Washable yarn refers to yarn that has been treated or manufactured in a way that allows it to be machine washed without damage, significant shrinking, or felting, which often happens with traditional wool yarns. This is achieved through processes like superwash treatment, where wool fibers are coated or their scales are smoothed to prevent interlocking and felting when washed. There are also synthetic and cotton yarns naturally resistant to the issues associated with washing, making them an excellent choice for items that require frequent cleaning. Washable yarns are particularly popular for baby clothing, blankets, and items that are used daily as they combine the warmth and comfort of knit or crocheted items with the practicality of easy cleaning.
Comparing the strength of polyurethane and epoxy depends on the specific application and the forms of these materials. Epoxy is generally more rigid, making it excellent for applications requiring strong adhesion and high structural strength. It has a superior bond strength on a variety of surfaces, including concrete and metal, and is better at resisting chemical corrosion. On the other hand, polyurethane is more flexible, which makes it more resistant to impact and abrasion. This flexibility allows polyurethane to absorb impacts without cracking, making it ideal for surfaces that undergo significant movement or expansion. Additionally, polyurethanes are often preferred for their durability in harsh weather conditions, as well as for their resistance to UV light, which can degrade epoxy over time. Thus, while epoxy may offer superior tensile strength and bonding capabilities, polyurethane provides better performance in applications that require flexibility, impact resistance, and environmental durability.
Yes, the corn kernels you see in your poop contain cellulose. Corn has a tough outer shell made of cellulose, a type of fiber that the human digestive system cannot break down. This is why corn kernels may appear nearly intact in stool after consumption. Our bodies lack the enzyme (cellulase) needed to break down cellulose, which is why these fibers pass through our digestive system largely unaffected. While the body can digest the inside of the corn kernel, which is starchy and breaks down easily in the stomach and small intestine, the outer cellulose shell often remains whole, making it visible in feces. This phenomenon isn't unique to corn and happens with other foods high in cellulose and certain fibers.
