Comparison between fibres of standard linear density & microfibres
Tenacity [8]
• The tenacity value of fine dpf POY spun is higher than that of normal dpf POY.
• The tenacity value of fine dpf acrylic spun is higher than that of normal dpf Acrylic.
Elongation at break
• The elongation at breake value of fine dpf POY spun is lower than that of normal dpf POY.
Uster
• The Uster value of fine dpf yarn is slightly higher than that of normal dpf yarn.
Draw force
• The draw force value of fine dpf yarn is higher than that of normal dpf yarn.
A comparison of the properties o polyester and acrilic microfibres with different linear densites are
presented in Table 2.
