Abstract: The process herein described provides the weaving of a manufactured product consisting of an upper fabric (2) made of cotton or any other suitable material and a lower fabric (3) with weft yarns (3a) made of wool and warp yarns (3b) interlaced with the weft yarns (2a) of the upper fabric (2). The weaving operation is followed by a printing step carried out on the upper fabric (2) of the manufactured product and by one or more teaseling steps on the lower fabric (3). Subsequent to each teaseling step there is a dimensional stabilization step of the manufactured product accomplished by a combined action consisting in moistening, heating and tensioning the product, the tensioning lasting until the end of the moistening and heating steps. A napping operation is also carried out together with the last teaseling step. By said process a blanket is obtained which comprises an upper fabric (2) with weft yarns (2a) interlaced with the warp yarns (3b) of a lower fabric (3).

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.
