Summary:

Types of long-fiber yarns:

• Compound yarn:

Compound yarn, the core of synthetic long and short fibers is used, and the core wire is coated with natural, artificial long and short fiber as the hard yarn, which can be blended with long and short fibers. This process can improve the wearing performance of the silk fabric - it is not resistant to wrinkles and washing must be ironed It can be worn when it is hot, and when it is processed, because the staple fiber is easy to be produced by cotton wool, it is necessary to pay attention to the neatness of the machine, otherwise it may cause bad yarn formation.

Uses as follows: plain weave, flat knitting machine, circular knitting machine.

• Twisted yarn:

Twisted yarn is an extended elastic fiber or hard yarn, together with one or two different types of hard yarns, can be simultaneously woven and twisted, so that the fabric can have different fiber characteristics at the same time, so that the fabric performs better than a single fiber. In the process of merging, it is necessary to pay attention to whether the quality of each yarn is similar, otherwise it is easy to cause poor processing, and the fabric surface is not flat.

Uses as follows: woven fabric, flat knitting machine, circular knitting machine.

• Draw Textured Yarn:

Draw textured yarn is made of (polyester pre-oriented yarn=POY) as the original yarn, and is processed by stretching and false twisting. There is often a certain degree of flexibility and contraction.
POY is made into DTY= Polyester Draw Textured Yarn.
