Mass transfer and thermal buffering effect of hydrophobic fabrics with single-side coating of MPCMs

Popis výsledku v původním jazyce

The incorporation of microencapsulated phase change materials (MPCMs) into textiles have been realized for personal temperature regulation. However, the hydrophobicity and breathability of MPCM-incorporated fabrics remained improvement. In this work, four commercial fabrics were first treated with a hydrophobic coating and the MPCMs were coated on the hydrophobic fabrics via pad-dry-curing coating method. The morphology, hydrophobicity, thermal energy storage, thermal buffering effect, moisture transfer, and breathability of the MPCM-coated fabrics were investigated. As a result, the MPCMs were well coated on one side of the hydrophobic fabrics. The water contact angles of the MPCM-coated side of MPCM-coated fabrics were higher than 100o, and the anti-fouling property was found. Besides, the breathability was reduced when an MPCM coating was on the hydrophobic fabric. The one-way moisture transfer behavior was little affected when there was an MPCM coating on the knitted and woven fabrics while significantly reduced when the 3D knitted fabric was the substrate. The thermal energy storage of the MPCM-coated fabrics ranged from 1.89 to 8 J/g, which was related to the used fabric type. Correspondingly, the thermal buffering effect of MPCM-coated fabrics was found, and a better thermal buffering effect was proposed when the MPCM-coated side faced the heating source.
