What is Textile Shrinkage Testing and how to do the test

Introduction to Textile Shrinkage Testing

Overview of Textile Shrinkage Testing

Textile shrinkage testing is a crucial process in the textile industry that determines how much a fabric will shrink when washed or dried. Measuring the change in dimensions of a fabric after subjecting it to specific conditions such as washing, drying, and ironing is an integral part of the testing process. The test results yield valuable information about the quality and durability of fabrics, which manufacturers, retailers, and consumers can utilize for decision-making purposes.

Importance of Textile Shrinkage Testing

The importance of textile shrinkage testing cannot be overstated. It helps to ensure that fabrics maintain their original size and shape even after multiple washes or cleaning cycles. This is particularly important for clothing items where customers expect consistent sizing throughout the lifetime of the garment. Without proper testing, there may be significant variations in size which could lead to customer dissatisfaction with the product.

Furthermore, shrinkage testing also plays a pivotal role in determining whether new fabrics are suitable for particular applications such as bedding or upholstery where dimensional stability is critical. Additionally, researchers rely on accurate shrinkage data to develop new technologies and processes that improve fabric performance.

Overall, textile shrinkage testing serves as an essential tool for ensuring quality control within the textile industry. By using precise equipment like DaRong’s Textile Shrinkage Tester, professionals can obtain reliable data needed to make informed decisions regarding manufacturing processes and product development initiatives.

Textile Shrinkage Testing Method

What is textile shrinkage testing?

Textile shrinkage testing is a process of measuring the amount of shrinking that occurs in fabric after it has been washed or dried. Shrinkage refers to the reduction in size and shape of garments, which can lead to fitting issues and dissatisfaction among customers. Shrinkage can occur due to various reasons such as improper washing techniques, use of incorrect detergents, etc.

Why is textile shrinkage testing important?

Textile shrinkage testing is crucial for maintaining quality control standards within the textile industry. It helps manufacturers ensure that their products meet specific criteria for dimensions and sizing after washing or drying cycles. This prevents any potential issues with customer satisfaction, returns or complaints about product inconsistency.

Testing method for textile shrinkage testing

To conduct a reliable test on textiles using DaRong’s Textile Shrinkage Tester, follow these steps:

  1. Cut out a sample from the fabric being tested according to standard specifications.
  2. Condition the sample at room temperature (20-25°C) with 65% relative humidity (RH) before conducting tests.
  3. Accurately measure the conditioned sample and mark it with two lines perpendicular to each other along its lengthwise direction. These lines will help measure the sample’s original dimension before washing/drying.
  4. Subject the prepared samples to different wash cycles based on specified conditions, including water temperature, detergent type, time duration, etc.
  5. Tumble-dry the samples under standard conditions.
  6. After the washing and drying process, re-measure the samples along the marked lines drawn across them before the wash cycle.
  7. To ensure comparability between test results from different laboratories, it is essential to standardize common procedures such as detergent selection, washing machine type, number/ratio/size/materials of specimens per load, tumble dryer settings, and time elapsed since the end of the last rinse cycle.

By following these standardized procedures, you can obtain accurate and comparable results when using DaRong’s Textile Shrinkage Tester for textile shrinkage testing.

Overall,DaRong’s Textile Shrinkage Tester provides an effective and efficient method for measuring textile shrinkage, which is vital for ensuring consistent quality within the textile industry.

Preparation for textile shrinkage testing using DaRong’s Textile Shrinkage Tester Y(B)089T

Before starting the test, it is important to prepare the fabric sample according to specific requirements. Cut the sample into a square or rectangular shape with dimensions of at least 20 cm x 20 cm. After cutting, mark two parallel lines on opposite sides of the fabric sample, which will serve as reference points during measurement.

Next, adjust the temperature and humidity settings of the tester according to standard testing conditions. This is crucial because changes in temperature and humidity can affect the accuracy of results.

Steps for textile shrinkage testing using DaRong’s Textile Shrinkage Tester Y(B)089T

1. Place the prepared fabric sample onto the flat surface of the tester.

2.Securely clamp both ends of one side of the fabric using clamps provided by Darong’s machine.

3.Set up program parameters such as time duration (usually from 5-60 minutes), temperature level (usually between 40°C – 90°C), and number settings (number counts per minute).

4.Turn ON button indicated on touch screen panel

5.The digital display screen will show all values related to current measurements including moisture content if appropriate sensor installed.

6.After reaching specified time duration turn off machine

7.Remove specimen from clamps carefully without stretching

8.Measure distance between marked lines before & after experiment respectively

9.Calculate %shrinkages based on results obtained.

Interpreting the results of textile shrinkage testing using DaRong’s Textile Shrinkage Tester Y(B)089T

After completing the test, calculate the percentage shrinkage by comparing the length difference between reference lines before and after washing. If there is a decrease in length, it indicates that the fabric has shrunk. Calculate the percentage of shrinkage using the following formula:

Percentage Shrinkage = [(Initial Length – Final Length)/Initial Length] x 100

You can compare the results with industry standards or previous tests conducted on similar fabrics to determine if they meet dimensional stability requirements.


In conclusion, textile shrinkage testing is an essential process that ensures the quality and durability of textile products. And DaRong’s Textile Shrinkage Tester Y(B)089T provides accurate and reliable results for this testing. By using this tester, textile industry professionals can determine the amount of shrinkage in different fabrics under different conditions. This information helps them make informed decisions about fabric selection, production processes, and product design to create high-quality and long-lasting textiles. With its user-friendly interface and advanced features, DaRong’s Textile Shrinkage Tester Y(B)089T has become a popular choice among researchers, students, and industry professionals who demand precision in their work.
