20080230471 | FUNCTIONAL FILTER MEDIUM - This invention relates to functional nonwoven filter media provided by radiation-induced graft copolymerization and its production method. Meltblown type of nonwoven (Meltblown) comprised of fine fibers, less than 8 micron in diameter, of polyolefin or polyamide is chosen as the suitable grafting trunk polymer. The production methods are composed of following steps, 1) irradiation less than 30 kGy dose to the Meltblown with electron beam or gamma ray; 2) graft copolymerization of emulsified vinyl monomer onto the Meltblown; and 3) chemical conversion of ion exchange group onto the grafted vinyl monomer. These steps are independently conducted in their suitable operation conditions. | 09-25-2008 |
20080271277 | Rubber product for wiping, rubber for wiper blade, method for producing rubber for wiper blade, and wiper unit - A rubber product for wiping, a rubber for a wiper blade, a method for producing a rubber for a wiper blade, and a wiper unit. The rubber product for wiping, for example, includes a hydrophilic gel-like surface treatment layer coated on at least a wiping surface of the rubber product, wherein the wiping surface is softer due to water absorption when moistened than when dried. | 11-06-2008 |
20100174062 | MODIFIED XANTHAN GUM, MODIFIED GUM ARABIC, AND MODIFIED TAMARIND SEED GUM, AND METHODS FOR CROSSLINKING XANTHAN GUM, GUM ARABIC, AND TAMARIND SEED GUM - An object is to provide a modified xanthan gum, a modified gum arabic, and a modified tamarind seed gum produced by crosslinking a naturally occurring polysaccharide such as xanthan gum, gum arabic, or tamarind seed gum, by irradiating them with radiation, and methods for crosslinking xanthan gum, gum arabic, and tamarind seed gum. | 07-08-2010 |
