Embodiment 1

[0020] The dyeing method of embodiment 1 polyester cheese

[0021] The yarn count of 150D is selected for the polyester package yarn of this embodiment, and the dyeing method includes steps: gray yarn (paper tube) → loose yarn (plastic straight tube) → scouring at 130°C for 30 minutes, dehydration → loose yarn overturning → dyeing → post-treatment → Dehydration → Winding.

Embodiment 2

[0022] The dyeing method of embodiment 2 polyester cheese

[0023] The yarn count of polyester cheese in this embodiment is 100D, and the dyeing method includes steps: gray yarn (paper tube) → loose yarn (plastic straight tube) → scouring at 100°C for 20 minutes, dehydration → loose yarn overturning → dyeing → post-treatment → Dehydration → Winding.

Abstract

The invention discloses a polyester cheese dyeing method which comprises the steps of grey yarn preparation, yarn loosening, dyeing, postprocessing, dehydration and spooling. The polyester cheese dyeing method further comprises the steps of boiling off and dehydration and yarn loosening and tipping after the yarn loosening step but before the dyeing step. The polyester cheese dyeing method is different from a traditional polyester yarn production process, and the purposes of yarn shrinkage at different degrees and oil removal through preprocessing can be achieved by adopting boiling off and tipping and then cooperating with appropriate boiling-off temperature and time. The tipping is performed after boiling off and dehydration, the process actions of repeatedly performing the preprocessing are omitted, it is ensured that no shrinkage situation occurs in the high-temperature dyeing process, and blocked dye penetration is avoided. By the adoption of the polyester cheese dyeing method, the problems of dyeing defects, chromatic aberration and the like in polyester yarn dyeing and the dyeing rate are obviously improved, the color stability is good, and the demands for production and dyeing of different polyester yarns can be met.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and more specifically, the invention relates to a dyeing method of polyester cheese cheese. Background technique [0002] In recent years, as more and more customers have recognized the unique wearability of polyester yarn, the demand for polyester yarn package dyeing products has increased accordingly. Due to the huge polyester yarn production market, various types of polyester yarns, and differences in the elasticity of different yarn counts, how to respond to consumers' requirements for color and quality has brought challenges to polyester cheese dyeing. [0003] The dyeing of polyester cheese is carried out on the high temperature and high pressure cheese dyeing machine. Polyester fiber is a hydrophobic synthetic fiber. The dyeing is generally dyed with disperse dyes. The polyester molecules are arranged relatively tightly, and there are only small gaps in the fiber. When ...
