A spool of 30/3 thread has a single's equivalent of 10, because a single strand or ply of that thread has a cotton count size of 10. A 20/2 spool has the same single's equivalent as a 30/3, but a 30/2 spool has a single's equivalent of 15, which means it is composed of individually heavier plies than a 30/3.
Spool knitting is a form of circular knitting using pegs rather than needles, one peg per stitch. A variant automates the stitching action, thus producing a hand-crank circular knitting machine. Commercial knitting machines are heavy-duty powered versions of the hand-cranked ones; they may knit multiple threads at once, for speed.
Many things can be made from the resulting tube. For example, it can be wound in a spiral to produce a mat or rug or, if a larger spool with more nails is used, a sock or a hat could be made. Historically, spool knitting has been used to make horse reins. [1] Spool knitting is a traditional way to teach children the basic principles of knitting.

A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. [1] Bobbins are typically found in industrial textile machinery , [ 2 ] as well as in sewing machines , fishing reels , tape measures , film rolls , cassette tapes , within electronic and electrical equipment, and for various ...
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. [1] Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in ...
There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely used in filament 3D printers is the direct-drive extruder, which sits closer to the extruder hot end.
In 1700, the Italians were the most technologically advanced throwsters in Europe and had developed two machines capable of winding the silk onto bobbins while putting a twist in the thread. They called the throwing machine, a filatoio, and called the doubler, a torcitoio. There is an illustration of a circular hand-powered throwing machine ...
