spandex 20d covered yarn 2075 polyester spandex covered yarn made in china free sample yarn

The spandex filament is led out from the core filament supply bobbin by the core filament input roller, and then passes through the hollow spindle. The hollow spindle rotates driven by the Dragon belt.The wrapped polyester filament wrapped on it is led out and twisted due to its rotation, and coated on the spandex core filament penetrated from the hollow spindle to form a polyester spandex covered yarn. The covered yarn is pulled and wound on the winding bobbin by the wire guide shaft.

3075 spandex covered yarn is an elastic composite yarn formed by taking spandex filament with a certain drafting multiple as the core and wrapping the polyester filament spirally outside the core filament through the covering process. The composite yarn not only has the characteristics of wrapped polyester, but also has the good elasticity and recovery performance of spandex, which makes up for the defect of single component filament.

The difference between mechanical and air covered yarns

(Use 2070 as an example to make it easier to understand.)

1) Output:

The daily output of 2070 machine-covered yarn is about 80kg, while the daily output of 2070 air-covered yarn is about 1700kg.

2) Raw materials:

The mechanical covered yarn is composed of DTY and spandex, while the air covered yarn is composed of POY and spandex.

3) Price:

The price of machine-covered yarn is approximately 1/3 higher than that of air-covered yarn.

4) Equipment:

The equipment for mechanical covering yarn is different from that for air covering yarn.

In addition to the above 4 points, there are differences in technology, parameters and so on.
