Abstract
The process for the manufacture of a wool fabric to be used as a mattress cover comprises four steps in succession, that is a loosening step, a shearing step, a moistening step and a pressing step, and further trimming steps for applying elements of electrically conductive material to said fabric as well as at least a shunt for grounding the same elements. The wool fabric 16 thus obtained comprises wool yarns having a substantially reduced length and sticking fast to the weft of the fabric itself, as well as elements 104, 106 of electrically conductive material and at least a shunt 108 for grounding the elements 104, 106 and adapted to allow the electrostatic energy to be discharged from a sleeping person.
Claims14
A process of manufacturing a wool fabric capable of withstanding rubbing stresses and wear and eliminating electrostatic charges wherein a raw wool fabric is subjected to a loosening step during which wool flock is pulled out from the fabric and given a uniform direction;
- the loosened fabric is subjected to a shearing step to clip the previously raised flock;
- the sheared fabric is subjected to a moistening step and the moistened fabric is subjected to a pressing step to enhance uniform adhesion of flock to the fabric weft;
- and said pressed fabric is subjected to further trimming steps to apply electrically conductive elements thereto as well as a shunt for grounding said elements.
