Description
Technical Field
The invention belongs to the field of animal fiber cleaning, and particularly relates to an animal fiber cleaning agent composition suitable for low-temperature use, 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 fiber to be cleaned is 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.
However, the common cleaning agent in the market has the characteristics of low cleaning efficiency, high pour point, easy gelation at low temperature (less than 5 ℃), poor solubility and the like, brings great inconvenience to processing equipment and processes, and greatly increases the process cost of low-temperature processing and use. In cold regions with low air temperature, especially in winter, has become a major factor that restricts its application. Therefore, the development of the animal fiber cleaning agent with higher cleaning efficiency and better low-temperature (<5 ℃) usability has important environmental protection significance and practical application significance.
CN103666870A discloses a wool cleaning agent, which comprises urea peroxide, sodium polyphosphate, sodium carbonate, sodium sulfate, sodium ethylene diamine tetracetate, sodium carboxymethylcellulose, fatty alcohol-polyoxyethylene ether and fatty acid methyl ester sodium sulfonate. The wool cleaning agent can effectively remove dirt in wool and improve the quality of the wool, but the cleaning agent is not suitable for being used at low temperature.
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 wool washed by the detergent is below 0.5 percent, but the method needs repeated washing, is time-consuming and labor-consuming, and is not suitable for low-temperature use.
Based on the above research, it can be seen that there is a certain limitation in the development of a cleaning agent for animal fur in a low temperature environment, and the components of the cleaning agent need to be further optimized. Therefore, the cleaning agent is provided, the cleaning efficiency of the cleaning agent on the animal fibers in a low-temperature environment is improved, and the cleaning agent has great practical significance to the field of textile processing.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an animal fiber cleaning agent composition suitable for low-temperature use, and a preparation method and application thereof. The animal fiber cleaning agent composition can be used for preparing animal hair cleaning agents, animal leather cleaning agents and animal fiber fabric cleaning agents, the obtained cleaning agents can be used in a low-temperature environment, and the cleaning efficiency of dirt (such as grease) and impurities in animal fibers is remarkably improved.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides an animal fiber cleanser composition suitable for use at low temperatures, the animal fiber cleanser composition suitable for use at low temperatures comprising a nonionic surfactant, the nonionic surfactant comprising, by mass percent, 10-75% (e.g., may be 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, etc.) of a first nonionic surfactant and 25-90% (e.g., may be 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, etc.) of a second nonionic surfactant.
The first nonionic surfactant comprises a linear fatty alcohol polyoxyethylene ether nonionic surfactant, and the second nonionic surfactant comprises a branched chain heterogeneous fatty secondary alcohol polyoxyethylene ether nonionic surfactant.
Other point values within the above range can be selected, and are not described in detail herein.
The term "suitable for low temperature use" as used herein means that the composition still has good usability (flow properties) in a "low temperature" environment, i.e. the pour point temperature of the composition does not exceed the "low temperature" environment. In the present invention, "low temperature" means not higher than 5 ℃ and may be, for example, 4 ℃, 3 ℃, 2 ℃, 1 ℃, 0 ℃, -1 ℃, -2 ℃, -4 ℃, -8 ℃, -10 ℃, -15 ℃, -18 ℃, -20 ℃, -23 ℃, -26 ℃, -29 ℃, or-32 ℃, or may be as low as-32 ℃.
The animal fiber cleaning agent composition suitable for low-temperature use comprises two nonionic surfactants with structures, and the first nonionic surfactant and the second nonionic surfactant are matched for use, so that the cleaning effect of the animal fiber cleaning agent composition can be synergistically enhanced under a specific proportion, the cleaning efficiency is remarkably improved, and the prepared cleaning agent composition has a low pour point temperature which is-32 ℃ at the lowest and has excellent low-temperature usability.
Preferably, the linear fatty alcohol in the linear fatty alcohol polyoxyethylene ether nonionic surfactant is C 12 -C 14 Straight-chain fatty alcohol.
Preferred of the invention C 12 -C 14 The straight-chain fatty alcohol can effectively regulate the self-oleophylic and hydrophilic balance property of the surfactant, and improve the emulsifying and dispersing capacity after the dirt is separated, so that the cleaning efficiency of the cleaning agent composition is improved.
Preferably, the number of the repeating units of the ethoxy group in the linear fatty alcohol polyoxyethylene ether nonionic surfactant is 5-12, and can be 5, 6, 7, 8, 9, 10, 11 or 12, and the like.
Preferably, the branched isomeric aliphatic secondary alcohol in the branched isomeric aliphatic secondary alcohol polyoxyethylene ether nonionic surfactant is C 10 -C 14 Branched chain isomeric aliphatic secondary alcohols.
