What is Fabric Shrinkage?
Fabric shrinkage is a common phenomenon that the defect of the fabric which is subjected to home laundering procedures. To determine the quality of the fabric, shrinkage is an important element which is needed to consider. There are many elements to affect the dimensional changes of the fabrics such as the washing temperature, rinse temperature, dying procedures, etc.
Scope and Purpose of Fabrics Shrinkage Test
The shrinkage rate of textiles is an important item which must be tested in the textile industry of every country at present. At present, the countries with different standards of shrinkage rate of textiles carry out their own standards.
This testing method is suitable for the size change of woven fabric and knitted fabric after multiple household washing, and the shrinkage of various textiles after washing by conventional household washing method is detected.
Marking
Place the specimen on the measuring table and make at least three pairs of marks on it in both length and width directions. Ensure that the distance between the marks of each pair is at least 350mm, that no mark is less than 50mm from the edges of the specimen and that the measuring points are regularly spaced across the specimen.
Test Method
Lay the specimen flat on the smooth, flat surface and remove wrinkles without stretching the specimen. Place the ruler on the specimen, taking care to avoid distortion of the specimen. Record the distance between the pairs of marks to the nearest 1mm. Flatten the wrinkled specimen by the instrument so that the measurement does not cause deviation.
Report Content
The change rate of the dimension in the direction of length and the width direction, taking the average value of each measurement.
Describe the laundry conditions used, including water level, water temperature, and laundry procedure.
Describe the dry conditions used, including drying procedures and temperature.
Explain the appearance change of the test sample after washing.

What is Shrinkage Formula in Textile?
The shrinkage formula in textiles is used to calculate the percentage reduction in the dimensions of fabric after it undergoes processes like washing, drying, or exposure to heat. The formula is:
Shrinkage (%)=Original Dimension−Final DimensionOriginal Dimension/Original Dimension x 100
Explanation:
Original Dimension: The initial measurement of the fabric before testing (e.g., length or width in centimeters or inches).
Final Dimension: The measurement of the fabric after the test (after washing or drying).
Shrinkage (%): The percentage of shrinkage in the fabric.
Example:
If a fabric has an original length of 100 cm and a final length of 95 cm after washing:
Shrinkage (%)=100 cm−95 cm/100 cm×100=5%
This means the fabric shrank by 5%.
What causes fabric shrinkage?
Raw Materials: Different raw materials for fabrics result in different shrinkage rates. Generally, fibers with high moisture absorption expand when soaked, increasing their diameter and shortening their length, leading to greater shrinkage. For example, viscose fibers can absorb up to 13% moisture, while synthetic fibers have poor moisture absorption, resulting in lower shrinkage rates.
Density: The density of the fabric influences its shrinkage rate. If the warp and weft densities are similar, their shrinkage rates will also be close. Fabrics with high warp density will experience more shrinkage in the warp direction, while fabrics with greater weft density will have more shrinkage in the weft direction.
Yarn Count: The thickness of the yarn affects the shrinkage rate. Fabrics made from thicker yarns will have a higher shrinkage rate, while those made from finer yarns will experience less shrinkage.
Production Process: Different production processes result in varying shrinkage rates. Generally, fabrics that undergo multiple stretching during weaving and dyeing, combined with longer processing times and higher applied tension, will exhibit greater shrinkage, and vice versa.
Fiber Composition: Natural plant fibers (such as cotton and linen) and regenerated plant fibers (like viscose) tend to absorb moisture and expand more easily than synthetic fibers (such as polyester and acrylic), resulting in higher shrinkage rates. Wool, due to the scaly structure on its fibers, is also prone to felting, affecting its dimensional stability.
Fabric Structure: Typically, woven fabrics have better dimensional stability than knitted fabrics, and high-density fabrics are more stable than low-density ones. In woven fabrics, plain weaves usually have lower shrinkage rates than fleece fabrics, while in knitted fabrics, plain stitches shrink less than ribbed stitches. During the production process, fabrics inevitably experience stretching during dyeing, printing, and finishing, which creates tension. When the fabric is exposed to water, this tension is easily released, leading to shrinkage. Pre-shrinking is commonly used to address this issue.
Washing and Care Process: The washing, drying, and ironing processes can all affect the shrinkage of fabrics. For instance, hand-washed samples tend to have better dimensional stability than machine-washed ones, and washing temperature also impacts stability. Generally, higher temperatures lead to lower stability.
What are fabric shrinkage standards?
Fabric shrinkage standards are established guidelines, such as AATCC 135, ASTM D standards, ISO 5077, BS EN 14421, and JIS L 1096.
What is the shrinkage rate of general fabrics?
The shrinkage rates of general fabrics can vary widely depending on the fiber composition, weave, and finishing processes. The shrinkage rates for general fabrics are as follows:
Cotton: 4% to 10%
Synthetic Fibers: 4% to 8%
Cotton-Polyester Blends: 3.5% to 5.5%
Natural White Fabric: 3%
Wool Denim: 3% to 4%
Sateen: 3% to 4.5%
Printed Fabric: 3% to 3.5%
Twill Fabric: 4%
Workwear Fabric: 10%
Rayon: 10%
What is the detailed fabric shrinkage test procedure?
1 Sample Preparation
Select Fabric Samples: Cut the fabric into standardized dimensions (e.g., 30 cm x 30 cm) to ensure uniformity.
Mark Samples: Use a fabric marker to mark the original dimensions and any reference points on the fabric.
2 Pre-Treatment (Optional)
Pre-Wash Samples: If required, pre-wash the samples according to the care instructions to remove any finishes that could affect the results.
3 Initial Measurement
Measure Dimensions: Use a ruler or fabric measuring tape to measure the length and width of each sample accurately. Record the dimensions (L1 and W1).
4 Washing Procedure
Select Washing Conditions: Define the washing method, including water temperature, detergent type, and cycle duration based on relevant standards (e.g., AATCC or ISO).
Wash Samples: Place the fabric samples in a washing machine and run the cycle according to the chosen conditions.
5 Drying Procedure
Drying Method: After washing, dry the samples according to the specified method (e.g., tumble dry, line dry, or air dry).
Avoid Over-drying: Ensure not to over-dry the samples, as this can impact the accuracy of the results.
6 Post-Wash Measurement
Measure Dimensions Again: After drying, measure the dimensions of each sample (L2 and W2) using the same method as the initial measurement.
Record Results: Note the dimensions after washing and drying.
7 Calculating Shrinkage Rate
Use the SmartShrink Shrinkage Rate Tester.
8 Analysis and Reporting
Analyze Results: Compare the calculated shrinkage rates against applicable standards to evaluate fabric performance.
Prepare a Report: Document the test conditions, methods, measurements, calculations, and findings for quality control and compliance purposes.
What types of fabrics are suitable for the dry shrinkage rate testing method and the wet shrinkage rate testing method?
The dry shrinkage rate testing method is suitable for synthetic fibers (such as polyester and nylon) and certain high-performance fabrics, while the wet shrinkage rate testing method is more appropriate for natural fibers (such as cotton and wool) as well as most common fabrics.
Can the SmartShrink handle different fabric types?
Yes, the SmartShrink can handle different fabric types, including natural fibers (like cotton and wool), synthetic fibers (such as polyester and nylon), blended fabrics, and technical fabrics, ensuring accurate and reliable shrinkage measurements for a wide range of textiles.
Can the testing results be integrated with production software?
Yes, the test results can be directly uploaded to the factory’s ERP or laboratory LIMS system.
