Description

Technical Field

[0001] The invention relates to the technical field of washing, in particular to an anti-color-crossing washing tablet and a preparation process thereof. Background Art

[0002] With the progress of society and the improvement of living standards, people have higher and higher requirements for the cleaning, maintenance and environmental protection of clothes. In recent years, the use of color absorbing sheets and laundry detergents has become more and more common, especially in daily life. In order to prevent the occurrence of color transfer during the washing process, many people choose to use color absorbing sheets. However, the existing color absorbing sheets and laundry detergents are usually used separately, and cannot provide effective anti-color transfer and cleaning functions at the same time. In addition, the existing color absorbing sheets have problems such as unstable color absorption effect and limited color absorption capacity. Especially when washing multiple pieces of clothing or mixing dark and light-colored clothing, clothing color migration is prone to occur, affecting the quality and appearance of the clothing.

[0003] At the same time, when traveling, working, or needing to clean clothes quickly, it is neither convenient nor practical to carry color absorbing tablets and laundry detergent separately. In order to meet the growing market demand, a comprehensive washing product that can combine the characteristics of color absorption, cleaning, and portability is urgently needed.

[0004] Therefore, developing a new type of washing tablet that can effectively prevent color bleeding, has a strong cleaning function, and is easy to carry has become an important direction for solving the problems of the prior art.

[0005] Contents of the invention.

[0006] In view of this, the object of the present invention is to provide an anti-color transfer washing tablet and a preparation process thereof to solve the above-mentioned problems.

[0007] The present invention relates to an anti-color-bleeding washing tablet, belonging to the field of washing technology, and in particular to a washing tablet and a preparation process thereof that can effectively prevent the occurrence of color-bleeding on clothes during the washing process. Existing laundry products such as color-absorbing tablets and laundry detergents are usually used alone, and cannot provide the comprehensive effects of cleaning, protection and anti-color-bleeding at the same time, and are inconvenient to carry when going out. In order to solve the above problems, the present invention provides an innovative anti-color-bleeding washing tablet, which combines a color-absorbing fiber carrier and a strong laundry detergent. Through a specific material ratio and preparation process, it can not only effectively absorb dyes and impurities in water to prevent color-bleeding on clothes, but also provide efficient cleaning and clothing protection functions.

[0008] The anti-color transfer washing sheet of the present invention uses color-absorbing cationic fiber, ES fiber and polyester fiber or viscose fiber layer as a carrier, and has good color-absorbing and strength characteristics. The fiber web is reinforced by a hydroentanglement process to ensure the tight entanglement between the fibers, and further improve the stability of the carrier. With a special strong laundry detergent, the anti-color transfer washing sheet of the present invention can achieve color absorption and cleaning during the washing process, and is easy to use and carry, and is very suitable for home and travel use.

[0009] Beneficial effects of the present invention: The anti-color cross-contamination effect is remarkable: the color-absorbing fiber in the present invention has a very strong dye adsorption capacity, and can effectively absorb the dyes released during the washing process of clothes, thereby preventing clothes of different colors from contaminating each other.

[0010] Strong cleaning ability: The strong laundry detergent in the formula contains a variety of enzyme preparations and surfactants, which can penetrate deep into clothing fibers, break down stains, and ensure the cleanliness and softness of clothes.

[0011] Strong environmental protection: The fiber materials and laundry detergent used in the present invention are all environmentally friendly ingredients. After use, the washing tablets can be naturally degraded to reduce environmental pollution, which meets the needs of green and sustainable development.

[0012] Easy to carry: The anti-color transfer washing tablets are lightweight and can be packaged individually. When using, just put them in the washing machine or hand wash water. The operation is simple and it is especially suitable for travelers or office workers.

[0013] Durability and versatility: Each anti-color transfer detergent sheet can handle 6 to 8 pieces of clothing, has a long service life, and has both anti-color transfer and cleaning functions, further improving the practicality and economy of the product. BRIEF DESCRIPTION OF THE DRAWINGS
