Snowman Face Christmas Shirt

Because of its extremely low micron count, Merino wool is a super fabric. Based on how reactive your skin is, anything higher than 20 microns may cause you to experience itching and irritation. For comparison, ordinary wool is approximately 30 microns in thickness. The thickness of high-quality merino wool is approximately 15 microns. Another issue is how wool is processe (carded, spun, winding yielding yarn size) most wools are not washed during processing and have high lanolin content before they are dyed. Lanolin is a complex combination of waxes, oils, esters and alcohols that coat the Snowman Face Christmas Shirt moreover I love this fibers of sheep’s wool. So goats would not have “lanolin.” But all mammals probably have some similar substance that coats their hair fibers. We just don’t call it lanolin. As for allergies to wool and lanolin, there has long been a debate about both. The scientific consensus seems to be fairly well resolved about wool. The scratchy feeling that people get when wearing wool is not a true allergic reaction, which would involve activation of the immune system. People report any fabric as being scratchy and irritating when it has over 5% of its fibers thicker than 30 microns in diameter. Many sheep’s wools have fibers in this range. But scientists have duplicated the sensation with artificial fibers such as nylon, proving that the skin irritation is not specific to wool. Probably some people have more sensitive skin, or have less of their own hair that holds the fabric away from the skin, or any number of other reasons that make them more “allergic” to wool than other people. But it seems fairly clear that this is a physical irritation of the skin, not an allergy.
