Gummituch

Gummituch is a term used for rubberized fabric, a textile that has been coated or impregnated with rubber to become waterproof. The concept originated in German-speaking regions and has historically described fabrics prepared for outdoor and weatherproof use.

Production and materials are based on a base textile such as cotton, linen, or later synthetic fibers, which is coated on one or both sides with natural rubber latex or with synthetic rubbers. The coating can be applied by dipping, brushing, or calendering, and the resulting material varies in thickness and flexibility. The choice of rubber, the fabric weight, and the coating method determine the material’s waterproofness, durability, and possibly its breathability.

Properties of Gummituch typically include water resistance and a high level of durability, combined with flexibility for wear or use in coverings. However, rubber coatings are generally not highly breathable and may become stiff, crack, or degrade with heat, ozone, or aging. Proper care involves avoiding high temperatures and harsh solvents, and inspecting for cracks or delamination over time.

Historically, Gummituch found broad application in waterproof clothing such as raincoats and mackintoshes, as well as in tents, covers, awnings, and other outdoor equipment. In the latter half of the 20th century, many uses were gradually replaced by laminated or coated fabrics made from polyurethane or PVC, which offered improved performance and longevity.

Today, rubberized fabrics are produced for niche or restoration purposes and in some regions remain part of traditional or specialty textile traditions. Modern equivalents in waterproof textiles often rely on synthetic coatings rather than natural rubber.
