[0030] In the following, in conjunction with examples, the technical solutions of a phosphorus- and nitrogen-free scouring agent and its preparation and use methods related to the present invention will be further described in detail.

[0031] In the present invention, all the raw materials used are conventionally used and can be purchased from the market. In the present invention, unless otherwise specified, all amounts, percentages and parts are weight units.

[0032] An embodiment of the present invention provides a phosphorus- and nitrogen-free scouring agent, which is composed as follows in weight percentage:

[0033] Isomerized fatty alcohol polyoxyethylene ether 8.2%;

[0034] Fatty alcohol polyoxyethylene polyoxypropylene ether 14.8%;

[0035] Rosin polyoxyethylene ether carboxylate 26.6%;

[0036] Sodium secondary alkyl sulfonate 15.4%;

[0037] Water 35.0%.

[0038] Further, the preparation method of the phosphorus- and nitrogen-free scouring agent includes the following steps:

[0039] Add the melted isomeric fatty alcohol polyoxyethylene ether and fatty alcohol polyoxyethylene polyoxypropylene ether in order in the reaction kettle according to weight percentage, turn on the stirrer, and fully stir for 30-50 minutes;

[0040] Then add the rosin polyoxyethylene ether carboxylate and sodium secondary alkyl sulfonate in sequence, and heat to 50-60°C while stirring;

[0041] Slowly add the measured pure water (the addition will be completed within 30-60 minutes), and continue to keep stirring at 50-60°C for 1-2 hours;

[0042] After fully stirring and uniformly, the temperature is lowered to 30-40° C. and the material is filtered out to obtain the phosphorus- and nitrogen-free scouring agent.

[0043] In an implementation of the use of the phosphorus- and nitrogen-free scouring agent, the fabric involved is a pure cotton yarn card 20X16 fabric, the process is a cold pile process, and the materials involved include:

[0044] Caustic soda 50g/L;

[0045] The phosphorus- and nitrogen-free scouring agent 15g/L;

[0046] Hydrogen peroxide (100%) 30g/L;

[0047] Oxygen bleaching stabilizer 15g/L;

[0048] Among them, two dip and two rolling at room temperature, the rolling reduction rate is 100%.

[0049] Further, it also includes the following steps:

[0050] Stack at room temperature for 16~24 hours-----wash with hot water (95℃) for 3 times----wash with cold water for 2 times----dry to regain moisture.

[0051] Test the gross effect and whiteness: gross effect (cm/30min): 14.8; whiteness: 80.5%.

[0052] The present invention relates to a phosphorus- and nitrogen-free scouring agent and a preparation and use method thereof. The phosphorus- and nitrogen-free scouring agent adopts an environmentally friendly formula that does not contain nitrogen, phosphorus and APEO, and has high scouring efficiency during use. , The whiteness is good, making it an environmentally friendly scouring agent with high processing efficiency, and has a good market application prospect.

[0053] The technical scope of the present invention is not limited to the content in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should belong to Within the scope of the present invention.
