Kärnspunna

Kärnspunna is a Swedish term that translates to "core-spun" in English. It refers to a type of yarn or thread construction where a central core, often made of a strong synthetic fiber like polyester, is wrapped or covered by staple fibers, such as cotton, wool, or a blend. This construction method aims to combine the desirable properties of both the core and the staple fibers.

The core provides strength, durability, and often a degree of stretch resistance, making the yarn suitable for applications where these characteristics are important. The outer wrapping of staple fibers imparts the aesthetic and tactile qualities typically associated with natural or blended yarns, such as softness, breathability, and a pleasant feel against the skin. Kärnspunna yarns can be produced in various combinations of core and covering materials to achieve specific performance and appearance requirements.

This type of yarn construction is commonly used in the textile industry for apparel, particularly for items like workwear, denim, and activewear, where enhanced durability and comfort are desired. It is also found in home furnishings, upholstery, and technical textiles. The specific properties of a kärnspunna yarn depend heavily on the materials chosen for the core and the staple fiber wrap, as well as the manufacturing process.
