Digitization Intelligent production workshop Testing

DETECT

The testing center of Hangzhou Hangmin Damei dyeing and finishing Co., Ltd. is a laboratory accredited by China National Accreditation Service for conformity assessment (CNAs). The accredited testing capabilities include 26 items in 9 categories, including pilling, stretching and tearing.

DATACOLOR800 Colorimeter

Using Datacolor color measuring software, we can quickly and accurately measure and match the color of the fabric. Using the data, we can analyze the color difference between the fabric samples. The color matching software can use the input Dyeing Group to match and modify the target color.

JAMES HEAL Martindale pilling ball tester

Martindale pilling ball tester: under the specified pressure, the circular sample and the fabric or wool fabric of the same material will conduct circular friction around the center of the sample and perpendicular to the surface of the sample according to the movement trajectory of Lissajou figure. After reaching the specified friction stage, the fabric surface will produce wool balls, and the pilling grade of the sample will be evaluated.
