Abstract: A method of making a phosphonated polybenzimidazole fiber comprises the steps of: spinning an untreated PBI resin into a PBI fiber; treating the PBI fiber with phosphoric acid, and thereby obtaining a PBI fiber with 1-25 wt. % phosphoric acid APU. A fiber is made with a polybenzimidazole (PBI) polymer with a phosphoric acid pick-up (APU) in the range of 1-25% (PBI-p fiber). The PBI-p fiber may have a LOI≥50% and/or an initial thermal decomposition temperature in air of ≥555° C.

Abstract: A sodium silicate polymerization method was used to incorporate sodium silicate and/or other water soluble inorganic fire retardants into an insoluble matrix. By using a vacuum/pressure technique, a water soluble sodium silicate/borate mixture was forced into the interior of various cellulosic materials, then was heat polymerized into an insoluble fire retardant matrix. This produced a dual action fire retardant material also with the following properties: moisture resistant, weather proof, and improved strength. Water insoluble forms of sodium silicate and borates have not been possible until now. This process and testing was then repeated with six other water soluble fire retardant combinations, making them similarly water insoluble. The process was used to incorporate water soluble substances into the intercellular structures of cotton fibers, polymerized to the insoluble form in the interior, thus becoming trapped inside the fibers, producing weavable fibers, that were flexible, very strong and highly fire retardant. Because some of the best fire retardants are water soluble inorganic compounds, from both fire retardant and environmental considerations, until now, the problem of water solubility has greatly restricted the widespread use of the water soluble inorganic fire retardants. The present invention provides a very promising approach for solving this problem while providing the added properties of increased strength. It was further found that chemicals and substances could be forced to penetrate cellular interiors, and further that reactions could be caused to occur within the cells by the choice of materials, chemicals, and conditions of the infusion process.

Abstract: This invention relates to a manufacturing process of synthetic yarn and the produced yarn which has superior texture and brightness, and excellent color developing, hygroscopicity, and anti-static properties. A plurality of monofilaments is drawn out at an appropriate speed, dried and heated. Then a property enhancing agent containing a metallic salt, alcohol, optional solvent and optional additional functional agent, such as a hygroscopic agent, ultraviolet protecting agent, or resist agent, etc. is applied onto the surface of the filaments which are melted and flame bonded to each other. Multi-filaments are formed with spaces therebetween in which the functional agent remains inserted. The new synthetic yarn is produced after the multi-filaments are subjected to washing, drying and take-up procedures.
