Diagram showing S and Z twist. There are two common ways to ply a balanced yarn: regular and chain plying. Both methods involve the manipulation of "singles"—unplied strands on their own—into multiple-ply yarns by applying twist in the opposite direction than how the single was spun. For example, if in spinning the single the wheel was spinning clockwise (called a "Z" twist, as on any ...
Filling or weft yarns usually have fewer twists per inch because strength is not as important as with warp yarns, and highly twisted yarns are, in general, stronger. Warp yarns have to be stronger so that they can withstand the tension of the loom. Filament fibers, such as silk, or many synthetics, need only be twisted slightly to create a yarn.
Yarn is selected for different textiles based on the characteristics of the yarn fibres, such as warmth (wool), light weight (cotton or rayon), durability (nylon is added to sock yarn, for example), or softness (cashmere, alpaca). Yarn is composed of twisted strands of fiber, which are known as plies when grouped together. [19]
Thread is a fine type of yarn. thimble A thimble is a protective shield worn on the finger or thumb. third hand A third hand is a clamp that holds the fabric to be sewn. toile Toile is the British English term for a test garment. The equivalent American English term is muslin. trim
Persian yarn (also known as Persian wool) [2]: 26 is a loosely twisted 3-strand yarn of wool or acrylic, often used for needlepoint. Each individual strand is 2-ply; the yarn can be separated or combined as required. [2]: 26 Silk floss is available in two different types: flat, which has no twist, or only the slightest amount, [6] and twisted. [7]
Hanks, twisted and untwisted. The tie typically used to hold the coil together is visible on the left. The three uppermost yarns are in hanks. While hanks may differ by manufacturer and by product, a skein is usually considered 1/6th of a hank (either by weight or by length). One source identifies a skein of stranded cotton as being 8.25 yards ...
Spinning is a twisting technique to form yarn from fibers.The fiber intended is drawn out, twisted, and wound onto a bobbin.A few popular fibers that are spun into yarn other than cotton, which is the most popular, are viscose (the most common form of rayon), animal fibers such as wool, and synthetic polyester.

S-twisted and Z-plied yarns become excessively twisted when knitting in this technique, complicating the untwisting of the two strands of yarn. The excessive twist can cause the right side of the fabric to develop a horizontally ridged surface. Z-twisted and S-plied yarns will instead untwist when knitting in this technique.
