摘要： Provided are bicomponent fibers with improved curvature. The bicomponent fiber comprises a first region and a second region. The first region comprises a first polyethylene composition and second region comprises a second polyethylene composition, wherein the first polyethylene composition has a crystallization temperature (Tc) greater than a crystallization temperature (Tc) of the second polyethylene composition. The bicomponent fiber can be used to form a nonwoven.

摘要： A process for producing an ethylene-based polymer com prises polymerizing, by the presence of at least one free-radical initiator and using a high pressure tubular polymerization process, a reaction mixture containing ethylene and at least one CTA system comprising one or more CTA components to produce the ethylene-based polymer. The free-radical initiator is dissolved in a solvent com prising a saturated hydrocarbon to form an initiator solution which is added to the polymerization using an initiator feed line to an initiator injection pump. At least 50 wt% of the solvent has i) a dry point of less than or equal to 160°C and ii) an initial boiling point of greater than or equal to 100°C. The polymerization process has a ratio of in let pressure to first peak temperature of less than or equal to 9 Bar/°C. At least one CTA make-up stream is fed into the polymerization process, wherein less than or equal to 30 wt% of the at least one CTA make-up stream comprises one or more saturated hydrocarbon CTA(s) with a maximum carbon atom number of 6 per molecule.
