and objective wool certification services. Major services provided are sampling, testing and certifying the yield, fibre diameter, vegetable matter content, staple length and staple strength of greasy wool before it is sold. Our key services can be...

Staple Length & Strength

Staple Length and Staple Strength of the greasy wool measured prior to processing. Unlike core testing for yield and fibre diameter where bales are sampled using a core tube to cut through the wool in the bale, staple Length & Strength is measured from...

Scoured Wool

is able to perform the certified testing of scoured and carbonised wool for Wool Base, Vegetable Matter Base and Mean Fibre Diameter. A further, separate test called a Condition Test is used to determine the oven dry mass and calculated invoice weight...

Decline in Australian wool production in 2015/16 greater than expected

with smaller declines for finer Merino wool and for Crossbred wool. This resulted in a 0.1 micron decline in the mean fibre diameter for Australia to November. Table 1: Summary of wool production estimates and forecasts for Australia Parameter 2013/14...

Wool production remains down in 2015/16

volumes of wool between 21.6 and 23.5 microns. Volumes of other micron categories mostly fell by around 6%-9%. The mean fibre diameter for Australia to February was 21.1 microns, the same as in 2014/15. Table 1: Summary of wool production estimates and...

Wool production unchanged in 2016/17

Excellent seasonal conditions push Australian wool production higher in 2016/17

There was an increase in the volumes of wool for all micron ranges between 18.6 micron and 23.5 micron. The mean fibre diameter for Australia in 2016/17 to November was 20.7 microns, the same as in 2015/16. Table 1: Summary of wool production estimates...

Australian Wool Production Higher

excellent seasonal conditions. There has also been a significant fall in the volume of 26 to 30 micron wool. The mean fibre diameter for Australia to March was 21.0 microns, the same as in 2015/16. Table 1: Summary of wool production estimates and...

Australian wool production impacted by tough season

Australian shorn wool production stabilises in 2020/21

season. AWTA test data showed that the average yield ended the 2019/20 season at 62.2%, down 0.9% on 2018/19, mean fibre diameter was unchanged at 20.5 microns while staple length increased by 2 mm to 85.6 mm as producers moved away from shorter...

Australian shorn wool production stabilises as fleece weights rise

(which is resulting in longer fleece wool). AWTA key test data from July to November show a year-on-year increase in fibre diameter of 0.2 microns, a 2.9 mm increase in staple length, a 1.3 N/ktex increase in staple strength and 0.8% increase in yield....

Shorn wool production increases due to improved season

some of the increase in staple length can be attributed to delayed shearing. There has also been an increase in mean fibre diameter to 20.8 µm, up 0.2 µm, and staple strength up 1.5 N/ktex to 33.8 N/ktex. Shorn wool production is forecast to fall in...

Shorn wool production moves higher
