Problems solved by technology

Therefore, when the polyester fiber is not in a puffed state, the surface crystal layer is not loose, and it is relieved, the reducing agent cannot effectively contact and decompose the disperse dye molecules that have penetrated into the fiber, resulting in an ineffective stripping effect. , can only play the role of removing floating color on the fiber surface

Embodiment 1

[0015] In this embodiment, the swelling agent is polyethylene glycol, the penetrating agent is JFC, the stripping agent is acetic acid solution, and the dispersant is NNO. Add 40 parts by mass of polyethylene glycol and 1 part by mass of penetrant JFC to 100 parts by mass of polyester fabric, stir and preheat at 40°C to fully wet the polyester fabric with polyethylene glycol, and then at a rate of 2°C / min Raise the temperature to 100°C, treat for 30 minutes, take it out; mix 60 parts by mass of acetic acid solution, 1 part by mass of penetrant JFC and 0.1 part by mass of dispersant NNO, stir to make it evenly dispersed, and make a stripping solution; take it out after swelling treatment Add the polyester fabric into the stripping solution, preheat and stir at 40°C, then raise the temperature to 100°C at a rate of 2°C / min, treat for 30 minutes, cool down to 60°C, and take out the polyester fabric. Put the polyester fabric after the color stripping treatment into boiling water w...

Embodiment 2

[0017] In this embodiment, cyclohexanone is selected as the swelling agent, JFC is selected as the penetrating agent, glacial acetic acid solution is selected as the stripping agent, and NNO is selected as the dispersant. Add 80 parts by mass of cyclohexanone and 1 part by mass of penetrant JFC to 100 parts by mass of polyester fabric, stir and preheat at 50°C to fully wet the polyester fabric with cyclohexanone, and then increase the temperature at a rate of 2°C / min To 120°C, treat for 30 minutes, take it out; mix 100 parts by mass of glacial acetic acid solution, 1 part by mass of penetrant JFC and 0.1 part by mass of dispersant NNO, stir to make it evenly dispersed, and make a stripping solution; take it out after swelling treatment Add the polyester fabric into the stripping solution, preheat and stir at 60°C, then raise the temperature to 100°C at a rate of 2°C / min, treat for 30 minutes, cool down to 60°C, and take out the polyester fabric. Put the polyester fabric after ...

Embodiment 3

[0019] In this embodiment, polyethylene glycol is selected as the swelling agent, penetrant SF is selected as the penetrant, glacial acetic acid solution is selected as the stripping agent, and NNO is selected as the dispersant. Add 200 parts by mass of polyethylene glycol and 1 part by mass of penetrant SF to 100 parts by mass of polyester fabric, stir and preheat at 60°C to make the polyethylene glycol fully wet the polyester fabric, and then at a rate of 3°C / min Heat up to 120°C, treat for 30 minutes, take it out; mix 100 parts by mass of glacial acetic acid solution, 2 parts by mass of penetrant SF and 0.5 parts by mass of dispersant NNO, stir to make it evenly dispersed, and make a stripping solution; The polyester fabric taken out was added to the stripping solution, preheated and stirred at 40°C, then heated to 110°C at a rate of 5°C / min, treated for 50 minutes, and cooled to 60°C to take out the polyester fabric. Put the polyester fabric after the color stripping treat...

Abstract

The invention relates to a stripping treatment method for removing colour on terylene textile, belonging to the spinning and dyeing processing field. The stripping method includes that the terylene textile is treated by sweller firstly, then the terylene textile after sweller treatment is subject to heat processing by adopting stripping solution containing main stripping agent, penetrant and dispersant, so as to weaken the combination between terylene fibre molecule and dispersed dye molecule, thus dispersed dye is stripped from the terylene textile. Compared with the traditional stripping treatment technology, the technical scheme of the invention is applicable to stripping treatment on dispersed dye with strong binding force on the terylene textile, dyes in different structure types can be stripped from the terylene textile, the terylene textile returns to original colour, thus being convenient for redying or for repeated prilling and degrading to realize cycle use.

Description

technical field [0001] The invention relates to a color stripping treatment method for removing color on polyester fabric, which belongs to the field of textile printing and dyeing processing. Background technique [0002] Polyester is produced by collecting and chemically polymerizing waste gas from petroleum refining. It has extremely poor degradability, and its waste fibers pose a serious threat to environmental pollution. On the one hand, with the increasing demand of chemical fiber products, dyes have been greatly developed in quantity and variety, and their pollution to the environment will become more and more serious. my country is a big country of textile production and consumption, and a large amount of textile waste and waste textiles are produced every day. Recycling these textile wastes not only has great economic significance in terms of saving raw materials and reducing costs, but also has great significance in improving the level of resource utilization, env...
