Description
Technical Field
The invention belongs to the field of animal fiber cleaning, and particularly relates to a cleaning agent composition for cleaning animal fibers, and a preparation method and application thereof.
Background
Animal fibers (e.g., wool) are important raw materials for the production of wool. As a natural animal fiber, it is contaminated with animal glandular secretions, excretions, and other contaminants (e.g., soil, plant debris, etc.) during its growth. Therefore, before textile processing, the original animal fibers (raw hair) are cleaned and decontaminated to remove grease, sweat and other organic or inorganic impurities attached to the animal fibers. The animal fibers to be cleaned are usually immersed in water by a water washing method, and water-soluble contaminants are removed by mechanical agitation or ultrasound. However, the water-insoluble greasy contaminants on the fibers usually require the addition of a detergent in water to remove them to some extent from the fibers. Therefore, the fiber cleaning agent plays an important role in the processes of penetration, emulsification, dispersion and deoiling in the cleaning process of the animal fibers. The cleaning ability of the cleaning agent directly influences the characteristics of fiber whiteness, looseness and the like after washing, and has great influence on subsequent processing of the fiber and product quality. Therefore, the development of the animal fiber cleaning agent with higher cleaning efficiency has important practical application significance.
CN110343579A discloses a chemical cleaning agent for an air preheater, which comprises sodium dodecyl benzene sulfonate, sodium alkyl sulfosuccinate, polyoxyethylene alkyl ether, alkylbenzene sulfonate, polyamide, organic silicon, trisodium phosphate and sodium hydroxide, can clean the air preheater on line, does not influence the operation of the air preheater, and has good cleaning effect, high descaling rate and high practicability. However, the cleaning agent cannot be directly used for cleaning animal fur.
CN109811352A discloses a rapid penetration cleaning agent, comprising: sulfuric acid, an acid washing auxiliary agent, a rapid penetrating agent, a low-foaming emulsifier and a corrosion inhibitor. The cleaning agent can quickly permeate into workpieces with deep holes, small holes and slits within 3 seconds, emulsifies and clears away pollutants, greatly shortens the time of cleaning procedures, has a low-foam function, cannot clamp bubbles in the deep holes, the small holes and the slits, is more convenient and quicker to rinse, and is particularly suitable for cleaning holes of automatic lines and complex workpieces. However, the cleaning agent cannot be directly used for cleaning animal fur.
CN102660392A discloses a wool detergent, which comprises natural nonionic surfactant, aliphatic polyol with 2-8 carbon atoms, inorganic ammonium salt stabilizer and organic salt preservative. The nonionic surfactant is tea saponin, soapberry saponin, alkyl polyglycoside or sorbitan ester. The residual fat rate of the wool washed by the detergent is below 0.5 percent, but the method needs repeated washing and is time-consuming and labor-consuming.
Based on the above studies, it can be seen that there are certain limitations to the development of a cleanser for animal skins, and further optimization of the composition of the cleanser for animal skins is required. Therefore, the cleaning agent is provided, the cleaning efficiency of the cleaning agent on animal fibers is improved, and the cleaning agent has great practical significance to the field of textile processing.
