Background technology
Polyster fibre sewing thread includes polyester filament sewing thread and dacron short silk sewing thread, and polyester filament sewing thread has intensity height, line matter is soft, nothing is gone mouldy, seamability is good, physicochemical properties stablize the advantages such as non junction, it is widely used in the fields such as high-grade dress ornament, case and bag, shoes and hats, military supplies.
The technology of domestic and international sewing thread polyester filament is mainly spun and is drawn one-step method (FDY method (FULLDRAWYARN)), UDY-DT two-step method and POY-DT (PARTIALLYORIENTEDYARN) two-step method. FDY method polyester slice with high viscosity, spins and needs to set up annealing device in journey, and manufacturing cost is high, especially produces during the fine denier filament of below 150D more prominent. UDY-DT two-step method first spins undrawn yarn, then carries out multistage super drawing, but the intensity of the polyester filament obtained is not high, lacks effective sizing, and percent thermal shrinkage is higher, substantially superseded. Chinese patent CN200610085250, adopts POY-DT two-step method to sequentially pass through the operations such as one-level stretching, nervous thermal finalization, secondary drawing, relaxation heat setting and winding and produces fine denier high intensity low shrinkage flatness type polyester filament. The polyester filament intensity obtained and boiling water shrinkage can meet the requirement of medium-to-high grade long filament sewing thread. But, its technological process is long, and in energy consumption height, production process, end breakage rate is higher, causes production cost to remain high.
Producer is seldom had to adopt the mode adding Masterbatch to prepare high-strength terylene filament in black at present, its reason is that inorganic carbon black particle has not meltbility, skewness in the fibre during high drafting, easily form cohesion, increase along with draft ratio, end breakage rate increase is more notable, to such an extent as to prepared by the method that black high-strength silk still adopts dyeing.
