1, the first thing that will come to mind is "the thickness of this yarn"

Our common method of indicating the thickness of the yarn is the number, number or denier, and the short fiber yarn is generally expressed by the number of British counts. Filament is generally expressed by Daniel number, such as: pure cotton 32 pieces written: C32S, the conversion factor of the number and number is 590.5. Polyester 150 Denier writing: T150D.

2, and then ask "The shape of this yarn"

Is the state of single yarn or strand, strand is double or three or even more strands, or slub yarn and so on. For example, C32S/1 indicates 32 yarn strands, and C32S/2 indicates 32 yarn strands. The number system is C14.8×2, indicating 40 British double yarn.

3. Again, "What is the spinning process of this yarn?"

Is it spinning cup spinning (air spinning)? Vortex spinning? Ring spinning Combing? Half combed?) Siro spinning? Tight spinning? Or filament or stretch silk and so on.

4, and "This yarn twist direction, twist"

The twist direction is divided into positive twist (Z twist) and reverse twist (S twist), usually the single yarn is positive twist, the strand is reverse twist, of course, according to demand.

5. "What is the composition of this yarn and its moisture recovery?"

Components are divided into natural fibers and chemical fibers, natural fibers include: cotton, linen, silk, wool; Chemical fibers are divided into artificial fibers and synthetic fibers, synthetic fibers include polyester, nylon, acrylic, polypropylene, chlorinated fiber, etc., artificial fibers include regenerated cellulose fibers, such as viscose, modal, Lycel and so on.

Each fiber corresponds to a different moisture recovery rate, such as cotton fiber is 8.5%, polyester fiber is 0.4%, viscose fiber is 13%.

6, finally, is "the strength of the yarn, three sections and other physical indicators and appearance indicators"

Physical indicators include yarn strength, strength uneven, weight uneven, dry, yarn defects and so on can meet the requirements of the variety, appearance indicators including hair and so on.
