### Yarns Tensile Test  
The results of the yarn's tensile test can be found in Tables 5 and 6, where the maximum load (\(\mathrm{F_{peak}}\)) and peak displacement of the extensometer (\(\mathrm{\delta_{peak}}\)) are detailed per specimen. Additionally, the maximum load, peak displacement of the extensometer, maximum strength (\(\mathrm{\sigma_{peak}}\)), strain at peak (\(\mathrm{\epsilon_{peak}}\)) and [PERSON]'s modulus (E) per case are detailed. Moreover, [PERSON]'s modulus was calculated using a linear regression of the \(\mathrm

The average curves were calculated as the average of the load per displacement.  
In order to continue with the experimental campaign, from the vegetal coatings that had two possibilities each, it was selected the one that showed the best performance on the yarns. Arabic gum without the ultrasounds because it decreased the maximum load, and in the case of colophony, dissolved in turpentine for cotton and dissolved in acetone for hemp yarns, as they were the ones that showed a higher maximum load.
