Problems solved by technology

[0002] Fabrics are very popular and used by consumers, but the current fabrics have disadvantages such as poor moisture absorption and air permeability, uncomfortable wearing, and poor friction resistance; and man-made fiber fabrics are improperly used during use, or improperly washed during washing , will cause man-made fiber fabrics to be damaged in different degrees
[0003] With the development of economy and the advancement of science and technology, people have higher and higher requirements for fabrics; it is urgent to modify conventional polyester fibers to improve their additional properties, and to increase their moisture absorption and air permeability by modifying polyester fibers; The fiber mainly improves the moisture absorption and air permeability of polyester fibers by changing the shape of the fiber cross section, fine denier, adding modifiers, etc.; changing the fiber cross section has triangular, trilobal, cross, straight, pentagonal, octagonal, etc. Among them, the cross-section fiber has a larger specific surface area and surface grooves, which can increase the moisture absorption and air permeability effect, and its shape is relatively simple, and the production is convenient; but the special-shaped fiber is easy to form stress concentration, and the fiber strength is lower than that of the circular cross-section fiber. And the friction resistance is poor; but conventional polyester fibers have disadvantages such as poor moisture absorption and air permeability, and uncomfortable wearing

Embodiment 1

[0021] Such as figure 1 As shown, in the preparation method of the pearl fleece breathable fiber described in this example, the pearl functional masterbatch is placed in the masterbatch dryer 1 to dry for 13 hours, the water content of the masterbatch is 28ppm, and the drying temperature of the masterbatch is 130°C. The masterbatch is extruded after melting through the screw extruder 2, and the temperature of each section of the extruder is divided into 277°C, 282°C, 288°C, 292°C, 292°C, 292°C, and then passes through the melt pre-filter 3 The molten masterbatch is sent into the metering injection pump 4 through the delivery pipeline, and the masterbatch melt is sent into the dynamic mixing agitator 10 through the delivery pipeline 7 to mix with the polyester melt after the metering. The speed of the dynamic mixing agitator 10 is 60r / min. The mixed polyester melt is further mixed uniformly through the static mixer 11; the uniformly mixed polyester melt is passed through the po...

Embodiment 2

[0025] Such as figure 1 As shown, in the preparation method of the pearl fleece breathable fiber described in this example, the pearl functional masterbatch is placed in the masterbatch dryer 1 to dry for 14 hours, the water content of the masterbatch is 29ppm, and the drying temperature of the masterbatch is 130°C. The masterbatch is extruded after being melted by the screw extruder 2, and the temperature of each section of the extruder is divided into 278°C, 283°C, 289°C, 293°C, 293°C, 293°C, and then passed through the melt pre-filter 3 The molten masterbatch is sent into the metering injection pump 4 through the delivery pipeline, and the masterbatch melt is sent into the dynamic mixing agitator 10 through the delivery pipeline 7 to mix with the polyester melt after the metering, and the speed of the dynamic mixing agitator 10 is 63r / min. The mixed polyester melt is further mixed uniformly through the static mixer 11; the uniformly mixed polyester melt is passed through th...

Abstract

The invention discloses a production method of a polyester fiber, and aims to provide a preparation method of a bright velvet breathable fiber. The bright velvet breathable fiber contains pearl powder, has beauty skin care functions, and is smooth and cool in hand feeling, hygroscopic, breathable and comfortable to wear. By the preparation method of the bright velvet breathable fiber, the breathability and the wearing comfort of the polyester fiber are improved, pearl function master batches are added by the aid of online flexible adding technology when polyester melt is conveyed, spinning is performed by the aid of profiled spinnerets in the spinning process, natural pearls are milled to form the pearl powder, so that the pearl polyester fiber does not contain chemical hazardous substances, the ultrafine pearl powder enters the fiber by mixing the ultrafine pearl powder with the polyester melt in a spinning manner, and the ultrafine pearl powder and the fiber-forming polymer are closely combined. The bright velvet breathable fiber has permanency, cannot fall off after long-term washing and wearing, contacts with skin for a long time and has beauty skin care, skin whitening and ultraviolet resistant functions.
