Melt transcrystallization of polyethylene on high modulus polyethylene fibers
Journal of Applied Polymer Science, 1988AbstractA polytheylene composite was prepared and tested. It was consisted of a high‐density polyethylene (HDPE) matrix and uniaxial gel‐spun high‐modulus PE fiber. Aided by the similarity between matrix and fiber, transcrystallization of HDPE melt on the PE fiber surface was generated. Nucleating agents were not employed.

An Evaluation of Ultrastrong Polyethylene Fiber as an Ophthalmic Suture
Archives of Ophthalmology, 1985An ultrastrong polyethylene fiber was evaluated as an ophthalmic suture. Properties of this fiber and of nylon, polypropylene, and polyester sutures were measured by standard techniques for fiber testing and for testing knot characteristics of sutures. Their behavior in cataract and keratoplasty surgery was assessed qualitatively.

ABSTRACTThis contribution mainly studied the preparation of hyperbranched polyethylene (HBPE) fibers and HBPE/multiwalled carbon nanotube (MWCNT) composite fibers via electrospinning for the first time. Firstly, the effects of solvents, solution concentration, voltage, and rotating speed of collector on the morphology of HBPE fibers were studied. Among

Molecular models for creep in oriented polyethylene fibers
The Journal of Chemical Physics, 2020Highly oriented and crystalline polyetheylene (PE) fibers have a large failure stress under rapid tensile loading but exhibit significant creep at much smaller stresses that limits applications. A possible mechanism is slip of chains due to stress-enhanced, thermally activated nucleation of dislocations at chain ends in crystalline regions.

Polyethylene/keratin fiber composites with varying polyethylene crystallinity
Composites Part A: Applied Science and Manufacturing, 2005Short-fiber reinforced composites are made from keratin fibers obtained from poultry feathers and polyethylenes of varying crystallinity. The chemical nature of the polymer and fiber is kept constant and the molecular architecture of the polymer is varied.

Patterned Functional Carbon Fibers from Polyethylene
Advanced Materials, 2012Carbon fibers having unique morphologies, from hollow circular to gear-shaped, are produced from a novel melt-processable precursor and method. The resulting carbon fiber exhibits microstructural and topological properties that are dependent on processing conditions, rendering them highly amenable to myriad applications.

Characterization of Polyethylene in Film and Fiber
1987The range of polyethylenes, available to film producers, has been greatly increased with the large scale production of linear low density (LLDPE) polymers and the use of high density polyethylene (HDPE) in tubular film extrusion. These polymers are being used alone and in blends with high pressure low density polyethylenes (LDPE) in many film ...
