Abstract

The invention provides a plant-derived PE masterbatch. The plant-derived PE masterbatch is mainly prepared by blending and fusing a PE masterbatch and a modified motherwort extract, wherein a mass ratio of the PE masterbatch to the modified motherwort extract is 99: 21. The invention also provides a preparation method for the above cellulosic fiber. The plant-derived PE masterbatch prepared in theinvention is regular in shape and free of connected granules and chippings and has particle size uniformity of 93.2-94.9%, melt flow rate of 4.4-4.8 g / 10min and tensile modulus of 284-291 N / mm<2>; and a prepared fiber has breaking tenacity of 58.6-59.2 cN / dtex, elongation of 9.0-9.4% and a wear resistance level of level 4.

Description

technical field [0001] The invention relates to a plant-derived PE masterbatch and a preparation method thereof, belonging to the field of fiber masterbatch preparation. Background technique [0002] PE masterbatch refers to the basic pellets for making PE fiber, which is an important variety of synthetic fibers. Polyethylene (PE for short) is a thermoplastic resin obtained by polymerizing ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can resist most acids and alkalis (not resistant to acids with oxidizing properties). Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. [0003] Plants in nature, such as wormwood, Folium chinensis, mint, motherwort, etc., are widely welcomed by technical enthusiasts in the fiber field due to their own unique charact...
