Knit fabric is one of the most common types of fabric used for clothing. In knitting, thread is twisted into loops which are then interwoven with other loops to make a sheet of fabric.Several different types of knitting fabrics exist and each of them is distinguished by its appearance and function. The most common are the following:
Weft knitted fabrics, e.g., jerseys and cardigans, are knitted with yarn held in the loops of each course; a weft insertion fabric is made in the same way, except that an additional yarn is placed in each strand. This inserted yarn can be decorative or functional and provides stability, comfort, and cover.Warp knitted fabrics, e.g., sweaters, are knitted with threads held in the loops of each course; warp lace, entrelac, and rib fabrics are made in the same way, except that each strand is tied to the next strand by a single loop. The woven surface of the fabric has a three-dimensional effect, like lace, which can be achieved by varying the number and type of stitches.
In general, knit fabrics are incredibly stretchy, and can easily elongate up to two times their length and width. This is because the loops that form the fabric are elastic. Woven fabrics, on the other hand, cannot be stretched as far because they need to fold in order to conform to a complex shape. Moreover, knit fabrics are wrinkle-resistant because they have an excellent elasticity.
