Polypropylene is an important thermoplastic fibre. It enjoys a prominent
status next only to polyester in the synthetic fibre domain. This fibre
has some excellent properties which are even considered superior to
nylon for carpet use in terms of soil repellence and other related
attributes. However the polyproylene fibre has not made significant dent
in the apparel sector due to inherent properties such as hydrophobicity,
poor handle properties and absence of satisfactory dyeability. The
important way for entry of polypropylene into the apparel sector is
through texturizing process, which improves the feel and increases water
retention ability of polypropylene yarn. It is therefore of significant
interest to researchers to understand the effects of colourants and
carrier used for mass colouration on the texturizability and fibre
properties. In this book, studies on three types of coloured
polypropylene yarns, viz grey, coal grey and black have been reported.
This book also presents optimized texturing parameters for white and
coloured polypropylene yarn. The effect of secondary heater temperature
and stabilizing over feed has also been reported.
