Research Of The Process Performance Of The Full-dull Polyester Filament

Full dull polyester filament has a rather large market position as a kind of differential products. Nowadays many producers make it in the process of master batch. The process of full dull chip has the advantage of even quality as the problem in the control of spin and draw because of the low content of stability agent in the production of full dull chip in the large equipment. It is discussed in this article that the process performance of the full-dull polyester filament. The content of TiO₂ and –COOH has the obvious effect to the performance. The process condition, such as dry, quenches and takes up, also influence the final product. And the better quality products could be make through the control the parameters of heat stress, evenness, unwind factor and disability.
