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 (such as wool) are important raw materials for the production of wool in the wool industry. As natural animal fibers, they are contaminated with animal glandular secretions, excretions, and other contaminants (e.g., soil, plant debris, etc.) during their growth. Therefore, the raw animal fibers (raw wool) are subjected to a cleaning and impurity removal operation before textile processing, and grease, sweat and other organic or inorganic impurities attached to the animal fibers are removed. The animal fiber to be cleaned is immersed in water, and the water-soluble pollutants are removed by mechanical agitation or ultrasonic means. However, the water-insoluble oily contaminants present on the fibers generally require the addition of a cleaning agent to the water to remove them to some extent from the fibers. Thus, the fiber cleaning agent plays a very important role in permeation, emulsification, dispersion and deoiling in the animal fiber cleaning process. The cleaning capability of the cleaning agent directly influences the whiteness, the looseness and other characteristics of the washed fiber, and has great influence on the subsequent processing of the fiber and the quality of the product.
However, the general cleaning agent commonly used in the market has the characteristics of low cleaning efficiency, high pour point, easy gelation at low temperature (less than 5 ℃) and poor solubility, and the like, so that great inconvenience is brought to processing equipment and process, and meanwhile, the process cost of low-temperature processing and use is greatly increased. In cold areas with low air temperature, especially in winter, the method has become a main influencing factor for limiting the application of the method. Therefore, the development of animal fiber cleaning agents 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 ethylenediamine tetraacetate, sodium carboxymethyl cellulose, fatty alcohol polyoxyethylene ether and sodium fatty acid methyl sulfonate. The wool cleaning agent can effectively remove dirt in wool and improve the quality of the wool, but is not suitable for low-temperature use.
CN102660392a discloses a wool detergent comprising a natural nonionic surfactant, a fatty polyol with 2-8 carbon atoms, an inorganic ammonium salt stabilizer, and an organic salt preservative. The nonionic surfactant is tea saponin, soapberry saponin, alkyl polyglucoside or sorbitan ester. The residual fat rate of wool washed by the detergent is below 0.5%, but the method needs repeated washing, is time-consuming and labor-consuming, and is not suitable for low-temperature use.
Based on the above study, it can be seen that there is a certain limitation in developing a cleaning agent for animal fur in a low-temperature environment, and the components of the cleaning agent are required to be further optimized. Therefore, the cleaning agent provided by the invention improves the cleaning efficiency of animal fibers in a low-temperature environment, and has great practical significance in the textile processing field.
Disclosure of Invention
Aiming at the defects of 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, and the obtained cleaning agents can be used in a low-temperature environment and can be used for remarkably improving the cleaning efficiency of dirt (such as grease) and impurities in animal fibers.
To achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides an animal fiber cleaner composition suitable for use at low temperatures comprising a nonionic surfactant comprising, by mass percent, 10-75% (e.g., 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., 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 75%, 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 heterogeneous fatty secondary alcohol polyoxyethylene ether nonionic surfactant.
Other values within the above numerical ranges are selectable, and will not be described in detail herein.
By "suitable for use at low temperatures" in the context of the present invention is meant 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. "low temperature" in the present invention means not higher than 5 ℃, for example, 4 ℃, 3 ℃, 2 ℃, 1 ℃, 0 ℃, -1 ℃, -2 ℃, -4 ℃, -8 ℃, -10 ℃, -15 ℃, -18 ℃, -20 ℃, -23 ℃, -26 ℃, -29 ℃, -32 ℃ and the like, and even as low as-32 ℃.
The animal fiber cleaning agent composition suitable for low-temperature use comprises two nonionic surfactants with two structures, and through the matching use of the first nonionic surfactant and the second nonionic surfactant, the cleaning effect of the animal fiber cleaning agent composition can be synergistically enhanced under a specific ratio, the cleaning efficiency is obviously improved, and the prepared cleaning agent composition has low pour point temperature, minimum-32 ℃ and excellent low-temperature usability.
Preferably, the linear fatty alcohol in the linear fatty alcohol polyoxyethylene ether nonionic surfactant is C 12 -C 14 Linear fatty alcohols.
Preferred C of the invention 12 -C 14 The linear fatty alcohol can effectively regulate and control the lipophilic and hydrophilic balance property of the surfactant, and improve the emulsifying and dispersing capacity of the surfactant after dirt is separated, so that the cleaning efficiency of the cleaning agent composition is improved.
Preferably, the number of the ethoxy repeating units in the linear fatty alcohol polyoxyethylene ether nonionic surfactant is 5-12, and for example, 5, 6, 7, 8, 9, 10, 11 or 12 can be used.
Preferably, the branched chain heterogeneous fatty secondary alcohol in the branched chain heterogeneous fatty secondary alcohol polyoxyethylene ether nonionic surfactant is C 10 -C 14 Branched chain heterogeneous fatty secondary alcohols.
Preferred C of the invention 10 -C 14 Branched chain heterogeneous aliphatic secondary alcohol, because the special molecular structure of the aliphatic secondary alcohol can lead the wetting and penetrating properties of the surfactant to be more excellent, and simultaneously can effectively reduce the flow viscosity of the surfactant and increase the applicability of the product at a wider temperature.
