Description
Technical field
The present invention relates to textile dyestuff field, specially a kind of red cationic dye combination and preparation method thereof.
Background technique
The dye of positive ion (Cationic Dyes) is one kind of textile dyestuff, also known as basic dye and basic dyestuff, is dissolved in
It is in cationic state in water, is mainly used for acrylic fiber dyeing, can also be combined with protein molecule with saline and alkaline, the dye of positive ion
It is water-soluble, it ionizes in aqueous solution, generates the dyestuff of the coloured ion with positive electricity, the cation of dyestuff can be in fabric the
The acidic-group of three monomers in conjunction with and make stock-dye, be acrylic fiber dyeing dedicated dye.
Since the affinity of the dye of positive ion and acrylic fiber is big, it is firmly combined, thus fastness is higher, dyestuff is once upper
After dye, dye molecule is just difficult to easily cause dyeing not from the high region of dyeing concentration to the lower zone migration of dyeing concentration
Equal fault, it is difficult to correct, when using the dye of positive ion, need to be added retarding agents, strict control heating rate, to obtain
Even dyeing effect.
However, some composite cation dyestuffs made of two to three kinds of dye of positive ion blending currently on the market, dyestuff
Between compatibility difference it is larger, this composite cation dyestuff dyeing when, due to the affinity of each dyestuff and fiber exist
Biggish difference, the high dyestuff of affinity fight for more dye seat, and the dyestuff of absorption is more, the concentration difference with fibrous inside with regard to big,
Diffusion is just fast, and dyeing speed is also just fast, and the low dyestuff contention dye seat of affinity is few, and Dye Adsorption is few, with internal concentration with regard to small,
Upper dye is just slow, therefore the dyeing rate of various dyestuffs differs greatly, it is easy to generate dyeing defect, influence the coloured light of product, and dyestuff
Fastness to rubbing, fastness to washing, perspiration fastness it is poor.

It is dried after mixing after profit agent；
S3. the product of step S1 and step S2 are added in batch mixer according to the ratio of 4:1, then dispersing aid is added and is mixed
In material machine；
S4. compound is mixed to form in batch mixer.
Preferably, it is mixed 2-4 hours in batch mixer in step S4.
Preferably, the mass fraction of the dispersing aid is equal to the sum of mass fraction of dyestuff.
The present invention have it is following the utility model has the advantages that
1, the red cationic dye combination is compounded by the five kind dyes of positive ion good to compatibility, and selected
The excellent corresponding weight accounting of five kinds of dyes of positive ion out, so that fiber can fill five kinds of discrepant dyes of positive ion of affinity
Divide and absorb, improves the level-dyeing property of fiber, also reduce the difference of five kinds of dye of positive ion dyeing rates, so that stock-dye is not easy out
Existing dyeing defect, has ensured the bright in color light of product；By further controlling the corresponding weight accounting of five kinds of dyes of positive ion, so that
The performances such as crock fastness, fastness to washing, the perspiration fastness of the red dye of positive ion are significantly increased compared to existing product.
