Abstract
The present invention provides a cleansing polyester fabric, which comprises (i) a polyester multifilament consisting of ultra yarns (monofilament) of 0.001 to 0.1 deniers or its false twist yarn as warp and (ii) a false twisted mixing yarn consisting of said polyester multifilament and a high shrinkage polyester multifilament with 10-50% of shrinkage rate in boiling water as a weft, and said fabric satisfies the following properties; sum of warp density and weft density: 220-320 yarns/inch, thickness of the fabric: less than 0.3 mm, and weight of the fabric: 70-180 g/m2. The cleansing fabric of the present invention is useful as a makeup cleansing fabric or as wiping fabric for fine products and optical devices since it exhibits excellent cleansing performance, is soft to the touch and does not damage the surface of products to be cleaned.
