NONWOVEN FABRIC AND ASSOCIATED COMPOSITE AND METHODS OF MAKING
A nonwoven fabric useful for forming composite panels includes specific amounts of reinforcing fibers, a polyimide, and a block polyestercarbonate-polysiloxane. The nonwoven fabric has a density of 0.03 to 0.2 gram/centimeter.sup.3, an areal density of 100 to 400 gram/meter.sup.2, and a tensile modulus of 50 to 1000 megapascals. Also described are a method of forming the nonwoven fabric, a composite formed from the nonwoven fabric, and a method of forming the composite.
HIGH TEMPERATURE TREATED MEDIA
A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.
Non-woven fabric and filter using same
A non-woven fabric body (11) that forms a non-woven fabric (1) is formed by integrating composite polyester fibers (2) and flame-retardant acrylic fibers (3) which serve as the other fibers of the rest. The composite polyester fibers (2) have a core-sheath structure in which a sheath portion (4) is formed of a low melting point polyester and a core portion (5) is formed of a high melting point polyester having a higher melting point than that of the low melting point polyester. The composite polyester fibers (2) are contained in an amount of 15% to 80% by weight in a total of 100% by weight of the non-woven fabric body (11). Further, an apparent density of the non-woven fabric body (11) ((a basis weight of the non-woven fabric body)/(a thickness of the non-woven fabric body)) is 0.005 g/cm.sup.3 to 0.040 g/cm.sup.3. In addition, a bending resistance of the non-woven fabric body (11) in a flow direction of the fibers is 50 mN.Math.cm to 220 mN.Math.cm, and a bending resistance in a width direction that is orthogonal to the flow direction is 20 mN.Math.cm to 140 mN.Math.cm.
Needle punched carpet
A needle punched carpet for use in a car is disclosed. The needle punched carpet comprises at least a needle punched facing layer defining a top layer and made of staple fibers. The staple fibers comprise hollow fibers having a hollow fiber content that is at least more than 45 weight % of the total staple fibers.
SOUND-ABSORBING THERMAL-INSULATING MATERIAL
A sound-absorbing thermal-insulating material (1) includes flame resistant organic fibers (2) and inorganic fibers (4) bonded to the flame resistant organic fibers (2). The flame resistant organic fibers (2) shrink and the inorganic fibers (4) are distorted, so that the flame resistant organic fibers (2) and the inorganic fibers (4) are entangled with one another and distend.
WET SHEET FOR CLEANING AND METHOD FOR PRODUCING WET SHEET FOR CLEANING
A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet for cleaning includes outer layers which are made of hydrophobic fiber and which are each arranged on a front surface and a back surface, and an inner layer which is made of hydrophilic fiber and which is arranged between the outer layers. The inner layer is provided with a hydrophilic fiber inner layer with the hydrophilic fiber and a hydrophobic fiber inner layer with hydrophobic fiber. The hydrophobic fiber inner layer is adjacent to at least one of the outer layers. The inner layer includes pulp by 50 wt % or more, has a grammage of 20 to 75 g/m.sup.2, and occupies 20 to 70% of a total mass of the wet sheet for cleaning.
YARN MANUFACTURED FROM RECYCLED CLOTHING FIBERS AND PROCESS FOR MAKING SAME
Yarn manufactured from recycled mixed clothing fibers and a process of making yarn manufactured from recycled mixed clothing fibers. Upcycled yarn has approximately 70%-95% of fiber from separated used clothes fibers, whereby separated used clothes fibers have cotton, polyester, nylon, silk, rayon, spandex, synthetic fibers, wool, hemp, carbon fibers, and/or linen. The upcycled yarn also has approximately 5%-30% other fibers that can be recycled fibers and/or virgin fibers, whereby the recycled fiber is recycled polyester from recycled plastic bottles and other sources, recycled cotton, recycled nylon from fishing nets and other sources, and the virgin fiber is nylon, spandex, virgin polyester, hemp, carbon fiber, and/or organic cotton.
Direct Deposition of Nanofiber on a Textile Substrate
A method of manufacturing a composite textile fabric is provided. The method includes the step of simultaneously forming and depositing fine fibers on a textile. The textile is at least one of a woven fabric, a knit fabric, and a fleece fabric. The fine fibers have an average diameter of less than 1.2 micron. The method also includes the step of bonding the fine fibers to form a membrane layer on the textile.
Bonded Insulation Product Batt from Spent Carpet and Waste
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.
Cosmetic
An elastic body for cosmetic holding use which can be used for holding a cosmetic such as a foundation, such as a puff that can be used for the application of a cosmetic onto skin, said elastic body being characterized by containing conjugate fibers as constituent fibers, wherein each of the conjugate fibers contains a resin A and a resin B having a higher melting temperature than that of the resin A, and contact parts between the constituent fibers are integrated with the resin A contained in the conjugate fibers; a cosmetic-containing elastic body which comprises the elastic body for cosmetic holding use and a cosmetic contained in the elastic body; and a cosmetic equipped with the cosmetic-containing elastic body.
