Problems solved by technology

[0004] Today, although the traditional FDY polyester one-step spinning technology is quite mature, its FDY spinning equipment can only be used to produce polyester monofilament varieties, because FDY equipment is single-screw single-box equipment, and its spinning position cannot produce Composite yarn, each part can only be spun into one product (POY or FDY), and FDY also has only two sets of hot rolls for drafting and heating, of which the first set of hot rolls has only two rolls (both are Hot roll or a hot roll and a split roll), can only be used to produce polyester FDY monofilament, if it is impossible to combine the production of network yarn on such traditional equipment, it must be done on existing equipment Transformation, polyester one-step combined network yarn spinning device was born

Embodiment 1

[0016] A blending method of polyester medium-speed blended FDY and POY blended fibers designed in the present invention includes slice conveying and screening, slice drying, screw extrusion, melt spinning, blowing cooling, and is characterized in that: after cooling, they enter POY spinning respectively Filament and FDY spinning, after POY spinning, it enters the nozzle for oiling, and then enters the pre-internet; after FDY spinning, it enters the tanker for oiling, then enters the pre-internet, and then enters the hot roller for drafting, and then the POY and FDY filaments enter the guide The grooved godet is merged and compounded. After compounding, it enters the intermediate network, and then heats the roll to shape it, and then enters the main network to be wound and formed. During the production process, the winding speed is 3000 m / min, the hot roller GR 1 Temperature: 85°C; Number of wire winding turns: 7.5 to 10 turns; hot roller GR 2 Temperature: 100°C; number of coi...

Embodiment approach 1

[0041] Embodiment 1: If the FDY spinning hot roll is a double hot roll (two hot rolls), then change one of the hot rolls, and install a splitting roll next to the other hot roll, then the first The set of double heat rolls is changed to a set of single heat rolls with splitting rolls. In addition, in order to produce POY at the same time, a grooved godet is installed behind the FDY spinning heat roll to make the POY tow and FDY tow separate for consolidation purposes.

Embodiment approach 2

[0042] Embodiment 2: If the first heat roller group is a single heat roller (one heat roller, one wire splitting roller), then it can be connected to install a grooved godet behind the first group of heat rollers, so that the POY tow and FDY tows are used for merging.

Abstract

The invention designs a blending method and a device for terylene medium-speed blended FDY and POY blended fibers, and includes section transporting and screening, section drying, screw extrusion, melting and spinning, and air blast cooling. The invention is characterized by the following steps: respectively entering POY spinning and FDY spinning after cooling, entering a nozzle for oiling after POY spinning, and then entering a pre-network; entering a tanker for oiling after FDY spinning, entering the pre-network, entering hot-rolling and drafting, enabling POY filaments and FDY filaments to enter into a guiding flute-type draw-off godet for combining and compounding, entering a go-between after compounding, hot-rolling and sizing, and winding and forming after entering a primary network. The blending method for the terylene medium-speed blended ammoniac fibers can produce FDY and POY composite network yarn by the single-stage process, the combined network yarn ITY product produced by the method has stable inner index and quality, little influencing factor, uniform waster-water shrinkage rate, stable chromaticity, and great economic benefit.

Description

technical field [0001] The invention relates to polyester spinning equipment in the field of light industry and textiles, in particular to a method and device for blending polyester medium-speed blended FDY and POY blended fibers. Background technique [0002] From 2007 to 2010, China's chemical fiber industry will enter an upward cycle and usher in a new period of development full of vitality. The chemical fiber industry showed restorative and steady growth throughout the year. In 2007, the "Guiding Opinions on the "Eleventh Five-Year Plan" Development of the Chemical Fiber Industry" issued by the National Law Reform Commission made an in-depth analysis of domestic and foreign environmental changes and industry development trends, and realized the strategic transformation from "quantitative" to "technical" around the chemical fiber industry It further clarifies the guiding ideology of the development of the chemical fiber industry during the "Eleventh Five-Year Plan" perio...
