The Compaction Control System (CCS) controls course count by automating percent compaction of a compactor. Shrinkage uniformity is achieved using the CCS-300 to control the tubular compaction process to a uniform course count. The CCS-300 uses a PSM-100 Sensor System coupled with a Graphical User Interface to measure course count and adjust the compaction process, achieving seam-to-seam uniformity of course count - and thus uniform shrinkage. The functionality of the Compaction Control System is further enhanced with the integration of a Width Measurement Sensor for measurement and control of fabric width. Course count control, more predictable shrinkage, and width control - all in one powerful package.
Independent studies of fabric shrinkage show the finisher can affect the length shrinkage variation by controlling to specific course counts. A recent study investigated shrinkage variation as a function of yarn count variations. The differences in shrinkage variations which resulted from weight control versus course count control were compared.
The results of this study showed: Controlling to constant courses per unit length at constant width produced length and width shrinkage which varied by only about one percentage point. Controlling to constant weight per unit area at constant width produced length shrinkage which varied by up to six percentage points. The former variation will be acceptable to most customers while the latter variation is likely to prove unacceptable to demanding customers.
