Dynamic Moisture Comfort Property of Fine Denier Polypropylene Fabric in Different Wind Speed Conditions

摘要

In order to study the moisture comfort property of fine denier polypropylene fiber fabric in different wind speed conditions, dynamic experiments were performed using Textile-Microclimate Measuring Instrument in climate chamber. The relative humidity variation curves of inner and outer surfaces of test fabrics were tested and the comprehensive index was introduced to evaluate fabric's dynamic moisture comfort property. Results show that under four different environmental wind speed conditions, the dynamic moisture comfort property of fine denier polypropylene fiber fabric is much better than other fiber fabrics. In addition, grey mathematics theory was introduced to establish models to predict dynamic experiment's results using static descriptive parameters. Four prediction models of dynamic comprehensive index were established and the predictive precision is much higher.
