Fiber disposition

Index

The yarn buyers expect that the yarn they receive is (besides other quality features) even in structure and appearance. However, an even yarn is achievable only by fulfilling some preconditions. These preconditions are very easy to explain, but very hard to obtain: in every yarn cross-section of the whole yarn length there should always be:

  • the same number of individual fibers;
  • the same number of fibers of every group of the same quality parameter (i.e. length, Fig. 51 a/b), fineness, thickness, etc.
