The piece of knitted tubing also has a longitudinal axis with about 6 to about 9 stitches per inch, as typically measured along its longitudinal axis. Furthermore, the piece of knitted tubing is inverted upon itself at least once along its longitudinal axis to form a plurality of concentric layers of tubing, which are then substantially flattened to form the batt. Each of the layers has a similar length and substantially overlaps the other layers. The batt has a top surface, a bottom surface, and two open ends.

Abstract: A process for reconditioning a standardized tight head drum for re-use as either a tight-head drum or a wide-neck drum. The standardized tight head drum has an upper head drum welded to the drum body at a seam. This drum is reconditioned by separating the upper drum head from the drum along a cut line at a location below the seam. The cut edge is smoothed and sized and the interior of the drum is cleaned. For re-use as a tight head drum, an upper head having a fill plug and a vent plug is welded onto the cut edge of the drum. For re-use as a wide-neck drum, a neck ring is welded onto the cut edge and a wide-neck drum cover is placed on the neck ring. The reconditioned tight head and wide-neck drums have the same nominal volume and the same height and diameter dimensions as the tight head drum prior to reconditioning.

Abstract: A process for producing an apertured nonwoven fabric combines one or two outer nonwoven layer(s) with a layer of polymeric material having a lower melting temperature and a property of shrinking when melted. Heat and pressure are applied through a calender roll such that the polymeric material becomes bonded to the fibers of the nonwoven layer(s) and simultaneously shrinks and takes back the fibers away from the calendering points, thereby generating apertures through the nonwoven fabric. Preferably, the fibers are polyethylene or polypropylene fibers, and the layer of polymeric material is a thin plastic film of polyethylene stretch-wrap, elastomeric, or heat shrink material. One outer nonwoven layer may be combined with the plastic film layer to form a bi-laminate product, or two outer nonwoven layers may be combined with an intermediate plastic film to form a tri-laminate product. Low denier polypropylene/polyethylene bi-component fibers or a blend of higher and lower melting fibers may also be used.
