Is there a way to unspin yarn?
Yes 1With fingers separate the individual fibers that create the yarn, Attach each to a spool or spindleAttach these spools to a turn table, In the center of the turntable attach one wire for each thread with a spiral loop at the unattached endThis loop is like the spiral ones on sewing machines- you just slide the thread inSpin turntable slowly in the direction opposite the way the yarn was spunfeeding the yarn onto the spools2 Separate a length of thread from the yarn by hand, wind it onto a spoolRepeat for each additional strandTHis is what embroiderers do to strip 6ply embroidery floss to the number of stands needed for the project3If all you need is loose fibers for scrim? cut the yarn into short pieces, Gently rub to separate Methods 1 and 2 work best with smooth yarnsMohair or nubby yarns require geometrically greater patience and the willingness to splice the result if longer lengths are needed as breakage occurs more with these yarns.
Any makeshift bag that you put it in will probably void your warranty from dellJust go down to your local computer shop and ask if you can have oneThey will have plenty.
