Experimental production of roofing felts
Description of investigation being conducted at Bureau to determine relative value of different fiber compositions in life and serviceability of asphalt saturated and coated roofing felts; experimental felts tested were composed of varying proportions of usual felt-making fibrous materials, and with high content of low-grade substitutes not employed commercially in roofing felts; relatively large amounts of substitute materials can be used in admixture with rag stock. (see also Paper Trade Jl., vol. 89, no. 9, Aug. 1929, pp. 44-48)
