CONTRACTION FOR POLYESTER HARD-TWISTED YARN FABRIC AND FINISHING METHOD FOR RELAX

摘要

The present invention relates to a method for shrinking and re-racing a polyester staple fiber using superheated steam and high-pressure hot air,;The polyester fabric is woven or refined in a continuous drawing machine and the fabric is made into a rope in an atmospheric processing machine storage tank to produce a high speed fabric by a superheated steam (wet) and a hot (dry) And the reduction and re-racing work is performed, thereby improving the processing efficiency, thereby increasing the quality and productivity of the fabric and minimizing the generation of wastewater.;In general, fabrics are processed simultaneously in the rotary washer in order to expedite, refine and shrink, and relex. However, in the case of polyester lacquer weave or new lacquer weave, the fiber lining is strong and the shrinking property of the fiber is large and the touch is unique. Since it is necessary to separate the scouring, scouring, shaking and reeling operations, conventionally, the scouring, refining, shrinking and re-racing operations are performed using a rotary washer, a liquid dyeing machine and an air flour dyeing machine. Although the amount of wastewater is large due to the immersion process, various kinds of auxiliary operations are required, and there is a drawback that the operation is dangerous, the process is large, and the quality and productivity are poor;The present invention is a breakthrough invention in the processing of fabrics which satisfies the requirements of polyester woven fabrics or new-woven fabrics by simultaneously applying superheated steam (wet) and hot-air (dry) at the same time, enhancing quality and productivity, and minimizing the amount of wastewater.
