Abstract:
A pellet made from paper particulate extruded and cut into pellets, the pellet comprising an elongated form having opposite flattened surfaces separated by a pellet thickness. Also described is a process for producing paper particulate pellets comprising: extruding processed paper particulate into pellets having an elongated form; and flattening the extruded paper particulate such that the pellets have opposite flattened surfaces.
Abstract:
The invention relates to a spun yarn comprising at least one natural fiber and staples of a high strength polyethylene fiber, wherein the high strength polyethylene fiber has an initial modulus of at least 40 GPa and a tensile strength of at least 1.4 GPa, wherein the yarn comprises between 1 and 4% by weight staples of the high strength polyethylene fiber. The invention also relates to a fabric comprising the spun yarn and articles comprising said spun yarn or said fabric.
Abstract:
A cord for reinforcing rubber articles according to the present invention is formed by a thread with ply-twisted cellulose fiber twisted with a thread of ply-twisted nylon fiber. The ply twist number of the nylon fiber is less than the ply twist number of the cellulose fiber. A pneumatic tire according to the present invention uses the cord for reinforcing rubber articles according to the present invention in a ply cord of the carcass.
Abstract:
The invention relates to a textile substrate (1) comprising warp and weft, wherein the warp comprises a plurality of warp threads (K26-K34) and the weft comprises a plurality of weft threads (S29-S30), wherein each warp thread crosses over a plurality of weft threads and each weft thread crosses over a plurality of warp threads, such that the warp and the weft jointly form a layer that has a first surface (2-1) and a second surface (2-2) opposite the first surface. At least one of the weft threads (S29) consists of a first yarn (15) and at least one weft thread (S30) consists of a second yarn (16). The first yarn (15) is a three-component yarn, which comprises fibres of wool and regenerated cellulose and at least one third fibre in the form of a continuous fibre made of a synthetic material. The second yarn (16) contains regenerated cellulose fibres, wherein the mass fraction of the regenerated cellulose fibres contained in the second yarn with respect to the total mass of the second yarn is greater than the mass fraction of the second fibres of regenerated cellulose contained in the first yarn with respect to the total mass of the first yarn. In the case of the at least one weft thread (S29) consisting of the first yarn (15), the overall length of all those longitudinal sections that run at the first surface (2-1) is greater than the overall length of all longitudinal sections that run at the second surface (2-2). In the case of the at least one weft thread (S30) consisting of the second yarn (16), the overall length of all those longitudinal sections that run at the first surface (2-1) is smaller than the overall length of all longitudinal sections that run at the second surface (2-2).
Abstract:
Fire resistant garments are disclosed made from a fabric containing a fiber blend. The fiber blend contains meta-aramid fibers, fire resistant cellulose fibers, non-aromatic polyamide fibers, and optionally para-aramid fibers. The non-aromatic polyamide fibers are present in an amount sufficient to dramatically improve the abrasion resistance of the fabric without adversely interfering with the flame resistant properties. In addition to abrasion resistance, the particular blend of fibers has also been found to dramatically improve or increase various other properties. In one embodiment, the fabric is made with a herringbone weave which has been found to unexpectedly improve tear properties and porosity.
Abstract:
The invention relates to a biodegradable flexible textile comprising long elements, such as yarns, staples or narrow fabrics, which are interlaced or crossed with one another and which are obtained from fibres of paper or a non-woven cellulose fabric, preferably originating from conifers. The textile can comprise treatments in order to increase cosmic radiation filtering properties and treatments with fire-retardant, water-repellent, fungicidal, bactericidal or dying substances. The invention also relates to the use of said textile in order to cover the internal surfaces of vehicles and aircraft or as a cover for glasshouses, tents and similar.
Abstract:
The present invention is directed to a method of making at least a portion of a garment that includes at least one three-dimensional contour. The disclosed method includes providing a fiber and solvent mixture that includes fibers and a solvent capable to causing a plurality of covalent bonds to be created between the fibers. In many embodiments, the plurality of covalent bonds form when a catalyst, such as heat, is provided to the fiber and solvent mixture. The process can be performed using, for example, either a 3D printer or mold form. The fibers used can be natural, synthetic, or a blend of natural and/or synthetic fibers. The solvent preferably includes ionic salts in water.
Abstract:
The present invention relates to a method for manufacturing a shaped body comprising lignin which may be further processed into intermediate carbon fibers and finally also carbon fibers. Uses of said fibers are also disclosed. The present invention addresses the problem of lignin leaching into a precipitation bath. The solution to this problem is a novel method for minimizing the loss of lignin through the addition of certain salts into the precipitation bath.
Abstract:
Acid-resistant and biosoluble glass compositions and products made therefrom. The glass compositions exhibit acid resistance, durability in white water as may be used in a wet laid fabrication process, and good biosolubility. In another aspect, a glass fiber mat is made from such a glass composition, and may be used in the manufacture of lead-acid batteries, for example as a pasting material or battery separator.
Abstract:
Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.
