Abstract
The invention discloses a dyeing method of a cone yarn vat dye. In the steps of adding an reducing agent, the reducing agent is added for two to three times; when the reducing agent is added for two times, the addition amount of the reducing agent is less than that of the first time, and the addition amount for the second time accounts for 70% to 90% of that of the first time; and when the reducing agent is added for three times, the addition amount of the reducing agent for the second time is less than that of the first time and the third time, respectively, the addition amount of the reducing agent of the second time accounts for 65%-85% of that of the first time, and the addition amount of the reducing agent of the third time accounts for 75%-95% of that of the first time. The dyeing method of the cone yarn vat dye can solve the problems that the flower cores and the flower layers of the cone yarn can not be totally dyed or uniformly dyed. The re-dyeing rate is reduced from more than 50% to less than 1.8%. The water-resistance color fastness and the unlubricated friction color fastness can reach above grade 3.
Description
Technical field
The present invention relates to a kind of colouring method of reducing dye, particularly relate to a kind of colouring method of bobbin yarn vat dye.
Background technology
At present, when utilizing cone dyeing equipment to use reducing dye that the tube yarn is dyeed,, and then be reduced into the original color and luster of dyestuff through oxidation because reducing dye will become leuco compound to dying on the yarn through reducing dyes when dying on carrying out.In these a series of complex processes, a tube yarn flower core, layer flower very easily occur, dye saturating or tube yarn about problems, especially dye strength such as inconsistent during greater than 5%o.w.f (concentration of the relative fabric of dyestuff), also the problem that dyefastness does not pass a test can appear.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of colouring method of bobbin yarn vat dye, solves a tube yarn flower core, layer flower, dyes saturating or about problem such as inconsistent.
For solving the problems of the technologies described above, the invention provides a kind of colouring method of bobbin yarn vat dye, wherein, add in the step at reductant, reductant divides 2～3 addings.
The colouring method of above-mentioned bobbin yarn vat dye wherein, adds for 2 times fashionablely when reductant divides, and described second time, addition was less than addition for the first time, and addition be 70～90% (weight) of the addition first time for the second time; Add fashionable when reductant divides 3 times, described second time, addition was less than for the first time and addition for the third time, addition is primary 65-85% (weight) for the second time, addition is primary 75-95% (weight) for the third time, reductant add in batches can make dyestuff not too fast the or reduction strength of reason reduction cause dyeing flower inadequately.
The colouring method of above-mentioned bobbin yarn vat dye, wherein, the distance between the described adjacent cartridges yarn is 5～8.5cm, is beneficial to the circulation of dye liquor, makes yarn fully contact dye liquor.
The colouring method of above-mentioned bobbin yarn vat dye, wherein, the open-work on the cheese dyeing equipment inner core tube is shaped as circle, and is preferred, and the open-work of core pipe is for outwards there being the circular through-hole of chamfering in tube core.Present used core pipe open-work is shaped as rectangle, too big problem can not appear when dying coarse yarn thigh yarn, as 32S/2,21S/2 etc., but dying 21S/1, when 16S/1 or 40S/2 yarn, adopt square open-work can make uneven dyeing, and the suitable open-work that adopts is shaped as circular core pipe, is good with the circular through-hole that chamfering is arranged, and the Circularhole diameter of core inside pipe wall is greater than the Circularhole diameter of core tube wall, it is smooth more that dye liquor is circulated from inside to outside, is beneficial to level dyeing.
The colouring method of above-mentioned bobbin yarn vat dye wherein, after raw yarn is carried out pre-treatment, increases a rewinding step, and tube yarn Internal and external cycle yarn position is changed, and is about to original inner ring and becomes the outer ring, helps the level dyeing of follow-up staining procedure.
The colouring method of bobbin yarn vat dye of the present invention can solve a tin yarn flower core, layer flower, dye saturating or about problem such as inconsistent, return the rate of dying by being reduced to more than 50% below 1.8%, water-fast (fade, staining) COLOR FASTNESS and unlubricated friction COLOR FASTNESS can reach more than 3 grades.
Description of drawings
Fig. 1 is the core pipe schematic diagram in the used cheese dyeing equipment of colouring method preferred embodiment of the present invention;
Fig. 2 is the core pipe schematic diagram in the used cheese dyeing equipment of another preferred embodiment of colouring method of the present invention.
The specific embodiment
Describe the present invention in detail below in conjunction with drawings and Examples.
The technological process that reducing dye dyeing is adopted among the following embodiment is: add dyestuff, caustic soda, reductant → the addings reductant second time → add reductant → washing → oxidation for the third time → soap boiling → washing → oven dry for the first time.
Embodiment 1
The addition of reductant is 65% (weight) of the reductant addition first time for the second time, and the reductant addition is 75% (weight) of the reductant addition first time for the third time, and the distance between the adjacent cartridges yarn is 5cm.
As shown in Figure 1, the open-work 2 on the cheese dyeing equipment core pipe 1 that adopts in the present embodiment is for circular.
