Sulfonated polyester resin, easily dyeable polyester fiber, antibacterial material, antistatic material, and method for producing these

摘要

The invention relates to sulfonated polyester resin having sulfone group, and easily dyeable polyester fiber, antibacterial material and antistatic material which can be used for various clothing and building materials. The sulfonated polyester resin is formed by treatment of the polyester resin with anhydrous sulfuric acid, and the easily dyeable polyester fiber contains the sulfonated polyester resin, the antibacterial material and the electrostatic material The sulfonated polyester resin and the organic base ion bonded to the sulfone group are contained. The antibacterial material and the antistatic material take the form of fiber, cloth, knitting, and cotton, etc., and the antibacterial material further forms the sheet and film.
