Description
Technical field
The invention belongs to Masterbatch technical fields, and in particular to a kind of raising level-dyeing property Masterbatch and preparation method thereof.
Background technique
Level-dyeing property refers to dyestuff ability of self level dyeing on the fabric in dyeing course.It is removed by dye molecule and fiber
Outside the impact on physical properties of matrix, also by the system of many factors such as dyeing condition such as temperature, dyeing rate, dyeing assistant used
About.Therefore, mode fabric direct invasion dyed into dyestuff is often difficult to obtain the preferable fabric of level-dyeing property.
In order to improve the level-dyeing property of fabric, application No. is the Chinese invention patent applications of CN 201710599876.6 to disclose
A kind of for improving the Color master batch of terylene ribbon level-dyeing property, which is made of the raw material of following parts by weight: double
15-30 parts of phenol A type liquid-state epoxy resin, 5-10 parts of natural organic dye, 1-5 parts of nonylphenol polyoxyethylene ether, cetanol 0.5-2
Part, 0.5-2 parts of tri (propylene glycol) diacrylate, 0.05-0.5 parts of trihydroxymethylpropanyltri diglycidyl ether, the poly- horse of hydrolysis
Come 0.05-0.5 parts of acid anhydrides.
In use, above-mentioned Color master batch is added in 5 times of weight waters, it is warming up to reflux state insulated and stirred 15min,
Obtain dye liquor；Then the dye liquor is used for the dyeing of terylene ribbon using traditional dyeing.
The Color master batch is disadvantageous in that: only with bisphenol A-type liquid epoxy resin and other auxiliary agents load dye
Material, when use, are still required that dye liquor is made, and this traditional dyeing makes the resin of carried dye and auxiliary agent is still
It is attached to PET fiber surface, is inevitably present traditional dyeing process limitation caused by level-dyeing property；And only adhere to
Fiber surface fuel there is also the problem of dyefastness difference, the dye molecule for having adsorbed on the fabric, which is still easy to happen, to be moved
It moves, can this keep the level-dyeing property of fabric to also proposed very big challenge.
Summary of the invention
Present invention purpose is to provide a kind of raising level-dyeing property Masterbatch and preparation method thereof, uses the Masterbatch energy
Limitation of the traditional dyeing process to dyeing polyester fibers is enough broken through, improves disperse dyes to the level-dyeing property of dyeing polyester fibers.
For achieving the above object, the technical solution of the application is as follows:
A kind of raising level-dyeing property Masterbatch, raw material composition include vector resin and super absorbent resin, the high water absorption
Property resin be graft copolymer that starch or at least two hydrophilic monomer of cellulose graft are formed, the super absorbent resin
Inside it is adsorbed with disperse dyes.
The application adds super absorbent resin to load disperse dyes, by starch and at least two parents in the Masterbatch
It distributed the countless three-dimensional space network structures for being used to accommodate water in super absorbent resin made of aqueous monomers are graft-polymerized,
When immersing the super absorbent resin in the suspension of disperse dyes, disperse dyes can enter these three-dimensional space with dampening
Network structure, after being dried to super absorbent resin, hydrone evaporation, and disperse dyes then and are firmly locked in height
In water-absorbing resins.Polyester fiber is made using the Masterbatch containing this super absorbent resin, disperse dyes can uniformly divide
