Abstract :
Experimental and statistical properties of bi-shrinkage yarns (BSY) were studied by combining
multifilament yarns of poly(ethylene terephthalate) containing partially oriented yarn and fully drawn yarn with different finenesses. In this procedure, different twists per meter (500,
1000, and 1500 tpm) were applied to different BSYs. Then
tensile, shrinkage, and appearance properties of the samples
were analyzed. The appearance properties of the BSYs showed
that they are very similar to multifilament textured yarns.
The most important factor affecting the BSYs properties
is the filaments’ number of yarns. The best mechanical,
shrinkage, and appearance properties were observed in the
samples containing two components with the same number
of filaments (regular or microfilament yarns). Also, statistical
studies showed the most important factor affecting the BSYs
properties was filaments’ number of yarns. Moreover, the number of twists per meter of BSY’s is an effective parameter.
