Wool suit is very practical, warm and very good. Wool fabrics are generally classified as pure wool fabrics, that is, the wool content exceeds 90%. These fabrics are excellent in luster and feel, elastic and not easy to wrinkle. However, this kind of fabric also has some shortcomings, that is, it is easy to get insects, mold, pilling and storage, while the other is a fabric with a wool content of 70%. This kind of fabric generally belongs to wool blended fabric, which not only inherits the luster and feel of wool, but also inherits the excellent characteristics of polyester spandex and other chemical fiber fabrics. It will not change when it meets water, but it is still much worse than pure wool fabric in crease resistance, so the wool blended suit must be washed and ironed.
