Example

[0079] Comparative Example 8

[0080] Using the same cloth as in Example 8, the dyed and dried cloth does not need to be treated with the C fiber modifier. Take Asahi GUARD E-082 treated with fluorine-based waterproofing agent at the same 60g / L, and put other additives under the same conditions for waterproofing. However, due to the results of the prior confirmation experiment, the texture of the material has a rough feeling and does not meet the characteristics of the material, so the bath needs to be adjusted, and amino silicone oil (manufactured by Nikka Chemical Co., Ltd.) 3g / L should be added to the padding bath. . The extrusion rate remains unchanged, and the processing is completed under the same process. The results are shown in Table 7.

Abstract

The invention relates to a method of enabling fiber structures to be continuously durable and hydrophobic, which belongs to the technical field of printing and dyeing. By means of the reactant mixture of 2,6-dichloro-4-hydroxy-1,3,5-triazine sodium and sodium diaminobenzene sulfonate, use of impurities such as PFOA (perfluorooctanoic acid), PFOS (perfluorooctane sulfonate) and the like is avoided successfully, and fluorine waterproof agent compound with six or less carbon atoms is better in continuous endurance and waterproofness than existing prevailing fluorine waterproof agents with 8 or more carbon atoms, wherein the impurities with 8 or more carbon atoms are mixed in production of the fluorine waterproof agent and are harmful to human health. In addition, the mixture of the two reactants containing hydrophilic replacement groups is used with the fluorine waterproof agent with 6 or less carbon atoms, so that occurrence probability of static electricity is reduced greatly, and the problem of dust attachment can be solved favorably.

Description

technical field [0001] The present invention relates to a method for making fiber structures enduring and durable hydrophobicity, in particular to a mixed reactant of 2.6-dichloro-4-hydroxyl-1.3.5-triazine sodium salt and sodium diaminobenzenesulfonate. Heat treatment, let the -COOH group and -SO in the fluorine-based waterproofing agent 3 The H group and the acrylate group of the substrate undergo an ion reaction, thereby chemically immobilizing the structure of the fiber-the reactant-fluorine-based compound-the reactant-fiber, and obtain a fiber structure with durable waterproof, oil-proof, and stain-proof properties It belongs to the technical field of printing and dyeing. Background technique [0002] In the past, if a durable waterproofing process was to be performed on a fibrous structure, a fluorine-based waterproofing agent must be used, and this fluorine-based waterproofing agent must have a CF group composed of a long chain of 8 or more carbon atoms. And in order...
