Abstract: A color-fast and high-crocking combination fabric and methods for making the same. The color-fast and high-crocking fabric consists of dyed natural fibers and dyed polyester fibers. The natural and polyester fibers are dyed and/or colored before being combined into yarns and fabrics. The color-fast and high-crocking combination fabric has very high color-fastness as measured by crocking standard, while maintaining a quality hand feel. The color fastness can withstand at least thirty regular cold-temperature home-wash laundries.

Abstract: A blended yarn comprises a plurality of first fibers and a plurality of second fibers. A coefficient of friction of the second fibers is greater than a coefficient of friction of the first fibers. Abrasion resistance characteristics of the second fibers are greater than abrasion resistance properties of the first fibers. A gripping ability of the second fibers is greater than a gripping ability of the first fibers. The plurality of second fibers are combined with the plurality of first fibers such that the first fibers extend along the length of the blended yarn and the second fibers do not extend along the length of the blended yarn at least a portion of the second fibers are engaged with and extend from the plurality of first fibers effectively to define surface characteristics of the blended yarn.

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.

Abstract: A yarn feeding device including a preheater 23 for preheating a yarn bar Y, a first feed roller 27 for drawing the yarn bar Y from an original yarn package 11 is provided opposite to a temporary twisting and relaxation heat treating device including a second feed roller having a higher circumferential speed than that of the first feed roller 27, a temporary twisting tool 31 for twisting the yarn bar Y and a second heater 35 for carrying out a relaxation heat treatment on the temporary twisted yarn bar Y with a worker passage A interposed therebetween, a first heater 41 and a cooling plate which thermally fix a twist retroacting along the yarn bar Y are provided in portions positioned above from the yarn feeding device to the temporary twisting and relaxation heat treating device, and a winding device 51 including an automatic switching device is provided on an opposite worker passage A side of the temporary twisting and relaxation heat treating device.
