Testing methods
Using a variety of
testing methods, we can offer you the following services:
hvi testing
Our High Volume Instrument Testing (HVI) is capable of providing measurement of the following parameters, as well as standalone testing at a reduced fee:
- length (UHML) and uniformity index (UI)
- micronaire
- strength (g/tex) and elongation
- colour (reflectance Rd, yellowness +b) and colour grade
- trash (% area, trash count) and trash grade
- short fibre content and maturity index
nep testing
The Laboratory has a nep testing module measuring the number of neps per gram of cotton. A reduced nep count improves the spinning performance and yarn quality.
trash testing
We have a Shirley Analyser that measures the trash content by weight in a cotton sample. This testing method is suitable for merchants and spinners who specify an exact trash content allowance for the shipment in their contract.
stickiness testing
We can also measure ‘stickiness' as a separate parameter. This measurement is used to determine level of sugar content and how sticky the cotton is.
micronaire
Micronaire testing can be conducted on either the HVI or the Sheffield Micronaire Tester. Comparisons between the two instruments show that the results are correlated.
afis
Our Advanced Fibre Instrument System can analyse the physical properties of single fibres.
