Embodiment approach

[0031] The third embodiment of the present invention provides a method for utilizing the dyed liquid after dyeing. The dyed liquid after dyeing is used as a recycled dye, and fabric fibers are added to the recycled dye for dyeing; the dyed liquid after dyeing is dyed as described above. The remaining liquid material after method dyeing.

[0032] Specifically, the dyeing method is reciprocating oscillation, and the oscillation speed is 100-200 r / min.

[0033] Specifically, the dyed dye solution produced by the post-dyeing dye solution utilization method can still be further processed by the post-dye dye solution utilization method.

[0034] In order to enable those skilled in the art to understand the technical solutions of the present invention more clearly, the technical solutions of the present invention will be described in detail below with reference to specific embodiments and comparative examples.

Embodiment 1

[0037] A method for dyeing cotton fibers with novel dyes produced by the polymerization of catechol and polyethyleneimine, comprising the following steps:

[0038] (1) The cotton fiber was added to deionized water at a liquor ratio of 1:50 (o.w.f.) for washing, and the washing time was 30 min. After washing, after drying at 60 °C for 2 h, the pretreated fabric fibers were obtained, such as figure 1 a shown.

[0039] (2) Take 4 pieces of pretreated fabric fibers with a size of 5 × 10 cm and add them to 200 mL of polyphenolamine dye solution containing 5.05 mL of polyethyleneimine and 1 g of catechol for polymerization at 35 °C for 24 h, and at 35 °C Dyeing for 20min. After being fully washed with deionized water and dried at 60°C for 2 hours, dyed fabric fibers were obtained, such as figure 2 a shown.

Embodiment 2

[0041]A method for dyeing mulberry silk with a novel dye produced by the polymerization of catechol and polyethyleneimine, comprising the following steps:

[0042] (1) Add mulberry silk to 0.3 g / L sodium carbonate solution at a liquor ratio of 1:50 (o.w.f.) for washing, and the washing time is 30 min. After washing and drying at room temperature for 2 hours, the pretreated fabric fibers were obtained, such as figure 1 b shown.

[0043] (2) Take 4 pieces of pretreated fabric fibers with a size of 5 × 10 cm and add them to 200 mL of polyphenolamine dye solution containing 5.05 mL of polyethyleneimine and 1 g of catechol for polymerization at 35 °C for 24 h, and at 35 °C Dyeing for 20min. After being fully washed with deionized water and dried at room temperature for 2 hours, dyed fabric fibers are obtained, such as figure 2 b shown.

Abstract

The invention belongs to the technical field of textile printing and dyeing, and relates to application of a polyphenol amine dye in printing and dyeing fabric fibers and a dyeing method. The preparation method comprises the following steps: carrying out oxidative polymerization reaction on polyethyleneimine and catechol in water in the presence of oxygen to obtain the polyphenol amine dye, and adding fabric fibers into the polyphenol amine dye for dyeing. According to the present invention, with the application of the polyphenol amine dye to dyeing, the printing and dyeing auxiliary agent can be omitted, the fresh water consumption can be reduced, the color fastness can be improved, and the printed and dyed material can have the antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to an application and a dyeing method for printing and dyeing fabric fibers based on polyphenolamine dyes. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] The phenomenon of washing fading or bleed-through of traditional dyes due to low color fastness. In addition, a large number of printing and dyeing auxiliaries and fresh water are used in the traditional fiber printing and dyeing process, which not only increases the production cost and process complexity, but also makes the printing and dyeing wastewater often high in salt and high alkalinity, which is diffi...
