best selling socks knitted with high-quality 3075 spandex covered 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.

3.Q :What is covered yarn?

A :Covered yarn is a type of combination yarn. It uses a filament as the core, and another fiber wrapped around it in a one-way spiral.

4.Q :What are the characteristics of spandex covered yarns?

A :Air covered yarn (ACY for short) is a kind of yarn which is drawn by filament and spandex at the same time through a certain type of nozzle and regularly sprayed by high compressed air to form rhythmic network points.The fabric feels soft and smooth; Mechanically covered yarns (SCY for short) are spun and twisted on the core spandex with uniform draft. They are twisted and twisted (abbreviated as TPM). The main feature of this yarn is its smooth and straight fabric style.

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.
