Yes, markers contain ink, which is the medium that transfers color from the marker to a surface. The ink composition depends on the type of marker. Permanent markers, such as those produced by Sharpie, contain solvent-based inks made of a dye or pigment in a liquid solvent, allowing them to adhere to a wide range of surfaces and resist water and fading. On the other hand, water-based markers, commonly used in schools and for art projects, use water as the solvent, making them easier to wash off from skin and most fabrics. Highlighters, another type of marker, often use a fluorescent water-based ink, designed to be translucent to allow text to be visible through the highlighting. There are also specialized markers, like dry erase markers, which use an erasable ink that doesn't adhere permanently to non-porous surfaces, allowing for easy removal.
Yarn pilling is when fibers in the yarn break, tangle, and form small balls on the fabric surface. Generally, yarns made from long-fiber materials such as silk, linen, and tightly spun wool are less likely to pill. Acrylics, polyesters, and other synthetic fibers, although durable, are prone to pilling due to their shorter fiber length. Wool blends can offer a balance between resistance to pilling and the warmth and comfort of wool. Look for high-quality, tightly spun yarns and consider the fiber type for projects you want to stay smooth over time.
Silicate absorbing resin is a specialized polymer designed to selectively remove silicate ions from solutions, mainly used in water treatment processes and aquarium maintenance. Silicates can promote diatom growth in aquariums, leading to unsightly brown algae. In industrial contexts, silicates in boiler and cooling water can form deposits, reducing efficiency and equipment life. These resins work through ion exchange, capturing silicate ions and replacing them with more innocuous ions like sodium. The resin's effectiveness depends on its ion exchange capacity and selectivity towards silicate over other ions. Regular regeneration with salt or acidic solutions is necessary to maintain its performance. Ideal for settings where controlling silicate levels is crucial for operational efficiency or aesthetic reasons.
