A short July 2020 Ars Technica article, "120,000-year-old necklace tells of the origin of string", linked below.

Based on the age of the artifacts, and the findings, the implication here is that "string technology" and use may have had its origins in jewelry making:

"If you’re not an archaeologist, dating the invention of string might sound esoteric. But twisting plant or animal fibers into thread is the key to a lot of other technologies, from clothes to seafaring."

Also:

"It’s going to take more evidence to unravel the origins of string and all the technologies that tie into it. But Bar-Yosef Mayer is optimistic. 'It is only in the last decade or so that we started finding these finds, due to increased use of microscopy in archaeological research,' she told Ars."
