Beschreibung
Zusammenfassung:	The invention relates to a manufacturing technology of a dacron glossy special-shaped semi-elastic drafting long wire. The manufacturing technology includes special designs of polyester raw material low-shrink pre-treatment, high-modulus bending glossy melt treatment, melt multi-stage directly-melting spinning, filter screen spinning cooling oiling semi-elastic drawing treatment and includes optimization of relative parameters to form the manufacturing technology of the dacron glossy special-shaped semi-elastic drafting long wire. By means of the manufacturing technology, defects of poor glossiness and low elastic drafting performance in the prior art are overcome so that the long wire is more excellent in photo-refraction, photo-reflection, thermal shrinkage, semi-elasticity, drafting performance, elastic texture, glossiness and low elasticity.
