Polyethylene resin for figured island fiber heat-bonded non-woven fabric as well as preparation method and application of polyethylene resin

Abstract

The invention belongs to the technical field of high polymer materials, and discloses polyethylene resin for figured island fiber heat bonding non-woven fabric as well as a preparation method and application of the polyethylene resin. The polyethylene resin is prepared by adopting a tubular high-pressure polymerization process, the density of the polyethylene resin is 0.920-0.926 g / cm < 3 >, the melt flow rate is 15-40g / 10min, the molecular weight distribution value is 3-7, the branched chain content is less than or equal to 11.7 / 1000C, and the content of long branched chains with the branched chain length of 6C or more is less than or equal to 2.2 / 1000C. The polyethylene resin is narrow in molecular weight distribution, low in branched chain content, good in island phase fluidity matching performance, good in spinnability during composite spinning, good in figured island fiber uniformity and stability and high in fiber web heat bonding fastness, and can be applied to composite spinning figured island fibers and heat bonding non-woven fabrics thereof.
