, XS precision balances and barcode readers. The METTLER TOLEDO Statistical Quality Control software solution FreeWeigh.Net running on the ID30, ensures consistent product quality and supports the optimization of the manufacturing process.
Basically, the operator unwinds a sample of 25 – 100m of the yarn, weighs it on an XS precision balance and extrapolates the reading to 10’000 meters. The result corresponds to the yarn count in dtex.
*) The yarn count expresses the thickness of the yarn, i.e. it indicates the length of the yarn in relation to the weight. Dtex is defined as the mass in grams per 10’000 meters. 10dtex = 10g per 10’000m
