The development of a system to produce single covered yarn and double covered yarn and improvement in weaving technique, the knitting system, dyeing & printing and finishing techniques have recently been so remarkable in Japan, and they are important factors in the production of stretch fabric textile.

It will be possible to reduce crease, moire and edge mark on the gray fabric stored in a warehouse if the "first-in, first-out" method based on computer stock control is strengthened. For example, Toyobo Co., Ltd. has already established a method to store the gray fabric of stretch fabric without loading pressure. The gray fabric is wrapped with hermetic film so that any oiling agent used for the weaving process does not ooze out.

In China, many factories still have problems with uneven dyeing even when they dye pure polyester. Their goal is to find the causes of the problem by the end of 1998.

The conditions of relax scouring on stretch fabric vary depending on the type that yarn makers produce. The heat setting condition, the factors that should be taken into account for dyeing & printing and finishing processes vary depending on the type of yarn. So, it is necessary to be able tell the most suitable treatment according to each situation. This approach is being improved in Japan.
