Description
Technical field
The present invention relates to the synthetic leather colouring method in light industry field, specifically a kind of method that improves deep dyeing for island superfine fiber PU synthetic leather base cloth dispersion dyes.
Background technology
Island superfine fiber PU synthetic leather base cloth is to be base material with island superfine fiber (sea component is a polyester, and the island component is a polyamide) non-weaving cloth, produces to make after the polyurethane high molecule impregnation process.
Because the base cloth fiber is a superfine polyamide fiber, therefore have the essential characteristic of superfine fibre dyeing: dyeing speed is fast, and level-dyeing property is poor, and engrain is poor, and dyefastness is low, poor reproducibility.Superfine fibre is different to the affinity of dyestuff with polyurethane simultaneously, also can influence the uniformity of dyeing.Therefore island superfine fiber PU synthetic leather base cloth dyeing difficulty is very big, how to improve its dyeability, improves engrain and dyefastness, is the subject matter that numerous colourists need to be resolved hurrily always.
Contain more nonpolar hydrocarbon chain link in the superfine polyamide fiber strand, can use disperse dyeing.Polyurethane is generally interacted by binary or polynary organic isocyanate and polyol compound and gets, and its structure is made up of soft chain segment and hard segment between polyamide and polyester.The soft chain segment part-structure is loose, is the main positions of dying on the DISPERSE DYES.Therefore, island superfine fiber PU synthetic leather base cloth can be used disperse dyeing.
But DISPERSE DYES is the non-ionic dye of a class slightly solubility, does not have-SO
3H, water soluble groups such as-COOH, and have-OH-NH
2,-CN ,-NO
2And substituting group such as halogen atom, their solubility in water is extremely limited, only dissolves a small amount of dyestuff in the solution and just can reach capacity rapidly.And being dyestuff, one of most important condition of dying fiber on the dyestuff must in dye liquor, dissolve, have only the dyestuff of unimolecule shape could adsorb upward fiber rapidly, and diffuse into fibrous inside, so there is the problem of engrain difference in the dyeing of island superfine fiber PU synthetic leather base cloth dispersion dyes.
Need to seek a kind of new method and new technology that improves deep dyeing for island superfine fiber PU synthetic leather base cloth dispersion dyes at present in a hurry.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defective of the conventional disperse dyeing of island superfine fiber PU synthetic leather base cloth, and a kind of new colouring method and technology are provided, and improves the engrain of island superfine fiber PU synthetic leather base cloth dispersion dyes dyeing.
For addressing the above problem, a kind of method that improves deep dyeing for island superfine fiber PU synthetic leather base cloth dispersion dyes provided by the present invention, it is characterized in that the dyeing prescription is: dye strength 3%owf, vinyl ester monomer concentration 4～10% (v/v), catalyst amount 4～8% (v/v), penetrating agent JFC consumption 1g/L, peregal consumption 2g/L; bath raio 30: 1, pH=5～5.5;
Processing step comprises: add levelling agent and dyestuff under the room temperature, and, be warmed up to 40 ℃ with 3 ℃/min speed with acetic acid and sodium acetate buffer solution adjusting pH value, be warmed up to 100 ℃ with 1 ℃/min speed again, be incubated 60 minutes, cool to 60 ℃ with 1 ℃/min speed then.
In this method owing to adopt the vinyl ester monomer as dyeing auxiliaries, in island superfine fiber PU synthetic leather base cloth dispersion dyes dyeing course, the vinyl ester monomer mainly plays following two aspect effects: during (1) dyeing, the vinyl ester monomer is adsorbed on fiber surface, formation is dissolved with the vinyl ester monomer and the oligomer liquid film of DISPERSE DYES, the dyestuff dissolubility is fine in liquid film, improve the concentration gradient of dyestuff inside and outside fiber, also can accelerate the dyeing rate of dyestuff and the speed that fiber is advanced in transfer; (2) the molecular proportion dye molecule of vinyl ester monomer is little, the diffusion rate height, enter fibrous inside prior to dye diffusion, fiber is played plasticization, increase the mobility of fiber macromolecular chain, make fibre structure lax, thus the increased fiber free volume, vitrification point is reduced, improve dyestuff in intrastitial diffusion rate.Therefore, in the DISPERSE DYES dye bath, add certain density vinyl ester monomer, can significantly improve dye uptake and K/S value.Compare with conventional disperse dyeing process, the present invention also has the following advantages: engrain is good and dyeing temperature is low, can reach Color preferably in 100 ℃ of dyeing of normal pressure, and existing staining technique generally all will reach 140 ℃, therefore energy resource consumption is low, more energy-conservation.
Following examples help to understand the present invention.
