Melt-blowing is an industrial method for the rapid production of nonwoven fibres In melt-blowing a polymer is melted and extruded through a capillary while heated air is blown through an air nozzle The aerodynamic drag of the air jets on the polymer provides the attenuation force that draws the polymer streams into fine diameter fibres In this paper the following factors are presented: a Patent application title: NONWOVEN TISSUE SCAFFOLD Inventors: Stephanie M Kladakis (Watertown MA US) Joseph J Hammer (Bridgewater NJ US) Shetty Dhanuraj (Somerset NJ US) Sridevi Dhanaraj (Raritan NJ US) Mark Timmer (Jersey City NJ US) Assignees: DEPUY MITEK INC IPC8 Class: AA61F208FI USPC Class: 623 1412 Class name: Prosthesis (i e artificial body members) parts

In other cases the melt-blown batt may be laminated to another nonwoven especially a spun-laid one or the melt-blown batt itself may be bonded but the method must be chosen carefully to avoid spoiling the openness of the very fine fibres In the bonded or laminated form the fabric can be used for breathable protective clothing in hospitals agriculture and industry as battery separators

The present invention provides bi-component polymeric macrofibers having an ethylene-vinyl alcohol (EVOH) outer component and a core or second component comprising a polymer blend of polypropylene grafted with maleic anhydride and polypropylene or polyethylene The bi-component polymeric macrofibers provide excellent fiber reinforcement in concrete applications

The melt blown process is a nonwoven manufacturing system involving direct conversion of a polymer into continuous filaments integrated with the conversion of the filaments into a random laid nonwoven fabric First developments in this field of technology in the industrial area started around 1945 The general process description is similar to the spunlaid process but in detail both types

Potassium permanganate is dissolved in water and the clean air is blown to open Shower water is further treated with mild quantities of neutralizer before adding to main drain But where the potassium permanganate spray is used in low concentrations then there is now need to treat shower water This mild potassium permanganate mixed water is rather useful for water reservoirs to keep the

History Production of ultra-fine fibers (finer than 0 7 denier) dates back to the late 1950s using melt-blown spinning and flash spinning techniques However only fine staples of random length could be manufactured and very few applications could be found Experiments to produce ultra-fine fibers of a continuous filament type were made subsequently the most promising of which were run in

Melt-blown nonwoven fiber diameter in particular because of its small size the pore size is tiny As high rate of meltblown fabric with holes and characteristics of large specific surface area melt-blown nonwoven with excellent oil- absorbent property The test result told us it can absorb more than 17-20 times of their own weight of oil According to this feature it can be made as suction

Another important growth market for Freudenberg is Evolon its microfilament nonwoven material which was developed more than a decade ago but continues to evolve "Thanks to microfilaments which are around 100 times thinner than a human hair Evolon's worldwide patented technology provides outstanding lint-free anti-scratch cleaning performance " Olson says

The most commonly used fabric forming methods are weaving braiding knitting tufting and nonwoven manufacturing Figure 1 2 shows the schematics of fabrics produced by these methods Weaving is the interlacing of warp and filling yarns perpendicular to each other There are practically an endless number of ways of interlacing warp and filling yarns Each different way results in a different
