This standard specifies the test methods for the boiling water shrinkage and dry hot air shrinkage of synthetic fiber (polyester, nylon, polypropylene) filaments - skein method and single fiber method. This standard applies to synthetic fiber filaments with a linear density less than 3000dtex. This standard does not apply to pre-oriented filaments.
