Embodiment 1

[0046] Tenthylcycloikoxysiloxane dyeing solution is stained with cellulose fibers.

[0047] Each 5 g of the surfactant Aeo-3 and the surfactant were orthodontically octanol, stirred to uniform, formulated auxiliary solution. 2.5 g of the formulated auxiliary solution was taken, the decaptoliosiloxane solution was added to 100 mL, stirred to uniform, formulated into a decaptoliolioxide solution containing auxiliary agent. 0.06 g (3% OMF) cocoa pigments were dissolved at 1 ml (50% OMF), 2 mL (100% OMF), 6 mL (300% OMF), 8ml (400% OMF), respectively. In 10 ml (500% OMF) water, it is formulated into a high concentration of a high-concentration can be capable cholatin natural dye solution containing different moisture content. Subsequently, it is subsequently added to 40 ml of decimal decaptoliosiloxane solution to 40 mL, stirred to uniform. The preparation of a decaptogen-dyled solution containing different moisture content was completed, and the absorbance of the absorbance was detec...

[0053] Tenthylcycloikoxysiloxane dyeing solution is stained with cellulose fibers.

[0054] Each 5 g of the surfactant Aeo-3 and the surfactant were orthodontically octanol, stirred to uniform, formulated auxiliary solution. 2.5 g of the formulated auxiliary solution was taken, the decaptoliosiloxane solution was added to 100 mL, stirred to uniform, formulated into a decaptoliolioxide solution containing auxiliary agent. 0.06 g (3% OMF) cocoa pigment was taken in water of 2 ml (100% OMF), formulated into a high-concentration cocoa cholatin natural dye solution, and then added to the formulated auxiliary decay-based ring five Silicone solution to 40 ml, stirred to uniform, prepared to complete the decimal ring five silicone dye, and detect its absorbance, ie, precipitance, pre-stained liquid absorbance, remembient A0.

[0055] 2 g of cotton cloth was subjected to 40 mL (bath ratios 1:20) of Tenthylcyclo-stained liquid, respectively, at 80 ° C for 10 min, 20 min, 30 min, 40 min, and...

Embodiment 3

[0060] Tenthylcycloikoxysiloxane dyeing solution is stained with cellulose fibers.

[0061] Each 5 g of the surfactant Aeo-3 and the surfactant were orthodontically octanol, stirred to uniform, formulated auxiliary solution. 2.5 g of the formulated auxiliary solution was taken, the decaptoliosiloxane solution was added to 100 mL, stirred to uniform, formulated into a decaptoliolioxide solution containing auxiliary agent. 0.06 g (3% OMF) cocoa pigment was taken in water of 2 ml (100% OMF), formulated into a high-concentration cocoa cholatin natural dye solution, and then added to the formulated auxiliary decay-based ring five Silicone solution to 40 ml, stirred to uniform, prepared to complete the decimal ring five silicone dye, and detect its absorbance, ie, precipitance, pre-stained liquid absorbance, remembient A0.

[0062] Take 2G cotton cloth, which is immersed in a decarnamethylcyclo-dye of 40 ml (bath ratios 1:20), from 60 ° C, 70 ° C, 80 ° C, 90 ° C, 100 ° C for 30 min, dye...

Abstract

The invention discloses a method for improving the dyeing rate of cellulose fibers dyed with natural dyes, which comprises the following steps: 1) preparing a decamethylcyclopentasiloxane solution with auxiliary agents; 2) preparing a dyeing solution; 3) completing Preparation of decamethylcyclopentasiloxane dyeing solution; 4) complete dyeing to obtain dyed matter; 5) prepare color fixing solution; 6) complete preparation of decamethylcyclopentasiloxane color fixing solution; 7) complete fixing color, the invention effectively increases the dye uptake of natural dyes in cellulose fibers, improves the utilization rate of dyes, and improves the color fastness to washing. At the same time, decamethylcyclopentasiloxane is an environmentally friendly solvent, and can be recycled and recycled. The dyeing and color fixing method of the invention uses very little water, which effectively reduces the water consumption in the dyeing process, saves resources, saves costs, and improves product value.

Description

Technical field [0001] The present invention relates to the field of natural dye staining, and more particularly to a method of improving the luggage rate of native dye chromophore. Background technique [0002] Natural dye dye cellulose fibers generally have low dyes, which is mainly due to natural dyes difficult to adsorb and fix them on cellulose fibers. Thus, in order to increase the upper dye rate of the natural dye on the cellulose fiber, the dyeing technique of the precursor, the same media or the post-media can be introduced into the metal ion, and the dye is increased and the water resistance fastness of the chromosome. . Natural dyes are generally difficult to havecense cellulose fibers are mainly determined by their molecular structure. Natural dyes have poor affinity to cellulose fibers, resulting in less dye amounts on the dye on the dye, which requires additional metal ions to be complexed, and more dyes are added to fibers, and Has good water resistance fastness. H...
