STUDI RANCANG BANGUN ALAT PENGUKUR BOILING WATER SHRINKAGE PADA BENANG TEKSTIL

Boiling water shrinkage measurement is a critical method in the textile industry for evaluating the dimensional stability of yarn, particularly during finishing processes which involve hot water. This study aims to design and develop a yarn shrinkage measurement device using the boiling water shrinkage method, referring to ISO 18066:2015 standard. The prototype is designed to be compact and energy-efficient, utilizing easily accessible smaller materials and components using a microcontroller for manual temperature control. The device was tested on 100% acrylic yarn, with results showing accuracy comparable to industrial-grade testing instruments used by PT Hanil Indonesia. A t-test analysis revealed no significant difference between the developed device and industrial testing tools, indicating that the prototype can provide reliable and accurate measurement results. This research offers a practical, cost-effective solution for yarn quality control in both the textile industry and educational institutions, enhancing testing capabilities for textile materials.
