Some people think so, myself included. I have to wear a thin cotton shirt under my wool sweater.
causes the fiber , pieces of glass break off an embed themselves in your skin
No. Not particularly. It's itchy and kinda played out. It's almost 2012 get an electronic.
It is not true. Camel hair, mixed with wool, is often used to make sweaters and other clothing: coats, jackets, skirts, hosiery, etc.
It is often due to an itchy rash that may be caused by contact with skin of the wool. Many, including myself, find acrylic material to be far more comfortable and less irritating to the touch. For others, this causes no problem however.
It is heavy, it can put off an odor when wet and most people say when worn it is itchy. and plus it shrinks in the wash
There are two disadvantages to using wool. The first disadvantage is the material is itchy. The second is, it is a heavier material.
Dogs have super sensitive skin. Even more sensitive than humans, so allergies to wool are common. Give them synthetic fabrics or cotton, or flannel, they'll like it and not be itchy.
Wool socks are great for cold weather. Some types are itchy but kinds like merino or puregrow are not. They can ber very expensive but hold up very well for a long time if you treat them with care.
If by that do you mean is it biodegradable than the answer is yes. But, not all wool is created equal. Some sheep breeds have very fine,soft weak wool. While others have rough, strong wool. The stronger the wool the longer the product made with it will last. As a result sweaters are commonly made with soft weak fibers while rugs are made with the itchy more durable fibers. Heavy use will cause the wool product to break down over time as the fibers break apart.
Medieval people used a variety of animal fibers to make wool itchy, primarily from sheep. The itchiness often came from the natural properties of the wool fiber, particularly the coarse outer layer known as the cuticle. Additionally, the processing methods, such as carding and spinning, sometimes left the wool with rough edges, contributing to its prickly texture against the skin. To mitigate this, they sometimes blended wool with softer fibers or used different types of wool for specific garments.
Linen feels like quite smooth and a little rough round the edges.
