Surface Energy Modification
Standard polypropylene spunbond is naturally hydrophobic, repelling water due to low surface energy. For hygiene, medical, and agricultural applications requiring rapid fluid transmission, surface tension modification via surfactant application converts the non-woven into a high-performance hydrophilic barrier.
Contact Angle Analysis
Liquid contact angle measurement determines wet-out dynamics. Jayashree Spunbond's hydrophilic treatments achieve strike-through times under 3 seconds, ensuring zero liquid pooling while maintaining tensile strength across both machine and cross directions.
Industrial Applications
Hydrophobic non-wovens serve as barrier leg-cuffs, surgical drapes, and outdoor protective covers. In contrast, hydrophilic variants are selected for top-sheets, medical wipes, and capillary agricultural irrigation blankets.
