Description
The present invention relates to a kind of method of utilizing reducible (vattable) dyeing or printing cellulosic fibrous material, (vat dye) should be understood to comprise reducing dye and SULPHUR DYES at reducible dyes described in the literary composition of the present invention.
It is known utilizing reducing dye dyeing or printing fiber textile material.In order to make this water-insoluble reducing dye have required substantivity, promptly in order to be fixed on this textile material, must at first it be changed into direct water-soluble leuco (leuco) form by reduction (vatting), develop to dye pigment once more by oxidizing process then.
In the dyeing of denim, normally used dyestuff is indigo, and the fiber that uses is 100% cotton.In the one way dying operation, have only about procrypsis of 10 to 20% indigo by fiber absorbs.Because this low degree of exhaustion, utilize indigoly to exhaust the colouring method that dyes processing by batch-type and use not extensive.Thereby common the employing in several flow processs, the i.e. technology of continuous dyeing in several steps.Therefore used the very long machine with 8 to 10 unit, each unit is by the application apparatus that is used to reduce (padding mangles) and ventilative (skying) platform formation of being used to subsequently reoxidize.This make usually yarn with the form of cotton rope or wire harness or the method that dyes with the form of warp thread piece in, by flooding in short-term and carry out mud jacking and bipseudoindoxyl dye after oxidation uses reduction stain from a plurality of a large amount of dye liquors in the ventilative platform in centre repeatedly.
Reduction stain all is under the room temperature in all cases, so padding mangles can not heat.Realized indigo dyeing by such mode, wherein the outer fiber that in fact has only yarn is by dye coloring, and those fiber itselfs also only are to be colored (ring dyes) very shallow hierarchy.Polishing by granite-wash is handled is particularly ground off at the exposure portion place of the jean product of making dyestuff.As a result, need on the market to have obtained see easily do old process, in the family expenses washing process, can proceed this process equally.
Two types machine be generally used for the dyeing warp thread of denim: hank-dyeing machine or rope dyeing machine, wherein warp thread ties together and forms a plurality of wire harness or cotton rope (rope dyeing); Perhaps open width dyeing machine, wherein warp thread is with the mode of open width dye (beam dyeing).Integrated starching process in the dyeing.Afterwards, with weave yarn after this dyeing of undyed raw weft.
In the indigo tinctorial yield of about pH 11.5 scopes far above in pH 12.5 to 13 scopes.In addition, be diffused into indigo more in the fiber in higher pH scope, this has reduced the required skin effect of denim.Thereby the ring that is to obtain tinctorial yield preferably with the indigo advantage that dyes and has an expection in the scope of pH about 11.5 dyes effect.Yet in industrial indigo dyeing machine, not every dye bath all has the alkaline metering units of pH monitoring, thereby monitoring pH is a problem.
Except traditional blue denim, people also need to comprise the denim fabric of other tone, and can present " granite-wash " effect of expection equally.Yet with indigo different, most of reducing dyes have obviously higher compatibility to fiber under its procrypsis form, thereby obviously higher degree of exhaustion is arranged, and make it in fact can not produce the yarn that ring dyes under the condition of indigo dyeing.Thereby under the indigo dyeing condition of routine, can not use this reducing dye.
It is a kind of with the dyeing of cotton material be printed as the economical method of indigo and non-indigo tone that the problem that the present invention is directed to is to provide, and this method especially can be carried out on the machine at general type under the condition of indigo dyeing, and can obtain the spectral color of broad.Described product dyed thereby also should present level-dyeing property, high tinctorial strength and the color density of height, and dyes effect as the ring of classical denim article characteristics.
