History of meltblown process

 

      R&D of meltblown process started in 1940’s. The first kind of microfiber based on the melt-blow principle was made of inorganics.

On the other hand, R&D work of the organic microfiber started in 1951 at a laboratory of US Navy, which successfully established the technological fundamentals of meltblown process. Exxon then inherited this technology, and started R&D effort in 1965 to manufacture nonwoven microfiber with polypropylene (PP). However, Exxon withdrew from it in 1973, and provided the technology license to several ventures for commercialization.

Hence, Exxon’s nonwoven fiber technology of PP is yet a mainstream of the meltblown process.

In Japan, Tonen Sekiyu Kagaku (now Tonen Kagaku GK) which was then an Exxon affiliate company in Japan, inherited this technology and commercialized the nonwoven product.Tonen Tapyrus Co. Ltd. (a predecessor of Tapyrus Co. Ltd.) further inherited the nonwoven business and technology.
