First of all, we have to distinguish the difference between knitting and woven. The most obvious difference between woven and knitted is that woven is made by interweaving warp and weft. Therefore, there are two directions: longitude and latitude. Knitting is made up of loops that are continuously knotted, so it has a certain degree of elasticity. As for the feel, it is affected by a series of factors such as yarn count, weaving method, and finishing. But usually knitted fabrics feel softer. For example, the underwear and sweaters we wear are all representatives of knitted fabrics. The suits, shirts, and jeans we wear are all woven fabrics. Summer tops, except shirts and chiffon
, basically mostly knitted T-shirts, and woven ones are generally used for jackets, shirts, and trousers.
Knitting yarn requirements
01
Yarn has a certain strength and extensibility so that it can be easily bent into coils during the weaving process.
02
Short When fiber is spun, the twist should be uniform and smaller. The twist is too large, which can easily cause yarn kinks and defects on the cloth surface.
03
Yar The lines are dry evenly and there are few yarn defects. Uneven yarns can easily form shadows or clouds, thick spots or details on the knitted fabric surface, resulting in defects on the fabric surface.
04
Yar The thread surface should be smooth, with a small friction coefficient and good softness.
Yarn requirements for woven fabrics
01
Weft requirements: The tension that the weft bears during the weaving process is relatively small, and the requirements for the weft are different from those of knitting The yarn used is basically the same, that is, it must have a certain degree of elasticity and softness, and the twist must be low.
02
Warp Requirements: During the weaving process, the warp yarns are subjected to very high tension. The yarn must be warped and sized before weaving to give the yarn better strength and a smooth appearance. High strength and high twist.
01
Same Point
Before dyeing, knitted denim yarn and woven denim yarn are actually ordinary cotton yarn (i.e. gray yarn). The production process is the same.
02
Different Point
Woven denim yarn has a higher twist than knitted denim yarn. In fact, in layman’s terms, it means that woven denim yarn is stiffer.
The evenness requirements of knitted denim yarn are higher than those of woven denim yarn.
Knitted denim yarn does not have a sizing process, while woven denim yarn requires sizing. (A distinctive feature of denim is warp sizing and dyeing) Sizing will actually increase the hardness of the yarn, which in turn increases the hardness of the cloth, so there will be a desizing process later.
Because the process requirements of knitted denim yarn are usually higher than those of woven denim yarn, knitted denim yarn is also better than woven denim yarn Yarn is expensive, and knitted denim fabrics are naturally more expensive than woven denim fabrics. This is of course also related to the equipment and difficulty of producing knitted denim. After all, knitted denim is a new thing compared to woven denim.
