A bio-inspired, leaf-like pumping strategy by mimicking the transpiration process through leaves is developed for autonomous and continuous liquid transport enabled by durable hydrophilic sponges. Without any external power sources, flows are continuously generated ascribed to the combination of capillary wicking and evaporation of water. To validate this method, durable hydrophilic polydimethy...

Abstract Yarn wickability achieves high thermo-physiological comfort. Therefore, this paper aimed to investigate yarn and analyze statistically factors affecting wicking performance. Methodology consists of testing height for ring spun produced from three levels fibre types twist at two doubling. Statistical tools such as ANOVA, T-test Post-hoc tests analyzed the impacts on heights. Findings sh...

In this study, the effects of using detergent with boron and softener on repetitive washing towel loincloths were investigated. For aim, two types as light heavy weight loincloth one side piled non-piled washed at 10 20 cycles by only ecofriendly both softener. Then, density changes, liquid wicking transfer properties, tear strength whiteness index values fabric samples determined after cycles....

Dense arrays of aligned carbon nanotubes are designed into strips, nanowicks, as a miniature wicking element for liquid delivery and potential microfluidic chemical analysis devices. Liquid wicks away along the nanowicks spontaneously. This delivery function of nanowicks enables novel fluid transport devices to run without any power input, moving parts or external pump. Flow around the opaque n...

Evaporation of ethanol from square packed arrays of 3.95 mm diameter copper spheres in a transparent, enclosed chamber is investigated. The enclosure ensures that relatively saturated vapor conditions exist near the free surface. The desired heat flux is imposed on the copper substrate upon which the copper spheres are mounted, and the liquid level in the bed is maintained by wicking from a con...

Boiling heat transfer is dictated by interfacial phenomena at the three-phase contact line where vapor bubbles form on surface. Structured surfaces have shown significant enhancement in critical flux (CHF) during pool boiling tailoring phenomena. This CHF has been primarily explained two structural effects: roughness, which extends length bubble base, and wickability, ability to imbibe liquid t...

Textile industry is constantly searching for easy and rapid ways to improve the properties of textiles. In this matter, plasma treatments have already proven be an efficient green solution, as they proceed in a dry environment require minimal use chemicals. To date, most work on subject has been performed with low-pressure plasmas. Recently, atmospheric plasmas received increasing interest, esp...
