The study of tin-weighted and unweighted samples of silk after various treatments and exposures to sunlight and storage at standard conditions (of 65 per cent relative humidity at 70 degrees F. temperature) permits the following conclusions: (1) No deterioration results from exposures to standard atmospheric conditions over a period of two and one-half months even when acid or alkaline perspirations are applied. (2) Sunlight exposure causes a marked deterioration in both unweighted (but dyed) and tin-weighted silks, the loss in strength in 100 hours exposure amounting to about 25 per cent for unweighted and about 50 to 75 per cent for weighted silks. (3) Acid and alkaline perspiration treatments increase the deterioration when sunlight exposures are given, so that the loss in strength in 100 hours' exposure is about 35 per cent for unweighted and about 65 to 100 per cent for weighted silk. (4) Dry-cleaning solvents in no case caused any appreciable deterioration of the silk fabrics.

Excerpt from Effect of Dry Cleaning on Silks: A Comparison of the Effect of Dry Cleaning and Some Service Conditions on the Strength of Silk The silk fiber just as received from the cocoon has an almost trans parent outer covering called sericin, which renders it harsh to the feel, stiff, coarse, and lusterless. This coating is permitted to remain through the reeling and throwing processes; thus it is a part of the raw silk of commerce as received by the manufacturer.

In 1901 the National Bureau of Standards (NBS) was founded to provide standard weights and measures and to be the national physical laboratory for the United States of America. The NBS conducted a lot of research in the fields of science and technology which were reported as "Technological Papers." In 1988 the NBS became what we know now; the National Institute of Standards and Technology (NIST). This is one of those documents written by employees of the NBS.
