Qualitative Classification of Cotton Stickiness in the H2SD High Speed Stickiness Detector

Regularly confronted with the problem of cotton stickiness during spinning, those in the international market wish to see the implementation of a cotton bale classification system to describe the degree to which a given cotton is contaminated. Thermodetection equip ment such as the H2SD high speed stickiness detector may be suitable for such a task. With a working capacity equivalent to that of HVI lines, this instrument evaluates the stickiness of cottons contaminated by insect honeydew. This paper discusses the feasibility of a qualitative classification based on within-bale distribution of the number of sticky points. A detailed example obtained with the H2SD illustrates the qualitative classification proce dure. Sticky bales can be separated from uncontaminated bales for the latter to be marketed with a guaranteed stickiness level below a set threshold and a litigation risk selected in advance.
