Concluding installment of a German article on artificial silk (rayon) manufacture. It describes reeling machines (Haspel) used to wind silk from spinning cakes into skeins, including a Carl Zangs A.-G. (Crefeld) reel with a patented counter, followed by washing, drying, chlorine bleaching, softening with paraffin or glycerin, and skein dyeing. It also compares magnified cross-sections of nitro, copper, acetate and viscose silk filaments at 230x, and notes how the shapes reflect the process used.
