Abstract
The invention relates to application of disperse dye microcapsules in leather, which is characterized in that the disperse dye microcapsules are used for coating finishing on the leather. The application comprises the following steps: 1) preparing color paste by preparing 5-10% of disperse dye microcapsules, 75-88% of resin, 2-5% of a filler and 5-10% of a solvent, adding the disperse dye microcapsules in a mixture of the resin and the solvent, and stirring to disperse the disperse dye microcapsules in the resin uniformly; 2) coating by uniformly coating the prepared color paste on the leather, and drying at a temperature of 100-120 DEG C; and 3) ironing by performing low ironing on the dried leather at a temperature of 80-130 DEG C for 1-5 seconds. The leather processed by the method provided by the invention has surface colors with large contrast before and after the processing; the colors are well proportioned and bright, the fixing force for dyes is strong, and water washing at a high temperature does not cause fading; the leather is wear-resistant, and has texture and three-dimensional appearance very similar to those of suede fabric; and the coating method is simple and easy to operate, and can be quickly put into production.
Description
Technical field
The present invention relates to the top finish technical field, be specifically related to a kind of microcapsule disperse dye carries out top finish on leather method.
Background technology
Its core of microcapsule disperse dye is solid, shaped DISPERSE DYES filter cakes; In processing or use; Through microcapsules rupture under the conditional stimulus such as external pressure, friction, pH value, enzyme, temperature, light, the material that wherein is wrapped slowly is discharged in the needed surrounding environment for use.
Leather receives people's great kindness over the past thousands of years always deeply, and still early stage leather is leted others have a look at brownish black always, and color and kind are all very dull.Nowadays, the Along with people's growth in the living standard, to leather aspects such as color, cortex require increasingly high.Leather itself has been broken through the warming limitation of its resisting cold, has concurrently and modifies and beautification function, develops towards personalized, fashion-orientation direction.
The coatings applications of microcapsule disperse dye on leather do not appeared in the newspapers; Patent of invention " a kind of microcapsule disperse dyeing process for superfine fibre synthetic leather " (application number: 200710048049.4) introduced the dyeing of a kind of microcapsule disperse dye on superfine fibre synthetic leather; Dyeing and coating process have essential distinction, and the effect difference of final products is also very big.。
Summary of the invention
The object of the present invention is to provide a kind of microcapsule disperse dye on leather, to carry out the method for top finish.Contrast before and after the leather surface color after top finish, the flatiron is very big, in picturesque disorder, and color is beautiful, bright-coloured, and the dyestuff pull-out capacity is strong, and high-temperature water can't is washed off look, rub resistance.
The present invention provides the application of a kind of microcapsule disperse dye on leather, it is characterized in that microcapsule disperse dye is used for the top finish on the leather, is divided into following steps:
1) mill base preparation: each constituent mass percentage: microcapsule disperse dye 5～10%, resin 75%～88%, filler 2～5%, solvent 5～10%; Microcapsule disperse dye is joined in the mixture of resin and solvent; Stir, microcapsule disperse dye is dispersed in the resin;
2) coating: the above-mentioned mill base for preparing evenly is coated on the leather 100～120 ℃ of oven dry;
3) flatiron: the leather after the above-mentioned oven dry is carried out low temperature flatiron, 80～130 ℃ of temperature, 1～5 second time.
Common process is adopted in the preparation of microcapsule disperse dye: after DISPERSE DYES filter cake, emulsifying agent, the mixed high speed shear of water; Drip the wall material while stirring and carry out wall building; The reaction a period of time, discharging, the oven dry and get.Emulsifying agent is selected TX-10 for use, Tween 80, and class of department 80, or carry out them composite.
Above-mentioned described resin effect is that viscosity is big as medium bonding between microcapsule disperse dye and the leather, and is water insoluble, can solidify fast during low temperature drying.The resin that uses among the present invention is one or both in polyurethane, polyamide, polyacrylic acid, methacrylic acid, the methyl acrylate.Mill base that its ingredients constitute is prepared (mass fraction) 75%～88%, satisfied is 78～86%.
Above-mentioned described solvent action is that resin viscosity is bigger, add solvent after, the viscosity of resin can reduce, and is made into behind the mill base easily blade coating on leather, and under the temperature of appointment, can flash baking.The solvent that uses among the present invention is in N ' dinethylformamide, toluene, xylene, hexane, the cyclohexane one or both.Mill base that its ingredients constitute is prepared (mass fraction) 5～10%, satisfied is 5～7%.
Above-mentioned described filler effect is a feel of improving leather, and behind the use filler, the feel of leather has promoted the quality of leather greatly just as suede nap.The filler that uses among the present invention is in titanium dioxide, dispersing agent NNO, talcum powder, calcium carbonate, attapulgite, the paraffin one or both.Mill base that its ingredients constitute is prepared (mass fraction) 2～5%, satisfied is 2～3%.
The technique effect of inventive method is: the leather of producing is in picturesque disorder, and color is beautiful, bright-coloured, and the dyestuff pull-out capacity is strong, and high-temperature water can't is washed off look, rub resistance; And texture and cubic appearance with very strong suede nap; Method is simple, and is easy to operate, can put into production rapidly
