PREPARATION METHOD OF POLYESTER STRETCHED FILAMENT AND POLYESTER STRETCHED FILAMENT PRODUCED BY THE METHOD

摘要

The present invention provides two different types of polyester filament yarn having the believers, that believers are reviewed as weigh greater than 2-4% by weight of titanium dioxide (TiO ₂ ) subjected to false-twist processing multifilament yarns and screening as polyester filament yarn under conditions that do not use air entangled honseom which after column containing the which relates to a method for producing a polyester false-twist yarn and a polyester false-twist yarn manufactured by it, characterized in that, it was prepared in advance by Shin composite polyester false-twist process does not give the false-twist yarn during false-twist process heat produced by the present invention did not occur because of a change in the microstructure of the polyester fiber dyeing during screening and second Sagan dyeing difference does not occur, of the titanium dioxide (TiO ₂ ) because using the present invention is contained as a result weigh drape and a dry sense of processed fabric and knitted fabric made captive has an excellent advantage.
