Embodiment 1

[0224] Flame Retardant Chemicals Containing Water of Hydration

[0225] The sliver is prepared such that it has a low twist (about 4 twists per meter) and weighs 3 to 8 grams per meter. The sliver can be made from any staple fiber such as, but not limited to, cotton, rayon, polyester and nylon. The sliver is run through the system as described, but before the sliver is placed in the channel of the belt, a small amount of a flame retardant (FR) chemical compound in the form of a fine powder (typically no larger than 5 microns in size) is placed in the water, The water is sprayed on the fibers. It should be noted that FR can also be placed on a dry strip. When the radio waves are turned on, the powder is mixed into an aqueous carrier. The powder may be any hydrated insoluble compound such as, but not limited to, sodium borate decahydrate or alumina trihydrate. In this case, the inventors used a combination of alumina trihydrate and magnesia, and in a second example sodium bo...

Embodiment 2

[0231] Preparation of sliver incorporating individual fibers associated with metals and metal oxides

[0232] The sliver is prepared such that it has a low twist (about 4 twists per meter) and weighs 3 to 8 grams per meter. The sliver may be made from any staple fiber such as, but not limited to, cotton, rayon, polyester or nylon. The sliver is run through the system as described, but before the sliver is placed in the channel of the belt, a very small amount of the intended compound in the form of a fine powder (typically no larger than 5 microns in size) is placed in the water and the chemical delivery tank (32) or placed on a dry belt. The powder should be zinc or any form of zinc, such as zinc oxide, but in a preferred embodiment should be zinc oxide at a purity level of not less than 97%. Other metals and metal oxides may be used, such as copper and / or its oxides or silver and / or its oxides. The amount of predetermined chemical compound is not critical, since the fiber...

Embodiment 3

[0244] Embodiment 3 (diatomaceous earth and organic insoluble compound)

[0245] The sliver is prepared so that it has a low twist (about 4 twists per meter) and weighs from about 2 to about 20 grams per meter, and preferably from about 3 to about 8 grams per meter. The sliver can be made from any staple fiber such as, but not limited to, cotton, rayon, polyester and nylon. The sliver is run through the system as described, but before the sliver is placed in the channel of the belt, a very small amount of the intended compound in the form of a fine powder (typically no larger than 5 microns in size) is placed in the water and the chemical delivery tank (32) or placed on a dry belt. The powder can be food grade diatomaceous earth with a purity level of not less than 97%. Diatomaceous earth was chosen for this example because it is EPA-approved as an insecticide for use against common bed bugs, temperate bed bugs (Cimexlectularius), and other exoskeletal pests such as fleas, t...

Abstract

The present invention relates to a surface treatment and a method for its application for the introduction of a wide variety of differentiating properties to fibersin sliver form through a surface treatment of said fibers. The system can accommodate chemical processes, sonochemical processes, and acoustic cavitation processes whereby the fibers are speckled or plated with at least one predetermined compound in a liquid medium to impart at least one desired property to the fibers and for the orderly inclusion of such treated fibers in sliver form having such properties in yarns, woven, knit, or non-woven textiles.

Description

[0001] The present invention relates to the surface treatment of individual yarns prior to converting them into yarns or fabrics, and systems for fiber treatment. This system allows individual fibers to be treated with multiple compounds that impart different properties to individual fibers through surface treatment of the fibers. The system uses fibers in the form of sliver. The system can be adapted for chemical treatment processes, sonochemical processes, and acoustic cavitation processes by which individual fibers are spotted or plated with at least one predetermined chemical compound or composition in a liquid medium that can Comprising 1% w / w or more of a compound or composition that imparts at least one desired property to the treated fiber without the need for a binder. The system facilitates the ordered positioning of fibers, enabling their inclusion in yarns, woven, braided or nonwoven fabrics prepared by existing conventional manufacturing processes, thereby providin...
