Coathanger jet hotmelt unit for production of microfibers textile fleece has internal spacers set transverse to direction of hotmelt flow

摘要

A coathanger jet hotmelt unit forms microfibers for the production of textile fleece and has a line of jets (9) from a hotmelt inlet. The distributor block (1) passages incorporate one or more spacers that are transverse to the direction of hotmelt flow forming elongated, passive displacement plugs (12, 13) in defined positions. The displacement bodies are located at the center point of the passage and/or extend the entire length of the outlet slit where they act as static mixers. The displacement bodies are held in place by spacers formed by an etching process.
