Latest Patents
Among his latest patents, two notable inventions stand out:
1. **Wettable Polyolefin Fiber Compositions and Method**: This patent features compositions of ethylene alkyl acrylate grafted onto polyolefin, such as isotactic polypropylene. The highly wettable composition incorporates a polar group material and a hydrophilic modifier that consists of a monoglyceride and a salt of a linear alkyl. The method involves extruding the polyolefin into a spinnable fiber, which can be used to create woven or nonwoven materials. The products derived from this composition are particularly useful for manufacturing diaper coverstock, personal hygiene pads, battery separators, tea bag pouches, and filter stock.
2. **Dyeable Polyolefin Compositions and Method**: This patent addresses compositions of ethylene alkyl acrylate grafted onto polypropylene that can be dyed using disperse or cationic dyes. Incorporating a small amount of polyester and a hydrophilic modifier helps bridge the polyester and polypropylene. The dyeing method consists of combining polypropylene with a thermoplastic copolymer of ethylene and alkyl acrylates, spinning the resulting fibers, and treating them in a dye bath to achieve the desired coloring. A sulfonic group may be added to enhance compatibility for cationic dye exposure.
