Characterization of Porel Fiber Structure and Thermal-Wet Comfort of its Fabrics

In recent years, consumers have higher requirements for the thermal comfort of clothing. Porel (a new generation of cotton-like cationic dyeable polyester staple fiber) was developed to expand the development of thermal and wet comfort fabrics. In this work, the development process of cationic modified polyester was reviewed, and the characteristics and properties of Porel fiber were introduced. The permeability and quick-drying performance of knitted fabrics were analyzed; thermal-wet comfort of Porel denim and cotton denim woven fabrics performance was compared. In addition, the hygroscopic and heating properties of various knitted underwear fabrics were also tested. The results showed that the quick-drying performance of Porel knitted fabric was 23% higher than that of cotton fabric, and the moisture permeability index is 0.34 higher than that of cotton fabric and Coolmax fabric. Besides, Porel denim fabric improves moisture conductivity by 14.17% compared to cotton denim. Last but not least, the maximum and average temperature rise values of Porel knitted fabrics are 4.40℃ and 3.49℃, respectively, which meets the requirements of hygroscopic heating knitted underwear standard.
