Abstract

The invention relates to a preparation method of a polyester FDY mother filament and a monofilament thereof. The method consists of: adding an antibacterial polyester melt containing a cuprous material into a conventional polyester melt pipe by a melt direct-spinning pipe adding way, performing mixing by a static mixer in the melt pipe, then carrying out melt spinning, cooling, drafting, heat setting and winding to obtain a polyester FDY mother yarn. According to the process, specifically, the spinning temperature is 292DEG C, the wind temperature is 16-18DEG C, the wind speed is 0.7-0.85m / s, the drafting temperature is 95DEG C, the drafting ratio is 1.8-2.2 times, the heat setting temperature is 150DEG C, the winding tension is controlled at 2.2-2.5cN, and the winding speed is 3900-4500 meter / minute. While acquiring direct economic benefits, the method provided by the invention also achieves considerable indirect economic benefits, and seizes the DTY emerging market under the current situation of fierce market competition. According to the invention, the antibacterial material is added to enhance the antibacterial properties of the fiber and expand its application scope.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a method for preparing polyester FDY mother silk and monofilament thereof. Background technique [0002] The key to the development of the textile industry lies in the development of new products. Products with multi-purpose, high performance and high added value using new technology, new equipment and new technology will become a new development trend. More and more companies have begun to join the ranks of developing new high-tech and differentiated functional chemical fiber products. [0003] Polyester filaments with a monofilament fineness of 10-30D are widely used in civil uses such as wedding dresses, evening dresses, warp-knitted fabrics, and industrial printing screens and ribbons. The traditional monofilament production is completed by UDY-DT process, the spinning speed is 700-900m / min, and the monofilament dyeing performance is uneven. This production proc...
