Abstract: A stationary working surface of a one roll microcreper member is of plastic resin having low wear and friction properties. As a primary pressing member subject to concentrated force it is 0.040 inch thick. One or both opposed retarder members of a bladed microcreper are of the plastic. Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed. By a load-spreading surface, the thermoplastic primary member is restrained without distortion. A primary member shown is sheet form, mounted between sheet metal members, one with a restraint surface. Sheet materials of polyolefins, wood pulp, etc.

By this surface being parallel to the roll axis the primary member is free for cross-machine thermal expansion.

Abstract: Wet wipe products are made from continuous wet wiping web material having thermoplastic fibers of type, concentration and dispersion capable of being heat-set to set the overall web material in a reformed shape. A succession of ridges and grooves is formed by passing the performed material through a dry creper apparatus in absence of adhesives, the action characterized by pressing the material with a stationary pressing surface to engage an advancing drive surface, the driven material bodily collapsing into a succession of adjacent ridges and grooves that increase the volume of the material. The wet wiping material is heat set in the ridge and groove configuration, enabling the ridge and groove configuration to be preserved when the wet wiping material is wetted and when squeezed and released. The self-restoring ridge and groove configuration provides stress concentrating edges and improves liquid delivery and wet wiping in a number of respects.

Abstract: A non-woven wet wipe product (22) comprising a sheet member, for use with a wet wiping agent (32), (18), the product comprising a segment of a non-woven self-supporting web (150) comprised of an assemblage of fibers including synthetic thermoplastic fibers and absorbent or adsorbent fibers, the non-woven web (150) being in a permanent, dry-creped, heat-set condition defining a succession of ridges (24) and grooves (26) in the overall body (30) of the web, the constituent thermoplastic fibers of the sheet member having been heat-set simultaneously during the imparting of the ridges and grooves to the web, the heat-set condition of the dry-creped thermoplastic fibers preserving the ridge and groove configuration during prolonged presence in the web of the wet agent (32). The wet wiping agent can be initially, prewet in the packaging, with liquid disposed through the body and on the surface of the dry-creped, heat-set sheet-form member and its constituent fibers.

Abstract: A laminated fabric material suitable for use in wiping human skin has two plies of fibrous material bonded together. Each ply of fibrous material is a nonwoven web of fibers having a fiber composition consisting of at least 50 wt. % thermally fusible plastic fibers to ensure efficient lamination. In particular, one of the plies consists of 100 wt. % thermally fusible plastic fibers. This enables the plies to be ultrasonically bonded together at sufficiently high bonding speeds. In addition, for the side or sides where an image, for example, a logo, is to be bonded into the fabric, the high percentage of thermoplastic fibers is reduced to ensure that the visibility of the image is not diminished due to swelling of the cellulosic fibers during saturation in aqueous solution. The surfaces of at least some of the thermally fusible plastic fibers of both plies are treated to render the plastic fibers hydrophilic, for example, by coating with surfactant.

Abstract: A novel open weave endless dryer belt is disclosed which comprises in a leno weave, warp yarns of synthetic organic fibers and crosswise yarns of synthetic organic fibers braided over a core of glass fibers and/or metal wire. The fabric weave is then finished with a coating of a temperature resistant resin. The fabric of the invention is useful for fabricating conveyor belts employed in conveying textiles through dryers and in like applications.
