GB T 8629 Domestic washing and drying procedures for fabrics
The GB T 8629 standard provides a comprehensive set of domestic washing and drying procedures specifically designed to assess the dimensional stability and shrinkage properties of fabrics. This testing is crucial for ensuring that textiles maintain their size and shape after repeated home laundering, which is particularly important in sectors like clothing manufacturing, interior design, and textile retail.
Quality managers and compliance officers rely on this test to ensure product consistency and meet consumer expectations regarding fabric durability and performance. R&D engineers use these procedures to optimize the design of new fabrics or improve existing ones by understanding how various factors such as washing temperature, detergent type, and drying conditions affect shrinkage and dimensional stability.
The standard is applicable to a wide range of woven and knitted fabrics used in apparel, home textiles, and industrial products. The testing procedure simulates real-world domestic washing and drying cycles, providing data that can be used for quality assurance, product development, and compliance with international standards like ISO 13938-2.
The GB T 8629 test involves several key steps: fabric sampling, pretreatment (if necessary), washing in a washing machine according to specified parameters, drying under controlled conditions, and measurement of the fabric dimensions before and after testing. The standard specifies the use of specific detergents and water temperatures to simulate domestic conditions accurately.
By conducting this test, manufacturers can ensure that their products meet both internal quality standards and external regulations, thereby enhancing customer satisfaction and protecting brand reputation. Additionally, the results from these tests are valuable for purchasing departments in selecting suppliers who adhere to rigorous testing protocols.
| Key Parameters | Description |
|---|---|
| Washing Machine Type | Standard domestic washing machine with a capacity of 5-7 kg. |
| Water Temperature | 40°C ±2°C for cold water wash, 60°C ±2°C for warm water wash. |
| Detergent Usage | A specified amount of household detergent appropriate to the fabric type and washing temperature. |
| Drying Conditions | Room temperature air drying or tumble drying at 60°C ±2°C for a specific duration. |
The testing process is designed to be robust, replicating the conditions that consumers would experience in their homes. This ensures that the results are relevant and reliable indicators of fabric performance under realistic circumstances. Compliance with these procedures helps manufacturers produce products that not only meet but exceed customer expectations for durability and comfort.
Scope and Methodology
The scope of GB T 8629 covers the domestic washing and drying processes used to evaluate the dimensional stability and shrinkage properties of fabrics. The methodology involves several key steps, including sample preparation, washing in a domestic washing machine, drying, and measurement.
- Sample Preparation: A representative sample is selected from the batch or production run.
- Washing: Samples are washed using a standard domestic washing machine with specific detergent and water temperature as per the test requirements.
- Drying: The washed samples are dried according to specified conditions, either air-dried at room temperature or tumble-dried under controlled heat.
- Measurement: Dimensions of the fabric are measured before washing and drying, then again after the process is complete. Changes in dimensions indicate shrinkage and loss of dimensional stability.
The standard specifies exact conditions for each step to ensure consistency and repeatability. This approach guarantees that the results accurately reflect the performance of the fabrics under domestic washing and drying conditions.
