Abstract: An introduction of hydrophilic and easy-dyeable Yi MianTM fibers and fabrics are given in this paper including their physical properties and characteristics of the dyeing and finishing process. Yi MianTM fibers can be dyed using dispersed dyes under normal pressure, and YI Mian/Cotton blends can be dyed in one-bath one-step process, which could effectively save energy. Also, they have appropriate tensile strength, desirable handle and high hydrophilicity that are similar to cotton. Yi MianTM fabrics have better absorption and quick-drying properties than conventional polyester and cotton fabrics, and can be used to produce a variety of casual fabrics and sports fabrics.

Key words: cottony polyester, boiling dyeing under normal pressure, one-bath one-step dyeing, moisture absorption and fast drying
