Against this backdrop, the integral role of cotton as a pivotal component in the realm of atomization is increasingly underscored. Commencing with its original mission to prevent oil leakage, the focus has gradually shifted over time and through successive product iterations, with a growing number of manufacturers prioritizing the enhancement of cotton's low-residue performance and the improvement of the user's sensory experience.\n<\/p>\n<p>\n\u00a0<\/p>\n<p><strong>Unveiling the Dynamics of E-liquid Transmission within Oil-Absorbing Cotton<br \/>\n<\/strong><\/p>\n<p>\n\u00a0<\/p>\n<p>As elucidated by Professor Huang's team at Donghua University, the interaction between the integrated oil-absorbing cotton and e-liquid mirrors the transmission of water within fibrous textiles.\n<\/p>\n<p>\n\u00a0<\/p>\n<p>Although the composition of e-liquid is relatively complex, its primary constituents, PG\/VG, like water, are polar molecules, rendering water an applicable analogy for reference purposes.\n<\/p>\n<p>\n\u00a0<\/p>\n<p>Given the diversity in the structure and chemical composition of fibers within the fabric, their interaction with water molecules varies, leading to the absorption of water being categorized into three parts: bound water, intermediate water, and free water, as depicted below.\n<\/p>\n<p>\n\u00a0<\/p>\n<p style=\"text-align: center\"><img decoding=\"async\" src=\"https:\/\/www.abesmoke.com\/wp-content\/uploads\/2024\/04\/040724_0950_1.png\" alt=\"\"\/>\n\t<\/p>\n<p>\n\u00a0<\/p>\n<p>Similarly, upon absorbing e-liquid, the integrated cotton wick will also form bound oil, intermediate oil, and free oil.\n<\/p>\n<p>\n\u00a0<\/p>\n<p>During the vaporization process of electronic cigarettes, if certain constituents of the e-liquid form exceedingly tight \"bound oil\" and \"intermediate oil\" through hydrogen bonds or intermolecular forces with the fibers, it results in impaired e-liquid delivery, leading to issues of high residue and low fidelity.\n<\/p>\n<p>\n\u00a0<\/p>\n<p>The transmission of e-liquid within the integrated cotton primarily comprises two components:\n<\/p>\n<p>\n\u00a0<\/p>\n<ul>\n<li>\n<div style=\"text-align: justify\"><span style=\"font-size:10pt\">One portion moves downward, i.e., along the axis of the fibers, fundamentally relying on capillary action, and since synthetic fibers generally lack pores, transfer mainly occurs through the narrow gaps formed between fibers.
