HAST-01 Hot Air Thermal Shrinkage Tester

Application
HAST-01 Hot Air Thermal Shrinkage Tester conforms to ASTM D5591 and ASTM D4974
and is used for the measurement of the thermal shrinkage force and rate of
yarns and cords in air at controlled temperature. It is applicable to yarns and
cords made of nylon, polyester, and other polymers, etc.
Principles
ASTM D4974 shrink rate test:
A relaxed specimen of yarn or cord is subjected to dry heat for a specified
time under a specified tension. The percent of shrinkage is displayed on the
screen while the specimen is still under tension and exposed to heat.
ASTM D5591 shrink rate test:
A specified length of yarn or cord is fixed at a grip and the other end is
mounted with a pretension mass, then the mass is removed and the end was
connected to a loadcell. After that the yarn or cord is exposed to dry heat at
a controlled temperature. The shrinkage force induced in the specimen is read
from the tester.
Sample Types
dipped polyester cords, dipped polyester yarns, cords and cords made of nylon
and polyester fibers, dipped nylon 66 cords, dipped nylon 6 cords, dipped
polyester cords, dipped para-aramid cord, dipped polyester cord, tire cord,
polyester industrial filament, etc.
