摘要

"The sea island type composite fiber for warp aveludamento treated with tricu00c8, their process of preparation and velvet fabric by tricu00c8 made".The present invention relates to a fiber composed of sea island type and a process for their preparation.According to the present invention.The fiber composed of sea island type warp knitted fabric with [or a velvet which is prepared by the method of stretching by trefilamento straight through the use of a polyester co opLu00edmero soluble in alkali as a component of sea and a polyester consisting mainly of polyethylene terefrtalato of more than 90% soft as a component Island,In which the composite fiber satisfies the following properties of thermo elastic and visco elastic: - the number of presence of peaks in the melting point: 4Temperature of the main peak of the melting point of the component sea (TMS): 220 ~ 235 198 C, temperature of main peak of the melting point of the component Island (TMI) 245 ~ 255 198 C,Temperature of the first peak of transition (T 244 ] of visco - elastic index (Tan sym ) 120 ~ 150 198 C and index value of visco - elastic [Tan sym 244 ] of the first transition peak (peak sym 0,10 - 0.20.The fiber of sea island type composite prepared by this envenu00e7u00e3o exhibits good properties of thermal shrinkage and excellent property of aveludamento and improves the appearance and touchThe tricu00f3 pronounced.
