    Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the nullrigidifyingnull nucleator compounds provide nucleation sites for polypropylene crystal growth. Upon slitting of the initial film and/or tube, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred nullrigidifyingnull compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2null-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such inventive tape fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

    Abstract: The specification discloses an improved automotive type carpet construction and method for manufacture thereof. The construction disclosed is particularly useful for lining the trunk of an automobile, the bed of an automotive type station wagon, or on the floor of a van type vehicle, where it is desired to have a construction which is light in weight, waterproof, easy to clean up, and yet can be made in a color to match the interior carpeting of the automobile. The construction disclosed has a primary layer of a ribbon fiber woven in a plain weave, with a continuous filament yarn inserted with a needled motion, and a bonding layer applied to the back thereof in a continuous hot melt flow. A non-skid layer may also be applied, if desired. The carpet construction is then die cut into one or more pieces with the piece(s) being sewn together or a binding being applied thereto.

    Abstract: A tufted pile fabric for use indoors or outdoors as a substantially permanent floor covering. The tufted pile fabric is made entirely from man-made or synthetic materials and includes a synthetic plastic primary backing, and a synthetic plastic secondary backing, laminated together by a hot melt adhesive to form a relatively rigid impervious sheet. The structure is then provided with a plurality of perforations through the substantially impervious sheet comprising the secondary backing, the hot melt adhesive and the primary backing to give the fabric a softer hand and breathability. The tufted pile fabric may then be adhesively secured to a floor structure by a water based adhesive, inert to the primary and secondary backings and hot melt adhesive, with the water evaporating through the perforations to set the adhesive and thereby avoid puckers and edge rippling due to unbonding the pile fabric from the floor structure.
