What is (SFI) Short Fiber Index In cotton HVI report.

SFI Short fiber index is a very important parameter in cotton results as it determined the ratio of short fiber in cotton. SFI indicates the %age of fiber having less than half inch length. This ratio is counted on High Volume Instrument HVI, one of the latest and best cotton testing instruments being used in the textile sector. The higher SFI is usually considered bad in cotton results.

SFI below 6.00 is an indication that cotton has very less short fiber which is good for cotton consumers. But this sort of cotton is rarely available.

Normally and mostly cotton contain SFI between the range of 6 to 9 and it’s acceptable for most cotton buyers.

SFI short fiber index from 10 to 13 is considered a little higher side ratio but to some extent acceptable for the cotton consumers.

SFI short fiber index above 14 is usually not acceptable for yarn manufacturers who want to make fine quality yarns and they avoid buying cotton with such high value of SFI.
