The difference between ACY and SCY

1.Air-wrapped yarn, short for empty package, abbreviated as ACY in English, is a yarn with rhythmic network points formed by drawing outer filament and polyurethane filament through a certain type of nozzle at the same time and injecting pressure with high compression air regularity. The fabric feels soft and smooth.

2.Machine-wrapped yarn, abbreviated as machine package, abbreviated as SCY in English, is a twisted and twisted core-spun spandex with constant rotation and winding of wrapped filament. Its main characteristics are smooth and straight fabric style.

The yarn of empty bag and machine yarn has advantages and disadvantages in weaving.Empty bags usually need sizing when warping on air-jet looms. Otherwise, the fabric is easy to pick up and break, but beating-up can be used directly.Considering the cost alone, the empty-contract capacity is much higher than the air-bag capacity, which makes the price lower than the air-bag, and is convenient to reduce the cost.Although the machine package does not expose core yarn, it is not easy to produce quality problems in spinning and weaving except for uneven twist, but the output is not higher than that of empty package. Therefore, the price of fine denier covered yarn is higher than that of empty package of the same specifications by RMB5000/T, and the price of fine denier covered yarn is even higher than that of empty package of the same specifications by RMB10000/T. Therefore, the use of machine package is greatly increased cost.
