PROCESS FOR IMPROVING ELECTROSTATIC CHARGING OF FLEXIFILAMENTS |
摘要 |
The efficiency of electrostatic charging of polyolefin web in a process for flash-spinning polyolefin plexifilament from solution in a C4-C7 hydrocarbon, forming the plexifilament into a web, electrostatically charging the web, and laying the web down as a sheet is improved by having present in the electrostatic charging step environment a charge-improving compound, which can be any one of a number of specifically identified classes of charge-improving compounds. The charge improving compounds are present in an amount of at least 0.1 ppm of the atmosphere in that environment or more.
