METHOD AND SYSTEM FOR THE APPLICATION OF CHEMICAL COMPOUNDS TO NATURAL FIBERS AND TREATED FIBERS OBTAINED THEREFROM
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.
METHOD OF CHEMICAL TREATMENT ON NONWOVENS
Nonwovens having low-density and resilience have a chemical formulation applied on one surface (e.g., a top surface) by any of various application methods. Then, the chemical formulation is forced to move toward the opposite surface of the nonwoven (e.g., move downward through the nonwoven from top to bottom). The chemical-treated nonwoven is dried to fix the chemical on the nonwovens. Movement through the nonwoven is performed in a controlled fashion so that after drying the distribution of a chemical formulation throughout the nonwoven (e.g., from the top surface to the bottom surface of a nonwoven) is controlled.

FABRIC FOR AIRBAG, COATED FABRIC FOR AIRBAG, AND AIRBAG USING SAME
Problem: To provide an airbag fabric and a coated fabric for airbags that are lightweight and compact while maintaining the tensile strength required for airbags, and that can mitigate damage to seams of an airbag when the airbag deploys; and that allow for stable airbag deployment.
Solution: An airbag fabric that is a fabric comprising a synthetic fiber, the fiber that constitutes the fabric having a total fineness of 200 to 400 dtex, an average edgecomb resistance retention in the warp and weft directions after heating at 210 C. for 30 seconds of 60% or more, and a residual shrinkage of 1.5% or less in both the warp and weft directions.

Anti-Ozone Treatment of Base Templates in Laser Finishing
Indigo-dyed garments are treated with an anti-ozone agent to prevent ozone-related degradation of the garments before laser finishing. Without treatment, the garments can exhibit color loss (e.g., color change or fading) from exposure to ozone in the atmosphere. The indigo-dyed garments with anti-ozone treatment can serve as base templates in a laser finishing process flow. The anti-ozone treatment of the base templates can include a rinse including an ascorbic acid or vitamin C constituent during a base preparation process. Then quantities of these base templates can manufactured and stored for periods of time without exhibiting ozone-related degradation effects.
