Description
Technical Field
The invention relates to a towel washing process and a detergent.
Background
Washing is a process by which soil is removed from a soiled substrate surface into the media contacted. The various washing processes actually carried out are very complex, including, on a microscopic scale, complex interfacial phenomena between soil-substrate-detergent. The process is closely related to the washing medium, detergent, soil composition, mechanical force during washing, and washing temperature. The commonly used washing medium is water, which acts as a solvent in the wash, dissolving soluble soils, dispersing poorly soluble soils, and acting as a medium to transfer other washing forces. The substrate, i.e. the carrier of the soil, is mainly a variety of fabrics. The conventional washing process is to disperse the soil attached to the substrate into the medium by mechanical force. The first thing that occurs in the washing process is the wetting of the dirt particles and the surface. And then the liquid dirt and the solid dirt are wrapped, emulsified, dispersed and suspended in a medium under the action of the detergent, so that the removal effect is achieved.
The detergent mainly comprises synthetic washing powder, liquid detergent and soap 3. Soap is the most prominent human washing product in the world. In ancient times, people learned that the saponin and some alkaline substances containing active substances in nature are directly adopted for washing, so that the washing activity becomes more efficient and labor-saving, and the clothes after washing are cleaner. The development of synthetic detergents began in 1918 with the alkylation and sulfonation products of naphthalene synthesized in germany and was later replaced by the technology of high pressure hydrogenation reduction of fatty acid esters to fatty alcohols due to the significant cost reduction of fatty alcohols, thereby opening the market for washing and products. The main components of the detergent are active components and auxiliary components, and the detergent has certain detergency. Surfactants are the primary active materials, while those that contribute to the performance of the detergent are a series of auxiliary components in the composition that act as distinct synergies. With the continuous improvement of living standard, people pay more attention to the sustainable development of detergent products. At present, the research of preparing liquid fatty acid potassium soap by using papaya seed oil as a raw material and applying the liquid fatty acid potassium soap to a detergent to improve the washing effect is not found, the preparation conditions and the process of the papaya seed oil fatty acid potassium soap are researched, the papaya seed oil fatty acid potassium soap serving as a surfactant has good detergency when being applied to the detergent, the high-valued utilization of the production byproduct papaya seeds is promoted, and the adverse effect of the existing chemical detergents on the environment can be reduced
The multifunctionalization of detergents is also an urgent need. The material for washing towels and clothes is complex and various, and the selection and use requirements of the detergent meet different requirements and requirements. For example, products with concentrated and super-concentrated formulas in the current market have the characteristics of resource saving and environmental protection, and can be used for washing and softening the laundry detergent; the laundry detergent has the functions of static resistance, softness, color protection, degerming, hard water resistance, low foam and the like; the sterilization laundry detergent added with components such as bacteriostasis, deodorization and the like, such as sterilization bacteriostat containing sea salt or natural plant extracts and the like can remove common escherichia coli and staphylococcus aureus on clothes, and is suitable for being used by special crowds.
The towel washing process has the advantages of good detergency, high washing efficiency, green and environment-friendly used detergent and good antibacterial effect.
