MOLDABLE NONWOVEN COMPOSITE
A moldable nonwoven composite contains a nonwoven face layer, an adhesive layer, a sound absorbing nonwoven layer, and a backing layer. The upper surface of the nonwoven face layer forms the first side of the moldable nonwoven composite. The nonwoven face layer contains between about 80 and 95% wt first polyester terephthalate fibers and between about 5 and 20% wt first low melt polyester fibers. The adhesive layer contains a first low melt polyester adhesive. The sound absorbing nonwoven layer contains between about 40-90% wt second polyester terephthalate fibers and between about 10 and 60% wt second low melt polyester fibers. The lower surface of the polymer backing layer forms the second side of the moldable nonwoven composite. The polymer backing layer contains a second low melt polyester adhesive. The entire moldable nonwoven composite essentially consists of polyester, defined as being as least 95% wt polyester.
Molded ceiling material for vehicle and production method therefor
A ceiling material body (1a) includes a substrate layer (2) formed from rigid urethane foam; a first fiber-reinforced layer (3) provided on an in-cabin side of the substrate layer (2); a second fiber-reinforced layer (4) provided on an out-cabin side of the substrate layer (2); a surface layer (5) provided on an in-cabin side of the first fiber-reinforced layer (3); and a back layer (6) provided on an out-cabin side of the second fiber-reinforced layer (4). The second fiber-reinforced layer (4) includes a glass paper (7) overlaying the substrate layer (2) and a glass mat (8) overlaying an opposite side of the glass paper (7) from the substrate layer (2).
Depth filter
A depth filter with excellent filtration accuracy and pressure resistance performance even for fluids containing high density and high viscosity powder fine particles. A depth filter having a base material layer, a filtration layer, and a skin layer, in that order, wherein: the substrate layer and the skin layer are layers made by a nonwoven fabric being wound and thermally fused; the filtration layer is a laminate in which at least a nonwoven fabric and a net are laminated, being wound twice or more; and the nonwoven fabric contained in the filtration layer contains a mixed-fiber nonwoven fabric containing two or more types of fibers with mutually different average fiber diameters.
Installation and method for producing a single- or multi-layer nonwoven
An installation and a method for selectively producing a single-ply or alternatively a multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction.
Antibacterial and antiviral degradable mask and manufacturing method thereof
An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.
THERMOPLASTIC-IMPREGNATED CELLULOSIC NONWOVEN AS A COMPOSTABLE FILTER MATERIAL FOR LIQUIDS
The present invention relates to a heat sealable filter material for liquids that is fully compostable. The filter material is a thermoplastic-impregnated cellulosic nonwoven having a Textest Air Permeability of 50 to 1000 L/m.sup.2.Math.s. The filter material can be laminated to a support layer without the additional use of an adhesive. Further aspects of the present invention include compostable packaging elements comprising the compostable filter material described herein.
WEB FOR DOWN PADDING, AND ULTRA-LIGHT DOWN PADDING WITH 4-WAY HIGH ELASTICITY AND HIGH INSULATION INCLUDING THE SAME
The present invention is an invention about ultra-light down padding and a web for down padding used in its manufacture, and relates to ultra-light down padding having a thin thickness, excellent insulation and excellent elasticity in 4-way (or multi-directions), and a web for down padding used for manufacturing the same.
BARRIER ARTICLE FOR A RECHARGEABLE ELECTRICAL ENERGY STORAGE SYSTEM
A barrier article comprises a multilayer article that includes a plurality of core layers and a plurality of binder layers, wherein at least one core layer includes a woven or nonwoven fiber mat or fabric, and wherein at least one binder layer includes a silicone material.
