Abstract
The invention relates to a protective cover of fibre material such as non-woven material, intended to be applied as a cover on a substructure such as those intended for sitting or lying, for example as an antimacassar for seats, there being at least one row of stitching running across the cover and made as double chain stitching with such thread structures that it forms an attachment for the hooks of a burr strip attached to the substructure. The upper thread of the double chain stitching consists of a relatively highly elastic thread of multifilament type having crimped filaments, the upper thread forming consecutive loops on the lower side of the cover in a known way, while the lower thread of the double chain stitching consists of a cotton or cotton-synthetic thread which is relatively unelastic in relation to the upper thread. Further, the tension in the upper thread is less than the tension in the lower thread so that the upper thread assumes its fluffy and voluminous condition to thereby form an easily entanglable fastening for the hooks of the burr strip.
