Yarn comes from many different materials, and choosing the right one for knitted sweaters is crucial for functionality. Not all knitting yarn is good for sweaters, as the materials used will offer you different comfort levels as well as wear; you should thus do proper research on the best ones to use for sweaters. A few of the different yarn materials for knitted sweaters is discussed here.
When considering knitted sweaters for warmth, yarn material that is made of wool is the best to go for. Wool is very warm and can keep you warm even in the cooler seasons. One drawback thong is that wool tends to shrink, thus proper care will be required to minimize the shrinkage.
Cashmere yarn is the most durable yarn material for making knitted sweaters. It is just as insulating as the wool material, but lasts much longer. It is also comfortable and much softer than wool. Just like wool, it is prone to shrinkage, thus proper care is needed to minimize or avoid shrinkage. Choose cashmere yarn material if durability is your primary concern with knitted sweaters.
Cotton is a very good fabric to use when making sweaters for wear during the summer and spring weather. It is not as warm as the other two, and thus not good to wear if warmth is your primary concern. The material is also soft and easy to wash, with less shrinkage experienced as compared to the other two yarn materials.
