Description

Technical Field

[0001] This invention belongs to the field of textile auxiliaries, specifically relating to an emulsified wool oil, its preparation method, and its application in improving the performance of textiles. Background Technology

[0002] Wool fiber, as an important textile material, is widely used in clothing, high-quality carpets, and other applications due to its excellent dyeability, high elasticity, and comfort. However, wool fiber also has some problems, such as felting caused by the scales on the fiber surface, making it prone to bacterial growth and moth damage.

[0003] Fur, fiber, books, and paintings are easily damaged collectibles, making them susceptible to infestation by pests such as black bark beetles and clothes moths. Cashmere and wool fabrics are particularly vulnerable to moth damage during storage and production. The main enemies of protein fiber fabrics like cashmere and wool fall into two categories: clothes moths (Lepidoptera) and bark beetles (Coleoptera). Both feed on keratin, and cashmere and wool are keratin fibers, making cashmere and wool fabrics prime targets for these moths. To protect these items from moth damage, moth repellents must be used for prevention, repellency, and control.

[0004] Industrial textiles contain sizing agents and fats, making them highly susceptible to microbial growth. Bacteria, actinomycetes, and molds secrete enzymes that can decompose fibers, damaging them. Cashmere yarn, a high-end textile fiber often referred to as "soft gold," commands a high price, currently ranging from 900,000 to 1,000,000 yuan per ton. If cashmere or wool yarn becomes infested with insects, develops mold, or breeds bacteria, rendering it unusable, it will result in significant losses for businesses. Furthermore, since cashmere and wool are natural fibers, such unusable yarn represents a severe waste of resources.

[0005] Currently, the traditional textile industry commonly faces problems in functional finishing processes, such as the use of single-component auxiliaries and complex addition processes. This not only limits the stability and uniformity of dyeing effects but also affects the overall quality of the fabric. Particularly in functional finishing processes such as mothproofing, antibacterial properties, and mildew resistance, the auxiliaries used are prone to dissolution and loss during subsequent washing, leading to a significant waste of effective ingredients. This not only reduces the durability of the function but also increases the frequency of repeated additions. Furthermore, traditional auxiliaries have weak adhesion to fibers, affecting the mothproofing, antibacterial, and mildew resistance of the final product, making it difficult to meet the ever-increasing market demands. Summary of the Invention

[0006] The technical problems to be solved are that traditional textile auxiliaries have simple components, complex processes, low fixation durability, and poor anti-moth, antibacterial, and anti-mildew properties. To address these technical problems, this invention provides an emulsified wool oil, its preparation method, and its application in improving textile performance, achieved through the following technical solution: In a first aspect, the present invention provides an emulsified crude oil, employing the following technical solution: An emulsified crude oil, and crude oil components comprising: mineral oil, methyl 9-octadecenoate, fatty acid polyoxyethylene ether, castor oil polyoxyethylene ether, sorbitol oleate, isothiazolinone, permethrin, polyethylene glycol laurate, and an adjuvant selected from one or both of deionized water or softened water.

[0008] Preferably, the components of the emulsified and crude oil also include: natural plant-derived flavonoids or 3-(trimethoxysilyl)propyl dimethyl octadecyl chloride.

[0009] The emulsified wool oil provided by this invention is mainly used in the spinning of protein loose fibers such as cashmere and wool. It is an antibacterial, anti-moth, and anti-mildew functional wool oil added during the spinning process. Its main function is to add three functions to the original wool oil while maintaining its basic properties: 1) Antibacterial function: When this type of yarn with lint is used in the spinning process, it has a good inhibitory effect on Staphylococcus aureus and Candida albicans, which meets the standard requirements of Appendix D.7 Absorption Method of FZ / T 73023-2006 and has antibacterial properties.

[0010] 2) Insect and moth resistance: When this type of yarn with wool oil is used in the spinning process, its insect and moth resistance performance reaches Grade 1A in GB / T 29776-2013, which has excellent insect and moth resistance performance.

[0011] 3) Anti-mold function: When this type of yarn with lint is used in the spinning process, its anti-mold performance reaches level 0 of the GB / T24346-2009 standard. Under magnification, there is no obvious mold growth, which meets the anti-mold requirements.

[0012] Preferably, the mass fractions of the emulsified and crude oil components are: mineral oil 20-25%, methyl 9-octadecenoate 12-30%, fatty acid polyoxyethylene ether 10-25%, castor oil polyoxyethylene ether 5-15%, sorbitol oleate 2-10%, isothiazolinone 0-8%, permethrin 0-10%, polyethylene glycol laurate 2-10%, and auxiliary agents 5-15%.

[0013] Preferably, the mass fractions of the emulsified and crude oil components are: 0-6% natural plant-derived flavonoids and 0-6% 3-(trimethoxysilyl)propyldimethyloctadecylamine chloride.

[0014] Secondly, the present invention provides a method for preparing emulsified crude oil, employing the following technical solution: A method for preparing emulsified crude oil includes the following steps: Step 1: Add all the base oil to the reactor, turn on the stirrer, and mix at room temperature until homogeneous; Step 2: Under uniform stirring, add various functional oils in sequence, and continue stirring until all components are evenly dispersed to form a preliminary emulsion; Step 3: While stirring, add the auxiliary agent. Continue stirring for the specified time to ensure the emulsion system is completely stable; Step 4: Conduct a quality inspection on the final emulsion. After passing the inspection, the emulsion undergoes a filtration process to remove impurities before being filled.

[0015] Preferably, a method for preparing emulsified crude oil includes, specifically, a base oil comprising mineral oil, methyl 9-octadecenoate, fatty acid polyoxyethylene ether, castor oil polyoxyethylene ether, sorbitol oleate, isothiazolinone, permethrin, and polyethylene glycol laurate; the functional oil comprising natural plant-derived flavonoids and 3-(trimethoxysilyl)propyldimethyloctadecylamine chloride; and the auxiliary agent being deionized water or softened water.
