Description

Technical Field

[0001] The invention belongs to the technical field of detergents, and in particular relates to a formula of a laundry fiber wrapping material with a high surfactant content and a preparation method thereof. Background Art

[0002] In daily life, we often use various types of washing products to clean clothes. Among them, conventional laundry detergents are often powerless and the cleaning effect is unsatisfactory due to their relatively low content of surfactants and usually contain no or only a small amount of detergent aids when facing some stubborn stains. Although concentrated laundry detergents and laundry beads have a higher surfactant content and can provide stronger cleaning power, due to the limitations of their dosage forms, they cannot add a large amount of chelating agents and other detergent aids. As a result, when faced with some specific heavy oil dirt, colored dirt and granular dirt, their performance is often unsatisfactory and the cleaning effect is relatively weak. As for laundry powder, although it performs relatively well in terms of cleaning power, its content of surfactants is low and it contains a large amount of inorganic salt additives, which causes greater damage to clothes during the washing process and easily leads to wear and deformation of clothing fibers.

[0115] Performance Testing

[0116] The laundry fiber wrappings prepared in Examples 1-3 and Comparative Examples 1-15 were tested for detergency according to standard GB / T13174-2021. The test results are shown in Table 1 below.

[0117] Table 1

[0118]

[0119]

[0120] As can be seen from Table 1, the laundry fiber wrappings prepared in Examples 1-3 of the present application have excellent washing and decontamination effects;

[0121] In Comparative Example 1, the bentonite was not modified, and in Comparative Example 2, the fluorine-containing titanium dioxide was not doped, which would lead to a decrease in the adsorption of surfactants, green chelating agents, anti-redeposition agents, detergent aids, etc., resulting in a decrease in the decontamination effect of the prepared laundry fiber wrapping;

[0122] It can be seen from Comparative Examples 3-7 that the present application can significantly improve the decontamination effect through the synergistic effect of the various anionic surfactants added. Sodium dodecyl sulfate has good decontamination ability and good solubility, and can effectively remove stains. Sodium α-olefin sulfonate can increase the decontamination strength. Sodium cocoate can improve the overall performance of the detergent and increase the affinity of the detergent for grease. Sodium lauryl polyoxyethylene ether sulfate has good emulsifying properties and can help disperse grease in water and increase the cleaning power of the detergent. Sodium fatty acid methyl ester sulfonate can have an auxiliary synergistic effect with sodium dodecyl sulfate to improve the decontamination efficiency. The mixed anionic surfactant can reduce the surface tension of water, so that water can better penetrate into the stains, separate the stains from the fiber surface, and make grease stains easier to be washed away by water. Through these synergistic effects, the mixed anionic surfactant can significantly improve the decontamination ability of the detergent;

[0123] It can be seen from Comparative Examples 8-10 that the present application adds a variety of nonionic surfactants, and through the synergistic effect between fatty alcohol polyoxyethylene ether, fatty alcohol alkoxy compound and alkyl glycoside, the fatty alcohol polyoxyethylene ether has a good solubilizing ability, can disperse the stains in water to form a stable emulsion, so that it is easier to be washed away by water, the fatty alcohol alkoxy compound has good interfacial activity, can reduce the interfacial tension between water and oil, so that the oil stains are more easily surrounded and removed by water molecules, and can penetrate into the interior of the fiber to dissolve or disperse stubborn stains, the alkyl glycoside can penetrate the fiber, and at the same time has a good dispersing ability, can remove water-soluble stains such as protein and starch, the complementary decontamination ability between fatty alcohol polyoxyethylene ether, fatty alcohol alkoxy compound and alkyl glycoside, each of which works synergistically for different types of stains, increases the contact area between the stain and water, facilitates removal, improves the solubility of the stain in water, facilitates washing, penetrates into the interior of the fiber, effectively removes stubborn stains, and enhances the overall performance of the detergent;

[0124] It can be seen from Comparative Examples 11-15 that the present application adds a variety of biological enzymes, and through the synergistic effect of protease, lipase, amylase, cellulase, and pectinase, specifically, during the washing process, the addition of protease can decompose protein into smaller peptide chains and amino acids, lipase can decompose fat into glycerol and fatty acids, amylase can decompose starch into maltose and dextrin, cellulase can decompose cellulose to make it fluffy, pectinase can decompose pectin and destroy the cell wall structure, so that the stains are easier to be washed away by water. By adding a variety of enzymes, multiple types of stains can be targeted at the same time to improve the comprehensiveness of stain removal. After the protease decomposes the protein, the amino acids produced can be used as an emulsifier for lipase to help remove grease. The glucose produced by the amylase decomposing starch can be further used by microorganisms. The low molecular weight substances produced by the enzyme decomposition of stains usually have higher water solubility and are therefore easier to be washed away by water. The catalytic action of the biological enzyme is mild and will not damage the fiber structure of the clothes. It is suitable for various fabrics. The multi-enzyme combination not only improves the stain removal effect, but also extends the service life of the clothes.
