Description

Technical Field

[0001] The present invention relates to the technical field of detergents, in particular to an easy detergent and a preparation method and application thereof. Background Art

[0002] Textiles often become stained with oil, dust, and other stains during use, making them difficult to clean or even prone to re-contamination during washing. This shortcoming can be addressed through stain-releasing finishing, which can improve the quality of the product. Stain-releasing properties make it easier to remove stains (water-based and oil-based) from fabrics during subsequent washing or wiping. Stain-releasing agents are the primary means of achieving this.

[0003] Existing stain removal treatment agents can be divided into two categories: hydrophilic and waterproof. Hydrophilic stain removal agents are mostly used in skin-friendly products such as towels, T-shirts, and underwear, and have advantages such as good hygroscopicity and antistatic properties. Waterproof stain removal agents are mostly used in home textiles, outdoor textiles, and car interiors, which can make textile products have the protective effects of being waterproof, oil-proof, and easy to remove stains, and the products have high added value. Existing waterproof stain removal products mostly use fluorine-containing resin matrices. Not only do they have the problem of perfluorinated compound pollution, but hydrophobic and oleophobic stain removal agent emulsions with fluorine-containing polyurethane structures also have the disadvantages of high cost and mediocre stain removal effect. Hydrophobic and oleophobic stain removal agent aqueous solutions with fluorine-containing acrylate structures have the disadvantages of high cost, hard feel, and poor washing resistance. Therefore, there is an urgent need to develop a stain removal treatment agent with excellent hydrophobicity, softness, and environmental protection. Summary of the Invention
