Embodiment 1

[0024] ①Polyester fabric to be finished: pure polyester plain weave fabric, its specification is 75D×75D×180×1500.

[0025] ② Preparation of finishing solution: In the preparation, the dosage of organic fluorine three-proofing agent is 100 g / liter, and AG710 is selected. The dosage of the composite nanomaterial dispersion is 0.5 g / liter, and the dispersion system containing nano-zinc oxide and titanium oxide is selected, and the solid content is 25%; the dosage of the soft self-crosslinking adhesive is 6 grams / liter, and the rest is water. Soft water can be used for water. When preparing the finishing liquid, it is best to add water, organic fluorine finishing agent, composite nanomaterial dispersion, and soft self-crosslinking adhesive to the high-level tank for mixing, and stir continuously for 30 minutes, then put into the rolling groove.

[0026] ③ Finish the polyester fabric by padding method: use a uniform pad car, two dipping and two rolling, the dipping temperature of ...

Abstract

A technology for finishing the water-, oil-and dirt repellent polyester fabric includes such steps as preparing the finishing liquid from organofluorine composite nano material dispersed liquid and flexible-type self-crosslinking adhesive, dipping it in the finishing liquid for 0.5-1 min, squeezing, prebaking at 100-110 deg.C for 1-2 min, and baking at 130-180 deg.C for 3-5 min. Its advantages are excellent "three repelling" function, better durability and high washing resistance.

Description

technical field [0001] The invention relates to a water-repellent, oil-repellent and antifouling finishing method for polyester fabrics. Background technique [0002] At present, the following finishing agents are mainly used for fabric waterproofing at home and abroad: paraffin-aluminum soaps, pyridinium quaternary ammonium salts, methylol melamine derivatives, chromium stearate complexes, organic silicon, etc., and their common feature is that they do not reject Oily, not stain-resistant, poor washability. In recent years, fluorine-containing compounds have been gradually used in fabric water repellency, oil repellency and antifouling finishing. Compared with traditional water-repellent agents, it has better water-repellent, oil-repellent, and anti-fouling properties, but the dosage is large, and the anti-fouling effect is not very ideal, and there are durability and The problem of poor washability. Nanotechnology is a new high-tech emerging in t...
