Description

Technical Field

[0001] The invention relates to the technical field of printed cloth, in particular to a self-cleaning printed cloth and a preparation process thereof. Background Art

[0002] Printed cloth is a kind of cloth made through printing and dyeing, usually using printed paper for high-temperature printing and dyeing. It was very popular during the Tang and Song dynasties, and reached its peak during the Ming and Qing dynasties. The patterns on printed cloth are called flower patterns. These patterns have been deeply loved by people in history and are often used as dowry bedding and clothes.

[0003] In order to better clean daily necessities, household countertops, kitchen utensils, etc., people usually use rags to clean the necessities. The rags are usually simple printed cloths. Some detergents are added to the rags when they are used to ensure better decontamination and degreasing effects on the items. However, when using the existing rags, detergents need to be added manually, which requires manual control of the amount of detergent, which easily leads to waste of detergent. Therefore, a self-cleaning printed cloth and a preparation process thereof are proposed to solve the above-mentioned problems. Summary of the invention
