Diolen

Diolen is a historic trade name used for polyamide (nylon) fibers marketed by various chemical and textile companies in the mid-20th century. The term did not refer to a single, fixed formulation; instead, it encompassed a family of nylon fibers produced under the Diolen brand by different manufacturers. As a result, the exact polymer composition could vary, but the fibers were typically aimed at providing the strength and versatility associated with nylon polyamides.

Manufacture and properties

Diolen fibers were produced by standard nylon extrusion and drawing processes, yielding filaments suitable for fabric production. Like other nylon fibers, Diolen offered high tensile strength, good elasticity, abrasion resistance, and heat tolerance for a synthetic textile. The fibers dyed well with typical nylon dyes and were used across a range of end-uses. They could be formulated into staple fibers or continuous filaments depending on the application.

Applications

Diolen found use in hosiery, lingerie, swimwear, as well as upholstery, carpets, and various industrial or technical fabrics. The brand was part of the broader shift in the mid-20th century from natural fibers to synthetic polyamides for both consumer and technical textiles.

History and legacy

Diolen gained prominence in Europe during the 1950s and 1960s as nylon fibers expanded in popularity. Over time, as newer nylons and competing synthetic fibers emerged and branding evolved, the specific use of the Diolen designation diminished. Today, references to Diolen are largely historical, although vintage fabrics or products may still bear the name.
