  • Publication number: 20230121817
    Abstract: Covers comprising a nonwoven fabric including a plurality of recycled polyester fibers, such as a plurality of staple fibers, is provided. The plurality of recycled polyester fibers may be formed from a post-consumer polyester, a post-industrial waste polyester, or a combination thereof. The covers provide desirable vapor transmission while also providing an improved hydrostatic head. The covers may be provided in a variety of configurations. Methods of forming such covers are also provided.

  • Patent number: 11219170
    Abstract: Shelters for enhancing the growth of trees by protecting tree trunks from damaging sunlight. The shelters include a longitudinal tubular structure having a top edge and a bottom edge. The shelters includes a conduit extending from the top edge to the bottom edge of the shelter. The longitudinal tubular structure may be formed from a polymeric material including a pigment selected to block at least a portion of electromagnetic radiation. The polymeric material including the pigment blocks at least about 30% of electromagnetic radiation at any wavelength from about 200 nm to about 2500 nm.

  • Patent number: 9951243
    Abstract: Disclosed are aqueous carpet-coating compositions suitable for use as binders or adhesives in carpet products. Such compositions, prior to being applied to carpet substrates and cured, comprise: A) a selected type of vinyl acetate/ethylene (VAE) copolymer dispersion which has been stabilized with emulsifiers and a cellulose ether-based protective colloid, and B) at least one carbon black based filler in the form of a dispersion/slurry with a solids content between 20 and 70%. These coating compositions exhibit especially desirable initial viscosity and viscosity stability characteristics. Carpet products which utilize such coating compositions to provide binder and/or adhesive layer within the carpet are also disclosed. Such carpet products can have desirable odor-controlling and odor-absorbing properties.

  • Patent number: 9624622
    Abstract: Disclosed are carpet products comprising at least one flexible substrate and at least one coating and/or adhesive layer associated with the at least one flexible substrate. The coating and/or adhesive layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a selected ethylene content or glass transition temperature. It is also preferably substantially free of cross-linkable co-monomer moieties which generate formaldehyde upon curing and preferably has a particle size, dw, ranging from about 50 to about 500 nm. The carpet product is substantially free of polyvinyl chloride and bitumen and exhibits a Class B1 flame-retardancy in accordance with DIN 4102-14, corresponding to a critical heat flux of ?about 4.5 kW/m2.

  • Publication number: 20170099786
    Abstract: Shelters for protecting and enhancing the growth of plants reinforced by receiving a retaining structure are provided. The shelters include an outer longitudinal tubular structure having a first-outer-longitudinal-tubular-structure end and a second-outer-longitudinal-tubular-structure end diametrically opposed to the first-outer-longitudinal-tubular-structure end; an inner longitudinal tubular structure positioned within the outer longitudinal tubular structure and having an inner wall, a first-inner-longitudinal-tubular-structure end, and a second-inner-longitudinal-tubular-structure end diametrically opposed to the first-inner-longitudinal-tubular-structure end; and a segmented annular portion positioned between the outer wall and the inner wall. The segmented annular portion may comprise a plurality of segmented annular divider walls defining a plurality of through channels extending from the first-outer-longitudinal-tubular-structure end to the second-outer-longitudinal-tubular-structure end.
