Yarn hairiness denotes the amount of hairs (fibres) protruding above the surface of the textile yarn. Especially, in case of staple spun yarns, since multiple fibres are bound in a single yarn, fibres will tend to protrude outside the body of the yarn even though proper twisting is done for that yarn. Usually Hairiness is denoted in terms of the parameter "Hi", which means "Hairiness Index". It represents the total length of hairs (in cm) measured over the yarn length of 1 cm. Another way of representing Hairiness is "Hair Count". It represents the number of hairs counted for a given length of yarn. It varies from 3mm to 10mm. Longer Hairs are problematic compared to shorter hairs. Shorter hairs are essential for yarns to provide comfort for fabrics. In new generation testers, a new parameter called "Hair Severity" is available which represents the severity of longer hairs. This number will indicate the influence of hairs in further processing like weaving and knitting. Latest generation yarn testing equipment by PREMIER offers all these parameters.

What is definition of yarn hairiness index?
Hairiness is measured in two different methods.Uster Hairiness IndexZweigle Hairiness Index1. Uster Hairiness Index: - This is the common method followed in India. The hairiness index H corresponds to the total length of protruding fibres within the measurement field of 1cm length of the yarn.2. Zweigle Hairiness Index: - This zweigle hairiness measurement gives the number of protruding fibers more than 3 mm in length in a measurement length of one meter of the yarn.From the above we can infer that Uster hairiness index give the total length of hairs whereas zweigle hairiness testers give the absolute number of fibers. Though the later measurement is more accurate, most of the Indian spinners are still following Uster hairiness index only.
72F of yarn count?
The first number of a yarn count (D) generally indicates the fineness of the yarn (how thick it is). The second number (F) indicates the fluffiness or hairiness of the yarn. The last number indicates the number of plies in the yarn. Example: 75D/72F/2 is a 75 denier (75 g/9000m), 2-ply yarn with a hairiness or fluff index of 72. The fluff index becomes important in weaving where it can change the optical effects of the woven fabric. There are several different systems for measuring yarn hairiness. The F-index method appears to be from a patented Japanese method of measurement.

The Siro process makes it possible to produce a directly weavable two ply yarn, directly at the ring spinning machine, so eliminating the usual twisting process. From this you get yarn strength, a smooth yarn, minimal hairiness and round yarn cross section
