GB/T 43015-2023 in English

Interpretation of the test method for dry heat shrinkage of synthetic staple fibers

1. Background of standard formulation

With the development of the textile industry, synthetic fibers are increasingly used in clothing, home furnishings and industrial materials. In order to ensure product quality and performance consistency, the GB/T 43015-2023 standard came into being, aiming to unify the test method for dry heat shrinkage of synthetic staple fibers.

2. Comparison of standard frameworks

The following table shows the comparison of key dimensions of this standard with relevant international standards:

Standard dimensions	GB/T 43015—2023	ISO international standard
Scope of application	Synthetic staple fibers	All types of chemical fibers
Test temperature	Depending on fiber type (such as polyester, polyamide, etc.)	Uniform high temperature treatment
Accuracy requirements	Accurate to 0.01mm	Accurate to 0.1mm

3. Explanation of professional terms

4. Implementation suggestions

1. Train operators to ensure they are familiar with the standard content and instrument usage.
2. Select instruments and equipment that meet the accuracy requirements and calibrate them regularly.
3. Establish a quality control system, including data recording and analysis mechanisms.
