In fact, for a long time, the difference between knitted denim yarn and woven denim yarn has not been clarified. At first, one thinks that it is dyed (knit denim yarn), and the other is the original color, which is not dyed (woven denim yarn, it can also be said It is a blank yarn). I have also checked it online for a long time. Basically, there is no such information. Some of them are just the contents of selling dog meat. Since you can't find ready-made materials, you can only organize and ask others.

The so-called knitted denim yarn is actually the yarn used to knit denim, and the woven denim yarn is the yarn used for woven denim (woven denim is the denim we usually see), currently knitted denim is mainly The clothes for women and children are basically not used for men's clothes. I only saw a men's knit jeans on the Internet.

The same point: before dyeing, knitted denim yarn and woven denim yarn are all ordinary cotton yarns (ie, blank yarns), which are the same in the production process.


difference:

1. The woven denim yarn has a higher twist than the knitted denim yarn. The practical layman means that the woven denim yarn is harder.

2. The uniformity of the knit denim yarn is higher than that of the woven denim yarn.

3. Knitted denim yarn has no sizing process, and woven denim yarn needs to be sizing. (A remarkable feature of denim is the warp sizing.) The sizing actually increases the hardness of the yarn, which in turn increases the hardness of the cloth, so there will be a desizing process behind.

4. Because the technical requirements of knitted denim yarns are generally higher than those of woven denim yarns, knitted denim yarns are also more expensive than woven denim yarns, and knitted denim fabrics are naturally more expensive than woven denim fabrics. This of course is also related to the equipment and difficulty in producing knitted denim. Knitting cowboys are new things compared to woven denim.


Knitting yarn requirements:

The yarn has a certain strength and extensibility so that it can be easily bent into a loop during weaving.

For short fiber spinning, the twist should be evener. The twist is too large, and it is easy to produce yarn kinks, which is easy to produce defects on the cloth surface.

The yarn is evenly dried and has less yarn defects. Uneven yarns tend to form shadows or clouds on the surface of the knitted fabric, and thick knots or details create defects on the fabric surface.

The surface of the yarn should be smooth, the friction coefficient is small, and the softness is good.

=============

Woven yarn requirements:

Weft requirements: The tension of the weft yarn during the weaving process is relatively small, and the requirements for the weft yarn are basically the same as those for the knitting yarn, that is, the elasticity and softness are required, and the twist is low.

Warp requirements: During the weaving process, the warp yarns are subjected to very high tension. Warp and sizing before weaving to give the yarn a better strength and a smooth appearance. The strength is large and the twist is large.

=============

There is still a big difference between the quality of the knitted fabric and the woven fabric. For example, in the twist of the yarn, the knitted yarn can not be higher than the woven fabric. Otherwise, the DEFECTS and the looms can be easily produced.
