Abstract:
An antimicrobial filter cartridge having a microporous core member about which is applied a yam which may be impregnated with a 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 bacteria and other contaminants from the water and which prevents the growth of bacterial and other microorganisms on the filter media.
Abstract:
This invention generally relates to the production of a composite yarn or non-woven strand wherein a core of super absorbent fibers or polymers (SAP's) having a swell factor of approximately 25% 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.
Abstract:
A process for producing yarns that have enhanced resistance to unraveling and linting. 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 spun yarn formed with a core of microdenier synthetic filaments wrapped with a sheath. The sheath generally includes carded staple fibers that are spun around the core.

Abstract:
A heat and flame resistant sewing thread having a core of glass filaments wrapped with a sheath of fibers spun about the core and having a lubricant applied therealong.
Abstract:
An antimicrobial filter cartridge having a perforated core member wrapped with a first microporous membrane, which is in turn overwrapped with second and third microporous membranes. The membranes are covered with a criss-cross wrapping of antimicrobial treated yarn. 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 microorganisms from the water and which prevents the growth of bacterial and other microorganisms on the filter media.
Abstract:
An antimicrobial filter cartridge having a perforated core member wrapped with a microporous membrane, which is overwrapped with a spiral wrapping of an antimicrobial agent impregnated yarn. The spiral wrapping is covered with a criss-cross wrapping of yarn. 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 microorganisms from the water and which prevents the growth of microorganisms on the filter media.
