Production manner of polypropylene monofilament, polypropylene monofilament and its application

摘要

The melt flow index of 2 - 16g/10 minute (MFI) it consists of the polypropylene which it possesses with 230C/2.16kg, being the manner which produces the polypropylene monofilament which had the diameter above 0.050mm and the abrasion resistance which is improved, the extruder being high-level, 20 - 0.01 weight % the additive is added by the polypropylene, melting ones the spinning are done while bathing and stretching are done in the monofilament, feature that this monofilament is retracted. The melt flow index of 2 - 16g/10 minute (MFI) it consists of the polypropylene which it possesses with 230C/2.16kg, the polypropylene monofilament which had the diameter above 0.050mm and the abrasion resistance which is improved has the strength of 50cN/tex at least the extension which is suitable to the largest stretch stress under 30% (the break dot to extend) concerning. In addition, any this things after 24 hours treating with wear rate and the 120C under 0.05%, have relative fragmentation energy 100%.
