Application
The Fabric Shrinkage Template & Ruler is ideal for shrinkage testing according to various international standards. Made with a high-transparent plexiglass plate, this template combines multiple test standards in one, featuring shrinkage and stretch scales (0%~20%) and measurement lengths (500mm, 350mm, 250mm). The frame size is 610mm x 610mm, providing a clear and reliable method for assessing fabric shrinkage and stretch.
What is Fabric Shrinkage?
Fabric shrinkage refers to the reduction in fabric size, typically after undergoing home laundering procedures. This common defect affects fabric quality and can be influenced by various factors such as washing temperature, rinse temperature, and dyeing processes.
Scope and Purpose of Fabric Shrinkage Test
Shrinkage testing is a vital step in the textile industry worldwide, used to measure dimensional changes in woven and knitted fabrics after repeated home laundering. This test detects shrinkage in textiles when washed using conventional household methods.
Testing Method
Marking Procedure
To begin testing, place the specimen on a flat, smooth surface and mark at least three pairs of points in both the length and width directions. The distance between marks should be a minimum of 350mm, with no mark less than 50mm from the specimen’s edges. Ensure the marks are spaced evenly.
Test Method
- Lay the fabric flat on the surface, removing wrinkles without stretching.
- Position the ruler on the specimen carefully to avoid distortion.
- Record the distance between the marked pairs to the nearest 1mm.
- Flatten the fabric to prevent measurement distortion.
Report Content
- The average dimensional change rate in both the length and width directions.
- Laundry conditions, including water temperature, water level, and washing procedure.
- Drying conditions, including temperature and drying procedure.
- Any observed changes in appearance after washing.
