Yarn Characteristic
Measurement of the total number of fibers extending more than three millimeters from the yarn core indicates the risk of entanglement. Higher levels of s3 hairiness correlate with increased friction and a higher probability of warp clinging in the loom. Measuring this value occurs on an optical tester that counts individual protruding fiber ends.
Mill standards for flax yarn often set strict limits on this parameter to ensure weaving efficiency.
Shedding Impact
Long fibers that protrude from the yarn surface tend to catch on adjacent threads during the vertical movement of the warp. When s3 hairiness is excessive, the shed does not open cleanly, leading to weaving errors like stitches or floats. Effective sizing should lay these fibers flat against the yarn body.
If the size film fails to coat these long fibers, the mechanical action of the loom will tear them away, creating lint.
Surface Finish
Protruding fibers contribute to a fuzzy appearance and a rougher feel in the finished linen fabric. Reducing s3 hairiness during the spinning and sizing stages improves the clarity of the weave pattern and the sharpness of printed designs. Buyers often specify an s3 limit on the quality certificate to guarantee a smooth fabric hand.
