It&#039;s for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>keep the yarn stable<\/strong>, reduces breakage\/corrosion when pulled<\/li>\n\n\n\n<li><strong>Adjust the uniformity by feel and skill.<\/strong>, something the machine doesn&#039;t have<\/li>\n\n\n\n<li><strong>reduce friction<\/strong>Avoid creating fibrous strands in the first place.<\/li>\n<\/ul>\n\n\n\n<p>Most importantly: this type of hand-spun yarn <strong>Not suitable for machine-line weaving.<\/strong> like many industrial fiber lines. <strong>The machine can weave fabric evenly and beautifully.<\/strong>, But <strong>This hand-spun fabric does not meet the proper &quot;yarn properties&quot; standards.<\/strong> (especially when the goal is to preserve the natural, airy, and authentic feel of the raw silk).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Why is 90 days still needed?<\/h2>\n\n\n\n<p>90 days is not 90 days of &quot;continuous work&quot;.
