Description

Technical Field

[0001] This invention belongs to the field of clothing fabric technology, specifically relating to a fluorine-free, plant oil-resistant, stain-resistant, easy-to-clean, and water-permeable clothing fabric and its production process. Background Technology

[0002] In addition to comfort, people now demand that clothing fabrics be aesthetically pleasing, clean, and easy to care for. In work, daily life, and dining settings, fabrics should be able to easily shake off dust and oil stains without leaving a residue. For sticky, pasty sauces, they can be wiped off and rinsed with water for a quick and easy clean. For stains that have been on the body for a long time, such as sauces and oils that have seeped in, a washing machine can thoroughly clean them in one go, ensuring the fabric is clean, aesthetically pleasing, and easy to care for from front to back. During wear, the fabric also needs to be breathable and sweat-wicking to prevent sweat buildup that clings to the body, affecting appearance and causing a stuffy feeling.

[0003] Fluorine-based, waterproof, and stain-resistant fabrics can provide oil and stain resistance. Some waterproof and stain-resistant fabrics can sacrifice some water and oil resistance to achieve both stain resistance and easy stain removal. However, sweat cannot penetrate these fabrics, and they have poor washability, affecting the wearing experience. Meanwhile, fluorine-based clothing fabrics contain PFAS (per- and polyfluoroalkyl substances), which pose health and environmental hazards. Driven by tightening global regulations, increased consumer environmental awareness, and brand technological innovation, they are currently undergoing a complete "de-fluorination" transformation. Currently, hydrophilic, fluorine-free, and stain-resistant fabrics offer good hydrophilicity and easy stain removal, but they cannot simultaneously provide oil and stain resistance. In work and daily life settings, they easily attract stains that are not easily and quickly removed, affecting their appearance.

[0004] Patent CN112267299A discloses a production process for a three-proof (waterproof, stain-resistant, and shockproof) and easy-to-clean fabric. After the greige fabric is cleaned in a treatment solution containing detergent and fabric protectant, it is then impregnated with a three-proof and easy-to-clean finishing solution in the finishing groove of a setting machine. While this invention improves the synergistic effect of three-proof properties and easy-to-clean properties, as well as water resistance, through hyperbranched polymers, the three-proof finishing inevitably affects the fabric's water permeability, causing sweat to accumulate easily during wear, resulting in decreased aesthetics and comfort. Furthermore, the fabric contains fluorine, which does not comply with new environmental regulations.

[0005] Patent CN117328190A discloses a method for preparing a fluorine-free waterproof and stain-resistant fabric. The warp and weft yarns are impregnated with a fluorine-free finishing agent for 30-45 minutes and then dried. After being woven into a base fabric, it is then impregnated and rolled with a waterproof and stain-resistant finishing agent, followed by drying and shaping. While this invention improves the waterproof rating to level 5 by treating both the yarn and the base fabric, providing some protection against water-based stains, its oil-resistant properties are weak. It has limited effectiveness against high-viscosity oil stains, allowing oil to penetrate the fabric more easily and spread after staining. The excellent waterproof performance also prevents water from penetrating the fabric, increasing the difficulty of cleaning.

[0006] Patent CN116289217A discloses a fluorine-free waterproof and oil-repellent finishing agent for textiles, its preparation method, and its application. Fuco Company achieves copolymerization of reactive organosilicon, end-capped isocyanate, and nanoparticles through emulsion polymerization, followed by a dip-pad-dry process to finish the fabric surface. This process creates a low surface energy interface and nanoscale surface roughness on the fiber surface, giving the fabric waterproof, corn oil-repellent, and soy sauce-repellent properties. While this additive and finishing process offer excellent protection against vegetable oils and can handle most oily stains from everyday food contact, its waterproof performance makes the fabric difficult to soak into and results in poor stain removal.

[0007] Based on consumers' demand for a neat and tidy appearance in clothing in daily life scenarios, there is currently a need for a fluorine-free fabric that is both oil- and stain-resistant, easy to clean, and also breathable and sweat-wicking without affecting the wearing experience. Summary of the Invention

[0008] This invention provides a fluorine-free, plant oil-resistant, stain-resistant, easy-to-clean, and water-permeable clothing fabric and its manufacturing process. The finished fabric possesses plant oil-resistant properties, effectively preventing oily stains from penetrating quickly and allowing oil droplets to be easily shaken off. For viscous sauce stains, wiping and rinsing with water can quickly clean them. At the same time, it can thoroughly clean stains that have soaked into the fabric in a single machine wash. The excellent water permeability effectively avoids the sticky and hot feeling caused by sweat accumulation during wear and prevents clothing from sticking to the body and affecting appearance, thus improving the comfort of wearing the fabric.

[0009] The technical solution of this invention is as follows: The first aspect discloses the production process of fluorine-free, vegetable oil-resistant, stain-resistant, easy-to-clean, and water-permeable garment fabrics, including the following steps: fabric pretreatment → high-temperature functional padding → pickling → low-temperature functional padding → stacking reaction → baking → pre-shrinking. The high-temperature functional rolled material is dipped in a fluorine-free, waterproof, and oil-proof functional liquid on a tenter frame. The dipping and rolling process is one dip and one roll, with a rolling mill residual rate of 55-70%, a machine speed of 20-40 m / min, and a drying oven temperature of 160-170℃. The pickling is carried out on a washing machine, which includes washing tanks 1 to 8. The temperature of washing tanks 1 to 8 is 40±2℃. Neutralizing acid is added to washing tank 1 at 2 to 5 g / L. The speed of the washing machine is 50 to 60 m / min. The low-temperature functional fabric is dipped in a fluorine-free, hydrophilic, and easily cleanable functional liquid in a stacking tenter frame. The dipping and padding process is one dip and one pad. The fabric is stacked and soaked in the stacking tank for 1-2 minutes. The padding machine has a padding rate of 55-70%, a machine speed of 20-40 m / min, a temperature of 70-90℃ in each section, and a fabric moisture content of 10-20%. The temperature of the stacking reaction is 35–45°C, and the time is 2–4 hours.

[0010] Preferably, the fluorine-free waterproof and oil-repellent functional liquid is composed of a fluorine-free waterproof and oil-repellent finishing agent, a fluorine-free oil-repellent crosslinking agent, and water; the fluorine-free waterproof and oil-repellent finishing agent is prepared by emulsion polymerization using acrylate monomers containing silane structures, isocyanate monomers containing carbon-carbon double bonds, and acryloyloxypropyl cage-type polysilsesquioxane as raw materials; the fluorine-free oil-repellent crosslinking agent is prepared from isocyanate homopolymers; the dosage of the fluorine-free waterproof and oil-repellent finishing agent is 60-100 g / L, and the dosage of the fluorine-free oil-repellent crosslinking agent is 10-20 g / L; more preferably, the fluorine-free waterproof and oil-repellent finishing agent is X-8801, and the fluorine-free oil-repellent crosslinking agent is AX-101Z.

[0011] Preferably, the fluorine-free hydrophilic and easy-to-clean functional liquid is composed of a fluorine-free hydrophilic and easy-to-clean finishing agent and water; the fluorine-free hydrophilic and easy-to-clean finishing agent is an emulsion of a high molecular weight polymer, containing a hydrophobic polyester main chain and long-chain polyoxyethylene hydrophilic side chains; the amount of the fluorine-free hydrophilic and easy-to-clean finishing agent is 30-60 g / L; more preferably, the fluorine-free hydrophilic and easy-to-clean finishing agent is -D90S-C.

[0012] Preferably, the fabric pretreatment includes singeing, desizing, mercerizing, and liquid ammonia. The singeing is performed on both sides, directly, at a speed of 70~100m / min; The desizing is performed using an enzyme, specifically a high-temperature desizing enzyme DS-HT, with an enzyme dosage of 10-30 g / L, a temperature of 95-100℃, and a machine speed of 70-100 m / min. The concentration of the mercerizing alkaline solution is 5~15Be, the temperature of the alkaline solution is 20~30℃, and the speed of the machine is 50~80m / min; The liquid ammonia steam temperature is 100~120℃, the vehicle is washed with room temperature water, and the speed is 40~70m / min.

[0013] Preferably, the baking is carried out in a baking machine at a temperature of 140-150°C and a speed of 40-60 m / min.

[0014] Preferably, the pre-shrinking speed is 40-60 m / min, the blanket temperature is 110-130℃, and the shrinkage rate is 1-4%.

[0015] Secondly, the process described above produces fluorine-free, plant oil-resistant, stain-resistant, easy-to-clean, and water-permeable clothing fabrics.

[0016] The mechanism of fluorine-free waterproof and oil-repellent properties lies in constructing a waterproof and oil-repellent film with a "low surface energy oriented arrangement and micro-nano rough structure" on the fabric surface, utilizing the lotus leaf effect to achieve oil and stain resistance. The mechanism of hydrophilic and easy-to-clean properties lies in constructing a "highly hydrophilic film" on the fiber surface. The application principles of waterproof and oil-repellent and hydrophilic and easy-to-clean properties are opposite. The superposition of the hydrophilic film formed by ordinary hydrophilic and easy-to-clean additives and the waterproof and oil-repellent film will weaken the oil-repellent and easy-to-clean properties of both.

[0017] To address this challenge, this invention preferentially employs a fluorine-free, hydrophilic, and easily detergency-resistant finishing agent with a special hydrophobic polyester main chain and long-chain polyoxyethylene (PEO) hydrophilic side chains. The hydrophilic PEO groups of this additive can directly insert into the gaps in the waterproof and oil-repellent membrane, while the hydrophobic main chain covers the oil-repellent membrane, forming a "double-membrane embedded structure." In the dry state, the hydrophobic main chain and the micro-nano rough structure of the oil-repellent membrane work synergistically to repel oil, mutually enhancing the anti-fouling performance against vegetable oils. When exposed to water, the PEO hydrophilic groups turn outward, reducing the fiber-water interfacial tension. Simultaneously, when the hydrophilic PEO groups insert into the waterproof and oil-repellent membrane, they can disrupt the membrane's density and continuity without affecting the fabric's micro-nano rough structure. This weakens the waterproofness without compromising its oil-repellent properties, synergistically accelerating fiber wetting and penetration, making it easier for oil stains to separate from the fibers.

[0018] To address the issues arising from the first step of waterproofing and oil-repellent finishing in the fabric processing—namely, the waterproofing of the fabric in the first step—leading to poor penetration of the hydrophilic and easily detergency additives in the second step, uneven reaction, and the weakening of the conflicting functionalities between the two processes, this invention adds pickling, piling, and moist piling processes to the conventional three-proof or easily detergency finishing process of padding → drying → baking. A. Pickling: After the first step of waterproofing and oil-repellent finishing, a light pickling process is performed at around 40℃. This pickling process can make the fabric fluffy and increase the internal porosity of the fabric, which is conducive to the fabric's water absorption. At the same time, the 40℃ light pickling can disrupt the continuity of the waterproof film on the fabric surface to a certain extent, but it does not affect the surface micro-nano rough structure. This weakens the fabric's waterproofness without affecting its oil-repellent properties, which is conducive to the penetration of the finishing solutions in subsequent functional finishing processes.

[0019] B. Stacking and Rolling: The first step, high-temperature functional rolling, first constructs a waterproof and oil-proof film on the fabric surface, giving the fabric oil-proof and waterproof properties. To ensure that the hydrophilic and easily cleanable liquid in the second step can fully penetrate the fabric, after pickling, a stacking tenter frame with a stacking soaking tank is used for finishing, so that the fabric is soaked and stacked in the tank, which improves the fabric's absorption of auxiliaries.

[0020] C. Moist Packing Reaction: After the second step of low-temperature hydrophilic and easily decontaminated rolling, the material is dried at a low temperature and then piled at a certain humidity of about 35~45℃ for 2~4 hours. Moist packing allows the additives to fully migrate and penetrate into the fiber pores, making the reaction more uniform and facilitating full bonding with the oil-resistant film inside the fiber. This avoids the problem of the additives failing to penetrate due to "surface drying" caused by excessively rapid baking.

[0021] Fabrics produced through a combination of high-temperature and low-temperature step-by-step rolling, pickling, and stacking reaction processes exhibit excellent protective properties against macromolecular plant oils and sauces and broths containing plant oils. Simultaneously, the weakening of water resistance by auxiliaries and finishing processes gives the fabric low-pressure permeability and excellent stain-removing properties.

[0022] Compared with the prior art, the present invention has the following advantages: 1. The fabric produced by this invention has excellent resistance to plant oils, stain resistance, easy stain removal, and water permeability. It overcomes the inability to simultaneously achieve oil resistance, stain resistance, and easy stain removal in daily wear. At the same time, the excellent water permeability allows sweat generated during wear to be easily squeezed out of the body through the clothes, effectively avoiding the sticky and hot feeling caused by sweat accumulation and the clothing sticking to the body and affecting the appearance, which is conducive to improving the wearing comfort of the fabric.

[0023] 2. The fabric specifications produced by this invention are as follows: Water permeability (water pressure resistance): ASTM D751-2006-B method; 1-5 seconds before washing, 1-5 seconds after 10 washes; Easy to clean: AATCC130 corn oil / peanut oil; Grade 4 before washing, Grade 3.5 or higher after 10 washes; For protection against vegetable oils: GB / T30159.1 corn oil / peanut oil; Grade 5 before washing, Grade 4 or above after 10 washes; Stain-resistant - Oil-red: JIS L1919C drip method; Grade 3.5 or higher before washing, Grade 3.5 after 10 washes; Dynamic anti-fouling - Ketchup: JISL1919C method extension, rinse with water for 1 minute within 30 seconds after applying ketchup; Level 4 before washing, Level 3.5 or above after 10 washes.

[0033] Comparative Example 1 The difference between this comparative example and Example 1 is that the fabric production process is a conventional three-proof finishing process, including the following steps: fabric pretreatment (singeing-desizing-mercerizing-liquid ammonia) → functional padding → drying → baking → pre-shrinking, wherein, The fabric used, as well as the fabric pretreatment, baking, and pre-shrinking processes, are the same as in Example 1. The additives used in the functional rolled material are CLEAN (80 g / L waterproof and oil-repellent agent) and FNN (10 g / L three-proof reinforcing agent); the drying temperature is 110℃.

[0034] Comparative Example 2 The difference between this comparative example and Example 2 is that the fabric production process is a conventional fluorine-free, easy-to-clean finishing process, including the following steps: fabric pretreatment (singeing-desizing-mercerizing-liquid ammonia) → functional padding → drying → baking → pre-shrinking, wherein, The fabric used, as well as the fabric pretreatment, baking, and pre-shrinking processes, are the same as in Example 2. The additive used in the functional rolled material is 80 g / L of fluorine-free hydrophilic and easy-to-clean detergent TF-9901B, and the drying temperature is 115℃.

[0035] Comparative Example 3 The difference between this comparative example and Example 3 is that the fabric production process is a conventional three-proof and easy-to-clean finishing process, including the following steps: fabric pretreatment (singeing-desizing-mercerizing-liquid ammonia) → functional padding → drying → baking → pre-shrinking, wherein, The fabric used, as well as the fabric pretreatment, baking, and pre-shrinking processes, are the same as in Example 3. The additive used in the functional rolled material is TG-9031, an anti-fouling and easy-to-clean additive, with a dosage of 90 g / L and a drying temperature of 110℃.

[0036] The fabrics prepared in the above embodiments and comparative examples were tested for easy stain removal, resistance to vegetable oils, stain resistance, dynamic stain resistance, and water pressure resistance. The test standards are shown in Table 1.

[0037] Table 1

[0038] The fabric test results for the examples and comparative examples are shown in Table 2.

[0039] Table 2

[0040] Table 2 shows the experimental results. Comparative Example 1, the conventional three-proof finished fabric, has poor stain removal performance (both before and after washing are grade 1). Under certain pressure, the fabric is not permeable to water, and sweat cannot be squeezed out during wear, reducing the wearing experience. Example 1, on the other hand, shows easily repellent (corn oil, peanut oil) fabric at grade 4 before and after washing, vegetable oil repellent (corn oil / peanut oil) at grade 5 before and after washing, stain repellent - oil red at grade 4 / 3.5 before and after washing, and dynamic stain repellent - tomato sauce at grade 4 before and after washing. All fabrics meet functional requirements, and their water pressure resistance and permeability are 3S before and after washing. Sweat can be quickly squeezed out through the fabric, resulting in a good wearing experience.

[0041] Comparative Example 2: The fluorine-free hydrophilic and easy-to-clean fabric had no plant oil resistance (both before and after washing were level 1), and poor stain resistance (both before and after washing were level 3 or below). During garment wear, stains easily adhered and could not be removed promptly, affecting the garment's appearance. Example 2: The easy-to-clean fabric (corn oil, peanut oil) had a level of 4 / 3.5 before / after washing; the plant oil resistance (corn oil, peanut oil) had a level of 5 before / after washing; the stain resistance for oily red stains had a level of 3.5 before / after washing; the dynamic stain resistance for tomato sauce stains had a level of 4 before / after washing; and the water pressure and permeability resistance had a level of 3S / 2S before / after washing. Both the functional effects and the water pressure and permeability resistance were satisfactory.

[0042] Comparative Example 3: While the three-proof and easy-to-clean fabric possesses easy-to-clean properties, it exhibits poor oil resistance, poor washability for both stain resistance and easy-to-clean (corn oil, peanut oil) stains, and is not water-permeable, preventing sweat from being squeezed out through the garment, resulting in a poor wearing experience. Example 3: Easy-to-clean (corn oil, peanut oil) stain resistance before / after washing was level 4 / 3.5; plant oil (corn oil, peanut oil) stain resistance before / after washing was level 5; stain resistance - oil red stain resistance before / after washing was level 3.5; dynamic stain resistance - tomato sauce stain resistance before / after washing was level 4 / 3.5; water pressure resistance and permeability before / after washing were 3S / 5S. Both functional effects and water pressure resistance and permeability were satisfactory.

Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the invention, and such modifications or substitutions should all be within the scope of the invention.
