the stickiness of cotton is determined by testing a cotton sample at two or more temperatures . sticky deposits are recorded at a lower temperature , preferably 27 ° c . or 34 ° c ., to detect the trehalulose - rich honeydews droplets . then , the sample is subjected to a higher temperature , preferably 54 ° c ., to detect the non trehalulose - rich honeydew droplets and physiological sugars . by comparing the results at these two temperatures , an accurate grading system for cotton may be produced which can help growers and spinners accurately identify different types of cotton and determine processing problems .
