Abstract
A strong, highly absorbent hard finished nonwoven toweling fabric consisting of wood pulp and textile fibers free from added binders is prepared by forming a wet-laid web of a blend of fibers containing 50 to 75 weight percent wood pulp and 25 to 50 weight percent staple length synthetic fibers and subjecting the fibers in the wet-laid web to hydroentanglement. The fabric may be apertured or essentially nonapertured and may be made water repellant. The fabric may be used in medical and surgical application, household cloths, food service wipes, industrial machinery wipes and the like.
Claims12
A method of making a highly absorbent nonwoven fabric consisting essentially of wood pulp and staple length synthetic fibers which comprises forming a wet-laid web containing 50 to 75 weight percent wood pulp basis the dry weight of the fibers and 25 to 50 weight percent synthetic fibers having a fiber length in the range of from about one-quarter inch to about one inch, forming a compacted highly absorbent web of entangled fibers by subjecting the fibers in the wet-laid web to hydroentanglement, and drying said web to form said nonwoven fabric.
A method of making a highly absorbent nonwoven fabric consisting essentially of wood pulp and staple synthetic textile fibers free from added binders which comprises laminating a plurality of wet-laid webs each containing 50 to 75 weight percent wood pulp basis the dry weight of the fibers and 25 to 50 weight percent synthetic fibers having a fiber length in the range of one-quarter inch to one inch, combining said webs into a single compacted highly absorbent web of entangled wood pulp fibers and synthetic fibers by subjecting the laminated webs to hydroentanglement, and drying the hydroentangled web to form a highly absorbent fabric.
A highly absorbent nonwoven fabric having a basis weight in the range of three ounces to about eight ounces per square yard free from added binders and consisting essentially of 50 to 75 weight percent wood pulp basis the dry weight of the fibers and 25 to 50 weight percent synthetic fibers having a fiber length in the range of one-quarter inch to one inch uniformly admixed with one another in a wet-laid web and hydroentangled under sufficient energy to form a compact, highly absorbent fabric.
