Example Embodiment

[0083] Example 1:

[0084] 1. Preparation of copolymer:

[0085] A. Preparation of the initiator aqueous solution: 1.5 grams of potassium persulfate and 20 grams of water are added to make the initiator aqueous solution;

[0086] B. Synthesis of copolymer: Add 3.5g of N-vinylpyrrolidone, 7.2g of maleic anhydride, 5.0g of itaconic acid, 22g of acrylamide, 50g of water, 6.1g of acrylic acid and 1.5g of methacrylic acid into a 500ml four-necked flask. , Warm up to 50-70℃, keep for 30-60 minutes to fully dissolve the raw materials, add 1.2g sodium bisulfite and 7g initiator aqueous solution, the reactant will naturally rise to 70-90℃, maintain 80-90℃ slowly respectively Add the remaining potassium persulfate aqueous solution and the remaining mixture of 10 g of acrylic acid, 2 g of methacrylic acid and 50 g of water. After the addition, the reactant is heated to 80-100°C for 3-5 hours; after the reaction is completed, the temperature is lowered to below 40°C, Adjust the pH value of th...

Abstract

The invention discloses an environmental-friendly type foamless anti-staining detergent, a preparing method and an application thereof which includes a multipolymer and an alkaline-resisting chelated dispersion stabilizer efficiently without phosphorus. Each component has weight percentage as follows: multipolymer 40-70%, alkaline-resisting chelated dispersion stabilizer efficiently without phosphorus 5-10%, polyvinylpyrrolidone PVP-30 0-3%, polyvinylpyrrolidone PVP-15 0-2%, other water. The detergent is mainly used for cleaning treatment after dyeing or printing of fabric to remove floating color of fabric thoroughly, accordingly, can remove floating color, prevent staining and increase the fabric color fixing degree.

Description

field of invention [0001] The present invention relates to a cleaning agent and its preparation method and application, more particularly to an environment-friendly non-foaming anti-contamination cleaning agent and its preparation method and application. Background technique [0002] According to the statistics of the National Bureau of Statistics, the national output of printing and dyeing cloth from January to July in 2008 totaled 27.926 billion meters; the total export volume of the six categories of printing and dyeing cloth was 6.864 billion meters. billion meters. Such a large number of fabrics need to be dyed or printed, and the dyed or printed fabrics must be washed in the printing and dyeing factory, otherwise the floating color on the fiber (that is, the dye or pigment that is not combined with the fiber) and the dye or pigment that is not firmly combined with the fiber Will seriously affect and reduce the color fastness of fabric, make these fabrics fade in a lar...
