Hot Air Thermal Shrinkage Tester For Yarn And Cord Thermal Shrinkage Force Tester

The Hot Air Thermal Shrinkage Tester (Model: HAST-01) is a state-of-the-art laboratory instrument designed to measure the thermal shrinkage force and rate of yarns, cords, and other industrial fibers exposed to controlled hot air environments. Meeting the exacting standards set by ASTM D5591 and ASTM D4974, this tester provides manufacturers, quality control laboratories, and researchers with reliable, precise measurements essential for product development and quality assurance in industries like packaging, food, beverage, pharmaceuticals, and textiles.

Applications of the Hot Air Thermal Shrinkage Tester

The Hot Air Thermal Shrinkage Tester is widely used to test the shrinkage characteristics of various yarns and cords such as polyester, nylon, para-aramid, and industrial filaments. Whether in research labs, manufacturing, or quality control settings, this instrument is crucial for determining the thermal stability of materials used in packaging films, medical textiles, food packaging, and more.

By applying controlled hot air at specific temperatures and tension settings, the Hot Air Thermal Shrinkage Tester measures both the rate and force of shrinkage, ensuring that manufacturers can produce materials with predictable shrinkage behavior under varying heat conditions.

Principle of Operation

The Hot Air Thermal Shrinkage Tester operates based on the principles outlined in ASTM D5591 and ASTM D4974. During testing, a sample material (such as a yarn or cord) is exposed to dry heat under controlled conditions. According to ASTM D4974, the specimen is subjected to a predefined tension while exposed to heat, causing it to shrink. The ASTM D5591 method involves fixing the specimen to a pretension mass and measuring the shrinkage force as the material is heated. The tester accurately records both the shrinkage force and rate of shrinkage, ensuring precise, repeatable results.
