Mercerized wool is a kind of wool yarn, which is a process in which wool is dyed by textiles after mercerization. After chlorination treatment, the protein on the wool surface is softened, which makes the wool yarn soft and shiny. In foreign countries, most wool is steamed with hot steam, stretched and shaped, and the general process is similar.

Light wool is generally woven into pure wool or blended with other materials. Mercerized wool is generally used as clothing fabric. Pure wool or woolen sweaters with high wool content can be used as close-fitting base, while fabrics with low wool content can be made into different clothes according to the characteristics of blended fabrics.

Mercerized wool is a brand-new wool spinning process with the development of industrial technology in the 1990s. To put it bluntly, it is a dyeing process. The main feature of this process is chlorination of the cut wool, which greatly improves the handle and color of the yarn.

Ordinary wool fabrics may be easy to pilling or shrink after wearing for a period of time, while mercerized wool is smoother, which can reduce friction, is not easy to pilling and has a glossy surface. And because wool scales are peeled off after special treatment, they are not easy to shrink.
