Aerogels are ultra-lightweight, highly porous materials with excellent thermal insulation properties. However, their brittle nature makes direct integration into textiles challenging. So then, how can we convert them to more usable form? Let's dive in.
Electro-osmosis in textile membranes is a fascinating process where an electric field drives the movement of fluids through a textile material. But what exactly are textile membranes? These are porous materials made up of fibers or a matrix that allows fluids to pass through, and they’re widely used in applications like filtration and separation processes due to their ability to selectively move liquids.
Understanding the effects of test setups and material testing parameters on arc flash results is vital for ensuring the safety of workers exposed to electrical hazards. The variability in heat transfer processes during arc flash events can significantly influence the arc ratings of personal protective equipment (PPE). This blog explores how different testing conditions impact arc flash results and discusses their implications for end users in various industrial settings.
OmniFiber developed at MIT, is like a super flexible string that can move and feel things. It's not just any string though; it's a high-tech string made of tiny tubes filled with fluid that can change its shape and sense what's happening to it. This technology opens up a world of possibilities for how we interact with things around us.
Sweat wicking is an important phenomenon for a sports wear fabric. Sweat wicking facilitates following functionality in a sports wear.
Standardizing woven fabrics, for comparison, can be done, by using parameters like fabric degree of tightness. This facilitates the creation of similar fabrics with variable construction parameters while predicting beat-up resistance in weaving. Standard fabrics offer advantages like design flexibility, predicting fabric properties, and aiding in specific end-use constructions, ultimately impacting weaving efficiency and fabric quality.
When we hear the word melt-blown, immediately we visualize a thin non woven used in a mask. Many of us are also aware that it is primarily made from Polypropylene (PP).It is normally supported by one or more spun-bond or melt-blown layer, but in general it is not stretchable and fragile to handle.
Plastic pollution is a global crisis that is wreaking havoc on our coasts and oceans. Among the many culprits contributing to this environmental catastrophe are plastic objects made from polyethylene terephthalate, or PET. These objects, once discarded, can linger in the environment for hundreds of years, causing harm to marine life and ecosystems. However, a recent scientific breakthrough offers a glimmer of hope in the fight against plastic pollution.
Ablative composites are specialized composite materials composed of high melting point fibers and polymeric resins that yield char at high temperatures. These composites are used in extreme environments, such as reentry vehicles like Gaganyaan, where they experience harsh conditions including high heat, pressure, and particle impact. These composites are made with reinforcements like carbon, graphite, silica, and glass, along with resins like phenolics and furfuryl alcohol.
Electrospinning is a technique used to produce nanofibers from polymer solutions or melts. The process involves creating an electric field between a liquid polymer source and a grounded collector, which results in the stretching and solidification of the polymer into ultrafine fibers as the solvent evaporates.
