Embodiment 1

[0009] The production method of the colored polyester yarn of the present embodiment comprises the following steps: using white polyester pre-oriented yarn, cationic fuel dyeable polyester and black polyester pre-oriented yarn as raw materials, passing through the yarn guide and the first roller in sequence , first heat box, twister, second roller, network nozzle, third roller, oiling roller, stretching and winding forming, said white polyester pre-oriented yarn, cationic fuel dyeable polyester and black silk polyester The mass ratio of pre-oriented filaments is 2:2:3. Said drawing speed is 200-300m / min; said drawing ratio is 1.53-1.56.

[0010] The polyester colored yarn produced in this example has a strength of 4.3cN / dtex, an elongation of 1.7%, a crimp shrinkage of 18%, and a crimp stability of 80%.

Abstract

The invention provides a production method of a colored polyester yarn. The production method adopting three raw yarns including white polyester pre-oriented yarns, cation fuel dyeable polyester and black polyester pre-oriented yarns as materials comprises the following steps of: enabling the materials to pass through a yarn guide, a first roller, a first hot box, a twister, a second roller, a mesh spray nozzle, a third roller and an oil applying roller in sequence; and stretching, rolling and forming the materials, wherein the weight ratio of the white polyester pre-oriented yarns to the cation fuel dyeable polyester to the black polyester pre-oriented yarns is 2:2:3. The production method of the colored polyester yarn provided by the invention has the following technical effects that the produced colored polyester yarn is good in performance, stable in quality, provided with three mixed colors, high in product linear density and strength and good in rolling performance and stability, so that the fabric is rich in elasticity and good in hand feeling.

Description

technical field [0001] The invention relates to a production method of colored polyester yarn, which belongs to the technical field of chemical fibers. Background technique [0002] Polyester has very good chemical fiber properties, including good dyeability. The existing production method of colored polyester yarn is mainly made of white polyester yarn. This method takes a long time, has high loss, pollutes the environment, and costs high. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a production method of colored polyester yarn. [0004] The production method of polyester colored yarn of the present invention comprises the following steps: using three kinds of raw yarns of white polyester pre-oriented yarn, cationic fuel dyeable polyester and black polyester pre-oriented yarn as raw materials, passing through the yarn guide, the first roller, The first hot box, twister, second roll...
