The reason of poor color fastness of polyester dyed by dyeing machine

Author:Huaxia TechnologyHits:Published time:2020-01-08
Often are often faced with polyester dyeing machine production or containing polyester fabric dyeing cloth color after the cylinder is normal, but after finishing of next working procedure in the light, is a drop in local color flower porphyritic, strip and fastness etc. Phenomenon, this kind of problem not serious can re-work, not a serious, to the production of the dye house can influence the quality of delivery.

For customers with high requirements on polyester color fastness, in actual production, the dye factory cannot achieve the ideal color fastness after dyeing by high temperature and high pressure dyeing machine, through reduction cleaning, and then through high temperature setting. Because polyester with disperse dyes dyeing after heat transfer phenomenon is the key to lead to the above problems, heat transference is a kind of performance, disperse dye widespread refers to after finishing at high temperature to finalize the design by dry or humid air through fiber capillary effect part of the dye from fiber to fiber surface internal migration, due to the accumulation of the dye on the fiber surface and redistribution, the existence of the additives and surfactants including the remaining on the cloth will strengthen its produce.

Due to the heat transfer is mainly related to the structure of the dye itself, and the size of disperse dyes with different structure its heat transference also differ, the difference between each other is bigger also, especially when high temperature to finalize the design the finishing so when using silicone oil, antistatic, because its contain a certain amount of surfactant, and when these additives on the cloth uneven adsorption include cloth PH not divide evenly, can produce the so-called color flower, color change, washing, stained with color fastness to decline, such as friction, a series of problems, such as, this phenomenon is often characterized by one or several coexist, which brings to the dyeing quality is difficult to overcome the hidden danger and harm.
