Embodiment 1

[0048] The improvement of the organic fiber structure, the preparation and application method of the bridging agent are as follows:

[0049] Put 5g of sodium carbonate (30g in total) into 900ml of deionized water with a water temperature of 0°C to 25°C. The water temperature is preferably close to the normal temperature range of 23°C to 25°C. After vigorous stirring, the 30g of sodium carbonate is completely dissolved. The target pH value is 7.5-11, preferably 8.5-10. After that, add 5g-50g of sodium 2,4-diaminobenzenesulfonate in 3 times, preferably 20g-30g, until it is completely dissolved So far, because 2,4-diaminobenzenesulfonate sodium is weakly acidic or close to neutral, so the pH value of the aqueous solution does not change much at this time, then, add 30g~80g of cyanuric chloride (dropping in 3 times), It is best to use 40g to 50g, and use sodium carbonate to control the pH value at 7.5 to 11 before adding cyanuric chloride, preferably 8.5 to 10, and the temperature...

Abstract

A medicament for the improvement and the bridging of organic fiber structure is characterized in that the structural formula is shown in the right formula and the preparation method of the organic fiber structure is characterized in that the preparation method comprises the following steps: dripping alkaline agent in deionized water gradually, adjusting the pH value to 7.5-11, and dripping 2,4,6-trichloro-1,3,5-triazine compound to obtain the medicament. The invention has the advantage that the production process is simple so that the type of the required raw materials is less, and the labor intensity and the production time are reduced; the stability of the medicament is good so that the production cost is reduced; the production time is short, namely only 60-70min under normal conditions so that compared with other preparation methods of which the production time is several hours, the labor cost and the energy cost are reduced and the production efficiency is increased; the preparation method is safe and environmentally friendly, because organic solvent which is harmful to human health and the environment is not used so that the method belongs to environmental processing method.

Description

technical field [0001] The invention belongs to the technical field of finishing after printing and dyeing, and relates to the functional processing of organic fiber structures such as morphological stability and hydrophobicity, in particular to an improvement of organic fiber structures, a bridging agent (hereinafter referred to as the agent of the present invention), and Its preparation and application. Background technique [0002] 2,4-dihalogenated-6-Y-1,3,5-triazine compounds with hydrophilic substituent groups commonly used in the field of functional processing such as morphological stability and hydrophobicity of organic fiber structures , the monomers or mixtures of the following compounds can be cited. [0003] 2,4-Dihalo-6-(3-sulfoanilino)-S-triazine [0004] 2,4-Dihalo-6-(4-sulfoanilino)-S-triazine [0005] 2,4-Dihalo-6-(2-sulfoanilino)-S-triazine [0006] 2,4-Dihalo-6-(2,5-disulfoanilino)-S-triazine [0007] 2,4-Dihalo-6-(3-5-disulfoanilino)-S-triazine [0...
