Embodiment 1

[0027] A method for finishing anti-pollution textiles, comprising the following steps:

[0028] 1) Corona treatment is performed on the cotton cloth: it is carried out under the condition of a mixed gas with a volume ratio of oxygen and nitrogen of 2:8, and the treatment is carried out under the condition of 6kV for 6s.

[0029] 2) Add 1 mol of butyl titanate, 0.4 mol of oxalic acid and 3 mol of sodium dihydrogen phosphate into a mixed solvent composed of 3L of ethanol and 18L of water, seal and heat at 160°C for 36 hours, cool to room temperature, and put the cotton cloth treated in step 1) Immerse in it, adopt the process of two immersion and two dehydration, each immersion for 10 minutes; each dehydration control liquid retention rate is 80%, and dry at 60°C for 3 hours;

[0030] 3) Mix FG-410 water-repellent and oil-repellent treatment agent with water at a concentration of 30g / L. Immerse the cotton cloth treated in step 2) into it, and adopt a two-immersion and two-dehydr...

Embodiment 2

[0032] A method for finishing anti-pollution textiles, comprising the following steps:

[0033] 1) Corona treatment is performed on the cotton cloth: it is carried out under the condition of a mixed gas with a volume ratio of oxygen and nitrogen of 2:8, and the treatment is carried out under the condition of 8kV for 6s.

[0034] 2) Add 1 mol of butyl titanate, 0.3 mol of oxalic acid and 2 mol of sodium dihydrogen phosphate into a mixed solvent composed of 2L of ethanol and 14L of water, seal and heat at 140°C for 30 hours, cool to room temperature, and put the cotton cloth treated in step 1) Immerse in it, adopt the process of two immersion and two dehydration, each immersion for 12 minutes; each dehydration control liquid retention rate is 100%, and dry at 60°C for 3 hours;

[0035] 3) FG-410 water-repellent and oil-repellent treatment agent is mixed with water, the concentration is 40g / L, and the cotton cloth treated in step 2) is immersed in it, and the process of two immer...

Abstract

The invention provides an anti-fouling textile finishing method. The method includes steps: subjecting textiles to corona treatment; adding butyl titanate, oxalic acid and sodium dihydrogen phosphateinto an ethyl alcohol and water mixed solvent, performing hermetical heating reaction, cooling to the room temperature, soaking the treated textiles, adopting a twice-soaking twice-dewatering process,and drying; soaking the treated textiles into water-repellent oil-repellent finishing agent solution, adopting a twice-soaking twice-dewatering process, drying and baking. Compared with the prior art, the anti-fouling textile finishing method has advantages that great water and oil repelling effects are achieved, fouling is prevented, high firmness of a waterproof layer and high light degradation efficiency are realized, and the self-cleaning performance is improved; in addition, a preparation method is simple and low in cost.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a method for finishing anti-pollution textiles. Background technique [0002] With the progress of society and the development of science and technology, the single function of materials can no longer meet people's needs. For example, for textile materials, people not only require basic functions such as warmth retention and comfort, but also put forward new requirements for functionalities such as self-cleaning and anti-pollution. [0003] Research on finishing methods with self-cleaning and anti-pollution textiles has broad application prospects. Contents of the invention [0004] The purpose of the present invention is to provide a finishing method for anti-pollution textiles. First, the textiles are corona-treated, then photocatalytically modified, and then impregnated with a water- and oil-repellent treatment agent. The treated textiles are water- and oil-repellent, an...
