  • Patent number: 4995928
    Abstract: A carrier strip or filament of cold drawable material is utilized to transport discrete lengths of elastic ribbon within a manufacturing apparatus. The elastic ribbons are extruded onto the carrier strip or around the filament and adhere thereto. The carrier strip and elastic ribbon are jointly stretched a predetermined amount. The stretched carrier strip and stretched elastic ribbon are bonded to a component of a final product, as, for example, the backing sheet of a disposable diaper, wherein the elastic ribbons are employed to elasticize the leg areas. The carrier strips greatly facilitate machine handling relatively short lengths of stretched elastic ribbons without waste. The carrier strips may be transversely guided along a predetermined path to follow the hourglass contour of the margins of a diaper having form fitting legs.

  • Patent number: 4968313
    Abstract: Disposable garments such as disposable diapers are disclosed that possess improved elastic characteristics. At least one garment outer sheet is composed of a drawable fabric, such as melt blown polymeric fibers or melt spun filaments. An elastic element is affixed in the relaxed condition to a web of outer sheet fabric. The elastic web is then stretched, and simultaneously the web in the area of elastic element attachment is drawn to impart a molecular orientation to the web fibers. As a result, the web fibers are permanently elongated. Upon relaxation of the stretched elastic element, shirrs or gathers are formed in the web fibers that permit subsequent stretching of the elastic element when the garment is worn. One of the outside sheet webs need not be drawable or drawn if it is performed with corrugations or pleats in the region of elastic element attachment. The present invention also includes apparatus for manufacturing the garment.

  • Patent number: 4910064
    Abstract: A non-woven web is provided that has conformability and drapability approaching that of woven fabrics. The non-woven web comprises a number of substantially parallel continuous filaments that are stabilized by melt blown fibers to create a coherent web. The continuous filaments are molecularly oriented, as by drawing before, during, or after deposition of the melt blown fibers. The melt blown fibers may be deposited on one or both sides of the continuous filaments, and two or more webs may be cross laid and laminated together. In one embodiment, the continuous filaments of a cross laid laminate are not bonded to each other. The continuous filaments are above to slide and slip relative to each other when the laminate is deformed, thereby decreasing stiffness and increasing drapability.

  • Patent number: 4276336
    Abstract: A thermoplastic non-woven net fabric and a method of making the same. The fabric includes a plurality of apertures with the apertures surrounded by axially drawn, biaxially drawn and undrawn areas. In one method, the web is perforated and then drawn by one or more pairs of helical rollers. The differential drawing of the perforated web greatly increases the tensile strength, area and drapability of the fabric. The apertures make the fabric suitable for use in garments, pillowcases, sheets, sterile wraps and is a breathable waterproof fabric for use in rain gear and tents. Two layers of the fabric can be used to form a pouch or carrier for conditioning agents such as a fabric softener for a laundry dryer, the softener agent being controllably released through the apertures.

  • Patent number: 4227952
    Abstract: Method and apparatus for making diapers with elastic bands in the leg-contacting zone of the diaper involves forming folds, tucks or festoons in the diaper backing sheet or facing sheet and applying elastic ribbon treated with adhesive over the web and across the gaps of the folds so that the ribbon does not adhere to the web portion in the folds. Hence the elastic ribbon is only adhered to the portions of the web between the folds. The elastic ribbons are cut in the gaps of the folds, with the material in the folds later forming the nonelasticized waistband portion of the diapers. At the ribbon-web assembly station, the facing or backing sheet is supported by spaced plates separated by gaps. Before the ribbon is applied, the folds are formed by tucker bars which successively interfit in the gaps between the support plates and push the web into the gaps.

  • Patent number: 4223063
    Abstract: A process for differentially drawing films and non-woven fiberous webs for increased drapability and strength of webs including at least in part cold drawable polymeric materials or blends thereof including incompatible polymer blends and polymeric matrixes having inorganic fillers draws portions of the web and leaves other portions undrawn. The process involves the subjecting of the web to two or more pairs of meshing toothed rollers to produce a fabric having a pattern of spaced apart undrawn quadrilateral shaped islands bounded fully on each of their four sides by an axially drawn area. Each undrawn island is continguous at each of its four apices to a biaxially drawn area. The preferred tooth form for the rollers is involute or cycloidal. The processed film or web is larger in area than the original, has a lower basis weight, and has greatly enhanced strength, softness, bulk, texture and drapability.

  • Patent number: 4013816
    Abstract: This invention relates to a stretchable spun-bonded web suitable as top-liner for a disposable diaper, pad, bandage and the like, and a process for making the same. In particular, the invention relates to a polyolefin web where the crossover points of the fibers do not rupture when the web is stretched to 50% of its original length, but maintains approximately its original structure, which makes it extremely suitable for such applications. The web is made by melt blowing polypropylene of less than 1.2 intrinsic viscosity at a filament velocity of at least 15 meters per second on a smooth collecting surface having a temperature less than 65.degree. F.

  • Patent number: 3949130
    Abstract: A spun bonded web of substantially continuous synthetic filaments has one side that is at least two times smoother than the other side. The majority of the filament cross points within the web are fuse bonded during the web spinning process. The web is spun by blowing a line of spaced, molten synthetic filaments onto a smooth collecting surface which is in motion substantially transverse to the direction of flow of the filaments. The filaments are still soft when they contact the collecting surface and flatten against the collecting surface to form the smooth side of the web. On the other side of the web, the filaments are randomly entangled to form the rough side of the web. A disposable diaper or like article is formed by covering at least one side of an absorbent pad with the fabric of this invention, the rough side of the fabric facing the absorbent pad and serving to anchor the pad against bunching, splitting, or separating.
