    摘要: TOWARDS THE SPINNING MASS AND THE MEAN FINENESS OF GRAIN OF WHICH INCREASES IN THE DIRECTION TO THE SPINNERET ACCORDING TO AN EXPONENTIAL FUNCTION.

    TO REMOVE IMPURITIES AND INHOMOGENEITIES FROM SPINNING MASSES OF FIBER- AND FILM-FORMING HIGH MOLECULAR WEIGHT POLYMERS THE MASSES ARE FILTERED THROUGH A FILTER PACK CONTAINING A FINELY DIVIDED MATERIAL WHICH IS INERT
