Embodiment Construction
[0006] Here, a fiber production method for twisted yarn with a linear density of 39.1tex is taken as an example. MMWPE resin (medium molecular weight polyethylene resin with a molecular weight of less than 1 million, the English name is Medium Molecular Weight Polyethylene, abbreviated as MMWPE), HDPE resin, nano SiO 2 , auxiliary agent, mixer, splitting machine, wire collecting machine, single-screw extruder and twice-drawing electric heating drawing machine; MMWPE resin (distributed by Zibo American Standard Polymer Fiber Co., Ltd.) has a melt index of 3.0g / 10min The molecular weight is 600,000-1 million. If the MMWPE resin is damp, it should be dried by wind, sun, and drying; HDPE resin (produced by Yangzi Petrochemical, the melt index should meet 0.6g / 10min-1.5g / 10min, The addition amount is 24.1‰-25.8‰ of the weight of the MMWPE resin. If the HDPE resin is damp, it should be dried by wind, sun, and drying; nano-SiO 2 (Commercially available nano-silica) is added in an am...
