The air covering machine has the following functions: it feeds continuous fibers such as polyurethane yarn, generally known as spandex, nylon and polyester, into an interlacing nozzle with a feed roller set at arbitrary speed, interlaces that yarn with air using turbulence generated by compressed air inside the nozzle, and then produces yarn known as Air-Coated Yarn ACY.

Air-Coated Yarn (abbreviated as empty bag, abbreviated as ACY in English) is a yarn that is formed by a pair of nozzles and a spandex yarn through a certain type of nozzle, which is formed by a high-compression air jet to form a rhythmic network point. . The fabric feels soft and smooth; the mechanical covering yarn (referred to as the machine package, abbreviated as SCY) is to continuously rotate the outer fiber filament and wrap it on the core silk spandex which is uniformly drawn, which is twisted and twisted. (English abbreviation for TPM), the fabric style is flat and its main features.

The machine starts slowly with inverter, stable performance, easy operation. Individual spindle control, set length stop. When the yarn is full on the bobbin or yarn broken, the spindle will stop automatically.

It’s a highly cost effective machine ( small investment, large capacity, convenient production and different spindle can produce different yarn size). The final product suits for the seamless underwear, socks, gloves and so on.

Machine can be used to make for the FDY intermingle point. (option)

Features: Each Spindle with Air Jet, Individual Oiling System, Yarn Sensor Device and Tensioner.

Air-covered yarn (ACY) is a yarn in which the outer fiber filament and spandex yarn are drawn through a certain type of nozzle at the same time, and the rhythmic network point is formed by the regular spray pressure of high-compressed air.

When you are delving in the production of yarn, you will realize that different materials have different requirements for production. To efficiently produce thread for spandex, polyester, nylon, and lycra; investing in a quality classic Air Jet Covering Machine is imperative.

In the spinning process, the spandex stretch is an important process parameter, which affects the coverage of the covered yarn and the elasticity of the fabric, and affects the elongation of the covered yarn. Uniformity and creep properties. The pre-draw ratio of spandex is too small, and the advantage of elasticity of elastic fabric can not be fully utilized. When the drafting is too high, the spinning is difficult, and the yarn breaks easily, and the product quality decreases. In addition, the percentage of spandex yarn also affects. The covered yarn has high elasticity, high content and good elasticity. In the case of a certain size of the spandex yarn, the draw ratio is increased, and the percentage of the spandex yarn is lowered, that is, the pre-draw ratio of the spandex is inversely proportional to the percentage of the spandex.

The tensile strength of the covered yarn increases with the increase of the pre-draw ratio of the spandex. After the drafting reaches a certain value, the shrinkage of the spandex yarn causes the outer fiber to be curled, and the spandex core wire is straightened; The pre-draw ratio, the percentage of spandex is reduced, and the degree of crimping of the outer fiber is large. However, when the drafting is too large, the deformation amplitude of the spandex yarn is close to the critical value of the deformation, which will cause the strength of the covered yarn to decrease, but it is advantageous for the coated yarn to be evenly dried.

We has a wide selection of winding machines capable of attending commercial and industrial setups. You will find full-automatic yarn winding machine, semi-automatic yarn winding machine, and also manual yarn winding machine.

The durable and efficient range of premium quality polyester yarn winding machine. Highly appreciated for their efficiency and superior quality, they are quality tested before making the actual delivery to ensure that we offer zero defect range.

The spandex or Latex covering yarn is very popular to use for garment elastic tape or fabric. This Latex Spandex after processed by Latex Spandex Covering Machine, the outside of Latex and Spandex will be covered one yarn or two yarns which is controlled the elongation of Latex and Spandex. Also the yarn can protect the Latex and Spandex to be defect. for this reason, the final product will be smooth and get even after use the covering yarn.
