In this article, equilibrium clamshell shaped drops have been simulated on conical fiber sections via finite-element simulation. The equilibrium drop shape, Gibbs free energy, and curvature-induced force along the cone of the equilibrium clamshell drops were obtained using a series of Surface Evolver (SE) simulations including the unique wetting behavior caused by the significant circumferential spreading near the apex of the cone. This series also incorporated the effect of drop volume, cone half-angle and contact angle. Furthermore, the effect of gravity was simulated based on the difference between sessile and pendant drops on the conical surface.}, journal={COLLOIDS AND SURFACES A-PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, publisher={Elsevier BV}, author={Sun, Xiaohang and Zhang, Wenwen and Lee, Hoon Joo and Michielsen, Stephen}, year={2019}, month={Jul}, pages={203–210} } @article{li_lee_michielsen_2017, title={Design of abrasion resistant super-antiwetting nylon surfaces}, volume={41}, ISSN={["1369-9261"]}, DOI={10.1039/c7nj02807e}, abstractNote={Abrasion resistant super-antiwetting nylon surface designed through a three-step wet chemistry steps}, number={22}, journal={NEW JOURNAL OF CHEMISTRY}, author={Li, Guoqing and Lee, Hoon Joo and Michielsen, Stephen}, year={2017}, month={Nov}, pages={13593–13599} } @article{lim_powell_lee_michielsen_2016, title={Integration of yarn compression in modeling structural geometry of liquid resistant-repellent fabric surfaces and its impact on liquid behavior}, volume={51}, ISSN={["1573-4803"]}, DOI={10.1007/s10853-016-0001-x}, number={15}, journal={JOURNAL OF MATERIALS SCIENCE}, publisher={Springer Nature}, author={Lim, Jihye and Powell, Nancy and Lee, Hoonjoo and Michielsen, Stephen}, year={2016}, month={Aug}, pages={7199–7210} } @article{park_suh_satam_lee_2014, title={Integration of Computer-Aided-Design and Smart Textiles to Prepare Multi-Functional Sportswear: Diet-Facilitating Suit}, volume={14}, ISSN={["1532-8813"]}, DOI={10.14504/ar.14.4.3}, number={4}, journal={American Association of Textile Chemists and Colorists Review}, publisher={American Association of Textile Chemists and Colorists (AATCC)}, author={Park, J.H. and Suh, M. and Satam, D. and Lee, H.J.}, year={2014}, pages={38–45} } @article{wang_michielsen_lee_2013, title={Symmetric and Asymmetric Capillary Bridges between a Rough Surface and a Parallel Surface}, volume={29}, ISSN={["1520-5827"]}, url={http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=ORCID&SrcApp=OrcidOrg&DestLinkType=FullRecord&DestApp=WOS_CPL&KeyUT=WOS:000326128900008&KeyUID=WOS:000326128900008}, DOI={10.1021/la401324f}, abstractNote={Although the formation of a capillary bridge between two parallel surfaces has been extensively studied, the majority of research has described only symmetric capillary bridges between two smooth surfaces. In this work, an instrument was built to form a capillary bridge by squeezing a liquid drop on one surface with another surface. An analytical solution that describes the shape of symmetric capillary bridges joining two smooth surfaces has been extended to bridges that are asymmetric about the midplane and to rough surfaces. The solution, given by elliptical integrals of the first and second kind, is consistent with a constant Laplace pressure over the entire surface and has been verified for water, Kaydol, and dodecane drops forming symmetric and asymmetric bridges between parallel smooth surfaces. This solution has been applied to asymmetric capillary bridges between a smooth surface and a rough fabric surface as well as symmetric bridges between two rough surfaces. These solutions have been experimentally verified, and good agreement has been found between predicted and experimental profiles for small drops where the effect of gravity is negligible. Finally, a protocol for determining the profile from the volume and height of the capillary bridge has been developed and experimentally verified.}, number={35}, journal={LANGMUIR}, author={Wang, Yongxin and Michielsen, Stephen and Lee, Hoon Joo}, year={2013}, month={Sep}, pages={11028–11037} } @article{lee_2012, title={Design and development of anti-icing textile surfaces}, volume={47}, ISSN={["0022-2461"]}, DOI={10.1007/s10853-012-6386-2}, number={13}, journal={JOURNAL OF MATERIALS SCIENCE}, author={Lee, Hoon Joo}, year={2012}, month={Jul}, pages={5114–5120} } @article{suh_lee_2012, title={Strategic use of CAD/CAM technology for apparel production}, volume={12}, number={1}, journal={AATCC Review}, author={Suh, M. and Lee, H.

As a drop moves along the cone, it must change shape to maintain a constant volume, and thus, it must change its surface energy. Simultaneously, the exposed surface area of the underlying cone must also change. The associated surface energies should balance each other, and the drop should stop moving when it reaches a location where the free energy is a minimum. In this paper, a minimum Gibbs free energy analysis has been performed to predict where a drop will stop on a conical fiber. To obtain the Gibbs free energies of a drop at different locations of a conical fiber, the theoretical expressions for the shape of a droplet on a conical fiber are derived by extending Carroll's equations for a drop on a cylindrical fiber. The predicted Gibbs free energy exhibits a minimum along the length of the cone. For a constant cone angle, as the contact angle between the liquid and the cone increases, the drop will move toward the apex of the cone. Likewise, for a constant contact angle, as the cone angle increases, the drop moves toward the apex. Experiments in which water and dodecane were placed on glass cones verify these dependencies. Thus, the final location of a drop on a conical fiber can be predicted on the basis of the geometry and surface energy of the cone, the surface tension and volume of the liquid, and the original location where the drop was deposited.}, number={19}, journal={LANGMUIR}, author={Michielsen, Stephen and Zhang, Jinlin and Du, Jinmei and Lee, Hoon Joo}, year={2011}, month={Oct}, pages={11867–11872} } @article{satam_liu_lee_2011, title={Intelligent design systems for apparel mass customization}, volume={102}, ISSN={["1754-2340"]}, DOI={10.1080/00405000.2010.482351}, abstractNote={To deal with the challenges of shortened product life cycle while considering various trends and consumers’ demands, several companies have begun to explore mass customization.

To define the purchasing patterns of the consumers, we analyze the statistical data of the world economy, consumer expenditures and online sales in the apparel sector. We also use statistical information about employment and labor cost in the textile industry to understand growing interest in mass customization. Based on our understanding of the advanced technologies developed for mass customization, we offer two potential ways to facilitate the design personalization in the entire process of apparel mass customization: two‐dimensional and three‐dimensional computer‐aided garment intelligent design systems. By developing a new CAD system that provides a versatile selection of styles and fits for apparel production processes, the efficiency of mass customization can be improved in the apparel industry.}, number={4}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Satam, Dnyanada and Liu, Yan and Lee, Hoon Joo}, year={2011}, pages={353–365} } @article{lee_willis_stone_2011, title={Modeling and preparation of a super-oleophobic non-woven fabric}, volume={46}, ISSN={["1573-4803"]}, DOI={10.1007/s10853-011-5314-1}, number={11}, journal={JOURNAL OF MATERIALS SCIENCE}, author={Lee, Hoon Joo and Willis, Colin R. and Stone, Corinne A.}, year={2011}, month={Jun}, pages={3907–3913} } @article{satam_lee_wilusz_2010, title={An approach to mass customization of military uniforms using superoleophobic nonwoven fabrics}, volume={10}, number={5}, journal={AATCC Review}, author={Satam, D. and Lee, H.

The experimental verification of the predicted shapes was performed using water, ethylene glycol, and Kaydol drops on nylon cylindrical fibers.

A plain woven fabric mimicking the Lotus leaf was created by further grafting 1H,1H-perfluorooctylamine or octadecylamine to poly(acrylic acid) chains which had previously been grafted onto a nylon 6,6 woven fabric surface. Water contact angles as high as 168 degrees were achieved. Good agreement between the predictions based on the original Cassie-Baxter model and experiments was obtained. The version of the Cassie-Baxter model in current use could not be applied to this problem since the surface area fractions in this form is valid only when the liquid is in contact with a flat, porous surface. The angle at which a water droplet rolls off the surface has also been used to define a superhydrophobic surface. It is shown that the roll-off angle is highly dependent on droplet size.
