Method to separate polypropylene in the processing of silk schappe, whereby a lap (14) of silk fibers which are partly combed or are at least made sufficiently parallel undergoes an action of heating between 110.degree. C. and 160.degree. C. together with a simultaneous action of controlled compression so as to form clusters of polypropylene and silk fibers and thereafter an action of combing or pre-combing for the definitive removal of those clusters of polypropylene and silk fibers. Device to separate polypropylene in the processing of silk schappe, which is positioned downstream of a drawing frame (13) or analogous machine producing a lap (14) of silk fibers, the device including a conveyor means (belt/drum) cooperating with means that heat and apply adjustable pressure to the lap (14).
A method to separate polypropylene impurity fibres in the processing of silk schappe, comprising providing a lap of sufficiently parallel silk fibres, heating said lap between 110.degree. C. and 160.degree. C. compressing said lap so as to form clusters of polypropylene and silk fibre and thereafter combing or pre-combing the lap for removal of said clusters of polypropylene and silk fibres.
A separator device to separate polypropylene impurity fibres in the processing of silk schappe, which is positioned downstream of a machine producing a lap of silk fibres, said separator device comprising a conveyor means and pressure means for heating and applying adjustable pressure to the lap being conveyed by said conveyor means.
A plant for the treatment of silk schappe, comprising:
