Treatment agent and fiber fabric or coating

Abstract

The present application relates to a treating agent and a treated fiber fabric or coating. The treating agent includes a silicone polymer, an emulsifier, and an aqueous medium, wherein the silicone polymer includes structural units derived from monomer I, which includes a silicon monomer I-A and optionally a silicon monomer I-B, each of which is defined in the specification. The treating agent can simultaneously impart good oil and water repellency to a fiber fabric and good stain or graffiti resistance to a coating.

Description

Technical Field

[0001] This application relates to a treatment agent and the treated fibrous fabric or coating thereof. Technical Background

[0002] In the past, fluoropolymers were used for surface water and oil repellency treatment of fiber fabrics. Because fluoropolymers have low surface tension, they can change the surface properties of fiber fabrics without affecting their appearance, so they have been widely used.

[0003] However, in recent years, the international community has paid increasing attention to polyfluoroalkyl compounds (PFAS).

[0004] In view of the above, some novel non-fluorinated compounds have been proposed to replace existing fluorinated finishing agents.

[0005] CN107849187A proposes a method for copolymerizing acrylates with monomers such as vinyl chloride, resulting in a polymer that, when used to finish textiles, exhibits excellent water-repellent properties.

[0006] CN105765025B proposes a copolymer using long-chain alkyl propylene esters, the resulting polymer exhibiting excellent water-repellent properties when used to finish textiles. CN105764980B and CN 105745272B both employ similar processes to synthesize the treatment agent, achieving the same water-repellent effect.

[0007] CN114573768B proposes a self-dispersible polymer using organosilicon. The resulting polymer can be used to finish fiber fabrics and has both water-repellent and oil-repellent effects, but its water-repellent effect is not outstanding.

[0008] Therefore, there is a need to invent a non-fluorine-based treatment agent that has excellent water-repellent properties and oil-repellent properties, and can effectively combat various water-based and oil-based stains. Summary of the Invention

[0360] Evaluation methods

[0361] Fiber Fabric Test Methods—Water Repellency

[0362] According to Teflon's global specifications and quality control testing methods, samples of fabric were tested using liquids containing different volume fractions of isopropanol to observe and determine the degree of surface wetting. This test provides a rough index of water resistance. A higher repulsion rating indicates better resistance of the final substrate to water-based substances. The composition of the standard test liquid is shown in Table 1 below.

[0363] Table 1 Composition of Water Resistance Test Grades

[0364] Water resistance rating Composition by volume %, isopropanol Composition by volume %, water 1 2 98 2 5 95 3 10 90 4 20 80 5 30 70 6 40 60 7 50 50 8 60 40 9 70 30 10 80 20 11 90 10 12 100 0

[0365] Fiber Fabric Testing Methods—Spray Water Repellency Test

[0366] The dynamic water resistance of treated substrates was determined according to the American Association of Textile and Chemical Operators (AATCC) TM-22 standard, referring to the published guidelines. A glass funnel with a volume of at least 250 mL and a nozzle capable of spraying 250 mL of water over 20-30 seconds were used. The test piece frame was a 15 cm diameter metal frame. Three test pieces, approximately 20 cm × 20 cm in size, were prepared and fixed to the test piece frame, ensuring the pieces were wrinkle-free. The spray was centered on the center of the piece, and 250 mL of room temperature water was added to the glass funnel and sprayed onto the test piece over 25-30 seconds. The frame was then removed from the table, and one end of the frame was held so that the front surface was underside. The opposite end was gently tapped with a hard object. The frame was then rotated 180 degrees. ° Repeat the same steps to allow excess water droplets to fall off. Assign scores of 0, 50, 70, 80, 90, and 100 to the wet test pieces, ranging from poor to excellent water repellency (as shown in Table 2 below). Compare with a wet standard. Obtain the results based on the average of three measurements.

[0367] Table 2 Water Repellency Rating Table

[0368] Water repellency: No. state 100 There is no moisture or water droplets adhering to the surface. 90 The surface is not wet, but small water droplets are present. 80 The surface appears as small, individual water droplets of moisture. 70 Half of the surface is wet, appearing as small, individual wetted permeable fabrics. 50 The surface is generally moist. 0 The surface and back are generally wet.

[0369] Fiber Fabric Test Methods—Oil Resistance

[0370] Oil resistance is evaluated according to the AATCC-TM118 test method. The basic principle is to drop test oils with different surface tensions onto the test cloth. The higher the grade, the better the oil resistance. The composition of the standard test liquid is shown in Table 3 below.

[0397] Comparative Example 2

[0398] In a four-necked flask equipped with a reflux condenser, nitrogen inlet tube, thermometer, and stirrer, add 490 g of deionized water, 135 g of StA monomer, 33 g of dipropylene glycol methyl ether, 6 g of polyoxyethylene isotridecyl ether (EO:18, 18 ethylidene units), 1.5 g of polyoxyethylene isotridecyl ether (EO:3, 3 ethylidene units), and 60 g of octadecyltrimethylammonium chloride (10% solution). Disperse the mixture using ultrasonic emulsification at 60°C for 30 minutes with stirring. After purging the reaction flask with nitrogen, add 2,2... ， A solution of 1.2 g of azobis(2-amidinylpropane) dihydrochloride and 20 g of water was prepared. The mixture was heated to 60 °C and reacted for 10 hours to obtain a polymer emulsion. The solid content was then adjusted to 20% with deionized water.

[0399] Comparative Example 3

[0400] Add 135g of amino silicone oil (ammonia value 0.5mmol / g, viscosity 1200cp (25℃)), 9g of isotridecyl alcohol polyoxyethylene ether (EO number: 9), and 9g of isotridecyl alcohol polyoxyethylene ether (EO number: 5) to a 1-liter plastic cup, stir at high speed, and then slowly add 610g of deionized water (completely added over 30 minutes).

[0402] Table 7 Performance Test Table

[0403]

[0404] The solid content of Examples 1, 2 and 3 was 20%, and the solid content of Comparative Example 1 was 25%. However, the content of silicon monomers or silicon compounds (or long-chain hydrocarbon monomers) in these four examples was basically the same.

[0405] Based on the performance test results in Tables 5, 6, and 7, the polymer emulsions obtained in Examples 1-9 of this application all show good oil and water repellency when applied to fiber fabrics.

[0406] Comparative Example 1 uses the same silicon monomer I as Example 1, but since solution polymerization is used and the product needs to be dissolved in water in the end, more water-soluble monomers are introduced into the structure to aid solubilization. As a result, although the treatment agent of this structure has good oil repellency, its water repellency is significantly insufficient compared with this application.

[0407] Comparative Example 2 used long-chain alkyl monomers as the main reactants, and the results showed that the treatment agent had certain water-repellent properties in the fiber fabric but not oil-repellent properties. Comparative Example 3 used long-chain silicone oil as the raw material, and the results similarly showed that the treatment agent had certain water-repellent properties in the fiber fabric but not oil-repellent properties.
