Since the turn of the century, artificial silk was increasingly in competition with silk, making it necessary to develop new quality testing methods. After the end of the Second World War, the Zurich Silk
Conditioning Institute managed to remain profitable by including other yarns in their testing

At the beginning of the 1960s, the Zurich Silk
Conditioning Institute faced numerous restructuring processes. A new administrative board decided that the Zurich Silk Association (ZSIG) should have a textile testing institute, and a large package of shares was transferred to the ZSIG, which thus

277:
From the mid-1990s, testing focused less on the textile itself, but rather on the conditions under which the textile was produced. The “Öko-Tex
Standard 1000”, which was introduced in 1995, incorporated additional parameters into the assessment.
246:
The recession of the 1920 affected the institute, however, after the post-war recession had been overcome, the second half of the decade was a period of prosperity. In 1932, the Zurich Silk
Conditioning Institute moved to Gotthardstrasse 61.

On 1 July 1847, the Silk
Conditioning Institute started its operations. In addition to silk, the institute also started to determine the commercial weight for the Basel ribbon industry.
