Blown systems

One of the most recent developments in the use of polyolefin fibers is in composites of spunbond (SB) and melt-blown systems. Some examples of structures being made are SB/MB, known as SM, SB/MB/SB, or SMS, and other combinations of SB and MB. The... 

The Project Manager does not always have the time to prepare and implement a full-blown system. In these cases, the following empirical correlation developed by John Nabors from FMC Corp. can be used between 15 and 80% completion. ... 

Although Germany has a long-standing reputation as a passive welfare state with elaborate schemes of status-protecting income replacement through social insurance in case of unemployment and a full-blown system of active labour market policies, all benefit systems had formal elements of activation and work requirement - but they had not been enforced systematically. 

Inhalation by human beings of the glanders agent can lead to a full-blown, systemic blood infection (septicemia), severe pulmonary infection, and chronic inflammation of the skin and eyes. There is an incubation period from 10-14 days, and septicemia can lead to smallpox-like rashes on the skin. Even with antibiotic treatment, dissemination of B. mallei in an aerosol could result in high mortality among humans. 

Besides these general procedures, applied to the production of PO fibers before 1965, other modem ways have been developed and used for melt spinning. They include high and ultrahigh speed spinning, the split-film method, the spunbond process, and the melt-blown system. 

Compared with the spunbond process, the melt-blown system (spray method) produces microdenier (sprayed) fibers. Molten or dissolved fiber-forming PO polymers are forced with a spray gun or through a multiple-hole extruder to disrupt the filament into a high velocity hot air jet, to form superfine fibers less... 

The melt-blown process was developed in the 1950s and put to commercial use during the 1970s [163, 164, 166]. The initial patent design of Exxon [167] was executed later by the melt-blown plant system known as Automatie/Foume [168, 169] and by the Reicofil melt-blown system of Reifenhauser GmbH (Germany).
