Abstract:
A heat and flame resistant sewing thread having a core strand formed of glass material filaments is wrapped with a sheath of staple fibers spun about the core strand A lubricant is applied along the core strand to assist in the wrapping of the core strand with the sheath fibers. The sheath fibers include a series of microdenier fibers and generally will be ring spun about the core strand.
Abstract:
The present invention discloses and claims an absorbent article which utilizes an adsorbent portion that includes polyamide wicking yarns, polyamide fibers, and/or polyamide fabrics with or without non-wicking yarns, fibers, or fabrics as part of the absorbent portion such that liquid is wicked to selected regions of the absorbent portion. The present invention may also include non-wicking yarns or fibers or non-woven fabrics that are primarily non-wicking cellulose. The wicking rate and fluid capacity of the polyamide wicking yarn, polyamide fibers, and/or polyamide fabrics change with the ratio of polyamide wicking and non-wicking fibers including cellulose fibers. Further, the absorbent portion may be a blend of polyamide wicking yarns, polyamide fibers and/or polyamide fabrics with non-woven wicking fabrics and/or non-wicking cellulose yarns, fibers, or fabrics.
Abstract:
A yarn is provided which includes a core and a wrapping yarn wound about the core. The core may include glass, metal and carbonaceous fibers which may be roughened and/or stretch-broken. The yarn may exhibit enhanced performance properties, such as strength, cut resistance and heat resistance. A method of making the yarn includes combining a glass filament and metal filament in a core wrapped by a sheath.
Abstract:
A yarn is provided which includes a core formed of a glass material and a wrapping yarn wound about the core. The core has a roughened surface, which tends to engage and hold the wrapping yarn. The yarn may exhibit excellent strength, cut resistance and heat resistance, while providing a smooth finish. A method of making the yarn includes roughening the surface of the glass filament by various means.
Abstract:
A bacteriostatic filter cartridge having a porous core member about which is layered a yarn and/or a polyester membrane and/or melt blown web of polypropylene and/or a trilaminate polypropylene membrane, any or all of which may be impregnated with an antimicrobial agent. The filter cartridge is sized so as to fit tightly into a cartridge housing of a fluid filtration system. Fluid passing through the cartridge housing will be filtered by the filter cartridge to remove contaminants from the water and which prevents the growth of bacterial and other microorganisms on the filter media.
Abstract:
The present invention is directed to mop heads which comprise polyester wicking fibers which assist in absorbing, holding, and applying disinfectant/antimicrobial composition without removing the active disinfectant such as quaternary ammonium salts from the composition.
Abstract:
A process for producing yarns that have enhanced resistance to unraveling and linting, wherein the yarns are moved along guides through a needle loom where a series of needles engage the yarns. This engagement of the yarns by the needles causes the fibers of the yarns to become intermixed.
Abstract:
A moisture-retentive fabric medium includes a hydrophilic, thermoplastic polyester fiber as a blend of from 10-905% or 20-80% by total weight of textile fibers and 90-10% or 80-20% by total weight of hydrophilic textile fibers and less than 0.5% by weight of total fabric medium as microfibrillated cellulose fiber and less than 0.05% by weight superabsorbent polymers, the polyester having a melting point between 190-500 F when measured in accordance with ASTM D-3418.
Abstract:
A mop yarn formed with a core of microdenier synthetic filament fibers wrapped with a sheath. The sheath generally includes carded staple fibers spun around the core.
Abstract:
This invention generally relates to the production of a composite yarn or non-woven strand wherein a core of super absorbent polymer fibers (SAP's) having a swell factor of approximately 250% and greater are encapsulated by a nonwoven membrane of defined porosity. The membrane is then sealed in a fashion to generally deter or prevent the SAP material from migrating out of the core as water is freely absorbed and desorbed from the composite yarn structure. The strands of yarns or strips of non-woven material are subsequently constructed into an open or unorientated fabric formation. When used as a subterranean fabric, structure or material, the resultant fabric structure retains moisture while permitting normal root growth and allowing excess water to pass through and beneath the fabric while facilitating movement of water from lower levels to the surface.
