There should be no difference what so ever. Qiviut (pronounced KIV-EE-UTE) in the Yupik Eskimo language, means down or under wool. It refers to the winter coat of the Musk Ox. It covers their entire body closest to their skin in the fall and they shed it naturally every spring. Most of the qiviut in the world will come out Canada or Greenland, from culling the wild heards. Although you can get it from a couple of places in Alaska. I work for Oomingmak Musk Ox Producers Co-operative. Its a co-op of knitters that hand knit garments made from qiviut yarn.
difference between spun yarn and filament yarn
Yarn is fibre; bobbin is a storage reel for fibre.
Since neither word describes a natural fibre, the difference is probably vocabulary choice.
Textured yarn has for lack of better words a texture like confettie, eyelash, or fiber look to it. Micro yarn is very thin yarn.
Any fibre, regardless of the source -- natural or man-made, can be spun. Synthetic yarn contains no natural fibres.
Ring spun yarn is when the yarn is both twisted and wound at the same time. Open ended spun yarn is when the yarn is twisted by rotating at the hap or break in the flow.
If you mean 'weaving' . . . Spinning is making the raw material into yarn. Weaving is making the yarn into fabric.
Microfiber means the staple size in the yarn. Microdenier defines the polyester yarn lessthan 1 Denier
Poplin has a fine yarn with thicker yarn across it. Similar weight to Oxford. Twill has diagonal weave.
The main difference between polyester staple fiber yarn and polyester filament yarn is that polyester staple fiber yarn is made up of chemicals. Polyester filament yarn contains both man-made and natural fibers.
