Cotton for High-Tech Spinning - What Does the Spinner Expect from HVI?

Helmut Deussen


Spinners worldwide are very interested in cotton quality measurements from HVI systems. The need for assessing additional properties on HVI, such as fineness, maturity, short fiber content, and stickiness is explained. The confusion among spinners, particularly overseas, created by different methods of testing fiber strength calls for standardization, in addition to greater accuracy and repeatability. Of the two available methods to express fiber length and length distribution, the one best suited to predict processibility should be selected as standard. A better expression of short fiber content or a length uniformity index seems essential. To satisfy all concerned, the HVI system should be further refined, expanded, perfected, and standardized, using standard sets of calibration cottons. The delivery of better quality cotton for the domestic industry and for a growing export business should be accompanied by reliable fiber property descriptions from HVI. Finally, complete and accurate HVI data must be the basis of a new classing and marketing system.
