  • Patent number: 8921242
    Abstract: A light weight, durable, easily recyclable pool cover includes a fabric covering with reinforcing and attachment straps wherein, the reinforcing and attachment straps are attached to said fabric in a criss-crossed pattern. The fabric covering and the straps are produced from a single polymer consisting of polypropylene. The pool cover is entirely recyclable at end of service life by chopping the pool cover components in a simple machine producing granules useful for injection molding of polypropylene products. The pool cover fabric is produced by subjecting three layers of polypropylene sheet material to heat and pressure forming a strong durable fabric wherein the top layer and bottom layer are a solid fabric and the middle layer is multi-filament mesh of polypropylene threads.

  • Patent number: 8907155
    Abstract: A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water-barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable.

  • Patent number: 8679992
    Abstract: An elastic composite formed from a laminate that contains an elastic film and a lightweight nonwoven facing having a low strength in the cross-machine direction (“CD”) is provided. Due to the low strength of the facing, it is desirable that the elastic film have a sufficient thickness and weight to enhance the strength of the resulting composite. Unfortunately, the ability to join an elastic film to such a lightweight nonwoven facing becomes increasingly difficult as the thickness of the film increases. In this regard, the present inventors have discovered that a second laminate may be employed in the elastic composite that is formed from a thermoplastic film and nonwoven facing to impart increased strength to the composite. The film and facing of the second laminate may be formed from the same or different materials than the film and facing of the first laminate. Regardless, the laminates are positioned so that the elastic and thermoplastic films are in a face-to-face relationship.

The use of a terephthalic acid monomer results in a polymer chain containing 1,4-(para-) terephthalate units linked in a generally linear configuration (e.g., ˜180°). The blend also contains a second aliphatic-aromatic copolyester formed from a phthalic acid and/or isophthalic acid monomer. The use of such a monomer results in a polymer chain containing 1,2-(ortho-) and/or 1,3-(meta-) linked units. The inclusion of 1,2-(ortho-) and/or 1,3-(meta-) linked units into the polymer backbone of the second copolyester introduces an angle or “kink” (e.g., ˜120° kink for a 1,3-linkage) into the otherwise linear polymer chain. The “kinks” in the second copolyester backbone reduce its melting point and degree of crystallinity, which have an influence on its physical properties (e.g.

  • Publication number: 20120178333
    Abstract: A low viscosity, high tensile strength polymer having a bi-modal molecular weight distribution is produced using a combination of high molecular weight polymer and low molecular weight polymer. The polymer chains have a high content of meso dyads that results in a greater amount of crystalline regions when the polymer is solidified. The low molecular weight chains provide high flow characteristics when the polymer is molten. The process for producing the high content of meso dyads includes the use of an external donor catalyst during the reaction.

  • Publication number: 20120172214
    Abstract: A sheet material that includes an elastic component or material (e.g., film, nonwoven web laminated to the elastic component, etc.) is provided. The elastic component is formed from a styrenic block copolymer composition containing from about 10 wt. % to about 90 wt. % of styrene-butadiene-styrene block copolymer; and from about 10 wt % to about 90 wt. % of styrene-isoprene/butadiene-styrene block copolymer. The styrenic block copolymer composition has good viscosity stability during extrusion and thus may be readily formed into an elastic sheet material. The elastic sheet material may be subsequently crosslinked to achieve the desired elastic and mechanical properties.

    Abstract: The invention relates to a method for producing nonwoven/film laminates for personal hygiene articles, from an initial film web consisting of a thermoplastic polymer and an initial nonwoven web. According to said method, the initial film web and the initial nonwoven web, whose melting point lies above the crystallite melting point of the polymer, are heated to a temperature that exceeds the crystallite melting point of the polymer and lies below the melting point of the initial nonwoven web. The laminate is then guided through a cooled nip and is cooled to a temperature that lies below the crystallite melting point of the initial film web. The invention also relates to laminates that can be produced by said method.
