To be precise, Dyneema is a whole family of fabrics based on fibers obtained from ultra-high molecular weight and high-density polyethylene. There are twisted strands that weaved and formed a woven fabric. They can also be simply fused into a layer of polymer of the desired shape, for example, in the production of chains or armor plates. Finally, often the fibers are thermally glued into a non-uniform cloth, which is laminated on both sides with transparent synthetic films – this group of materials is most interesting and is known as Dyneema Composite Fabrics. They are 4 times lighter and durable than the famous Kevlar and 15 times stronger than steel wire of a similar section. This allows you to create a very light and compact package of things without losing their strength and durability. The first samples of fibers were received in 1963, but their commercial use began only 27 years later.
Dyneema fabric used in making sails for sea yachts, body armor and armor plates, jackets, chains and ropes for loading operations, rucksacks, slings for mountaineering, tents, ultra-lightweight tents, and shelters. The advantages of the fibers include their chemical inertness, resistance to ultraviolet radiation, zero elongation of the fibers under tension, and extremely low wettability with water. Dyneema is not at all inclined to absorb and retain moisture, so it practically does not require the application of water-repellent treatment. Laminated fabrics are completely waterproof, making them ideal for ultralight Hiking tents, backpacks, and almost weightless waterproof clothing.
The UHMWPE solution is formed into fluid filaments by spinning said solution through a spinneret containing multiple spinholes. The term "fluid filament" refers to a fluid-like filament containing a solution of UHMWPE in the solvent used to prepare said UHMWPE solution, said fluid filament being obtained by extruding the UHMWPE solution through the spinneret, the concentration of the UHMWPE in the extruded fluid filaments being the same or about the same with the concentration of the UHMWPE solution before extrusion.
