TAMPON WITH NATURALLY HYDROPHOBIC COMPONENTS
20230381030 · 2023-11-30 ·

A tampon comprising an absorbent pledget and a withdrawal cord attached to the pledget is disclosed. The withdrawal cord may be constituted predominantly (by weight) of natural plant fiber such as cotton, and comprise no more than 5 percent by weight material derived from petroleum, while exhibiting limiting wicking capability. A method for manufacturing tampons with withdrawal cords including cotton fiber is disclosed, including a scouring step in which the scouring solution is of relatively lower pH than is conventional for scouring cotton, is disclosed.

METHOD FOR MAKING ANTIMICROBIAL ARTICLE

A method of making an antimicrobial textile comprising TiO.sub.2 nanoparticles is described. The TiO.sub.2 nanoparticles are immobilized by first treating a textile with a base, and then contacting with TiO.sub.2 nanoparticles in a solution of an alcohol and acid. The textile may be subsequently irradiated with UV light prior to use. The antimicrobial textile shows high effectiveness against the growth and proliferation of microorganisms transmitted within indoor environments.
