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.
Abstract:
The invention provides a thermal control combination yam system comprising a first plurality of the yams within said system comprising microdenier or almost microdenier hydrophobic yams, such as, for example, polypropylene (PP), and a second plurality of the yams comprising less hydrophobic ultra microfibres (UMF). Said system comprises a ratio of said yarns ranging from between 97% yams comprised of a microdenier or almost microdenier hydrophobic material and 3% yams comprised of ultra microfibres (UMF) comprised of a less hydrophobic material to 97% yams comprised of ultra microfibres comprised of a less hydrophobic material and 3% yams comprised of a microdenier or almost microdenier hydrophobic material and said first plurality of yams is in direct contact with said second plurality of yams.

Abstract:
The present invention relates to a multilayer protective mask having antimicrobial properties, said mask comprising a body portion comprising: at least a first and a second fabric layers having random fiber configuration; a middle layer comprising a nanofiber membrane; and a third and a fourth fabric layers. The first fabric layer is disposed between the third fabric layer and the nanofiber membrane, and the second fabric layer is disposed between the fourth fabric layer and the nanofiber membrane. The first, the second, the third, and the fourth fabric layers have incorporated therein a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, said combination having synergistic antimicrobial properties.
Abstract:
There is provided an impregnated natural fiber including a cuticle and an interior lumen, the cuticle circumscribing the interior lumen; and insoluble particulates possessing a preselected property embedded in the fiber. The particulates comprise at least 0.1-30 wt.% of the impregnated fiber and the particulates are embedded on the cuticle and within the lumen of the fiber. The fiber has an increased strength, micronaire value and rate of water absorption. Also provided is a system for surface treating cellulose sliver fibers. The system includes a vessel containing a moist paste which comprises at least one particulate material possessing one or more preselected desired properties, a thickening agent and water. The paste from the vessel is dispensed directly onto sliver fiber ribbon(s). A bore sonotrode generates ultrasonic waves which embed the particulate material(s) in the sliver fibers.
