Testador de contração térmica de ar quente HAST-01

Introduction to the Thermal Shrinkage Tester

The Thermal Shrinkage Tester (e.g., Testador de contração térmica de ar quente HAST-01) is designed to measure the thermal shrinkage force and rate of yarns and cords under controlled heat conditions. It is primarily used for testing yarns and cords made from materials such as nylon, polyester, and other polymers, commonly used in industries like textiles, automotive, packaging, and industrial manufacturing.

This high-precision tester ensures manufacturers can assess the shrinkage behavior of yarns and cords in real-world conditions, making it essential for ensuring quality and durability across multiple applications.

ASTM D5591 Shrinkage Force Test

The ASTM D5591 standard outlines the method for measuring the shrinkage force of yarns and cords. This test involves fixing one end of a yarn or cord and attaching a pre-tension mass to the other end. After removing the mass, the specimen is exposed to dry heat at a controlled temperature, and the shrinkage force is measured.

• Purpose: To determine the shrinkage force when yarns and cords are exposed to heat, ensuring compliance with performance standards.
• Test Parameters:
  • Temperature range: Ambient to 250°C
  • Shrink force resolution: 0.01N
  • Shrink force range: 0-50N (customizable)
• Secondary Keyword: Yarn Thermal Shrinkage Force.

ASTM D4974 Shrinkage Rate Test

The ASTM D4974 test method is used to measure the shrinkage rate of yarns and cords. A specimen is subjected to dry heat for a specified duration under a certain tension, and the shrinkage percentage is recorded while the specimen remains under tension and exposed to heat.

• Purpose: To measure the shrinkage rate of materials under controlled conditions, ensuring the materials meet specific durability and performance criteria.
• Test Parameters:
  • Temperature accuracy: ±0.1°C
  • Shrinkage resolution: 0.01% (100% corresponds to 250mm of length)
• Secondary Keyword: Yarn Thermal Shrinkage Force.
