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.
MODIFIED CELLULOSIC FIBERS
The disclosure provides a fibrous material comprising a plurality of fibers, the fibers being natural or synthetic cellulosic fibers or natural or synthetic protein fibers, and wherein the fibers are treated with a cationic compound. The disclosure also provides a method for imparting improved compatibility with quaternary ammonium compounds to a fibrous material, including: providing a fibrous material comprising a plurality of fibers, the fibers being natural or synthetic cellulosic fibers or natural or synthetic protein fibers; optionally, pre-treating the fibrous material with a base; treating the fibrous material with at least one cationic compound to impart improved compatibility with quaternary ammonium compounds; and optionally, further treating the treated fibrous material with a polymer or resin.

FLAME RETARDANT MATERIAL AND SYSTEM
Systems, apparatuses, and methods are described that combine a sorbent containing a flame retardant with a substrate, which is capable of responding to temperature increases to prevent, suppress, delay the spread of, or otherwise mitigate a proximal thermal event. A flame retardant system has a flame retardant material that is incorporated into a matrical sorbent material, which is incorporated into a substrate. The matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature, e.g., a temperature that is greater than 300° C. in one embodiment.
Modified polyester fiber for cementitious composite and method for surface treatment of the same
The disclosure relates to a method for the surface treatment of a polyester fiber, a modified polyester fiber obtained therefrom, and an engineered cementitious composite containing such modified polyester fibers. The method comprises subjecting the polyester fiber to an alkali hydrolysis to obtain hydrolyzed polyester fiber; applying a solution containing an acid cross-linker and a polyvinyl alcohol to the hydrolyzed polyester fiber, then curing to form a coating having a thickness of sub-micron or micron scale on the polyester fiber, thereby obtaining the modified polyester fiber.
Coated Antimicrobial Fabric
A nonwoven fabric has active antimicrobial and anti-viral agents coated onto it. Alternatively, an active antimicrobial/antiviral agent may be mixed into the barrier coating or fiber polymers themselves that make up the nonwoven material. A primary example is the treatment of an existing fabric having known permeability appropriate for an intended use. Intended uses for this nonwoven fabric include, but are not limited to, as a wearable garment, hair coverings, “booties,” temporary curtains, instrument wraps, surgical drapes, and blankets, each of which has active antimicrobial protection, thereby allowing the possibility of multiple uses of the fabric product.

Preparation method of safety gloves with special coating
The present invention relates to safety gloves with special rubber coating. Specifically, a kind of safety gloves with rubber coating which is specially designed and coated on fabric substrates to achieve proper hand protection effects, and exhibits properties such as good ventilation, abrasion resistance, and soft and comfortable wearing experience. A preparation method of safety gloves with special coating, comprising following steps: (1) treating a substrate with composite electrolyte digestion solution by a certain method; (2) spreading polymeric disperse coating over the substrate containing composite electrolyte digestion solution obtained in step (1), heating when the polymeric disperse coating is attached and obtaining a half-product with polymeric disperse coating; (3) treating the half-product with polymeric disperse coating in pre-foamed water chemical compound or non-foamed water chemical compound, by treating immersing or spraying or immersing and spraying is defined; and (4) dipping the product treated in step (3) in aromatic hydrocarbon solution.
PROCESSES FOR PREPARING INORGANIC CARBONATES
The present invention aims to provide techniques for efficiently synthesizing inorganic microparticles. According to the present invention, inorganic carbonate microparticles can be synthesized by generating ultrafine bubbles containing carbonic acid gas by injecting a gas containing carbonic acid gas and a liquid into a reaction vessel through a nozzle to deposit an inorganic carbonate having an average primary particle size of 300 nm or less in the presence of the ultrafine bubbles.
