Sammenfiltret

Sammenfiltret is a Danish term used in textile arts to describe material in which fibers have been densely matted and bonded into a single, cohesive fabric or surface. The key idea is that individual fibers or pieces of felt have been joined so that they form a unified whole, without visible seams between parts.

The term can refer to both a process and the resulting material. It is commonly achieved through wet felting, where wool fibers are layered, wetted with warm soapy water, and agitated until interlocking occurs, and through needle felting, in which barbed needles are repeatedly inserted to tangle the fibers. It can also describe the fusion of already-cut felt pieces to create a continuous surface.

Sammenfiltret fabrics are nonwoven and can range in thickness from light to very dense. They tend to be sturdy, warm, and resistant to fraying, though they can shrink or felt further with heat and agitation.

Applications include garments, accessories, art objects, and decorative textiles, as well as upholstery panels in crafts and design contexts. Care typically involves gentle washing in cool water or dry cleaning, with careful drying to avoid distortion.

Etymology: sam­menfiltret is a compound of sam­men (together) and filtret (felted), describing the bonding of fibers by felting. In English-language textile discourse, it is often translated as "felted together" or "joined by felting."
