Automatic Shrinkage Measurement System for Textiles
In textile manufacturing, the compressive shrinking process can cause elongation and shrinkage inconsistencies which negatively affect product quality and overall production costs. Manual stick testing is performed by a production operator who places ink marks on the fabric roll before the shrinkage processing, then manually measures the marks to calculate shrinkage after shrinkage processing. This is the production method most trusted to predict residual shrinkage and still widely used today. Traditionally, manufacturers have managed and controlled the cost of shrinkage inconsistencies by stick - testing a small portion of fabric (<0.1%) and adjusting compressive shrinking factors to obtain the target shrinkage while ignoring the untested 99+%. Precisely measuring shrinkage of 100% of the fabric would yield the highest quality product but has not been practical... until now.
