Described reduction clearing step be by dyeing after yarn enter in reduction cleaning liquid, and clean 30min at 100 DEG C, wherein the prescription of reduction cleaning liquid is: glacial acetic acid 1.5g/L; Reduction cleaner 1.5g/L; Antistatic additive prescription 1.0g/L.
In described metal step, be that 0.33 ~ 0.39g/cm3 is wound on stainless steel spring pipe by Polyester Yarns with rolling density.
Described pre-treatment step, for immerse in light alkali solution by yarn, processes 20min under 100 DEG C of conditions, and adds soaping agent 1g/L and to deoil process.
Beneficial effect: a kind of Polyester Yarns dyeing that the present invention discloses, because the speed of DISPERSE DYES dyeing rate is directly proportional to the height of dyeing temperature, by carrying out temperature-gradient method process to dyeing, the utilization rate of dyestuff is greatly enhanced, and make Polyester Yarns to realize level dyeing, and dyefastness is high, dyestuff can also recycle.
Detailed description of the invention
Below in conjunction with specific embodiment, technology contents of the present invention is described in detail:
Disclosed a kind of Polyester Yarns dyeing, its technological process is: raw yarn enters factory-metal-chamfering-dress cage-enter dye vat-pre-treatment-washing-dyestuff interpolation-dyeing-draining-wash water-reduction cleaning-wash water-acetic acid neutralization-wash water-dehydration-oven dry; It is in staining jar, add the dye well auxiliary agent dissolved that wherein said dyestuff adds; Described dyeing be the Polyester Yarns that pre-treatment is completed enter successively be warming up to 70 DEG C with 1 ~ 2 DEG C/min in staining jar after level dyeing 10min, and then level dyeing 10min after being warming up to 100 DEG C with 1 ~ 2 DEG C/min, be finally warming up to 130 DEG C of insulation 45 ~ 60min with 1 ~ 2 DEG C/min.
In described metal step, be that 0.33 ~ 0.39g/cm3 is wound on stainless steel spring pipe by Polyester Yarns with rolling density, the first-selected stainless steel spring pipe of metal, its advantage is that effectively to penetrate area large especially, highly beneficial to acquisition level dyeing, and for the control of rolling density, if winding is too tight, dye liquor difficulty penetrates very thick layer, because contact dyestuff obtain very little, colour cast is shallow causes look flower or the dye such as chromosphere defect in local, and winding is too loose, and cylinder yarn is easily out of shape and comes off, cause ravellings, be difficult to machine.
Dyeing pre-treatment mainly removes its commensal to natural fabric.Concerning then remove the synthetic fiber such as terylene its artificial after add the grease, dust, pigment etc. that " impurity " comprise finish and the contamination added in spinning or weaving process.Wherein, it should be noted that finish most.Containing lubricant, emulsifying agent, antistatic additive etc. in finish.Apply finish to the spinning of the synthetic fiber such as terylene, to weave be necessary.If but dyeing and finishing add man-hour must by finish eccysis contaminate before do not wash, dye with these finishes, finish can terylene surface formed one deck " blocking film ", hinder dyestuff evenly spread to fibrous inside, permeate.Thus, easily cause colouring irregular, produce the dye defects such as look flower, color spot.And, loose colour also can be made to increase, affect COLOR FASTNESS.If dyeing pretreatment process is not in place, the finish on fiber is removed irregular, just may produce cloud form look flower; If in dyeing course, dye dispersion poor stability in dye liquor, there is coacervation, these finishes can be combined with the aggregation of dyestuff again, attach product dyed thereby and produce color spot, in the present invention, pre-treatment is mainly reinforcement purified treatment, is immersed by yarn in light alkali solution, under 100 DEG C of conditions, process 20min, and add soaping agent 1g/L and to deoil process.
