Warp sizing is the most important process of weaving preparation in the textile industry. Permeating and coating ofsizing paste into/on warp yarns directly determine the quality of sized yarns. However, there are many significant drawbacks,such as low accuracy and narrow variety adaptability for sizing agents and warp yarns, in the traditional determinationmethod of permeation and coating property of sizing paste. Focusing on the problem, this investigation introducedaggregation-induced emission (AIE) fluorogen to prepare a fluorescent sizing agent. The interface of sizing agent in textilecould be accurately visualized by AIE fluorogen. The three indexes to indicate the permeability and coating property ofsizing paste, i.e. permeation percentage, coating percentage and integrity percentage of sizing film, have been determinedaccurately and conveniently. This investigation efficiently solves the difficult problem of evaluating permeation and coatingproperty of sizing paste and has a significant guiding function on accurate determination of the quality of sized yarns.
