Abstract:
A V-ribbed belt has a cord made of polyester-based fibers, the total fiber fineness of which is 2200 dtex or more and 5500 dtex or less. A fiber fineness of the cord per belt width corresponding to a single V-shaped rib ranges from 10000 dtex to 19000 dtex. A belt dry-heat shrinkage force per belt width corresponding to a single V-shaped rib is 44 N or more. The belt dry-heat shrinkage force is a load increase with respect to a belt length of 300 mm in 30 minutes after applying, in an atmosphere of 150° C., a load of 6N in the belt longitudinal direction and holding the belt.
Abstract:
The present invention relates to a cap ply reinforcement hybrid yarn (1) which is located between the tread and the belt package especially in radial passenger vehicle tires, which improves the high speed durability of the tire by using polyamide (N)/polyester (P) yarns, and which provides fuel saving by decreasing the rolling resistance.
Abstract:
The present invention provides a cotton-like knitted fabric, a polyester filament and a production method. The fabric is a weft-knitted fabric obtained by material containing at least above 45% by weight of polyester filaments; the pore area distribution of the fabric is centered on 6000 to 22000 μm2 and has a statistical variability of above 2a, and the coefficient of variation of the pore area is greater than 40%. The polyester filament is formed from alternatingly arranged twist regions in a false-twist direction and twist regions in an opposite direction, wherein the twist regions in the false-twist direction have an average length of less than 0.3 cm, a coefficient of variation of length of above 60%, a diameter that is 30% to 70% of the diameter of the twist regions in the opposite direction, and a total length that is 20.0% to 40.0% of the total length of the polyester filaments.
Abstract:
A method of manufacturing multi-ply separable textured yarn, the method comprising, passing a multi-ply separable interlaced filament yarn through a texturizing unit to form a multi-ply separable draw textured yarn, wherein the multi-ply separable interlaced filament yarn is separable in to at least two separable interlaced filament yarn, wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric.
Abstract:
A method for manufacturing a cord yarn, which has at least one filament strand, includes applying a first twist so that a K1 value has a value of 0.1837763/D1n or below, applying a second twist so that a K2 value has a value between 0.0166819/D2n and 0.3183099/D2n, and applying a third twist so that a K3 value has a value between 0.0278485/D3 and 0.2968288/D3, wherein the twists are applied so that the cord yarn has roundness of 50% or above, and when the filament is a multi filament, so that porosity between strands of the cord yarn is less than 40%.
Abstract:
A nanofiber forest on a substrate can be patterned to produce a patterned assembly of nanofibers that can be drawn to form nanofiber sheets, ribbons, or yarns.
Abstract:
A facility for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements, in which each of the first and second assemblies includes a plurality of filamentary elements wound together in a helix, includes an assembling apparatus and a splitting apparatus. The assembling apparatus of the facility assembles M filamentary elements together into a layer of M filamentary elements around a temporary core, to form a temporary assembly. The splitting apparatus of the facility splits the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.
Abstract:
Spun yarns, fabrics, and garments with a balance of high thermal and comfort properties are disclosed. Spun yarns made with an intimate blend of fibers including flame resistant fiber, hydrophilic fibers, and anti-static fibers are described. The unique combination of fibers in the spun yarn and fabrics made therefrom provide a balance of high thermal properties, including flame resistance and thermal shrinkage resistance, as well as moisture management properties to provide both protection and comfort to the wearer. In addition, a spun yarn and fabric made therefrom may be dye accepting and/or can be printed thereon. In one embodiment, printable or dye accepting aramid fiber, or producer dyed meta-aramid is utilized in the spun yarn. A fabric made with the spun yarn may have pre-wash softness that makes it comfortable to wear.
Abstract:
A device including an array of aligned conductive channels. The conductive channels are operable for directional transport of species selected from the group consisting of electrons, ions, phonons, and combinations thereof. The conductive channels are provided for by nanofibers in a form selected from the group consisting of ribbons, sheets, yarns, and combinations thereof.
Abstract:
The invention relates to a method for producing a towel, specifically a low twist towel, comprising the following steps: Z twisting a thick yarn and separately Z twisting a fine count yarn; unevenly S twisting the Z-twisted yarns to make the volume of the thick yarn more than that of the fine count; weaving the yarn to produce a fabric; processing the fabric with hot water to reduce inner tension in the yarn and make the fabric become fluffy. Fabric produced by this method can solve the dependency on PVA, reduce energy consumption and material consumption, and prevent water pollution. This method for producing a low twist towel is environmentally friendly, healthy, and energy saving.
