Description

A manufactured fiber made from the polymers or copolymers of ethylene. Ethylene was first polymerized in 1933 by ICI in England. In 1954, Karl Ziegler developed a process for higher weight polyethylene that allowed it to be spun into fibers. These fibers, from high density polyethylene, are lightweight, smooth and white with a slightly waxy feel. They are resistant to wear, creases, acids, alkalis, moisture, fungi and insects. Polyethylene fibers do not accept dyes, so they are colored by mixing pigments in the molten polymer prior to extrusion. The fibers slowly degrade in sunlight and can be stained by oils. Polyethylene fibers are used to make waterproof paper (Tyvek®), ropes and fabrics for upholstery for industrial and outdoor applications.

Other Properties

Soluble in perchloroethylene (do not dry-clean) and most chlorinated and aromatic solvents when gently heated. Resistant to strong acids, alkalis, bleaches. Cross sections = circular or elliptical.

For HDPE fibers: Tenacity = 5.0-8.0 g/denier; Moisture regain =

Melting Point 130-138
Density 0.95-0.96
Refractive Index 1.52
Spectra 900

Hazards and Safety

Burns with a heavy, sooty, waxy smoke. Degraded by ultraviolet light and sulfur containing pollutants. May contain additives ( such as antioxidant BHT) that can migrate and cause staining.
