A method of preparing polyurethane prepolymer does not require using a toxic isocyanate monomer (manufactured by harmful phosgene) as a raw material. Epoxy resin and carbon dioxide are used as major raw materials to form cyclic carbonates to be reacted with a functional group oligomer, and then amino groups in a hydrophilic (ether group) or hydrophobic (siloxane group) diamine polymer are used for performing a ring-opening polymerization, and the microwave irradiation is used in the ring-opening polymerization to efficiently synthesize the amino-terminated PU prepolymer, and then an acrylic group at an end is added to manufacture an UV cross-linking PU (UV-PU) oligomer which can be coated onto a fabric surface, and the fabric is dried by UV radiation for a surface treatment to form a washing-resisted long lasting hydrophilic or hydrophobic PU fabric.

A method of making a fluorinated fibrous web, which method includes providing a nonwoven web 22 that contains polymeric fibers, creating a plasma that contains fluorine atoms at a first location 14 , and contacting the nonwoven web with products from the plasma at a second location 26 remote from the first location 14 . The method avoids exposure of the web to the plasma and hence expands the manufacturing processing window. Webs so fluorinated have a different C 3 F 4 H + to C 2 F 5 + ratio when compared to locally fluorinated webs having similar levels of surface fluorination. The remote fluorinated webs can be subsequently charged electrically to provide a good performing electret filter 40 suitable for use in an air purifying respirator 30 . Webs fluorinated in accordance with this invention also may exhibit good performance even after being “aged” at high temperatures.

A method of making a fluorinated fibrous web, which method includes providing a nonwoven web that contains polymeric fibers, creating a plasma that contains fluorine atoms at a first location and contacting the nonwoven web with products from the plasma at a second location remote from the first location The method avoids exposure of the web to the plasma and hence expands the manufacturing processing window. Webs so fluorinated have a different CFH to CF ratio when compared to locally fluorinated webs having similar levels of surface fluorination. The remote fluorinated webs can be subsequently charged electrically to provide a good performing electret filter suitable for use in an air purifying respirator Webs fluorinated in accordance with this invention also may exhibit good performance even after being “aged” at high temperatures. 1.
