Description

Technical Field

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

[0002] Cashmere and wool fabrics are highly susceptible to damage from moths during storage and production. For a long time, to reduce moth damage to wool fabrics, people have commonly used sublimable chemicals such as camphor and naphthalene during production and storage, utilizing their volatile toxic gases to inhibit moth growth and infestation. Camphor balls containing dichlorobenzene and naphthalene are classified as pesticides and are generally used for moth control on industrial or agricultural products; they are not suitable for household items. These moth repellents have a short-lasting effect, are not washable, have a strong odor, are highly toxic, and pose certain health risks, including potential carcinogenicity.

[0003] Moth repellents are agents used to prevent, repel, or control wood-boring pests (such as the black-faced bark beetle, the yellow-faced bark beetle, the clothes moth, and the bagworm moth) that damage fur, fiber products, books, and paintings. An ideal moth repellent should meet the following criteria: high lethality against all types of wood-boring insects; non-toxic or with very low toxicity; safe for humans; moderate volatility; and not cause discoloration or deterioration of packaging materials in contact with clothing.

[0004] Dextromethorphan insecticides are a class of synthetic insecticides with chemical structures similar to natural pyrethrin. Pyrethroid moth repellents are all non-water-soluble, and currently, they mainly rely on the adsorption of protein fibers.

[0005] Currently, the domestic wool textile industry commonly suffers from mildew, insect infestation, and bacterial growth in cashmere and wool raw materials, yarns, and finished products. Traditionally, a single mothproofing agent is added during the dyeing process, which is complex and affects colorfastness and hand feel. After dyeing, cashmere and wool fibers undergo various post-treatments to ensure the fiber's hand feel and various fastness indicators. This process washes away a significant portion of the mothproofing agent, resulting in waste and affecting subsequent mothproofing effectiveness. Adding antibacterial auxiliaries during dyeing presents similar problems. Furthermore, adding excessive auxiliaries during the pre-spinning dyeing process negatively impacts the dyeing process. Additionally, antibacterial and mothproofing agents added during dyeing are generally expensive and wasteful, placing a heavy cost burden on enterprises and hindering their price competitiveness. Since most mothproofing and antibacterial agents are insoluble in water, adding them directly during wool blending results in uneven blending, poor effectiveness, and affects spinning, even impacting yarn strength, fiber spinnability, and yield. Summary of the Invention

[0006] Technical problem solved: In view of the above-mentioned technical problems, the present invention provides a water-soluble wool oil and its preparation method and its application in improving the performance of textiles. It can effectively solve the technical problems in the current domestic wool textile industry where traditional mothproofing agents, antibacterial agents and anti-enzyme agents are insoluble in water and are directly added during the wool mixing process, which will cause uneven wool mixing, poor effect, affect spinning, and even affect the strength of yarn, the spinnability of fibers and the yield.

[0007] In a first aspect, the present invention provides a water-soluble form and crude oil, employing the following technical solution: A water-soluble crude oil, and the crude oil components include: polyethylene glycol laurate, sorbitan laurate, polyoxyethylene polyoxypropylene block copolymer, isothiazolinone, castor oil polyoxyethylene ether, and auxiliaries; said auxiliaries are selected from one or two of deionized water or softened water.

[0009] The wool-spun oil provided by this invention is mainly used for protein loose fibers such as cashmere and wool. It is an antibacterial and anti-moth functional oil added during the spinning process. Its main function is to add two functions to the wool-spun oil while maintaining the basic properties of the original wool-spun oil: 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 the absorption method in Appendix D.7 of FZ / T 73023~2006 and has antibacterial properties.

[0010] 2) Mothproof function: When this type of yarn with wool oil is used in the spinning process, the mothproof performance reaches Grade 1A in GB / T 29776~2013, which has excellent mothproof performance.

[0013] Secondly, the present invention provides a method for preparing water-soluble crude oil, employing the following technical solution: A method for preparing water-soluble crude oil includes the following steps: Step 1: Add the base oil agent in the preset proportion to the reaction vessel, start stirring, and mix evenly at room temperature to form a homogeneous oil phase; Step 2: Add the functional oil while continuously stirring; then slowly heat to the specified temperature and stir at a constant temperature to ensure that the functional components react and blend fully. Step 3: Cool the material to room temperature, and slowly add the auxiliary agent while stirring at a uniform speed to fully dilute and hydrate it, ensuring that the homogeneous oil phase system is completely stable; Step 4: Take samples of the blended product for testing. After passing the test, filter the product and then fill it in the correct quantity.

[0014] Preferably, a method for preparing a water-soluble crude oil includes, specifically, a base oil agent comprising: polyethylene glycol laurate, sorbitan laurate, polyoxyethylene-polyoxypropylene block copolymer, isothiazolinone, and castor oil polyoxyethylene ether; the functional oil agent comprising: one or more of natural plant-derived flavonoids, 3-(trimethoxysilyl)propyl dimethyl octadecylamine chloride, and pyrethroids; and the auxiliary agent being deionized water or softened water.

[0015] Preferably, in a method for preparing water-soluble crude oil, specifically, in steps 1 to 3, the stirring time is 15 to 60 minutes, the stirring speed is 30 to 50 rpm, and the mass fraction of the auxiliary agent is 5 to 20%.

[0021] 2. The raw materials selected in the preparation process of the water-soluble and crude oil provided by this invention, as well as the control of the production process, are required to ensure that the prepared crude oil does not affect or helps the cohesion, permeability, antistatic properties, lubricity, and moisture regain of the yarn required in the cashmere and wool spinning process.

[0022] 3. Compared with existing yarn-making oils on the market, the water-soluble yarn-making oil provided by this invention can meet the general usage conditions of spinning, such as: good penetrating and wetting properties, certain fiber bundling and cohesion, certain antistatic properties, certain lubrication to facilitate fiber combing, and certain moisture regain of the yarn. While meeting general usage conditions, it also imparts antibacterial and moth-proof effects, filling a gap in the industry and solving a key industry problem. Detailed Implementation
