Antibacterial twisted yarn, and antibacterial yarn and antibacterial cloth including antibacterial twisted yarns

This invention describes a special antibacterial yarn made by twisting two different fibers together. One of these fibers is a "piezoelectric" material, which means it creates a small electrical charge when it's moved or squeezed. This charge is what makes the yarn antibacterial. Specifically, the main fiber is the charge-generating one, twisted at a specific angle, and the second, shorter fiber is not piezoelectric but is more water-attracting.

Why it matters: Since 2020, progress in developing more efficient or cost-effective piezoelectric fiber materials may have made this technology more practical. Additionally, improved methods for integrating functional fibers into textiles could simplify manufacturing.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPiezoelectric fibers, specialized yarn twisting
