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.

An extraction sheet having high machinability in the manufacture of an extraction filter for beverages and an extraction filter using the same and having high handling property is provided. The extraction sheet includes a layer including a meltblown nonwoven fabric that is formed from fibers of a polylactic acid-based resin having a crystallinity of 9.0% or lower and a fiber diameter of 15.0 m or smaller and that has a basis weight of 2.0 to 30.0 g/m2, and a layer including a spunbonded nonwoven fabric that is formed from fibers of a polylactic acid-based resin having a crystallinity of 30.0 to 60.0% and a fiber diameter of 35.0 m or smaller and that has a basis weight of 5.0 to 30.0 g/m2. The extraction sheet has a bending hysteresis of 5.010.sup.3 to 14.510.sup.3 gf.Math.cm/cm.

In some implementations, printer roller cleaning sheets may include a nonwoven fabric having a blend of polyester fibers and cellulose fibers, the nonwoven fabric being in the form of a continuous sheet wound around a core, the nonwoven fabric designed and configured to effectively remove debris from printer rollers, the roll of polyester cellulose material configured to replace a roll of paper in the printer in order to perform a cleaning function of the one or more printer rollers.

A system for creating a blended fiber pad made from a mixture of alpaca fiber and a selected fiber. The fiber pad is used for bedding products, cushions, toppers and furniture. The system includes a washing station for cleaning and processing the fiber mixture and a pad forming machine. The washing station is used to thoroughly wash, clean and dry the alpaca fiber and the selected fiber. The washing station includes a series of wash tanks, squeeze pads and drying racks. The dried alpaca fiber and dried selected fiber are then baled and fed into the pad forming machine. The pad forming machine includes a plurality of individual sections with a series of conveyor belts. The conveyor belts are used for conveying the fiber mixture and a bond material from one station to the next and creating a finished blended fiber pad.

The present invention relates to wadding in which short fibers (A) having a single fiber fineness (a) of 0.001-1.0 dtex make up 5-90 mass % of the total mass of the wadding. Measured in accordance with JIS L 1096 Warmth Retention Method A (Constant-Temperature Method):2010, a 89% or higher warmth retention ratio is obtained in test items made by stuffing 100 g of the wadding substantially evenly into a pouch-shaped cover produced by layering two pieces of 45 cm-length 100% cotton fabric squares and thereafter sewing shut the opening of the pouch-shaped cover. By means of the present invention, it is possible to provide wadding which has excellent softness and bulkiness and which is ideal for use in down jackets, duvets or other bedding.

A liner, comprising a layered material in which a carded nonwoven wadding is thermally bonded to a thin carded nonwoven top layer, for upholstered furniture. In the liner, a high proportion of the staple fibers in the top layer are thin bi-component binder fibers. Further, at least 20 wt % of the staple fibers in the wadding is thick staple fibers. Furthermore, also the wadding comprises bi-component binder fibers.
