摘要： A fiber blend containing: (a) a cellulose acetate (CA) staple fibers having a denier per filament (DPF) of 3.0 or less; and (b) structural staple fibers having a dpf of 6.0 or more; and (c) optionally binder fibers. The fiber blend can be made into nonwoven webs for heat-bonding and subsequent use as thermal insulation in, e.g., outerwear, bedding, etc. The fiber blend can now contain sustainably derived fibers, optionally biodegradable, that provide good thermal insulation clo values and loft even after multiple wash cycles along with good short term compression recovery.

摘要： Embodiments of the present invention replace at least some of the flame resistant fibers traditionally used in the batting of a thermal liner (e.g., aramids) with thermally stable polyamide fibers (e.g., nylon fibers). The TPP performance of garments incorporating embodiments of thermal liners contemplated herein is comparable to—if not improved over—garments formed with traditional thermal liners.

摘要： A non-woven fabric is provided which includes a three-dimensional array of fibers. The three-dimensional array of fibers includes an array of standing fibers extending perpendicular to a plane of the non-woven fabric and attached to a base substrate, where the base substrate is one or more of an expendable film substrate, a metal base substrate, or a mandrel substrate. Further, the three-dimensional array of fibers includes multiple layers of non-woven parallel fibers running parallel to the plane of the non-woven fiber in between the array of standing fibers in a defined pattern of fiber layer orientations. In implementation, the array of standing fibers are grown to extend from the base substrate using laser-assisted chemical vapor deposition (LCVD).

摘要： Contrary to packagings or bottles made of pure materials like PET, nonwovens usually consist of a mix of materials and are as such difficult to include in a recycling process. The present invention relates to a method for recycling polyester-based nonwovens comprising 5 to 50% of PET/coPET low melt staple fibers into polyester staple fibers (PSF), and further including these fibers into new nonwovens for a large variety of articles for applications in virtually any technical field.

摘要： A thermal insulation batt is created from recycled carpet fibers and fire resistant cotton shoddy bonded by staples of bi-component fiber having a polyester core and low melting polymeric sheath. The low melting polymeric sheath melts at a temperature well below the melting or degradation temperature of any of the carpet fibers from the recycled carpets. Since the sheath has a small thickness, the amount of melt created is small and bonding occurs only between the bi-component staple fiber and adjacent carpet fiber or fire resistant cotton shoddy without melt overflow. The rigidized thermal insulation batt can be used in a building between studs and may be used in an automobile door for sound proofing. This product is particularly well suited for use as acoustic and thermal insulation in buildings as “non-load bearing” partitions in interior offices of commercial buildings. This bonded low density composite fibrous structure has fire retarding constituents incorporated within the batt to retard propagation of building fire. These stated uses are non-limiting; and other uses are contemplated, including automobile interior structures.
