Embodiment 1

[0038] A kind of FDY light fiber filament dyeing process, comprises the following steps:

[0039] S1, two-for-one twist

[0040] The two-for-one twister is used to twist the FDY bright fiber yarn. The spindle speed of the two-for-one twister is 5000 rpm, the winding speed is 100 m / min, the overfeed speed is 116 m / min, and the yarn twist is 100 twists.

[0041] S2, stereotypes

[0042] Put the two-for-one twisted FDY bright fiber yarn into a setting machine for setting, the setting temperature is 80°C, and the setting time is 12 hours.

[0043] S3, loose tube

[0044] The shaped FDY bright fiber filaments are loosened by a loose winding machine.

[0045] See attached figure 1 , 500gFDY bright light fiber filament loose tube rear outer diameter d1 is 180mm (the outer diameter d2 of barrel core is 63mm), the yarn two ends of winding and barrel core form oblique cone surface, and the inclination of inclined cone surface is H / L= 55 / 58.5 = 1:1.06.

[0046] S4, degreasing

Abstract

The invention provides a dyeing process for FDY bright fiber yarn. The dyeing process includes the following steps of double twisting; shaping; bobbin loosening; unoiling; dyeing; washing; and softening. The twist of double-twisting yarn is 100; the yarn obtained after double twisting is shaped at the temperature of 80 DEG C; and after the yarn is bobbin-loosened to proper tightness, an unoiling agent is added for unoiling, dye and a leveling agent are added to the unoiled yarn for dyeing, then the yarn is washed, and then the yarn is softened. According to the dyeing process for the FDY bright fiber yarn, the treated FDY bright fiber yarn does not easily shrink, can be dyed without being woven, and still has high glossiness after being dyed.

Description

technical field [0001] The invention relates to a polyester fiber dyeing process, in particular to a FDY bright fiber filament dyeing process. Background technique [0002] Polyester fiber can be divided into pre-oriented yarn (POY), fully oriented yarn (FOY), fully drawn yarn (FDY) and stretched textured yarn (DTY) according to different processing types; in modern life, the application of fiber has no Everywhere, the fabric woven by FDY fiber feels smooth and soft, and is often used to weave imitation silk fabrics. In particular, because FDY fiber is a stretched filament that can reflect a certain amount of light, it is widely used in Pennant, stage, jacquard and clothing and other fabric products that require special light effect. [0003] Since the FDY bright fiber is a fully drawn yarn, when it is directly dyed, it will shrink under the dyeing process conditions. In order to avoid the shrinkage, the existing dyeing process is to weave the FDY fiber into a mesh bag and ...
