Abstract
The invention provides a method for producing a microdenier nylon 66 stretch yarn. The method comprises the following steps of selecting nylon 66 slices as raw material, sequentially delivering the nylon 66 slices into a drying tower, a screw extruder, a melt distributing pipe, a spinning box, a metering pump and an assembly, carrying out side air blowing, oil applying, stretching, coiling and elasticizing, and finally obtaining the microdenier nylon 66 stretch yarn, wherein the drying temperature is 90 DEG C, the temperature of the spinning box is 295 DEG C, the air speed of the side air blowing is 0.28m / s, the air temperature is 20 DEG C, the coiling speed is 4500m / min, the stretching speed is 800m / min, and the stretching times is 1.25. The method for producing the microdenier nylon 66 stretch yarn has the technical effects that the quality of a product made by the produced microdenier nylon 66 stretch yarn is stable, the linear density CV (coefficient of variation) is 0.9%, the breaking strength is 4.38cN / dtex, and the elongation at break is 35%.
Description
technical field [0001] The invention relates to a production method of fine-denier nylon 66 elastic yarn, which belongs to the technical field of chemical fibers. Background technique [0002] Nylon 66 is a synthetic fiber with excellent performance and wide application. It is widely used in socks and underwear because of its good elasticity and wear resistance. In addition, due to its molecular structure, nylon 66 has better elasticity and wear resistance than nylon 6. . [0003] There is no fine-denier nylon 66 stretch yarn production method suitable for popularization in the prior art. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a production method of fine-denier nylon 66 stretch yarn. [0005] The production method of the fine-denier nylon 66 stretch yarn of the present invention comprises the following steps: selecting nylon 66 slices as raw material, passing through drying to...
