1. Q: What is the difference between SCY and ACY?

A: Air covered yarn (ACY for short) is a yarn that draws outsource fiber filament and spandex filament through a certain type of nozzle at the same time and forms rhythmical network points through regular injection pressure of highly compressed air. Its fabric feels soft and smooth;

Mechanical covered yarn (machine wrap for short, SCY for short) is the outsourcing fiber filament constantly rotating and winding on the core silk spandex which is drawn at a uniform speed. It has twist (TPM for short) after twisting, and the fabric style is smooth and crisp.

Empty - wrapped and machine - wrapped yarns have their advantages and disadvantages in the weaving of downstream mills. When the empty bag is warped on the air-jet loom, it usually needs sizing, otherwise the fabric is easy to be bristling and broken, but it can be used directly by beating the weft. Considering the cost alone, the production 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 the downstream textile factory. Although the machine bale does not expose the core yarn, it is not easy to produce quality problems in spinning and weaving except for the twist irregularity, but the production is low, so the price is higher than the empty bale of the same specification of RMB5000/T, and the price of fine denier coated yarn is even higher than the empty bale of the same specification of RMB10000/T, which greatly increases the cost of using the machine bale.

2. Q：What is the technical point of covered yarn?

A: During the spinning process, Spandex Stretch is an important process parameter, which affects the elasticity of Covered Yarn and fabric, as well as the strength and stretch, evenness of strip and creep properties of covered yarn. The predraft ratio of spandex is too small, which can not give full play to the advantage of elastic fabric elasticity. When the draft is too high, it is difficult to spin yarn, and it is easy to cause yarn breaking, and the product quality decreases accordingly. In addition, the percentage content of spandex also affects the elasticity of the covered yarn, high content, good elasticity. Under the condition of certain specifications of spandex wire, the percentage of spandex wire decreases with the increase of drafting ratio, that is, the predrafting ratio of spandex is inversely proportional to the percentage of spandex yarn.

3. Q: How much quantity can load in one 40HQ of this item Denim Air Covered Yarn 2070?

A:21 tons usually can load.
