Problems solved by technology

Sebum-contaminated cloth is used as a standard substance for evaluating the cleaning performance of washing machines on oily dirt. In the existing standards, there is a problem that the production process of the contaminated cloth is not standardized, which will cause the properties of the finished contaminated cloth to be unstable, and the reject rate is high. The cloth rate is low, which seriously affects the accuracy and reproducibility of the washing machine performance test results

Abstract

The invention relates to a manufacturing process of contaminated cloths, in particular to a manufacturing process of a sebum-contaminated cloth for evaluating the cleaning performance of a washing machine on oily dirt. In the manufacturing process, water is used as a production solvent for preparing the pollution liquid, unsaturated fatty acid, olive oil and wax (liquid paraffin) are used as mainoil components, a rolling suction tentering setting machine is adopted for printing and dyeing, and manual intervention in the printing and dyeing process is reduced by controlling the pressure of a padder, the drying temperature of a dryer, the air volume of a fan, the chain rate and the like, and the automation degree is high. The reflectivity of four points on the two sides of a sebum-contaminated cloth finished product prepared by the process is between 22% and 28%, and the rate of finished products can reach more than 90%.

Description

technical field [0001] The invention relates to a manufacturing process of a contaminated cloth, in particular to a manufacturing process of a sebum contaminated cloth used for evaluating the cleaning performance of a washing machine on oily dirt. Background technique [0002] Contaminated cloth is a standard material to measure whether the washing machine can wash clothes, and it is also a standard material used in the internationally accepted washing machine performance test method. Sebum-contaminated cloth is used as a standard substance for evaluating the cleaning performance of washing machines on oily dirt. In the existing standards, there is a problem that the production process of the contaminated cloth is not standardized, which will cause the properties of the finished contaminated cloth to be unstable, and the reject rate is high. The low cloth rate seriously affects the accuracy and reproducibility of the washing machine performance test results. [0003] Theref...
