In the detection of the oil content of the polyester thread, we can use the affinity of the detergent and the oil agent to transfer the oil on the sample to the detergent liquid under the action of the washing power, according to the sample before and after washing. The mass change is calculated and the oil content of the sample is calculated. Please indicate the source.

First, prepare reagents such as detergent and tap water. Then there are instruments and tools, such as weighing containers: petri dishes, balances, ovens, dryers. Finally, the sample preparation requires two samples per roll of polyester yarn, and the length of the sample is 100 meters. Once these are ready, the test steps will begin.
Before starting, the mass of the sample is measured, and the mass m1 of each sample is weighed before washing. After weighing, wash it, put the polyester thread sample into the beaker, add three drops of detergent to each sample, then pour 200 ml of hot water above 80 °C, stir with glass rod for at least 1 minute. Rinse the detergent with tap water, wring it out and place it in a Petri dish, then dry it in an oven at 105 °C ± 5 °C for 90 minutes. Finally, take out the sample and put it in the desiccator. After room temperature, weigh the sample and record it as m2. After that, the results can be obtained by calculation based on the obtained data.
