Characteristics of spandex coated yarn

1. Air-coated yarn (ACY for short) is a kind of yarn in which coated fiber filaments and spandex filaments are drawn through a certain nozzle at the same time, and are regularly sprayed by highly compressed air to form rhythmic network points. The fabric feels soft and smooth;

Second, the mechanical wrapping yarn (abbreviated as machine package, abbreviated as SCY in English) is that the wrapped fiber filaments are continuously rotated, wound on the core spandex stretched at a uniform speed, and twisted into a twist (abbreviated as TPM in English), and the fabric style is flat and crisp.

Empty yarn and machine-wrapped yarn have their own advantages and disadvantages in downstream weaving. Generally, empty bales need sizing when warping on air-jet loom, otherwise the fabric is easy to pilling and break, but beating-up can be used directly. Considering the cost alone, the capacity of empty package is much higher than that of machine package, which makes the price lower than that of machine package, which is convenient to reduce the cost of downstream weaving factories. Although the core yarn is not exposed, it is generally not easy to cause quality problems in spinning and weaving except for uneven twist, but the output is low, so the price is more than 5000 yuan /T higher than that of the empty package with the same specification, and the price of fine denier covered yarn is even higher than that of the empty package with the same specification, which greatly increases the cost of using machine package.
