Air Moistening in Woolen and Silk Mills
Air Moistening in Woolen and Silk Mills
Article · 2 pages
A two-page article by Robert Dantzer on controlling air humidity and temperature in woolen, worsted and silk mills. It covers how fibers absorb moisture, the effect of humidity on fiber strength and elasticity, and how static electricity is dispersed. It gives recommended temperatures and relative humidity for carding, combing, drawing, spinning, silk throwing, schappe (silk waste) work and weave rooms, and describes methods for neutralizing static electricity. The pages also carry short items on a cloth room daily report form, the Third International Cotton Conference, wool transport by motor, and paper cloth in Spain.
Artificial Silk in the Form of Loose Fibers
Artificial Silk in the Form of Loose Fibers
Article · 3 pages
A 1913 article, translated from the French, on making artificial silk (rayon) as short loose fibers rather than continuous filaments, so it can be carded and spun like wool, cotton or flax or blended with other fibers. It describes several patented processes: Bloch's cuprammonium (Schweitzer reagent) method, Girard's winding of viscose filaments on bobbins and cutting them into staple, Girard and Buffard's metal-plate spinnerets, and Cahen's collodion-based filaments formed without pressure. Line drawings show the machinery and spinneret details. The scan ends with a short unrelated note on depression in the Scotch tweed industry.
