Problems solved by technology

However, the levelness of this method is not satisfactory
At the same time, due to the padding method, the water consumption is high and the modification efficiency is poor; the liquid carrying rate of the polyester fabric after treatment is as high as 60-80%, and the subsequent drying energy consumption is relatively large
[0007] However, for polyester fabrics, the polyester fabric treatment liquid and its application method in the above-mentioned existing inkjet printing technology are still unsatisfactory.

Embodiment 1

[0066] β-cyclodextrin and 2,3-epoxypropyltrimethylammonium chloride were incubated at 65°C for 5 hours in the presence of sodium hydroxide; among them, β-cyclodextrin and 2,3-epoxypropyltrimethyl Ammonium chloride and sodium hydroxide are respectively 10 parts by weight, 2.5 parts by weight and 1 part by weight. Then add hydrochloric acid until the pH is less than 8, cool down to 5°C, and precipitate out. Disperse the precipitate in water, heat it to 85°C to dissolve it, and then drop it into isopropanol to obtain a precipitate; the volume ratio of water and isopropanol is 1:10. The above dissolution-precipitation process was repeated three times, and vacuum-dried to obtain the quaternary ammonium salt modified cyclodextrin. The IR spectrum shows that the -OH stretching vibration absorption peak on β-cyclodextrin is changed from 3325cm -1 Blue shift about 70-80cm -1 .

[0071] β-cyclodextrin and 2,3-epoxypropyltrimethylammonium chloride were incubated at 65°C for 5 hours in the presence of sodium hydroxide; among them, β-cyclodextrin and 2,3-epoxypropyltrimethyl Ammonium chloride and sodium hydroxide are respectively 10 parts by weight, 5 parts by weight and 1 part by weight. Then add hydrochloric acid until the pH is less than 8, cool down to 5°C, and precipitate out. Disperse the precipitate in water, heat it to 85°C to dissolve it, and then drop it into isopropanol to obtain a precipitate; the volume ratio of water and isopropanol is 1:12. The above dissolution-precipitation process was repeated three times, and vacuum-dried to obtain the quaternary ammonium salt modified cyclodextrin. The IR spectrum shows that the -OH stretching vibration absorption peak on β-cyclodextrin is changed from 3325cm -1 Blue shift about 70-80cm -1 .

Abstract

The invention discloses a polyester fabric treatment liquid for printing and a use method thereof, which comprises a quaternary ammonium salt modified cyclodextrin. In addition, the method for using the treatment liquid and the polyester fabric obtained therefrom are also disclosed. Through the specific polyester fabric treatment liquid, combined with the improvement of the treatment process and the selection of process parameters, the clarity, level dyeing and color depth of polyester fabric inkjet printing have been greatly improved; at the same time, the color fastness to rubbing and washing color of polyester fabrics have been improved. fastness. Compared with the existing method, the liquid carrying rate of the treated polyester fabric is as low as 10‑35%, which greatly reduces the subsequent drying energy consumption.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a polyester fabric treatment solution for digital inkjet printing and a use method thereof. Background technique [0002] With the improvement of economic and living standards, people's requirements for textile and clothing gradually tend to be individualized and diversified; at the same time, my country's safety, ecological and environmental regulations are becoming more and more stringent. People are constantly looking for printing and dyeing technologies that meet modern requirements such as environmental protection, energy saving, and water saving. As a new printing technology, digital inkjet printing technology has been continuously promoted and applied. Digital inkjet printing technology is to print the ink directly onto the fabric by the inkjet printing system after the required printing pattern is processed by the computer to form a pattern. Diff...
