Abstract: A process for abrading fabrics to produce a sueded hand is provided. In particular, the process is directed to the sueding of cotton containing fabrics both before and after mercerization, to produce a unique combination of hand and retained fabric strength. Fabrics treated by this process are also contemplated within the scope of this invention.

Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.

Abstract: A top bedsheet, bottom (fitted contour) bedsheet, or pillow case is produced by circularly knitting, in a jersey knit configuration, a sheath and core yarn into a fabric. The sheath fibers comprise short staple fibers such as cotton or comparable cellulosic fibers, and provide at least 50 percent of the yarn and preferably about 68-83 percent of the yarn. The core fibers are long staple synthetic fibers such as polyester, and are completely covered by the cotton so that the product has smoothness of hand. The fabric has a weight of approximately four ounces per square yard, and is finished so that it has a relaxed shrinkage of about five percent in both the length and width dimensions. The sheath and core yarn configuration is produced by passing a sliver of sheath fibers and a roving of core fibers through a trumpet, and then through the rear rolls, apron, and front rolls of a drafting apparatus to produce a drafted composite sliver, and then mechanically imparting a twist to the drafted composite sliver.

After weaving, the yarn stabilization is reversed by a desizing operation. The fabric is subsequently heat treated to develop crepe characteristics.

Abstract: Spun yarns are subjected to the vortex action of an impinging, circularly rotating fluid to lay down extending staple fibers against the yarn body while causing the yarn path to balloon and are then contacted with a melt size presented on a slower moving grooved melt size applicator. As a result of the ballooned yarn path, the yarn wipes melt size from the sides and bottom of the groove, giving the yarn a smooth, substantially continuous coating on its outside surface. Spun yarns so treated may be successfully woven as filling yarn on a water jet loom and knit as the warp yarn or as laid-in yarns on a knitting machine without excessive lint accumulation.
