The Air spandex-coated yarn and the Conventional spandex-coated yarn weaving factory have their own advantages and disadvantages. Empty bags generally need to be sized when warping on an air jet loom, otherwise the fabric is easy to smash and break, but the beating can be used directly. From the cost consideration alone, the empty package capacity is much higher than the machine package capacity, so the price is lower than the machine package, which is convenient to reduce the cost of the downstream weaving factory.
Although the Conventional spandex-coated yarn is not exposed to the core wire, it is generally difficult to produce quality problems in spinning and weaving except for unevenness of the twist, but the output is low, and the price is higher than the empty bag of the same specification by RMB5000/T or more. The price of the covered yarn is even higher than the empty package of RMB10000/T of the same specification, thus greatly increasing the cost of using the machine package.
